BIOS (Basic Input/Output System) is a small program that provides the computer with information on how to download the operating system and interact with the hardware. BIOS is kept in constant memory on the mother ' s fee. However, sometimes users find that every switch on the BIOS computer is dropped to the plant. This may result in the loss of user lines, time and dates.

There are several reasons why BIOS can drop off when the computer is off. One of the main reasons is the weak CMOS battery (Complementary MetalOxideSemiconductor), which provides food for BIOS when the computer is switched off. If the battery is weak or completely unloaded, BIOS will not be able to keep its structures. Another cause may be an incorrect or damaged BIOS chip.

There are ways to address this issue. First of all, a new CMOS battery should be replaced. The battery is a low-cost and easily accessible wrist. If the problem is not solved by replacing the battery, professional equipment that can diagnose and repair the computer should be referred to. It is also possible to try to update the BIOS until the last version, which can solve the problem of scattering. In any case, it is important to keep the Baekup of its BIOS lines on the outer carrier so that, in the event of a discharge, they can be restored quickly.

Reasons for BIOS discharge when computer is switched off

BIOS discharge may be caused by various reasons:

  • Nutritional problems: Unstable feeding or overstretching may lead to the discharge of BIOS. Overloading into the power grid, incorrect connection or failure of the power unit may cause such problems. It is recommended to check the state of the power unit and the computer connection.
  • Wages: Incorrect work on maternity fees can lead to the dumping of BIOS. Defects or incorrect connections of pay elements, such as BIOS batteries, may cause such problems. It is recommended that diagnostics and checking of fault fees be carried out.
  • Programme errors: The incorrect installation or updating of software, as well as the installation of incorrect parameters in BIOS, can lead to the discharge of BIOS when the computer is switched off. It is recommended that BIOS be rebuilt or software redesigned.
  • Viruses and malicious software: The existence of harmful software on a computer can cause BIOS discharge when off. Viruses can modify BIOS or cause other problems that lead to dumping. It is recommended that anti-virus checks and disposal of harmful software be carried out.

It is important to note that the discharge of BIOS when the computer is off is an unusual situation and may indicate serious computer problems. If such a problem arises regularly, it is recommended that a specialist be consulted to conduct diagnostics and solve the problem.

Electrical malfunctions

One of the reasons for dropping BIOS lines when the computer is off can be electrical failure. During computer operation, internal components receive power from the power source. However, with unforeseen disengagement, for example, through voltage pumping, overloading of the line or failure of the power supply, the uncorrected shutdown of the computer may occur. This could lead to the loss of data in BIOS and the dumping of it.

Several precautions should be taken to protect the computer from electrical failures. First, it is recommended to use a voltage stabilizer or uninterrupted power supply (BSI) that will provide continuous power supply to the computer even when the voltage or power cuts are down. It is also important to periodically review the state and the correctness of the power source and, if necessary, to replace it with a new one. In addition, it is not recommended that the computer be switched off dramatically, especially during the course of the hard drive or other important operations.

PreventionDecision
Use of a voltage stabilizer or EBSRecord the voltage stabilizer or the IBP and connect the computer to it
Testing of the power sourceCheck the state and the correctness of the power supply and replace it with new, if necessary
Careful release of the computerPhase out the computer, allowing time to close all processes and maintain data
