So, how do you enter CMOS settings in a laptop?

First, enter the CMOS settings

The notebook also has CMOS settings, but it enters the CMOS settings, but it is very different from the desktop. When the laptop is turned on, you can't enter the CMOS settings when you press the Del button. Many brands of laptops require you to press the F2 key to enter the CMOS settings. This is mainly to see what BIOS your host uses, because different BIOS has different entry methods, but the general laptop will prompt on the boot screen.

Most domestic (including Taiwanese) brand notebooks enter the BIOS: (press F2 when starting and restarting)

Second, set the laptop BIOS password

Since most laptops are carried around, it is necessary to use passwords to prevent others from stealing computer data.

The BIOS password of a laptop is generally divided into a User Password, a SuperVisor Password, and a Hard Disk Password. Some models also have a special setup password. These passwords are usually stored in a dedicated cryptographic chip or written in FlashROM. Both the power-on password and the super-user password can restrict others from entering the system. The only difference is that the super password has the right to completely modify the BIOS settings, but the user password does not. Simply put, if you enter the BIOS with a user password, some items will become unsettable. Since most laptops have more chances to use themselves, it is recommended to use a super password to lock the laptop, which can protect the computer security and have full permissions. Just if you set a super password, the password must be kept in mind. If you forget the password, it will be awful. This is very likely to make the "board scrapped." Even if you go to the manufacturer to help, their solution is mostly a new one. Motherboard.

The setting method of super password is:

1. After turning on the power, press F2 to enter BIOS;

2. Switch to “Security”;

3, then move the cursor to "Set Supervisor Password";

4, enter the password to be set;

5, then "Spervisor Password Is: Set", indicating that the password has been set Finished;

6. Finally, set the “Password on boot” option to “Enable”, and set the password to be entered when booting. All the settings are complete.

When we reboot again, the laptop will not enter Windows directly. Instead, we will ask you to enter your password. After entering the correct password, the computer will be able to successfully boot. If you enter the error, you can try again. If the system is completely deadlocked 3 times, you must turn off the computer and then turn it back on.
