The BIOS is an assembly of firmware that regulates the operation of all devices and the loading of the operating system. In essence, this the most important component of any processor. The BIOS is located in the motherboard because the motherboard is responsible for managing all the devices on the computer.
In certain situations, there is a need to enter the BIOS. There are many ways to do this, either using input devices (keyboards) or without it.
We will tell you how to enter the BIOS if the keyboard does not work.
Special button to enter
To enter the BIOS in modern laptops (for example, Lenovo brand), the keyboard has a special button. It allows you to quickly move to settings without requiring a reboot.
However, this button is not available on all laptops, and on personal computers it is a rarity. But This is the most effective way to enter the BIOS without touching the keyboard.
IMPORTANT! In personal computers there is a button located on the case reset. In order to reset the BIOS, you must turn off the computer and hold down the RESET button for five seconds.
Forced cleaning with battery removal
On devices that do not have a special button for quick access to BIOS, you must perform a forced cleaning. It is carried out by removing the battery.
Forced cleaning algorithm
- Turn off the computer. To ensure complete discharge of the capacitors, you need to hold down the power button several times.
- After that, we find in the block (or inside the laptop case) a battery that its appearance is like a coin.
- Gently pull it out.
- After five seconds, insert the battery into place on the same side.
After these actions, the BIOS settings will be reset, and the keyboard will work again.
How to enter BIOS in Windows
For operating systems Windows 8 and Windows 10, there is another way to enter the BIOS settings - using the mouse.
To do this, follow these steps:
- In the "Options" select "Update and Security."
- Then open the "Recovery" item and select the "Special boot options" menu. Click on "Restart now."
- After rebooting, a menu for selecting actions appears. Click on the "Diagnostics" option.
- Next, go to the "Options".
Using this method, you can easily start the BIOS without using a keyboard.
An alternative method of entering BIOS settings
In addition to the above methods, There are also methods that will help you restore BIOS factory settings without using a keyboard.
Jumper Manipulation
To perform a factory reset in this way, do the following:
- Disconnect the computer from power.
- Open the system unit cover and look for the trigger (Clear CMOS). We change its position for a while (from 10 to 20 seconds).
- After this time, we return it to its original position.
When if such a trigger was not found, it means that you have two contacts. Therefore, to perform this manipulation use a conductive tool (preferably with a screwdriver). Contact clamping required for approximately 20 seconds. After that, just turn on the computer and make sure that the keyboard works.
