How to run bios on acer laptop. how to enter bios on acer laptop Is it worth going into the settings

No matter how perfect our laptop works, over time it starts to slow down. This is affected by the piling up of programs of various kinds, games and applications. Therefore, many decide on rather desperate measures - reinstalling the operating system. On the other hand, some simply do not have enough hardware power in applications or games. In this regard, we decided to tell you about how to enter BIOS on Acer laptops. Thanks to our instructions, you will not encounter any difficulties in the process.

Key combination as a way to get into the BIOS

It doesn't matter if you want to reinstall the OS, are going to overclock the processor or increase the frequency at which the RAM works - we will definitely help you enter the BIOS, where you can do all this. So, you must do the following:

As you can see, the process is really extremely simple. However, there are some nuances here too. For example, different keys may be used on different models. Moreover, keyboard shortcuts can also be used. Thus, on older devices, you can get into the BIOS by simultaneously pressing CTRL + Alt + Esc, on others - F1.

What to do if none of the options fit?

Have you tried every way to enter the BIOS suggested above, but none of them worked? Then we advise you to pay attention to what is written below when starting the laptop. As a rule, developers indicate there:

Button to start system recovery (aka Recovery);

Key for troubleshooting;

laptop configuration.

You need to pay attention to the item called "Setup" or "Setup BIOS". If the options above do not fit, it is possible that your laptop uses one of the following keys to access the BIOS: Esc, Tab, F8, F10 or F12.

We still do not recommend you do this if you are not sure that you understand its device, the BIOS on acer laptops. The fact is that an inexperienced user can knock down the settings and then it will be problematic to restore them on their own. If you just want to reinstall the system, then it's better to use the regular Boot Menu.

If the laptop begins to noticeably slow down or the operating system loads much slower than usual when the device is turned on (or even does not load at all), then the best cure for the disease, as a rule, is restoring the system or completely reinstalling it. There may be several reasons for such incorrect behavior of the OS: incorrect operation of one of their applications, errors in Windows 7 or 8 versions, excessive clogging of the registry and system areas of the hard disk with unnecessary ballast.

How, without resorting to the help of a specialist, to “repair” Windows on an Acer laptop yourself, will be discussed further.

Bios is the heart of the computer

With the complete collapse of windows, the user has only one thing to do - restore the system from a DVD or USB drive. In order for an acer laptop to understand what you want from it, you must explicitly tell it about it.

The fact is that any computer equipment, including acer computers, is equipped with a special factory microcircuit, the read-only memory device of which contains a set of microcommands, referred to in one word - BIOS.

The power button just launches the necessary BIOS procedures, under the control of which all existing nodes of the device are put into operation, and the installed OS is directly searched for.

What is the BIOS for? It is responsible for providing system access to the hardware elements of the computer and external peripherals.

The factory settings of the Acer laptop provide that when it is turned on, the BIOS first scans the hard drive for an operating system, then the CD drive, and then the rest of the potential devices. Trying to find a faulty Windows 7 or 8 on the hard drive in your case, the BIOS freezes - the user throws up his hands in bewilderment, looking at a blank screen.

You will have to explicitly tell the laptop that, first of all, it will be necessary to scan not the HDD, but your CD drive with the installer or resuscitator of windows 7 or 8 versions.

Welcome to Settings

When starting the laptop, as soon as the "Acer" logo appears on the screen, press "F2" (in some models "F1" or "Ctrl + Alt + Esc"). The BIOS setup window will appear on the display with a set of options. First of all, using the navigation keys, you need to go to the “Main” option and set the “F12 Boot Menu” value to the “enabled” state, which will later allow you to change, restore and save the settings.

Next, go to the "Boot" item. Look at the list of laptop media, which should contain several names: hard drive, cd drive, and usb devices. To reinstall the system from a DVD, select this position from the list and use the "F6" key to move it to the very top.

That's all. You have just explicitly indicated that the system will boot from the optical disk.

Press "F10" to save BIOS settings. After rebooting, the laptop will first turn to your optical drive with the windows installer on it.

When everything is installed and working for you in a new way, go back to BIOS and change the “Boot” menu, setting the initial boot from the HDD.

Unforeseen malfunction

If the OS is terribly slow, but still starts, try resetting the operating environment to factory settings using the built-in Acer eRecovery Management program (in new versions of windows 8 it is called Acer Recovery Management). In order not to waste time looking for it, press the "win" key and enter the name of the application.

