Setting a password on BIOS can be both an effective solution to unauthorized access to a computer, and a problem that will make a not very experienced user nervous. This article discusses not only the installation of protection on the system program, but also how to remove the password from the BIOS if the user forgot it or it was installed without his knowledge.
Password Effectiveness
Windows system protection is far from the most advanced and reliable. It can be easily hacked using special software or simply reinstalling the operating system.
With a password on the BIOS, everything is much more complicated. By setting a password for the system program, the user will definitely not be able to get access to Windows or access to the BIOS itself, which will significantly complicate the use of a computer without knowing the security key.
However, this does not mean that the PC is under strong protection. Yes, this protection is more reliable than the operating system, but it can also be hacked by certain manipulations. How to remove the password from BIOS will be described below, but first you need to install it.
Installation of protection on BIOS
First, restart the computer, and as soon as the PC starts to start, go to the BIOS by pressing the Delete button (F1, F2, F9 - depending on the version of the system program).
The following image will appear on the screen (it also differs in different versions of BIOS):
There are two points that establish protection on the system:
- set supervisor password;
- set user password.
The first sets the password for the administrator, and the second for the user. User access is different in that you can use it to view BIOS values (but not change them) and use Windows. The administrator password gives full access to the owner. If you install only supervisor password, it will be requested only when entering the BIOS. Setting a user password will limit the loading of the operating system. For complete computer protection, it is better to install two security codes at once.
On other computers, the password setting process may vary slightly. The security tab (located at the top can be responsible for this, you can get into it using the arrows at the bottom of the keyboard) and bios setting password. The procedure for installing protection is almost identical - only the terms differ.
Next, select the appropriate item and enter the passwords. The BIOS is exited through the F10 button, in the window that appears, press Y and enter to save all the changed parameters.
How to remove a password through BIOS
Removing protection can occur for various reasons, but the easiest way to do this is through the BIOS itself.
We go to the security / bios password tab and look for the clear password parameter. To confirm the action, you will need to enter a password, and then exit, saving the original data.
How to remove the password from BIOS for those who look like in the first image. You must click set password, and after confirming the valid password, when prompted to install a new security code, click the delete button. Password reset - you can exit without forgetting to save all the changed parameters through F10.
This method only works if the user remembers his password. But how to remove the password from the BIOS on the computer, if you do not remember it? This is a bit trickier.
BIOS memory reset
This is the most digestible way to reset your password if the method described above is not suitable. Often users forget the security keys, and resetting the BIOS memory is the only way out.
To clean the BIOS, you need to short-circuit certain wires on the motherboard. It is not recommended to do this without involving a specialist - there is a much easier way.
To safely reset the BIOS memory, you need to remove the CMOS battery for a while, then insert it back.
That's what she looks like.
Take out carefully so as not to damage anything.
How to remove a password from BIOS on a laptop
Removing the battery from a laptop or tablet running on Windows is much more difficult. The whole process is complicated by disassembling the laptop. Not every user can do this on their own.
But there is a way out. This will require:
- another working device;
- BIOS password generator.
The following is the procedure for removing the password:
- Download the laptop and enter BIOS through the corresponding button.
- In the security code request window, enter the wrong password three times, after which the laptop will give a system error.
- Record the error sequence number and enter it into the password generator.
- Generate a standard security code and enter into the appropriate BIOS field, after rebooting the laptop.
- Reset the password according to the instructions above.
The BIOS password generator can be found through a search engine - there are a large number of them on the Internet, or as an application for Android or IOS.
A user who knows how to remove a password from BIOS will not get into a difficult situation if someone by mistake or intentionally sets him a password for a system program.
You can remove the password directly through BIOS by going into it and setting the clear password parameter. But this is only possible if the user remembers the security code. In cases where the password is lost, you will have to reset the memory physically or generate a standard password through the appropriate program.
