Asus immediately goes into the BIOS when turned on. Using a special button without a keyboard
Updated: 12/27/2018 Published: March 13, 2018
Description
Every time you turn on the computer, the BIOS immediately opens (a blue window with settings). After exiting it, either the system starts or only the BIOS loads again.
Very often, this can happen with laptops from ASUS or Samsung.
Cause
- The settings of the basic input/output system have gone wrong;
- The BIOS launch key is stuck (usually Del or F2);
- There is no media to run the operating system;
- Software error BIOS;
- Warning about computer malfunction - launching the menu indicates the presence of incorrect setting, which can lead to failure of the PC itself. For example, incorrect bus frequency.
- Media failure.
Solution
Solutions are arranged in order of ease of diagnosis and implementation on desktop computer. For laptops it is easier to do in the order: 2, 4, 1, 5, 3, 6, 7, 8.
1. Turn on Launch CSM
In case of using systems that do not support UEFI (for example, Windows 7), it is necessary that the “Launch CSM” option is enabled (this option is responsible for compatibility with older operating systems). If it is turned off, first find the option “ Secure Boot"- turn it off and restart the computer. Then we activate Launch CSM.
* sometimes the option may be absent, but a compatibility mode with other systems may be present.
2. Save the settings
The BIOS may appear constantly because you just need to save its settings one-time (for example, after replacing one of the components). To do this, go to the “Exit” section and exit, saving the settings. For example:
3. Checking the keyboard
We try to gently tap the BIOS launch keys. Usually this is Del or F2 ( full list in the article How to enter BIOS). If they are stuck, this may help, otherwise, we completely disable the keyboard (the laptop will have to be disassembled for this).
4. Set up the Boot section
The BIOS may constantly start because the computer cannot find the boot area and start operating system. In this case, the “Boot menu” may start immediately.
Go to the “Boot” section and check that the download starts with hard drive:
* if the disk is not in the list of launch devices, check the tightness of the wires. It is also possible that the carrier itself has failed.
5. Reset BIOS settings
First, we try to reset the settings in the BIOS itself. To do this, in the “Exit” section we find an option with a name similar to “Load Default”, for example:
If this does not help, try resetting the settings by removing the battery on the motherboard.
6. Change the battery
If BIOS settings appear every time after turning off the computer/power supply, this may indicate that the battery is dead. To replace it, we disassemble the computer and find it on the motherboard. Roughly, it looks like this:
The battery itself can be purchased in many stores. Markings for different boards may vary slightly (usually CR2016, CR2025 or CR2032). The easiest way is to take out the battery and bring it to the store.
7. Check the connection of the disk drive
Disable hard cables disk from the motherboard and the disk itself on which the bootloader is located. We check that there is no dust in them and connect them again:
Also, connect the drive cable to another connector on the motherboard. You can also try replacing the power connector.
8. Changing the disk
We check the performance of the disk. To do this you can:
a) See if the BIOS disk is visible in the partition Main.
b) Disconnect the disk from the computer and insert it into another, checking that it is detected and data can be read from it.
c) Boot the computer from boot disk Windows LiveCD and check the status of the media on which the system is installed, for example, with the CrystalDiskInfo program.
If the disk is not detected or its condition is determined to be critical, then the disk itself must be replaced.
Using a computer or laptop sooner or later leads to the need to reinstall the system. The average user, when trying to boot the system from external media encounters such a concept as BIOS. The instructions say that you need to enter the BIOS, but many computer users do not even know what this abbreviation means and what meaning it carries.
BIOS deciphered as “Basic Input Output System”, that is, “Basic Input-Output System”. BIOS is a set of programs for input and output of data for system management. Modern computers switched to a more advanced form of the basic system, which is called . However, the essence of its use has not changed.
Standard ways to launch BIOS
Without special need to enter the BIOS for a person who does not understand computer systems, is not advisable, as this can lead to disastrous consequences. When logging in, a person has access to many system parameters. Changing them may adversely affect the operation of the computer. So if you don't understand the meaning changeable settings, it's better not to touch them.
The most common reason why regular user there is a need to enter the BIOS, associated with a change in the initialization sequence of devices and forced installation or disk. There are several ways to enter the BIOS. This requires a keyboard, but there are also ways to enter the BIOS without a keyboard.
