I once met a customer's machine, and the time always changed automatically, and I began to suspect that the motherboard battery was dead, so I replaced the battery, but it became the same again in less than a week, and the result was a short circuit in the motherboard battery, and the result was a new battery, and the power was exhausted in two days.

1. Check the BIOS settings;

2. Check the motherboard battery.

There are two reasons for this, one is that the motherboard's battery is dead, and the other is that there is a sudden power failure, resulting in a sudden loss of motherboard settings. Solution, keep pressing del when booting up, and enter the COMS settings. Go to the first item, change the flooy setting to disable, and then fold

Hello landlord!

It's because the CMOS battery is dead, the CMOS battery is dead, and every time you shut down the CMOS saved data is lost, it will let you go to set the BIOS after powering it on. Replace the battery on the motherboard. It's something like a coin.

If you don't indicate which hardware is the problem.

It would be nice to change the battery.

If there is a problem with the motherboard BIOS settings or the motherboard battery is dead, the solution is to turn on the computer and press Del or F1 to enter the BIOS, press F9, then press F10, and then press Y to save and exit.

Or select the option "Load Optimal Defaults", press Enter, select Y, and press Enter.

load optimal defaults is the default optimal setting, which is usually chosen.

If it doesn't work, you can only replace the motherboard battery.

Empty the motherboard, that is, touch the positive and negative stages of the battery, and then buy a new battery, go up and boot the BIOS, find the F2 option and select it as another option.

The CMOS date is not set.

Press the Delete key to enter the BIOS and set the date.

The setting is wrong, the time wood is set, press F2 to continue, press del to enter the setting.

It should be that the battery on the motherboard is out of power, and the replacement pool is solved, if the problem still appears after the replacement, it means that the motherboard is leaking, and the general repair shop cannot solve it, and it needs to be repaired.

The battery is dead, replace the battery, and then the BIOS factory settings.
