Solution to the problem of entering the BIOS interface when the computer is turned on: 1. Purchase a replacement motherboard battery and reset the correct parameters in the BIOS interface; 2. Press the DEL key to enter the BIOS, and then press F9 to load the predefined parameters ;3. Repair the hard disk master boot record or reinstall the system or replace the hard disk.
#1. Battery failure: You can check whether the system time is accurate in the BIOS interface. If it is not accurate, it can be determined that the motherboard battery has failed, causing the computer to call the BIOS default If the parameters are inconsistent with the local hardware environment, the computer cannot be started normally. You can purchase the motherboard battery to replace it, then turn on the computer and press the DEL key (F2 or other designated hotkeys for notebooks) to enter the BIOS interface, reset the correct parameters, and finally press F10 to save, exit and restart.
2. Configuration error: This situation may also occur because the manually configured BIOS parameters do not match the local hardware environment. If you don’t know how to set the parameters, generally you can press the F1 key to skip non-fatal errors and start the computer directly according to the white text prompts on the black background, or press the DEL key to enter the BIOS, and then press F9 to load the predefined parameters or select Load Optimized Defaults (load high-performance defaults) or Load Fail-Safe Defaults (load fail-safe defaults),
3. Hardware failure: If the above operations are invalid, it means there is a problem with the hardware. Generally, it is caused by poor contact between the memory and the hard disk or the hard disk master boot record is damaged. It is necessary to re-insert the memory or hard disk, repair the hard disk master boot record, reinstall the system or replace the hard disk.
BIOS is the abbreviation of "Basic Input Output System" in English. When translated literally, the Chinese name is "Basic Input Output System". In fact, it is a set of programs solidified on a ROM chip on the motherboard of the computer. It saves the computer's most important basic input and output programs, post-boot self-test programs and system self-starting programs. It can be read and written from CMOS. Specific information about system settings. Its main function is to provide the lowest and most direct hardware settings and control for the computer.

Functionally, BIOS is divided into three parts:
Self-test and initialization
This part is responsible for starting the computer. There are three specific parts:
The first part is used to detect the hardware part when the computer is just powered on, also called Power On Self Test. POST for short), the function is to check whether the computer is in good condition. Usually a complete POST self-test will include the CPU, 640K basic memory, extended memory above 1M, ROM, motherboard, CMOS memory, serial and parallel ports, graphics card, soft and hard disk subsystem and The keyboard is tested. Once a problem is found during the self-test, the system will give a prompt message or sound a warning.
If an error is found during the self-test, it will be handled in two situations: for serious faults (fatal faults), the machine will be shut down. At this time, since various initialization operations have not been completed, no prompts or signals can be given. ; For non-serious faults, a prompt or sound alarm signal will be given, waiting for user processing.
The second part is initialization, including creating interrupt vectors, setting registers, initializing and detecting some external devices, etc. A very important part of it is BIOS settings, mainly some parameters of hardware settings. When the computer starts, it will read these parameters and compare them with the actual hardware settings. If they are not consistent, it will affect the startup of the system.
The third part is the boot program, whose function is to boot DOS or other operating systems. The BIOS first reads the boot record from the beginning sector of the floppy disk or hard disk. If it is not found, it will display on the monitor that there is no boot device. If the boot record is found, it will transfer control of the computer to the boot record, which will then control the operating system. After the computer starts successfully, this part of the BIOS task is completed.
