It is the software that is responsible for the work of all the components of the laptop. The BIOS prepares the system for inclusion, adjusts the equipment. This software is also called Setup.

Initially, the BIOS was needed for maintenancedisk drives, monitor, computer. Today it performs many more tasks, including finding the right partition and sector on the drive, setting up the bootloader. In modern laptop models, manufacturers are increasingly using the new EFI interface instead of the BIOS. His scheme has great potential. For example, subroutines are now embedded between the operating system and the drive.

The reset must be carried out after the laptop is completely turned off. At this point, all devices, including the power supply, must be disconnected from the laptop. There are several ways to reset the BIOS.
- Jumper.Find the jumper between the two pins on the board, pull it out, put it between the second and third pins for fifteen seconds, then put it back in place. The method is suitable for users who know the device board.
- Contacts.Resetting the BIOS on a laptop can be done if you close several contacts with something metallic by removing the jumper. This can be done only with some models. Turn off the device, take a small screwdriver, close the two contacts for a few seconds, then turn on the laptop.

After the main menu is open, use the arrows on the keyboard to change the system time (day, month, year). It is important that it is correctly installed. Resetting the BIOS on an Asus laptop, for example, is practically no different from this procedure on models from other manufacturers, so in any case, the user should have no problems. So, the main settings:

- The Security section allows you to configure the security of the device. If the laptop is intended for home use, it does not require changes. Actual for office PCs.
- Boot section helps to change boot settingsOS If a CD-ROM is installed as a boot device, it will check this particular disk before launching the BIOS. If he finds nothing, the start will happen from the hard drive. Experts advise to change the parameters of Boot. Settings depend on the motherboard. Put the cursor in front of the First Boot Device parameter, press Enter. When a new window appears, find the item Hard Disk (hard disk), confirm by pressing Enter. Next, select the line Second Boot Device and change the settings on the CDROM. Then find the Third Boot Device and set Disabled.