In order to enter the BIOS, you need to follow the specified scheme. In fact, entering bios will not be difficult. Another question is how to change and use these settings.
Input scheme in BIOS:
Sometimes the line pops up very quickly and the person does not have time to enter the BIOS. This is not a problem, you just need to wait until the computer turns on and restart it. When turning on, repeat these steps again.

How to enter the BIOS in other ways
The standard method of entering the I/O menu requires a keyboard. However, there are some ways login without using it. Typically, this need arises if the keyboard is broken or the settings have been changed, causing in the usual way I can't enter the BIOS.
Using a special button without a keyboard
There is a special button for entering the BIOS on some computer models, for example, Lenovo. You don't need to restart your computer to use it. It is active in any case and allows us to immediately enter the system we need.
The disadvantage of this method is that not all computers have such a button, but it is this button that allows you to enter the BIOS without using the keyboard at all.
Resetting BIOS settings
This method allows you to reset the settings for entering the BIOS in the usual way. To do this, we find under the body system unit find the jumper " Clear CMOS", change its position and return it back. This way, the settings will be reset, which means you will be able to enter the BIOS in a standard way using the keyboard.
If jumper missing, then you can remove the BIOS battery for 20-30 seconds and put it back in. It's not difficult to find. It is quite large and there are no other batteries on the motherboard.
Using a PS/2 keyboard
The problem that prevents you from entering the I/O menu may be hidden in the keyboard. This happens on older computers. The solution is to use a keyboard with a PS/2 connector.
How to load bios via command line
One of the simplest and available ways, understandable to every average user, is to enter the BIOS using command line . The essence of the method is to run just one command and easily and quickly enter the BIOS.
Step-by-step process for entering BIOS via the command line:
1 step. Hold down the keys Windows and R. In the window that appears, enter “ cmd", as shown in the screenshot. 
Step 2. We are waiting for the command line window to appear. 
Step 3. In the window that appears, enter the command to call the system reboot "shutdown.exe /r /o", as shown in the picture, and press Enter:
After implementing these simple actions the computer will begin to reboot. When turned on, the menu will open in various ways launch. There will be a key combination for the simplest and quick login in BIOS.
Is it possible to enter the BIOS without rebooting?
If none of the above methods helped you enter the BIOS, you should seek help from a specialist. It is impossible to enter the BIOS without rebooting, since it is when you turn on that the input and output menu is active, when running computer BIOS no longer works.
In the section on the question What to do if the system automatically loads the BIOS at startup. I launch it and immediately goes into the BIOS. The keyboard doesn't jam. given by the author I-beam the best answer is It's quite possible there's a bug in the BIOS. Try resetting it (as already advised). In addition, the battery could stupidly run out, the settings get lost, so he swears. Change the CR1232, I think. It costs 15 rubles in a computer
Well, to the extreme. My parents had a similar story. Every boot I swore at something and went into the BIOS. I tormented it for 1.5 years, then I came to the conclusion that the BIOS version needed to be flashed. I dug up the latest one and installed it.
It was terribly scary, but nothing. It worked out. But now at least he squeaked once... .
PS About removing the battery (answer above) is not entirely correct. More precisely, it has not been correct for a long time.
1. There is Load default values in the BIOS itself
2. Removing the battery helps only in old mothers.
3. In newer mothers, next to the battery there is a jumper and 3 pins. Closed 2. Now you need to close the middle and free ones for 5 seconds. Then put it in place. This is a reset.
Answer from Separated[guru]
try resetting the bios
Answer from Igor Sokolov (RA2FCZ)[guru]
Apparently in the BIOS there are such settings, reset to default. Just take the battery out of the motherboard for 5 minutes and put it back in
Answer from Valery[master]
The best option is to change the battery
Answer from Serve[guru]
I met one like that. Look carefully at the POST messages (can fly by quickly, pause can help), as options: dead battery (date will be reset, replace), screwed up with the settings (reset to default), error of some device.
Greetings, dear readers! You know, this probably wouldn't be a blog with computer tips, if I had not written anything about such a system as BIOS.
I'm sure every day search engines they ask this question, how to enter BIOS, and today I will try to tell you about this system and how to log into BIOS on different computers.
What is BIOS?
Let's first figure out what it is. In professional terms, this is:
(English basic input/output system - “basic input-output system”) - part of the system implemented in the form of microprograms software, which is intended to provide the operating system Access API to the computer hardware and devices connected to it.
