How to enter BIOS on laptops and desktop PCs. Where is the BIOS located? Example of location on the motherboard

Useful tips

Quite often, users have a question: How to open BIOS on a laptop and what is it? The basic input/output system is responsible for normal start PC and the operation of its devices.

What circumstances force you to run the BIOS?

Integrated computer components need to be turned on or off.
Replacing the video card. Many laptop computers have two graphics cards built into them. Thanks to the input-output system, the user selects either the first or the second.
Setting up special laptop modes. Here the computer owner can configure various modes (hibernation, sleep mode).
Adjusting the time in the system. The system allows you to adjust the time that requires such manipulations, often after resetting the settings.
The need to check the “well-being” of the computer. Through Bios you can monitor many PC parameters.
Return standard settings. By opening the control system, you have the opportunity to restore the system settings to their original state.

This article will describe step-by-step algorithm How to run Bios on a laptop. After reading it, you will understand that opening this system on your computer is not difficult.

Running the system on a desktop computer and a laptop does not have any special differences.

Starting the I/O system

Firstly, to open it, you need to restart your computer. To do this, you will need to click on the “Start” button and find the shutdown/restart button in the panel that appears. The button is located in the lower left corner of the panel.

You can also restart the device by pressing and holding the start/shutdown key, which is (most often) located in the upper right corner of the keyboard. After complete shutdown laptop, you need to press the same key again and start the computer.

You need to open the settings before executing full load computer. Most often, when loading, it says at the bottom: Press F1 to enter setup (press F1)

In addition to F1, there can be any other keys, for example:

DELETE

Sometimes you need to press a combination:

Ctrl+Alt+Del
Fn+F1
Ctrl+Alt+Esc
Ctrl+Alt
Ctrl+Alt+Ins
Ctrl+Alt+S
Ctrl+Ins
Ctrl+Alt+Enter

If you did not have time to press the buttons to log in, you should turn off and start the computer again.

Having completed all the steps correctly, you will see a window open in front of you.

Now let's look at how to run the setup on PCs from different companies.

The article will tell you how to enter the BIOS from different laptop models. You will receive some information about what settings can be made in it, you will also find out what BIOS is, what it is intended for and what role it plays in system device computer.

In the language of programmers, BIOS is a basic input/output system that contains the main computer settings: date and time, processor operating parameters, settings of connected memory drives, etc. The average PC user rarely has to make any changes in the BIOS, but if you decide to disable the device check function or overclock the processor (using proven instructions), you will have to go into the BIOS and change some options.

If you are wondering what BIOS is under the lid of your laptop, the answer is simple - it is a chip located on motherboard, which starts working when you turn on the computer. To get in BIOS menu It is possible just at the moment of loading the operating system. To do this, different laptop models have a special key combination (or one key), by pressing which the user enters the BIOS. Which key should you press? the main problem users who do not know how to enter the BIOS from their laptop.

As for desktop PCs, this is usually DEL. But first things first.

Main BIOS sections

On any laptop model, the BIOS sections are approximately the same. Let's briefly look at each section:

Main – designed to set basic computer parameters, such as: processor type, memory size, date and time. Here and in the next section, users make the necessary settings to increase the speed of the computer processor
Advanced – these are advanced settings, which are generally not recommended if you are not sure that you are doing everything correctly. In a word, by activating “something there, somewhere there” in this section, you can simply break the laptop, it will stop starting and you will have to take it to a service center. But, with certain skills in overclocking computers, this section will become a testing ground.
Power – the section is responsible for distributing energy to system components from the power supply: motherboard, processor, video card, additional coolers. Typically, this section is in demand if you decide to update system components. But it is better to entrust the settings to a professional.
Boot is an important section used when Windows installations. In it you can choose whether the computer will boot when entering the OS data from hard drive, either from a disk drive or from a flash drive. If you are planning to reinstall Windows, instead of the hard drive, select external device With installation files OS and, having saved the settings, continue starting the computer; the program should start automatic installation OS with external media.
Exit – is responsible for how to exit the BIOS. Press it after making the necessary settings, just don’t forget to save them. Example (see picture below): you need to press F10 to save the changes; when you exit the BIOS, press Exit and the OS will resume loading.

How to open BIOS: common combinations

Try using these keyboard shortcuts if you tried to use the keys for your laptop model, but you were unable to open the BIOS or you did not find information on your laptop model in our article.

So, you restart your computer and until the welcome window appears, which reproduces your operating system, must guess the correct key to open the BIOS. We recommend that you first try pressing ESC to reset the introductory screen. On some laptop models, a window appears (see screenshot below) where it is written which keys are responsible for entering the BIOS. By the way, if this information window appears but disappears too quickly and you don’t have time to read anything, try using the Pause button located on your keyboard.

If this method does not work, or does work, but the keys are not indicated in the window, you need to act at random. First of all, try all the buttons of the first option; if the problem is not solved, go to the second.

