Recently, my laptop always shows the wrong time to start, which I always have to correct. What can that be?
I have a laptop with Windows 7.
Change the time zone in the BIOS / UEFI.
The bios battery may be empty. You would have to replace it. A button battery costs about 1-2 euro
Either the time zone is set incorrectly in the bios or your bios / cmos battery is empty.
