Exit to bios on a laptop. How to enter the BIOS on a laptop: from standard to exotic methods it’s not far...

Youtube

Currently on the market computer equipment presented great amount manufacturers. All of them produce equipment adapted for use on three software platforms: Windows, Mac and Linux. Despite the advantages of the last two, the generally accepted global standard is that the equipment is compatible with the operating system. Microsoft. But no matter how hard you try, sometimes a hardware conflict can occur: software may fail.

BIOS works regardless of the installed OS

To solve some problems, there is a BIOS mode that allows you to make a number of settings up to full inclusion computer. It is available on any PC running Windows 10 and other versions - it’s like air for it. The only inconvenience is that each manufacturer programs its own key combination to launch it. Let's look at how to enter the BIOS on a PC or laptop from different manufacturers.

What is BIOS for?

It's like this shell, recorded on motherboard, operating independently of the OS. It controls all built-in equipment immediately after power is supplied. Thanks to this, after a failure of Windows 10 or another version of ex. The BIOS also controls the connection additional devices and ensures their uninterrupted operation. Since all the code is written on the motherboard, it depends on it how to enter the BIOS.

Login to BIOS

Old motherboard models

Almost all models allow you to get into the BIOS by pressing Delete. There are also other options.

Older models of motherboards, which were created for computers running Windows XP or 7, do not start instantly, but display the manufacturer’s logo for a few seconds, and at the bottom of the screen they write which button to press to enter the settings. For example, users may see the phrase Press DEL to enter SETUP. This means that the login is performed by Delete key. Another button may be specified instead.

Therefore, if you have a computer or laptop that has old version BIOS, look carefully at what the system writes at startup. By the way, even if you are using Windows 8 or 10 on an old laptop, the BIOS remains unchanged, and you will log in this way. If you don’t have time to press a key because the screensaver quickly disappears, start pressing it many times until you enter this mode.

New motherboards

If your computer is newer and was originally designed to work in Windows 8 or 10, most likely the screensaver will not appear at all. In this case, you need to know for sure which button is right for you. Try Del right away, if it doesn’t let you in, then use the information below. Feel free to click until you get to the BIOS.

Possible key combinations

Depending on the motherboard manufacturer, the login keys may be as follows:

ALR - F2, Ctrl+Alt+Esc

Award - Del, Ctrl+Alt+Esc

Phoenix - Ctrl+Alt+Esc, Ctrl+Alt+S, Ctrl+Alt+Ins

You can find out the motherboard model through the AIDA64 program. Necessary information contained in the tab " Motherboard" If you can’t find out, then try all possible options until you succeed.

Laptops

Laptops are no different, but to get into the BIOS, you need to press the desired key or combination of keys. On a laptop, you do not need to look for the motherboard model, since the button differs depending on the company. On an older laptop, after turning it on, try waiting until the

Quite often, to fix some problems with the operating system or with connected devices, users have to turn to the primary BIOS input/output system, which stores information about all the “hardware” components that are present in the computer assembly. Almost all users of stationary terminals know how to launch the BIOS before starting the system. But not everyone understands exactly what functions are there, and what can be done even to eliminate operating system errors. The following is material that will help you understand the main aspects related to what it is in general and how the primary system is configured.

What is BIOS?

Let's start with the definition itself, leaving aside for now the question of how to launch the BIOS. The primary system stores all data about the present “hardware” devices connected both to the motherboard and as peripherals.

Actually, the question of how to run BIOS on Windows 7 or any other system can be considered completely incorrect. Yes, some users believe that the start of the primary system depends on installed version Windows. We must upset everyone at once! Whether you have Windows or Ubuntu, these operating systems are initially BIOS settings have only an indirect relationship, determined only by information about the hardware (and even then, not always).

What is UEFI?

Now, in solving the problem of how to run BIOS on Windows 7 or another system, let’s look at what it is a new version firmware called UEFI.

This system appeared relatively recently. The most important difference between the previously absolute standard BIOS system and the new UEFI is that the current system has a graphical interface that is different from the DOS-like BIOS, and allows not only more fine tuning parameters, but in some cases it is called even without restarting the operating system.

How to run BIOS on Windows 7?

But now let's specify the main question. If someone still doesn’t understand what operating system is installed on the computer, it doesn’t matter at all. The primary system can be booted even if it is missing or damaged.

On stationary terminals, the question of how to enter the BIOS on a computer that complies with the PC standard is solved quite simply. Many people have probably noticed that at the very beginning of the computer boot, after the basic information is displayed, the line “Press Del to run setup” or something like that appears at the bottom. It remains on the screen for about two to five seconds, and during this time you need to have time to press the designated key, after which you will enter the settings.

How to run BIOS on a laptop?

For laptops, manufacturers are increasingly coming up with workarounds for entry. How to open BIOS on laptops?

It all depends solely on the manufacturer. The most common keys are in the range from F2 to F12. You can often find combinations of them with the Fn key (double). Even less common are access sequences based on a triple combination, where Fn acts as the main button.

Finally, many laptop manufacturers, in order not to complicate life for users, install shortcut buttons on the keyboard panel. In this case, the question of how to start the BIOS can be solved quite simply (in some cases, even without rebooting the system).

Quite often you can find various kinds of menus that allow you to return the laptop to its original state through the primary system. For example, in Sony VAIO To do this, there is an ASSIGN button right on the keyboard panel, after pressing which you can get to the menu where you can access the BIOS. For models from Dell latest issues In general, there is a special menu for going to UEFI parameters.

