Bios Clock changes everytime it's restarted

[noname896]

Hi Everyone,

I have tried to find a final solution on several posts with similar questions.

I have dual boot, I don't have any issue with the time on both OS (MacOs,W10) I have fixed them both to show the proper time.

But the problem is the BIOS clock it shows a wrong time/date once it boots. I have tried to schedule auto turn on on my hackintosh but it just won't work because of this issue.

Could you please let me know what I do.

Please let me know what information do you need from me.

If your using OpenCore try
Kernal/Quirks/DisableRtcChecksum=True. in config.plist

Thanks for your reply, I'm using Clover is there any equivalent parameter?

Check and if necessary replace the CMOS battery on the motherboard. If the bios is not holding the time correctly after a restart it could be the battery is failing.
