BIOS checksum error on an old computer might be just a dead battery for it right?

I always assumed the standard Windows sleep was just a regular old sleep, storing system memory in RAM and runs on very low power for quick retrieval when you start it back up, unlike hibernation which writes it to the disk so tat no power is required, but which also takes longer to retrieve. Perhaps Windows is using a hybrid sleep mode and doing both; sleep for short periods, hibernate if it goes on longer? Not sure but it must have written it to the disk or it would have been lost. I will look into my BIOS settings. I am not sure why they would have changed and I would have thought that restoring the BIOS backup the first time would have fixed anything that may have been an issue but apparently not. thanks

If you haven't changed then yes that's exactly what it's doing. You need to tell your bios when and how it's supposed to wake up.
