Solution 5 – Check your computer battery

If the clock on Windows 10 is wrong, you might want to check your computer battery.

Time and date settings are stored in BIOS, so if your battery is corrupted BIOS won’t be able to properly store the time and date settings thus causing your clock to show incorrect time in Windows 10.

The simplest way to check if your battery is working is to enter BIOS and check the clock from there.

To Enter BIOS, you’ll have to press Del or F2 while your computer boots. Some motherboards use different key to access BIOS, so you might want to check your motherboard manual for more information.

If the clock in BIOS is correct, your battery is working properly and there’s no need to replace it. If the clock in BIOS isn’t showing the correct time, you should replace your computer battery.

Replacing your computer battery is rather simple, but you need to make sure to get a battery with same characteristics in order to avoid causing any damage to your computer.

If you don’t know how to perform this process, please contact an expert.