F1, F2, F3... F12 - most laptop models allow you to enable the BIOS by pressing one of these keys.
Ctrl or Alt button combinations: Alt+Esc, Alt+Enter, Alt+Del, Alt+ Insert - any of these combinations may be relevant for Chinese laptops or laptops of outdated models.

How to enter BIOS on an Asus laptop

The advantages of Asus laptops are that, regardless of the model, you can enter the BIOS in one way. Thanks to the manufacturers, unlike their colleagues in the shop, they did not bother device owners by introducing different keyboard shortcuts for each laptop model. Bios on Asus laptop usually has classic look, which will be understandable to every user.

A method that works on all operating systems

It doesn’t matter what system is installed on your Asus laptop computer, any model (with the exception of some Chinese fakes) of the Asus laptop allows you to open the BIOS if you use the following procedure:

While the computer is turned off, press and hold the F2 button;
press the laptop power button;
after 5 seconds, release F2, you will see the BIOS menu.

Method for Windows 8

You can't get into the BIOS on Windows 8 in the usual way, for this you need to do the following chain of actions: go to “Parameters”, in the “Change” section; go to “General”, “Special Settings”, “Restart Now”; will appear blue screen, you need to select “Diagnostics”, then click “Advanced”; Now click on UEFI Firmware Settings.

Restart your computer. After turning on, the BIOS menu should immediately appear on the laptop screen. Sometimes, on some models, this option may not work (then you need to use the classic method). It doesn’t matter which of these two methods you get into the BIOS on an Asus laptop, it’s more a matter of habit or convenience.

How to open BIOS on an HP laptop

All HP laptop models behave adequately, i.e. There are no problems with how to get into the BIOS on an HP laptop, but there is one exception - the HP Pavillion. The Internet is full of questions from owners of laptop computers of this model, they all ask for one thing: help figure out how to prioritize a bootable USB flash drive in order to successfully reinstall the OS. We will also look into this issue, but first classic way How to enter BIOS on an HP laptop.

Method for all HP laptops

When you turn on the laptop, you need to press the ESC key until the HP logo appears in the center of the screen. A list of active keys should appear:

F1 – system information;
F2 – system diagnostics;
F9 – change boot settings;
F10 – BIOS settings.

To get into the BIOS, press F10. Immediately after pressing the button, a menu with sections should appear. Appearance BIOS window depends on specific model laptop, motherboard, so don't worry if yours looks different. In the menu with sections (see screenshot below) all the necessary functions for managing computer settings are available.

HP Pavilion G6 laptops - how to make a bootable USB flash drive active

It is worth noting that only the HP Pavilion, out of the entire series of HP laptops, encounters difficulties with reinstalling the operating system. So, first you need to enter the BIOS on the HP Pavilion in the usual way: after pressing ESC, in the list of functions that appears, press F10.

If not all, then most users have come across the concept of BIOS and the parameters of this basic system. True, sometimes for some reason you need to completely reset its settings. That's when people start taking apart computers and laptops, trying to determine where the BIOS (chip) is located. To avoid any misconceptions regarding the location of this element of the system, we will try to consider all aspects related to this.

What is BIOS and why is it needed?

Before considering the question of where the BIOS is located on a laptop or in a desktop computer terminal, let's see what it is and what this whole system is for.

In general, if you look at it, BIOS can be characterized in two ways. Firstly, this is, so to speak, the “iron” component of any computer device, made in the form of a microchip. Secondly, this is a software set designed to ensure the functionality of all system elements is checked even before the operating system starts. In passing, it is worth noting that it stores basic information and settings relating to absolutely all devices present in the assembly at the hardware level.

Misconceptions about the location of the microchip

Now a little about myths. Some clearly untrained users often wonder where the BIOS is located in Windows 7, for example. The answer is simple - nowhere! There are no files or folders in the system that are in any way related to the BIOS or its settings.

Another thing is that the operating system sees this device and is able to display information about it brief information, for example, information about the manufacturer, version, etc. To do this, you should use the system information section, which can be entered very easily from the standard “Control Panel”. Here, among all other devices, there is also a BIOS. Where is the information about this chip in Windows 8? Everything is in the same section. However, in order not to look for the same “Control Panel”, you can use the “Run” menu, where the msinfo32 command is entered.

Where is the BIOS located on the motherboard?

Now let's get to the main issue. So where is the BIOS? As many have already guessed, exclusively on the motherboard. Please note that this microchip is not installed, so if you are searching, you should carefully inspect the motherboard. If for some reason the microcircuit is not found, you should thoroughly study the instructions included with the device. As a rule, there is a diagram with a description and location of all elements.

As for installing the chip, there may be two options: removable device or tightly soldered into the motherboard. Owners of removable chips are lucky, because if it breaks, it can be easily replaced. Some manufacturers have gone even further. They install not one chip on their motherboards, but two. In this case, the first is the main one, and the second plays the role of a backup. It is not difficult to figure out that if the first one fails, the second one is automatically connected to work.

To find the microchip itself, you need to look for a black or gray, which, as a rule, has a size of approximately 1x1 cm. Sometimes it may contain a manufacturer’s name like American Megatrends. In some cases there is a holographic sticker on top.

