How to open the BIOS on a laptop - all possible methods. Is there a BIOS (Recovery-Mode) on Android and how to enter it How to open bios on a Microsoft phone

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.

In addition, this mode helps eliminate errors and establish normal work laptop.

However, these are not the only possibilities BIOS mode which they can.

When do you need to open the BIOS?

Experienced PC users are interested in , under the following circumstances:

1 Activate/disable specific components found on the laptop. There are individual components in the laptop that can be enabled or 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

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. So as not to waste a large number of time to identify the malfunction, 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! Once Windows starts loading, using any combinations to get into the BIOS will 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 on your own.

It's better to try first universal options to enter the BIOS.

Different manufacturers may provide different different versions Windows keys can also change.

If the laptop has version up to and including the seventh version installed, 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 in this way operating system.

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 can lead to incorrect operation of the 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 corresponding 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:

How do I exit the BIOS?

The BIOS system on any PC device is an important element.

Regardless of the fact that there may be some differences, the design of the system in any device has similar features.

To exit this mode upon completion of work, It is recommended to use the following instructions:

  • Turn on and restart the computer by pressing the keys discussed above
  • If the first attempt is unsuccessful, then wait until Windows boots completely and repeat the procedure
  • As a rule, to organize an exit from the BIOS system, you just need to press the F button. Then a tab appears where it will be written “EXIT”. Select and press enter.

It is worth noting that a variety of troubles may occur along the way.

The most popular is password reset. In this case, there are two solutions to the problem that has arisen.

The first option is the simplest, since you must enter a password (if the user remembers it).

Turn on and reboot the laptop and hold down the Del button. Next, a window should appear asking for a password.

Open Set Supervisor Password and enter the password. We do not fill in the place where you need to enter a new code.

In some systems it is impossible to completely remove this function, but it is possible to disable its checking.

Select Power On Password and enable Disabled.

Once the steps have been completed, you must begin disassembling the device.

Located on the motherboard small device, responsible for the functioning of the BIOS.

Using a screwdriver, close the ends.

In this case, all settings will be automatically reset and the password will be automatically deleted.

BIOS System Features

Since the BIOS system is the initial authority for starting the device, it provides many opportunities for any user, including changing the standard settings for the laptop to expand its capabilities.

The main functions include:

  • When the power is turned on, the system can independently automatic mode carry out diagnostic measures
  • Initializing devices responsible for input and output
  • Operates, which deals with the process of loading RAM
  • Engages in high-quality information processing and also ensures storage of programs responsible for computer maintenance
  • Using the BIOS you can do self-configuration in such a way as to achieve the appropriate configuration and fulfill all the requirements stated by the user
  • Participates in the process of computer interaction with, and also supports loading the appropriate drivers.

The BIOS system provides many options for each user.

However, it is important to note that if you have little experience working with BIOS, it is not recommended to change the installed configurations on your own, since this can lead to damage to the device, which means paying double the labor of a specialist.

Attention! Also, do not forget that different ones can include their own developed algorithms for working with the device, so changing some settings can lead to “braking” of the system and the inability to continue normal operation on the laptop.

Then such actions will help correct the error or update the system version, if necessary.

To perform certain tasks or fine tuning To customize your computer, you need to interact not only with the operating system components, but also with the BIOS settings.

In order to work in BIOS, it makes no difference what OS is on your computer. You can open the BIOS on Windows 7 in the same way as on Windows XP or any other operating system.

Finding the access key in BIOS

The main thing that determines the choice of key to enter the BIOS is the type and release date of the motherboard located in system unit. To find out these parameters, you can refer to the documentation for your computer, or find the necessary data in the computer characteristics recorded in the system ("Start" -> "Control Panel" -> "System" -> "Hardware" -> "Device Manager" ), and you can also search for them on the Internet by motherboard model or laptop model (if you have a laptop).

That is, just look for: “BIOS entry key” + brand of laptop (or motherboard). Or, if nothing was found, then: “BIOS enter key” + brand of laptop or motherboard (on the English-language Internet there is probably a better chance of finding the right key). But there is a simpler option - try to find the right keys at random.

When the computer turns on, it conducts a kind of roll call between devices: whether there is a processor, which one is installed RAM, is there a system and what video card. True, all this happens in a matter of moments and it is rare that you have time to read even the first lines of the message displayed on the screen from this “roll call”. Although usually these lines indicate the current access key in the BIOS (most often this is the “Del” key).

Enter BIOS

In addition, modern monitors prefer to show their brand when booting, rather than messages from the BIOS, and only after that the operating system boot loader becomes the full owner of the situation and begins to execute your commands.

Therefore, in order to open the BIOS, before loading Windows 7, you should press the necessary keys exactly in that short moment while all computer components are being initialized (the first 3-5 seconds after turning on). Perhaps this will be signaled by a sign saying that to enter the BIOS you need to press one or another button, for example “Press F2 to enter Setup”. You need to do this quickly - only a few seconds are allotted.

The buttons themselves, with which you can open on various motherboards: "Del", "F1", "F2", "F10", "Esc", "Ctrl+Alt". One of them (or a combination of keys) should be pressed as many times as possible within the allotted period for the system to respond 100%.

Most often, immediately after turning on the computer, you need to “click” the “Delete” button (or “Del” on some keyboards) for 3-5 seconds. Moreover, if you have two such buttons on your keyboard, then you need to press the one that is closer to the “arrows” (that is, next to Enter).

Nuances of laptops

Here it is worth noting the following fact - if you suddenly are the proud owner of a laptop or netbook, then be prepared for the fact that the initialization window may not appear.

The fact is that this procedure is carried out by the system only after the computer is turned off. Have more mobile versions personal computer Typically this process replaces hibernation or sleep mode. This means that laptops and nettops do not turn off in the usual sense of the word, but suspend their activities. To completely turn off your device, do not reboot it, but unplug it from the network or even remove and insert the battery.

BIOS – software, which specifies all the low-level settings for your computer. And those who have just recently switched from a PC to a tablet often wonder how to enter the BIOS on a tablet.

I would like to say right away that there is no BIOS on tablet computers, except for those that run on the Windows operating system. The rest only have modes that simulate the operation of this software. For example, for Android it is recovery, for iOS it is DFU.

Where is the BIOS located?

After calling the main menu on the gadget display, you must do the following to find how to get into the system software:
  1. Go to "Settings".
  2. At the bottom there will be a line “Change parameters”, you need to click on it.
  3. A menu will pop up on the left, where you only need the bottom line “Update and Recovery”, click on it.
  4. Now you will see a small list of functions, select the “Recovery” section.
  5. On the right, click on “Reboot Now”.
  6. The tablet will begin to reboot, after which the “Select Action” menu will appear, and the display color will turn blue.
  7. Here select “Diagnostics”, and in it – “Advanced parameters”.
  8. Once several icons with different system functions appear, select “UEFI Firmware Settings.”
  9. Click Reboot.
  10. When the device turns on again, you will automatically find yourself in the BIOS.

How to enter BIOS via keys


You can also open the system software using the keys located on the case tablet computer with Windows OS. For this:
  • Press the volume down and power buttons on the device.
  • Hold them for four to five seconds.
  • Once you enter the BIOS, the keys can be released.
This way you can start working with the tablet computer system.

With the release of the new operating room Windows systems 8 there have been many changes both in the system itself and in the process of accessing the BIOS. Now, to load the BIOS, you no longer have to press a specific key during the boot process. The BIOS access option is now located in the Windows boot menu.

Previously, computers would inform users with a message "Press F2 to enter setup mode" at the beginning of the boot process and the action would open Computer BIOS. But some PCs Windows based 8 equipped solid state drives, load so quickly that the user does not have time to press a given key or key combination. This is not the only reason why the creators decided to change the procedure for accessing the BIOS. Now Hardware Windows 8 uses UEFI to replace the traditional BIOS in the same way as for Mac computers from Apple.

Computers designed for Windows 8 vs. older ones with Windows 8
It is worth paying attention to the fact that new way Login is only applicable on new computers with Windows 8 already installed, which uses UEFI. If you install Windows 8 on an old PC with BIOS, access to it will continue as before. Simply press a key during the boot process. Typically the F2 or Delete keys are used, but other options exist. It depends on the computer. If you find it difficult to select a key during the boot process, read your computer's user manual.

Accessing boot options
There are several options for how to access Windows 8 boot options. The easiest way is through new interface"PC Settings". To call it, simultaneously press WinKey+C, will appear side panel, then click Settings and select Change PC settings.

In the settings, select the “General” category and click “Restart now” (the button is located under the “Special boot options”). The computer will reboot and you will enter the boot menu Windows settings 8, where you will have access to the UEFI BIOS and can change other settings.

To reboot your PC directly to the boot menu, hold Shift while pressing the Restart button. This is the most quick way reboot to the boot menu.

For those who like to use command line, there is also a way. Run the "shutdown.exe" command to reboot the computer into the boot menu (Shutdown.exe /r /o).

Access to UEFI BIOS
Creation boot menu was necessary to integrate some of the most used options that caused users to use the BIOS. For example, if you want to boot your computer from USB, CD or DVD, then you need to click the required item marked desired device. If you are logged in to access your computer's UEFI BIOS, click the Troubeshoot button.

"Advanced Options" will appear on the screen. These are additional tools with a "UEFI Firmware Settings" option that directs a person directly to the computer's BIOS (in UEFI, which is designed to support a single EFI interface. In this case, the settings are equivalent to the traditional BIOS of computers).

If the "UEFI Firmware Settings" option is missing, it means that your PC does not use UEFI technology. Access the BIOS the traditional way. Even if Windows fails to boot, you won't be locked out of the BIOS because the boot screen options appear as soon as you turn on your computer.

Why are changes needed?
Some users have found the changes inconvenient because they cannot access the BIOS without booting into Windows. But, as practice has shown, they are simply necessary. The official website of Microsoft, which describes the advantages of Windows 8, describes in detail everything that happens with new system in this direction.

As stated above, there were cases when, with an increase in boot speed on some systems, too little time was allotted for pressing the desired key. Even the most best program, which emulates keystrokes, can only press one button once every 250 milliseconds. In this case, to access the BIOS you would have to hit the key with great speed, besides, you would need luck, and several reboots of the computer would not hurt.

Changes in the system have unified Windows 8 to some extent. So, now all computers will have the same way to access the BIOS. Before that, they used different key combinations at startup.

Naturally, Windows 8 has many controversial issues and decisions that users do not like. However, a real way to access the BIOS has been needed for a long time.

Advances in technology have made it possible to significantly increase the capacity of flash drives. During this time, CDs completely disappeared from our lives, even Microsoft began distributing Windows 10 on flash drives. But what to do if the BIOS does not see bootable USB flash drive, which contains the software you installed.

Causes and solutions

There are not so many reasons, they are almost all related to the BIOS settings.

Important! First, you should make sure that the flash drive is working. By connecting it to another computer or laptop, check if it is displayed.

Incorrect image entry

The installation flash drive is created using special programs, it’s not enough to just put the file on the drive, it needs to be written down correctly.

If you want to record Windows image 7, then use the proprietary Microsoft utility.

For others Windows versions and other programs, it is better to use UltraISO.


BIOS settings

What to do if the flash drive is written correctly, but loading from it does not occur? Most likely the problem is in the BIOS settings.

Device startup order

Advice! Connect the drive to the USB port before performing next steps. This will make it easier to detect.


Download mode

The second reason may be that the flash drive is not visible in Boot Menu due to boot mode mismatch. Most devices support two boot modes: Legacy and EFI. If the BIOS is set to Legacy mode, and the flash drive is written for EFI (or vice versa), then the system will not be able to recognize it.

The only thing you need to do in this case is to specify the desired mode through the Basic Input/Output System.


As a last resort, we recommend resetting BIOS settings. You can read how to do this in the article “Resetting the BIOS configuration on a home computer and laptop.”

USB port support

Sometimes situations happen when the PC does not see the flash drive through USB port 3.0 when trying to install a system from it. This is most likely due to the BIOS configuration. To solve the problem, just change the flash drive to USB 2.0.