Firmware update

We figured out how to open the BIOS. Now let's move on to one of the most pressing questions regarding firmware. What is it for? The fact is that computer hardware is becoming more and more advanced, and BIOS systems are not automatically updated, do not have time to keep track of the release of new devices and, ultimately, do not detect them when connected, as a result of which even Windows any version begins to install drivers that seem to be the most suitable to the system, but as a result the device does not work.

Let's see how to start the BIOS in update mode. Some systems have a special function for this in the advanced settings (something like BIOS Update). If such an item is present in the menu, there is nothing easier than updating the primary system via the Internet. If you want, you can download new firmware for your version, however, it is worth remembering that an incompatible version during installation can cause a huge problem when the computer device turns out to be inoperable at all.

The question of how to launch the BIOS for updating in the form of UEFI is solved quite simply. Need to download executable file on the developer's website (for laptops - manufacturer), and then just run it. What is most surprising is that the update starts not from the primary system, but in Windows environment. You just need to run the appropriate EXE file and wait for the preparation process to complete, after which the reboot will occur computer device, and even before Windows start the primary system in the form of UEFI will be updated (a second restart will follow the upgrade).

Reset. And what to do if the system does not start?

Finally, let's look at the question of how to start the BIOS if the computer or operating system does not start. Not only the microcircuit installed on the motherboard is responsible for the settings of the primary system. Supports permanent saving of parameters and a CMOS battery. If your computer cannot start, simply replace it. By removing the working “tablet” for about five minutes, you can achieve full reset BIOS settings to factory ones. Quite often, this technique allows you to get rid of many problems associated even with the operating system.

After this, the first thing you will have to do is set the time and date, since similar settings are in the Windows systems themselves, for example, when running automatic updates, if system time in BIOS will be different from installed Windows, will generate an error, since it is the parameters of the primary system that have priority over the secondary (operating) system.

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 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. 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. 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! 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 different ones, in addition, in different Windows versions also the keys can 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's worth noting that there are a huge number of options that can change how a 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:

Modern BIOS version They look different, but they have the same task - initial setup and checking the computer's functionality. You can also access them using the same methods. Even if you have a UEFI interface, which often differs not only appearance, but also support for the mouse and the Russian language.

UEFI interface / pcInside.info

To move to BIOS menu on desktop computer, when loading you need to press the Del key, in rare cases - F2. Usually desired key is indicated on the screen before information about the operating system is displayed. The message looks something like this: “Press F1 to continue, DEL to enter setup”, “Press DEL to run setup” or “Please press DEL or F2 to enter UEFI BIOS settings”.

You need to press the specified key exactly at the moment such a message is displayed. To be sure, you can press several times. But if you still don't have time, wait until it starts and restart your PC to try again.

Try only one key each time you boot. You may simply not have time to check several options.

Depending on the manufacturer, year of manufacture and series of the laptop, you can enter the BIOS in different ways. Various keys or even are used, and there may not be messages on the screen indicating the required ones.

It's better to check only one of them possible options at a time. If it doesn't work, wait Windows startup, restart your PC and try a different key or combination. It’s not worth checking several options at once, as you may simply not get it in the right period of time.

Asus laptops

Most often, the F2 key is used to enter the BIOS when turning on the laptop. Less common options are Del and F9.

If this doesn't work, turn off your laptop, hold down Esc, and then press the power button. Do not release Esc until the screen displays Boot menu. In it you need to go to Enter Setup and press Enter.

Acer laptops

IN Acer laptops The most commonly used keys are F1 and F2, as well as the combination Ctrl+Alt+Esc. In the series Acer Aspire Ctrl+F2 may be required. In the TravelMate and Extensa lines, you usually need to press F2 or Del to enter the BIOS. In older models of Acer laptops, the combinations Ctrl+Alt+Del and Ctrl+Alt+Esc may occur.

Lenovo laptops

To enter the BIOS on Lenovo laptops most often you need to press the F2 key. On many ultrabooks and hybrid laptops, a number of F-keys can only be activated using Fn, which means you will need to press Fn+F2. The F8 and Del keys are much less common.

Vaio series models may have special button ASSIST. If you click on it while the laptop is booting, a menu will appear with the option to select Start BIOS Setup.

Older laptops may use the F1, F2, F3, and Del keys.

Dell laptops

In case of Dell laptops The most common option for going to the BIOS is the F2 key. Slightly less common are F1, F10, Del, Esc and Insert.

How to enter UEFI from Windows 8, 8.1 and Windows 10

IN latest versions On laptops with UEFI, you can enter the I/O subsystem even when the system is already loaded. To do this, you need to go to “Settings” and act depending on the version of the operating system.

For Windows 8

“Change computer settings” → “General” → “Custom boot options” → “Restart now” → “Diagnostics” → “ Extra options» → UEFI Firmware Settings → Reboot.

For Windows 8.1

Change PC settings → Update and recovery → Recovery → Special boot options → Restart now → Diagnostics → Advanced options → UEFI Firmware options → Restart.

For Windows 10

Update & Security → Recovery → Custom Boot Options → Restart Now → Troubleshooting → Advanced Options → UEFI Firmware Options → Restart.

For Windows 10 there is also alternative way navigating to UEFI from the login screen or through the Start menu. In both cases, you need to click on the “Shutdown” icon and, while holding Shift key, start reboot. This action will open the section special options system boot.

After this, you will need to follow the same steps as in the previous method. That is, you will need to go to the “Troubleshooting” item, select “Advanced options” and “UEFI Firmware Settings”, and then click “Reboot”.