Well, to put it simply, then BIOS this set of microprograms is written in system board. Even before the operating system starts loading, BIOS performs a lot of useful and required functions. For example, there is such a very important task for BIOS, this is a check of all computer components - POST.
As soon as you press the power button on your computer, the procedure starts POST, which checks for serviceability and availability of all computer components (video cards, random access memory, hard drive, and so on) and if any of the components fails, it displays an error by which one or another failure can be determined. It is also issued sound signal, but it seems to me that this happens on older computers; I haven’t seen this on new ones.
The BIOS also controls the loading of the operating system and indicates which source to boot from (DVD/CD drive, HDD, or a connected flash device). This is especially true when installing an operating system; I’ll write about this below. The BIOS also stores a lot of different settings, which can be changed. For example, I overclocked my processor a little through the BIOS by increasing the system bus frequency.
How to enter BIOS?
In order to enter BIOS system, immediately after pressing the computer’s power button, you need to diligently press the key, but we’ll figure out which one now. The fact is that different manufacturers motherboards or laptops have their own key combination to enter the BIOS. Usually these are keys Del , F2, or Esc , there can also be combinations different keys, and that’s why I’ll post a table in which you can see the keys for entering the BIOS from different manufacturers.
What to do in BIOS?
An interesting question with many answers. First of all, you need to go into the BIOS before starting Windows installations or another OS. The thing is that by default loading computer is coming from the hard drive, and to install the operating system we need to boot from a DVD/CD drive or flash drive, such settings can be set by going to the BIOS, more about this is written here
Everyone who actively uses their PC sooner or later is faced with the need to enter the BIOS. However, this does not always work out. Now we will talk about how to enter the BIOS, and also look at the basic settings that are available to the user there.
The name BIOS is an English abbreviation that stands for basic input/output system or Basic system input and output. BIOS is one of the main systems of any PC; it is responsible for turning on the computer, starting connected components, loading the operating system, as well as interaction of the operating system with the hardware. It can be said that on basic level The BIOS controls the entire computer.
In what situations does it become necessary to enter the BIOS:
- Overclocking your computer. Using BIOS you can specify not standard frequencies and voltages for the processor, memory and other components. This way, you can improve the performance of the processor and the entire computer.
- Selecting a disk to boot the operating system. In the BIOS, the user can specify the drives from which the operating system should boot. In this case, it is possible to specify several drives from which loading is possible. In this case, the computer will try to load the operating system from the first drive, and if it fails, it will move on to the next one.
- Enable or disable integrated components. Some integrated components (for example, sound card) can be disabled and enabled via BIOS.
- Setting the system date and time. Through BIOS you can specify system date and time. When the date and time information is also reset, after which you need to set the system clock again.
- Computer health monitoring. Through the BIOS you can access some data about the state of the computer. For example, you can.
- Turn on or off some specific computer features.
In order to enter the BIOS you need to click on special key on the keyboard while the computer boots, almost immediately after pressing the power button.
Most often, when the computer boots, a message appears on the screen telling you which key you need to press. This message looks something like this: “Press Del to enter Setup” and appears at the bottom of the screen immediately after the computer starts booting. In most cases, in order to enter the BIOS you need to press Delete. Therefore, if when you boot your computer you do not see a message about which key you need to press, then try Delete first.
However, it is not always used Delete key. Sometimes other keys or even key combinations may be used.
Keys that are most often used to enter BIOS:
- DELETE
In addition, on some PCs, the following key combinations can be used to enter the BIOS:
- Ctrl+Alt+Esc
- Ctrl+Alt+Ins
- Ctrl+Alt+S
- Ctrl+Alt+Del
- Ctrl+Alt
- Fn+F1
- Ctrl+Ins
- Ctrl+Alt+Enter
After you have entered the BIOS, you can navigate through all its items using the keyboard. Let's look at the main keys that are used for control:
- Arrows – move up, down and sideways;
- F1 – open partition using;
- F6 or F9 – set standard settings;
- F10 – save all changes in settings and exit;
- Enter – enter the selected menu;
- Esc – back or exit. Using this key you can go back to the previous screen. If you are on the first screen, you can use the Esc key to exit and restart your computer;
- Plus and minus keys – Change value. Use the +/- keys to change the selected value;
- Tab – select a value;