The window that appears on the display will offer 3 different options:

as will be seen by definition, system restore will return your equipment to its original state, during which all user data will be destroyed and the laptop will return to the factory settings that it had when it was first started.
the option offers to restore the system with the preservation of certain documents and applications. The process, in principle, is similar to the first option, however, the necessary information on the disk will be saved after recovery.
this mode is needed to reinstall applications and drivers on an Acer laptop.

What you need to solve the problem is contained in the first two paragraphs. The first option has the most effective action, the result of which, after deleting all the information, will return the laptop to factory settings. In order not to lose important information, before the recovery process, save it on an optical disc, USB flash drive or on a cloud server. Such user data means personal photos, video clips, text and other documents. Programs and applications installed during the entire period of using the device will be deleted.

What do the points mean

When choosing the first menu item, follow the instructions of the application and humbly wait for the result. This procedure is used when the OS has almost completely "fallen".

To restore the system while preserving your user account data, use the second mode "restore with preservation".

If window 7 or 8 cannot boot at all, or does not respond to user actions at boot, call the recovery program using a hotkey combination. To do this, when you turn on the laptop and the "Acer" logo appears on the screen, press "alt" + "F10" at the same time. Such magical manipulations will cause the Acer Recovery (eRecovery) Management application to work before the main OS is loaded.

Be careful and do not miss this important moment when you turn on your computer!

Recovery points

Another way to force the device to recover is to use system restore points. The developers of Windows 7 and 8 versions provided an excellent opportunity to "remember" the state of the computer at one time or another and restore the OS, returning it to this state. As a rule, such “security islands” are installed automatically once a week, as well as when the laptop configuration is explicitly modified, for example, when installing a new application or driver.

To use this option, you need to go to the "Control Panel", select the "System Restore" item and the checkpoint whose creation date suits you. When you select the appropriate item, following the instructions of the electronic assistant, you reconstruct your OS without losing user data. In the same program, you have the opportunity at any time to create a different restore point on your laptop.

If no restore points are found in the laptop, you will have to use other methods and possibilities to restore the crashed Windows of your electronic friend.

Many people think about how computer technologies work, and some simply use a laptop, tablet or personal computer, completely unaware of the processes and modes of operation. As a rule, the second occurs until the equipment makes itself felt by any breakdown. For those who have ever entered the BIOS, it is clear that there are a lot of settings in the computer.

How does the operating system work? Quite a difficult question. After all, not everyone knows how this very operating system is arranged and what it serves for.

An operating system (OS) is a set of programs that enable a user to control their computer. The task of the OS is to fulfill all the requirements for downloading and opening programs. You can control the operating system with special settings that are stored in the BIOS.

What is a BIOS?

The BIOS is the fundamental system of your computer

The BIOS is a special system that determines the progress of the computer boot process. BIOS is considered the basic system for input and output of information. The full BIOS decoding speaks for itself: basic (basic) input (input) / output (output) system (system). In order to proceed with the settings, you need to go into the BIOS.

The BIOS is stored on a chip and has a wide range of purposes:

The initial startup of a computer that will subsequently launch the operating system.
Performs routine testing of various parts of a personal computer.
With the help of software interrupts in the BIOS, the input and output function is supported.
Stores the hardware configuration of various individual devices and the entire computer system. This happens with the help of special settings (BIOS Setup).
The BIOS code is located on the system board and is written to the flash memory (microchip).

From this it follows that the BIOS is an integral part of any computer. However, as a rule, the average user does not understand . It is closer to programmers. However, BIOS sometimes does not work correctly, and there may be some reasons for this.

Problems and Solutions

Problems that can cause the BIOS to work incorrectly:

When starting the computer system, an error appears that prevents it from turning on.
Devices are not recognized on the computer or laptop.
Periodic failures that are caused by the instability of the system.
The operating system does not load.

Very important . This will help you avoid many problems. To do this, you need to go into BIOS and take a few steps:

Power on the computer. Then, from the moment the logo appears on the screen, you must immediately press the DEL or F2 key. This action will open the BIOS. The screen should turn blue.
If the BIOS is still not loaded, then you need to press F9. Then it is very important to go to the settings called Load Default Settings. You can control using the arrows on the computer.
The F10 key will save all changes.

What is BIOS Setup?

BIOS Setup are settings that allow you to enter the BIOS system and configure options. Users who solve any problem with a computer deal with BIOS Setup. Translated from English, setup means "settings". This section is managed using certain options and tasks.

Sometimes it happens that the computer fails. Many problems can be solved by the user. It is known that masters require a significant amount of money for a visit, that is, primitive knowledge of the BIOS settings system allows a person to save both time and money. Moreover, some secrets will improve computer performance. Most of the errors that occur in the computer are in the BIOS.

Initially, this system was supposed to control the keyboard and mouse, but over time, functions were added to it. These figures are constantly growing.

BIOS stores writable chips. Two types are known today:

EEPROM chips. You can remove the contents with an electrical signal. To do this, it is not at all necessary to remove it from the computer.
EPROM chips. You can remove data using ultraviolet radiation. For this, a special device is used. However, this technique is now considered obsolete.

Modern computers contain not only a BIOS system improved with functions, but also advanced features of the motherboard as a whole. That is, a sound card, a video card, and so on. In such computers, you can disable or allow the use of boards in the settings. I went into the BIOS - allowed everything necessary.

What settings does the system BIOS contain?

Modern computers in BIOS motherboards contain a lot of different settings that can be changed if you go into BIOS:

Set the calendar date and time of the system clock.
Setting up peripherals that are not designed to work in plug and play mode
Disable or enable onboard hardware on the motherboard. For example, built-in sound or video adapters, as well as LPT, COM and USB ports.
Starting equipment in a gentle or forced mode or resetting the settings to factory settings.
Speeding up the operating system by disabling some tests.
The ability to enable bypass branches to eliminate visible errors in the operating system.
Creating a queue of media from which the computer boots. This includes the hard drive or CD-ROM. All possible options can be installed if you go into the BIOS. If any one possibility fails, then the BIOS automatically tries all the other options in turn.

In today's world, computers are used almost everywhere. Someone uses them for work, and someone organizes their leisure time. But every person wants his computer to work perfectly. That is why it is very important to refer to the settings in the BIOS (Bios Setup) in a timely manner. If the BIOS is working correctly, then the computer does not arouse suspicion (does not slow down, does not freeze, does not give errors in the OS). If the BIOS settings are not set properly, then numerous failures occur. This issue can be resolved in two ways:

Log in and reset all settings to factory defaults.
Try to understand the problem and find the cause of the failure.

BIOS setup on Acer laptop

In computers, it is always easier to replace a part that has failed. In a laptop, things are much more complicated. Therefore, those who constantly work with a laptop just need to understand the BIOS settings.

Consider these settings on an Acer laptop.

Knowledge of the English language will help a lot here, but if you don’t have them, then it’s enough just to understand what the main words (options) mean. In order to, you need to press the hot keys DEL or F9.

EXIT - exit and save settings in BIOS.
BOOT - the ability to select a priority device that will boot the system.
SECURITY - the ability to set passwords to enter the BIOS settings.
MAIN is the main setup menu for working with BIOS settings, which contains all the mechanisms for managing a laptop.
INFORMATION is information about the state of the laptop and all settings related to it in BIOS.

You don't have to read too much into the information. It is enough just to correctly set the calendar date and time. It is also worth checking the temperature of the processor and comparing it with normal parameters. If it is higher, then it is best to let the laptop cool down. Laptop heating is a very common problem. That is why now there are special stands that cool the processor in an Acer laptop. In this section, you can also check which devices are connected to the laptop.

The situation is much more complicated with the MAIN section, since it controls all processes.

System Time - system time.

System Date - system date.

System Memory - system memory. The amount of memory cannot be changed, it only shows information.

Video Memory - the amount of video memory.

Quiet Boot - determines the type of boot in a laptop. There are two options:

Enable - quiet. That is, information about the status of the device will not be displayed on the screen. The only exception is the manufacturer's logo.

Disable - the screen shows all the complete information about the state of the device. It occurs before the main operating system is loaded.

F12 Boot Menu - if you enable this option, then before loading the operating system, the user will be prompted to select a device from which to start loading.

Network Boot - literal translation - "network boot". This option is usually disabled and should not be enabled. Only in rare cases does it speed up system boot. In other situations, it may be necessary only if the laptop is connected to a network with a raised TFTP server. This is a server that allows you to download the laptop system kernel through the network.

Power On Display is the Acer laptop screen control. It contains two values: Auto and Both. Here you need to look at the situation. If an external monitor is connected to the laptop, then you need to decide: turn off the built-in screen and allow the picture to be displayed through the connected display, or leave two screens to work.

D2D Recovery is a feature that allows you to activate System Boot Recovery. D2D Recovery only makes sense if you use the additional Acer eRecovery Management utility. In other cases, it is not needed. This function allows you to write data to a hidden partition in the laptop system.

These settings are basic in an Acer laptop, but you can also install some add-ons. It is important to remember that it is highly undesirable to use non-original BIOS firmware, as they can cause a number of complications.

This section does not have much effect on the operation of the laptop. It provides the ability to set passwords.

Supervisor password is a master password (to enter BIOS and to the hard drive).

This section allows you to create a queue of requests to the laptop to install the operating system.

For example, if the following order is specified:

IDE CDROM
Flash drive

It is necessary to contact the BIOS only for those who understand well what they are doing. Since any wrong or thoughtless decision can even lead to mechanical failure.

So, there is a need to install Windows 7 or Windows 8 on an Acer Aspire ES1-511 laptop from a USB flash drive. We need to configure the BIOS on our laptop.

We turn on the laptop and press the F2 key to enter the BIOS. After clicking, we will see the Acer logo, and then we get, in fact, into the BIOS.

Immediately pay attention to the fact that the flash drive, with which we will then install the operating system, must be placed in the black USB connector of the laptop.

Go to the "Boot" menu tab.

In this window, go to the first line - "Boot Mode" with the up / down cursor keys ("?" and "?").

By default, "UEFI" is active. Select this line with the Enter key. A new small window will appear.

In the small window that appears, select the "Legacy" value. The computer may ask you about something a couple of times, we press Enter all the time.

After that, go to the "Exit" menu tab.

We have the first line "Exit Saving Changes" active. Press the Enter key. The computer will ask us about the need to save the changes and then exit.

We make sure that after the first press of the Enter key, the Yes value is active in the window that appears. We confirm our exit and save the changes by pressing the Enter key again.

The laptop should restart. At the end of the reboot, press the F2 key.

We are back in the BIOS.

We pass to the tab “Boot” already familiar to us. We see in the window that we already have the download sequence available. That is, where in turn the computer will look for our operating system to boot.

We find and use the cursor keys to go to our flash drive. The title should look something like this. USB HDD: model of our flash drive". In the picture, the name of our flash drive is Generic Flash Disc.

Go to the "Exit" menu tab. Press the Enter key. The computer in a new window will ask us about the need to save the changes made. We make sure that Yes is active and press Enter.

For many people, computers have taken an important place in their lives and are successfully used at work or during leisure. But in order for the computer to work quickly and without failures, it is necessary Make the correct settings in the program responsible for the operation of the equipment - BIOS Setup.

This program is responsible for such parameters: setting the date, selecting boot devices (CD, HDD, Flash-Drive), processor operation and other parameters, which will be discussed below. With the right settings, you can increase PC performance by an order of magnitude, but incorrect BIOS settings can lead to numerous system failures. At the same time, the prices for repairing laptops at home are very significant today.

In every computer BIOS setup has parameters set "by default" by the factory, but they are not always optimal, which means they do not give the maximum return of the system. And if the performance of a PC can be increased by replacing the hardware (without interfering with the BIOS), then in the case of a laptop, things are more complicated. It is worth noting that you only need to change the BIOS settings if you clearly understand what you are doing. So now we'll take a look at what it looks like Laptop BIOS setup - in pictures and with a description of the main settings. For the review, we will consider the Bios Setup of an Acer laptop.

In outline, Laptop BIOS setup consists of the following items:

information– information about devices and BIOS settings
Main- the main menu of the Bios Setup installation, containing the settings for managing laptop equipment
security- setting passwords for entering Bios Setup
Boot– selection of device priority for system boot.
exit– Exit and save BIOS settings

As for the first point, I think everything is clear here. We look at whether the time is set correctly, what devices are installed, the temperature of the processor.

With the second paragraph, it is much more difficult, so let's consider how this paragraph is carried out BIOS setup - in pictures and we will try to describe each item in more detail, since this menu is the most important for our system.

In this section, the first paragraphs ACER BIOS settings are date and time settings: System Time, System Date.

ParameterTotalMemory(also, depending on the BIOS version of the acer laptop, you can find Extended Memory, System memory) - shows the amount of system memory. It cannot be changed - it is for information only.

videoMemory- the size of the memory integrated into the motherboard, video cards. In our example, the video memory size is 128MB. Therefore, the following parameters are available to us: 64MB, 128MB and MaxDVMT (dynamic allocation of video memory within 128 MB.)

QuietBoot- This option allows you to select the type of download. The “Enable” value turns on the so-called silent boot mode - until the system boots, no information is displayed on the screen (with the possible exception of the manufacturer's logo). If you disable this area (disable), the screen will display all the information and test results carried out by the system before loading the OS.

Power On Display– has two values: Both and Auto. This item controls the Acer laptop screen. Depending on whether an external monitor is connected to the laptop, it will be determined: do not turn on the built-in screen or allow two screens to work together.

networkBoot- if literally, then this is downloading over the network. In most cases, it is best to disable this option (in particular cases, the system boot is accelerated). Basically, this option is needed in cases where your laptop is connected to a network with a raised TFTP server (a server that allows you to boot the system kernel over the network).

F12 Boot Menu- If you activate this item, before the system boots, a selection of devices from which you can boot your OS will appear.

D2D Recovery– activation of the system boot recovery function. Data is written to a hidden system partition. This function, in my opinion, is not very effective, and if you do not plan to use the Acer eRecovery Management utility, this function can be turned off.

Very rarely, but users need to enter the BIOS, for example, to change the order of boot devices when reinstalling the operating system, to disable unused components and deep self-test, or when overclocking the computer.

For the previous generation of Acer computers and laptops, after power-on, the subsystem self-test process (power-on self-test) starts. You can enter the BIOS only at this stage. While the monitor screen displays a graphic splash screen (Splash Screen) of the motherboard manufacturer or the results of self-test in text form, press the key a couple of times "Delete". A hint about which key or combination of keys to press is present on the start screen. As a rule, for Acer computers this is Delete, and for laptops from this manufacturer it is F2. If pressing the indicated keys fails to enter the BIOS, we study the instructions for the motherboard or laptop. It is possible that Acer has chosen a different combination for this model, or the device is equipped with a new software interface. In any case, attempts to enter the BIOS should be made after the indicators on the keyboard blink or light up, but before the operating system starts loading.

Instead of the Basic input / output system, new models of laptops and PCs can use the successor to replace the BIOS - the Unified Extensible Firmware Interface (UEFI). This interface differs significantly from its predecessor, including the loading time, which is no more than a few hundred milliseconds. In such conditions, it is very difficult to “catch” the moment to press the desired key. Fortunately, Windows 8 provides an alternative UEFI login mechanism. Press the key combination Windows + "C" and call the side menu.

Then successively press "Parameters" And "Changing computer settings".

Depending on the installed version of Windows, then click "Renewal and Recovery" or "General" and in the item Special boot options button "Reboot Now".

The computer restarts in a special mode, resulting in the Choose an option or Choose an action screen. Click here "Diagnostics".

In the menu that appears on the Diagnostics screen, select the item "Extra options".

If the UEFI Firmware Settings item is present in the next menu, it means that the computer is equipped with a new interface and can be restarted with automatic entry into its graphical shell. To do this, click on the appropriate button.

We agree with the proposal to restart the computer and after a short wait we get into the UEFI graphical menu.

A special Windows restart mode (to display the Select Action screen) can also be invoked through the Run window. To do this, press the key combination Windows + "R", enter the command in the window field shutdown.exe /r /o /f /t00 and click the button "OK".

As a rule, there are no problems with entering the BIOS. The main thing is to press the hot key in time or correctly perform a special reboot in Windows 8 and higher.

Instruction

Anyone who has launched the BIOS control panel on any desktop PC is already accustomed to frequently pressing the Del button to launch the BIOS. This is due to the fact that the vast majority of motherboards have the same supplier of chips for the basic input-output system (“Basic Input-Output System” - BIOS). With laptops, the situation is somewhat different - for different manufacturers, the BIOS launch key may differ.

Look carefully at the bottom of the screen when you turn on the laptop. Either at the left or at the bottom right of the screen, an inscription like “Press F2 to enter setup” briefly appears. Perhaps on your laptop the inscription will be slightly different, but the most important thing is to remember the key indicated in this line. It is this key that plays the role of the “Delete” button when starting a regular computer.

Restart the laptop if you didn’t have time to press the key in time and immediately after the boot starts, press the previously indicated key several times (many, in order not to be mistaken, use the multiple-press technique until the BIOS screen appears).

Also, the required button can be found in the manual for using the motherboard installed on your laptop. In the manual (often referred to as "manuals"), look for the "Bios Features" section. It describes step by step not only the process of calling the BIOS screen, but also recommendations for setting up your laptop, as well as a description of all the items contained there.

Download the manual for using the motherboard from the official website of your laptop manufacturer in case the paper version of the manual was lost for one reason or another.

Often, PC users have problems setting up Bios to boot from disk. This function is needed not only to start installing Windows, but also to diagnose the operating system with various utilities.

Instruction

First you need to enter the BIOS - to do this, restart your computer and as soon as the device check starts and the letters appear on a black screen, press the Delete key. For new motherboards and laptops, you can also use the F2 key. Navigation in the Bios menu is done with arrows. Esc is used to cancel any action, Ctrl+Alt+Delete is used to reload, and Enter is used to save changes.

Select Advanced Bios Features and press the Enter key. In the menu that opens, find the items First Boot Device, Second Boot Device (depending on the motherboard and Bios version, the names may vary slightly). These options are responsible for the order of devices from which the operating system will be loaded. By default, Floppy will be selected in the first item, Hard Disk in the second, and Cd-Rom in the third. Highlight First Boot Device, press the Enter key, use the arrow to select the Cd-Rom boot option and press Enter again. Next, select Second Boot Device and set it to Hard Disk. After that, exit to the Bios main menu, select Save and Exit Setup and confirm saving the changes. Your operating system will now boot from the disk.

After completing the necessary steps for installing Windows or diagnosing the system, return the previous boot order, otherwise the boot from disk procedure will be performed again and again. To do this, enter Bios again, open the Advanced Bios Features menu. Then select First Boot Device, set it to Hard Disk. Set Second Boot Device to Cd-Rom.

BIOS - what is it and why is it needed

The abbreviation stands for "Basic Input Output System" or "Basic Input-Output System". It starts when the device is turned on and is a black screen with white letters and numbers. When the PC starts, it tests the subsystems, after which it transfers control to the OS loader and the operating system itself.

It is worth saying that modern laptop models from hp, lenovo, asus, acer, samsung, sony vaio are not equipped with BIOS, but with its more advanced version - UEFI. There is no difference between the data system in terms of access. The only thing is that UEFI is a more modern version of software that simply replaces the outdated BIOS, performing its functions.

Is it worth going into the settings?

If you are an inexperienced user, then you should stay away from him and do not climb unnecessarily. This can be explained by the fact that changing the parameters without understanding your actions can disable the computer and it will simply stop loading. If you do not understand what this or that function is responsible for, just do not touch it, otherwise your actions may end badly not only for the laptop, but also for your wallet.

If you, at least a little, but understand a PC and have an idea of \u200b\u200bwhat a BIOS is and how to work with it, then if necessary, you can open the BIOS on your laptop yourself and do what you need. We will talk further about how to do this.

BIOS entry

In order to enter the BIOS on a laptop, regardless of the type of Windows XP, 7, 8 or 10 installed, hot keys or combinations of them are used. And they depend not only on the manufacturer of the laptop, but also on the motherboard. That is why you should remember the key combination designed specifically for your PC, because at the most inopportune moment, there may be no instructions or other device with Internet access at hand.

Another difficulty that you may encounter when you need to call the BIOS is fast booting of the laptop. While you read the inscriptions, and decide which button you still need to press, the OS will start loading. In order not to get into such a situation, you must either know the hotkeys that activate bios on your device, or use the system boot pause function (called by pressing the Pause key). However, not all laptops support this option.

Keys to launch

Let's look at the main key combinations that are often used to get into it:

"F2" is the most common key to enter the BIOS. It is designed for laptops from Lenovo, Acer, Asus, Panasonic, Fujitsu-Siemens, Sony, Samsung, Dell, and Toshiba.
"ESC" is used like "F2" in some Toshiba models.
"F10" is for HP and Dell laptops.
"F1" is sometimes used in Lenovo devices.

Continuation of the list of keys for some models:
