Entering the BIOS on a laptop. How to restore BIOS on any laptop? Step-by-step instruction
Personal Computer, tablet, laptop - many gadgets are used daily by people for work, watching TV series, surfing the Internet and other purposes. From time to time the need arises to reinstall the system, change the PC settings, and the question of how to enter the BIOS in order to make the necessary manipulations becomes relevant. Often on home page there is a hint to enter, but such a simple task sometimes causes difficulties, because for different types bios, brands of laptops and systems on the computer must be pressed different keys or combinations thereof.
Why you might need to enter BIOS
For many, entering the BIOS is associated with solving one problem - reinstalling, changing the operating system. In fact, with its help it is possible to solve several important issues to improve the functioning of a computer or laptop, find out some data about its operation. At bios help you can perform the following manipulations:
- Check the functionality of the computer. It is possible to obtain data about the state of the PC, for example, processor temperature.
- Tune system time and date. Performing this action is necessary every time after resetting the BIOS settings, since the date/time configurations change along with them.
- Connect or disable individual PC functions.
- Change the disk from which the OS will boot. After opening the BIOS, the user can independently select and designate the location from which the operating system will boot. It can be hard disks, CD, DVD media or flash drive. You can specify several drive options from which the OS can be started. For example, if for some reason the download did not occur from the first media, it will be carried out from the second.
- Connect or disconnect components integrated into the PC. For example, there may be a shutdown sound card or video cards.
- Overclock your computer. To improve the operation of the device, increase its performance or speed, or speed up the processor, non-standard frequency and voltage parameters can be set.
- Reinstall the operating system, identify and fix problems with its operation.
- Check the PC contents and normal functioning, initialize all its components.
- Fix the problem if the Android-based tablet freezes or the gadget does not see connected devices.
BIOS and its main types
Many people have heard about bios more than once, they even roughly understand why it is needed, but what it is, how you can enter the BIOS, what types there are, remains not entirely clear. Before considering questions about logging into the system and the intricacies of working with it, you need to understand the meaning of this word. BIOS is a basic input/output system that is responsible for loading the OS, the operation of individual PC components, and interaction with hardware.
Essentially, BIOS is a large number of microprograms that are written to the board. There are types of systems in which the main differences are the interface and the login method:
- Award (Phoenix-Award). This BIOS has work area- blue window.
- AMI ( American Megatrends).
- Phoenix.
- DTK (Dalatech Enterprises CO).
- UEFI.
- ALR (Advanced Logic Research).
How to enter the BIOS of a laptop or computer
To enter the BIOS, you must press a certain button on the keyboard or a combination of them. Which key will help launch bios depends on the type of system and brand of laptop. Often when the PC boots, information about the computer appears on the screen and a hint appears on what to click. As a rule, such a message is located in the middle of the screen or at the bottom and looks like this: “Press Del to enter Setup”; instead of delete, another key or combination may appear. You should press the button immediately after turning on the device.
How to enter the BIOS correctly:
- For Award, use the Del (Delete) or Ctr+Alt+Esc key.
- For AMI – F2, Delete.
- ALR – F2 or Ctr+Alt+Esc.
- Phoenix - Ctr+Alt+Esc, Ctr+Alt+S, Ctr+Alt+Ins.
- AMD - F1.
- DTK – Escape (Esc).
Other button combinations can be used:
- Ctrl+Del+Alt
- Ins+Ctrl
- Ctrl+Alt
- Ctrl+Alt+Enter
Login features on laptops of different brands
Depending on the laptop model and brand, the methods for entering the BIOS may vary. Often, a hint is displayed on the splash screen every time the device boots, but sometimes, in order to find the required button or combination, it is worth spending time on “trial and error” or searching for information on the manufacturer’s official website or programmer forums. In addition to the device model, the type of system and its version play an important role.
How to correctly enter the BIOS on different laptops:
- Lenovo (Lenovo) - to enter the BIOS, press and hold the “ThikVantage” button until the menu or F12 appears.
- Toshiba (Toshiba) Portege, Satellite, Tecra – press Escape, Tecra with Phoenix BIOS– F1.
- Acer – F2, F1, Ctr+Alt+Esc.
- Acer Aspire – F2, Del.
- Asus (Asus) – to enter Setup, press the F2 button.
- Sony – F2, F3, F1 for Vaio – F2.
- Dell – F3 or F1.
- Hewlett-Parkard (HP Pavilion, Tablet) – F1.
- Samsung (Samsung) - F2, F12, F8, Del, Esc.
- eMachine - Delete.
- MSI – F1, F2, F12, Delete.
- Compaq - F10.
If the computer requires a password when entering the BIOS
Often a password is placed on the BIOS; it can be set in order to save settings or protect a laptop or all-in-one PC from changes to the system by other users. But memory is a tricky thing, and it often happens that secret code forgotten, but logging in is simply necessary. After several unsuccessful attempts, the screen goes blank and the user begins to panic. But everything is not so scary, there are several options for how to enter the BIOS system without a password:
- Find a “Clear CMOS” jumper on the motherboard of your laptop or computer, which will clear the memory, including the password. To find the location of the key, you should first read the instructions and diagram motherboard.
- Remove the CMOS battery for at least twelve hours, preferably for a day. Then reconnect it and start the system. The disadvantage of this option is the long waiting time.
- Introduction engineering password For motherboard instead of bios code. The disadvantage of this method is that it cannot be used for older BIOS versions.
To avoid such problems in the future:
- Set a password to enter the BIOS in exceptional cases.
- Write down the password in places where it will be securely stored and, if necessary, can be quickly found.
What to do if you can’t enter the BIOS
Often there are problems when you can’t log into the system. This can be caused by several reasons:
- The wrong key or combination of keys was selected for entry. Double-check your laptop model and version. It is necessary to try other options and combinations.
- OS loading started before pressing required key. It's worth pressing it faster.
- To solve some problems, you need to clear the memory, reset it to factory settings using the “Clear CMOS” switch.

The latest laptop models allow you to fix a number of errors that arise on your own, so advanced users often ask the question: how to open bios on laptop to solve the problem without calling a specialist.
How to open the BIOS on my laptop a question of interest to users who have a clear understanding of .
There can be many situations that require urgent login, but the most common are setting up certain modes: or sleep.
Before we move on to the discussion , you need to know what the system is.
What is a BIOS system?
The BIOS system is a collection of programs located.
Until the system is fully loaded, each advanced user can perform many manipulations, changing the settings according to their own needs.
An example is POST.
The main function is a high-quality check of all systems for errors in operation. If malfunctions are detected, the BIOS reports this.
Besides, this mode helps eliminate errors and improve normal work laptop.
However, these are not the only possibilities BIOS mode which they can.
When should you open the BIOS?
Experienced PC users are interested in , under the following circumstances:
1 Activate/disable specific components found on the laptop. Exist individual components in a laptop, which can be enabled, or vice versa, disabled in the BIOS
2 Replacing the video card. Technologies do not rest on the progress achieved, so often new laptop models are equipped with two video cards at once. As a rule, there is an integrated and built-in card. In the BIOS you can change the settings and use only one of them
3 Activation certain regimes device operation. Disable or activate
4 Adjusting the time in the system. As a rule, such a need arises only if all settings in the BIOS system have been previously reset
5 Monitoring computer operation and system status. The BIOS system displays indicators of components that ensure full operation of the laptop, as well as monitoring the temperature inside the device
6 Reset existing settings in the BIOS system. As a rule, such a need arises if the laptop begins to work incorrectly. To avoid wasting a lot of time troubleshooting, you can
7 Changing other parameters.
Now it's time to move directly to the main issue.
How to start
On many laptop models, after pressing the corresponding button, a notification appears, how to proceed further:
Important! After Windows starts loading, using any combinations to get into BIOS system will turn out to be useless.
To try again, wait until it boots completely, reboot the laptop again and repeat the prescribed procedure.
Unfortunately, some laptop models do not have hints on which keys to press.
Then you will have to select combinations in independently.
It's better to try first universal options to enter the BIOS.
Various manufacturers can lay various, in addition to different versions Windows keys can also change.
If the laptop has version up to seventh inclusive, then you can consider the following options:
To make the task much easier, it is recommended to pay attention to the following pictures: where the location of the corresponding keys is shown:
How to enter the BIOS if version 8 is installed
Unlike versions below the seventh, it is significantly different.
So, for example, pressing special combination to full Windows boot will not bring the desired result, since many manufacturers have decided to increase the loading speed of the operating system in this way.
Restoring settings
It is worth noting that there is great amount features that can change how your laptop performs.
If the user has not previously had experience in this area, then changing the settings independently may lead to incorrect operation device, or completely damage it.
If the computer stops performing a number of universal tasks, it is recommended to reset the system settings to the standard view.
There are three most common methods:
- Using Setup. In the case when the computer is still functioning and it is possible to restart the laptop, then you can use Setup. First, log in to the system and find the appropriate item, as it shown on the picture:
It is worth noting that depending on , the name of the function on English language may differ slightly, but is quite easy to recognize intuitively.
Most often you can find “Load Setup Default”.
- Using a battery. If the user is afraid of the first option, or it is impossible to restart the laptop, then you can simply remove the battery from the laptop. In fact, this method is optimal and safe. As a rule, the battery disconnects for a couple of minutes. This procedure clears the CMOS memory.
As for the location of the battery, manufacturers place it in a variety of places.
As an example, the explanation in the document might look like this:
For fine tuning There is a so-called BIOS on your computer. It controls how the computer turns on, allows you to change some of its settings before the operating system boots, and selects which disk to boot from. Those. When the computer turns on, it immediately looks at its settings in the BIOS.
In this article I will show you how to enter BIOS on different computers and laptops. There are many of them, but the logic is approximately the same. For better understanding There will be several videos where I show everything using real examples.
General understanding of BIOS entry
I made several videos for you from different computers. If you watch the whole video, but it turns out a little wrong on your computer or laptop, then don’t despair. Using the information received, you can easily figure out how to enter the BIOS. There are three main types of BIOS: Award (Phoenix-Award), AMI (American Megatrends) and UEFI. Award bioses mostly come with blue windows, AMIs with gray-blue ones, and UEFIs with beautiful graphical interface.
In order to enter the BIOS, you need to press one button or, in rare cases, a combination of buttons when the computer starts. The whole question is WHEN and WHAT to press. Please note that as soon as the computer turns on, a certain icon is displayed on a black background and at the bottom or middle of the screen you are asked to press one or more keys. One of them is entering the BIOS.
For Award this is usually Delete key(Del), and for AMI - the F2 or F10 key. At the bottom of the screen it will say something like this “Press Del to enter Setup”. Setup is the same as BIOS. There are also buttons: F1, F3, F10 ( Hewlett Packard), F12, Esc and combinations: “Ctrl+Alt+Esc”, “Ctrl+Alt+Ins”.
On IBM laptops Lenovo Thinkpad you have to press and hold blue key“ThikVantage” until the menu appears. And on some Toshiba laptops press “Esc” and then “F1”.
You must press quickly and several times (just in case), otherwise the computer will continue to boot and will not enter SETUP. If you don’t have time, just restart your computer using the “Reset” button on system unit or using the key combination “Ctrl+Alt+Del”. And if you don’t have time to read the information, then click on the “Pause” button.
If, when you turn on the computer, the full screen is screen saver, and nothing is visible behind it, then try pressing the “ESC” key to hide the splash screen and read the information from the screen on how to enter the BIOS. Also, which button to press can be found in the manual for the motherboard of your computer or laptop. It also happens that, then study these articles.
How to enter BIOS on different computers and laptops
You can see which BIOS you are using when you turn on the computer, when it appears on the screen general information, but in principle this does not matter, the main thing is to see which button needs to be pressed:
The example shows that the computer has Award BIOS version 6.00PG, and at the bottom you are asked to press the “Del” and “F9” buttons. IN in this case To enter SETUP, use the “Del” button, and “F9” brings up a menu for selecting the boot device. The BIOS itself may look like this:
Watch the video on how to log in BIOS Award, and also set boot device:
And here is another variety of “Award”
No information about the version is written, but it is clear that you need to click in order to go there. Watch a video with this example:
But in this picture you can see that the computer is controlled by the “AMI” BIOS and the usual “Delete” key is used to enter:
But here is a completely different option, which uses the “F2” key
And the BIOS “AMI” itself in all cases looks something like this:
Watch the video on how to enter BIOS on a laptop with “AMI”, using an example ASUS Eee PC:
In fact, the procedure for logging into SETUP on computers and laptops is no different, because everything depends only on the version of the BIOS used.