Location options

Some instructions advise looking for the BIOS microchip next to the CMOS battery, which clearly stands out from the general background. It is not always so. The fact is that sometimes there are no microcircuits next to it, and the chip we are interested in can be located quite far away, as, for example, on motherboards manufactured by MSI.

If you look at where the BIOS is located on ASUS A8N-SLI motherboards, the location (in our case from top to bottom) may look like this: battery, memory reset jumper, I/O controller, and only then the BIOS chip itself. By the way, there is a special connector for it, from which it can be removed quite simply.

BIOS battery: where is it located?

Now a few words about the battery. Finding it on the motherboard is quite simple. It is made in the form of a round disk, and its size is two to three times larger than the battery used in electronic watches.

It stands out quite strongly from all other components and connectors, as it has a typical metallic tint.

Why do we need non-volatile CMOS memory?

No matter how universal BIOS device, it can not store all the data about the installed equipment (the characteristics and settings of only standard components are present here). At the same time, chip manufacturers may not know the parameters of other devices connected to the computer.

This is where the so-called CMOS memory, which, in addition to the system clock settings, also stores data about coprocessors, floppy disks etc. Its purpose is to ensure that the stored information is not erased when the computer is turned off. In turn, it is powered by a battery, the charge of which, according to manufacturers, should be enough on average even for several years without power supply. In passing, it is worth noting that resetting the BIOS memory and password is precisely achieved by temporarily removing the battery from the corresponding slot.

Relationship between BIOS, CMOS and ROM

Where the BIOS is located is already a little clear. Now let's look at the relationship between the components described above. It goes without saying that at this stage of consideration of the topic, the question could be formulated this way: where is the BIOS? In part, it will be stated somewhat incorrectly, since the BIOS is, in fact, a set of programs “hardwired” into the ROM.

But let's return to the relationship. The fact is that when the computer terminal is turned on, the processor first accesses random access memory, and, as you know, there is nothing left in it after turning it off. Therefore, the request is redirected to the ROM, where the “hardwired” programs are located that are responsible for the parameters and identification of “hardware” devices. Plus, a system timer is used, the settings of which directly affect the time and date already set in the operating system. Of course, you can change such settings in the operating system itself, but sometimes when certain errors occur, this does not help, and the time and date have to be changed in the BIOS.

How to enter BIOS settings

Finally, let's look at the options for entering the I/O system settings. For desktop computers, as a rule, the input is provided by pressing the Del key, sometimes Esc (a line appears on the screen in the center or below with the corresponding indication: Press ... to run BIOS Setup or something like that.

There are more variations on laptops. For example, these could be function keys, Fn key combinations or special buttons, placed on the keyboard (like the Sony Vaio).

Not to mention where the HP (laptop) BIOS is located, here main role The Esc key plays, after pressing which a short menu appears with indications of the buttons responsible for certain operations. On devices like the HP Pavilion, entering the BIOS from home menu carried out by using the F10 key. In general, you need to look at the BIOS developer, because there can be quite a lot of combinations. An indication of them is given on the start loading screen. True, the message itself lasts only a couple of seconds, and not everyone has time to notice what needs to be done. At such a moment, you can press the Pause key to freeze the line on the screen.

Features of the location of the BIOS chip on a laptop

With laptops the situation is somewhat more complicated than with desktop computers. Actually, motherboards differ quite a lot. However, despite the numerous options for the arrangement of elements, we can say with a certain degree of confidence that many models have a standard arrangement solution.

Most often you need to look for the chip under Wi-Fi module, which may be located under the smallest cover at the bottom of the laptop, above the DVD drive. The battery can be found under the top right corner of the touchpad. But this is not the standard. There may be other options.

Conclusion

Here is a brief summary of everything that concerns where the BIOS is located on different devices what is its purpose and functions. As is already clear, depending on the motherboard manufacturer, the arrangement of some elements may look illogical. However, you can find this chip even if there is no holographic sticker on it or the manufacturer is not indicated. The main thing is a little patience and attentiveness when examining.

In the simplest version, of course, you should first find the battery, and then look around its surroundings, because the motherboard is not that large in size. So the probability of finding a BIOS chip at first glance is quite high.

Apparently, many have already noticed that there can be quite a lot of options for BIOS location. There are so many manufacturers and types of motherboards, so many options. Moreover, even from one manufacturer per different models The microchip can be located in completely different locations. You yourself understand that you simply cannot list everything, although in this case Some unified basic schemes were considered. However, it is enough to look at the instructions for the motherboard so as not to waste time searching. If there is none, and you also need to find the BIOS on the laptop, you can simply go to the manufacturer’s website and find the diagram there. Almost everyone now has the Internet.

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 the installed Windows versions. 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 what was previously an absolute standard BIOS systems from 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 of parameters, but in some cases it can be 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 buttons on the keyboard panel quick access. 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, for this purpose, 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 corresponding EXE file and wait for the preparatory process to complete, after which the computer device will reboot, 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 a complete 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 starting 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.