Another option is how to enter the BIOS on Lenovo laptop. There are no hints at all, you just need to know that during the splash screen you need to press “F2”
On models Lenovo series G500 you need to press the OneKey Recovery key when the laptop is turned off, and on some models Fn+F2 (or F12) works.
IN Lately More and more often you can find computers with UEFI. But this is not even a BIOS in the usual sense, but a small operating system that is compatible with the BIOS and performs its functions. It can be with a graphical interface, or it can be in regular text mode. Entering there is also not difficult, for example using the “Del” button
In general, I think you understand the logic of entering different BIOSes, because there is nothing complicated here. In 90% of cases, SETUP includes to . Well, if for some reason you cannot do this, then refer to the instructions for your motherboard or search the Internet by the name of the computer or laptop model.
My BIOS is asking for a password, how do I reset it?
If someone set a password before you, then when entering the BIOS you will need to enter this same password. On laptops, the password reset process is quite complicated. trivial task and for each specific model need to look for information. But with computers everything is much simpler, so how to reset BIOS password possible using special jumper, which is found on almost every motherboard. This jumper is called “Clear CMOS” and you can find it next to the battery:
There are three contacts on the board, two of which have a jumper. Usually it’s enough just to move it to the other two contacts for 10 seconds, and then back. Before doing this, you need to unplug the power cable from the computer. If the password is not reset or there is no jumper at all, then additionally remove the battery from the motherboard for a few minutes:
The BIOS password should be reset, as well as all its settings. Please take this into account, because... settings can significantly affect the overall .
These are the pies, ask in the comments if anything is unclear.
BIOS or BIOS is an English abbreviation for “Basic Input/Output System”. In Russian, simplest system input-output information. To put it simply, BIOS is a program that introduces the software and hardware components of a computer. BIOS allows software such as Windows to work with the physical devices installed in the computer.

How to open the BOOT menu
In more or less modern devices It is not only possible to change the boot device in the BIOS, but also to start once with desired device. I wrote about this in an article about
Nowadays, laptop manufacturers are doing everything possible to ensure that their owners can fix the problem as easily and quickly as possible, without leaving the operating system. But it’s worth clarifying that laptops are designed on the same principles as desktop PCs, and in some cases it’s impossible to cope without getting into the BIOS settings.
For example, if you decide to reinstall the OS or an error occurs while overclocking a component. How can you enter the BIOS on a laptop in this case? This is quite simple to do, but let's talk about everything in order.
BIOS - what is it and why is it needed?
The abbreviation stands for "Basic Input Output System" or " Basic System Input-Output". It starts when you turn on the device and is a black screen on which letters and numbers are displayed white. When the PC starts, it tests the subsystems, after which it transfers control to the OS bootloader and the OS itself. operating system.
It's worth saying that modern models laptops from hp, lenovo, asus, acer, samsung, sony vaio are equipped not with BIOS, but with its more advanced version - UEFI. There is no difference between the data systems in terms of access. The only thing is that UEFI is more modern version software, which simply replaces outdated BIOS, performing its functions.
Is it worth getting into the settings?
If you are an inexperienced user, then you should stay away from it and not interfere unnecessarily. This can be explained by the fact that changing parameters without understanding your actions can damage the computer and it will simply stop booting. If you don’t understand what a particular function does, just don’t touch it, otherwise your actions may end badly not only for the laptop, but also for your wallet.
If you are at least a little knowledgeable about PCs and have an idea of what 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.
Login to BIOS
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 thereof are used. And they depend not only on the laptop manufacturer, but also on the motherboard. This is why you should remember the key combination intended specifically for your PC, because in the most inopportune moment You may not have instructions or another device with Internet access at hand.
Another difficulty you may encounter when you need to call up the BIOS is fast loading laptop. While you are reading the inscriptions and deciding which button you still need to press, the OS will begin to load. To avoid getting into this situation, you need to either know the hotkeys that activate the bios on your device, or use the function of pausing the system boot (called by pressing the Pause key). However, not all laptops support this option.
Keys to start
Let's look at the basic key combinations that are often used to get into it:
- "F2" is the most common key to enter the BIOS. It is intended 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 intended for HP and Dell laptops.
- "F1" is sometimes used in Lenovo devices.
Continuation of the list of keys for some models:
Now you know how to enable the BIOS yourself. You just need to remember a few important rules that will definitely help you with this:
