Bios error message! [Solved/Closed]

When I turn on my computer, before booting, I encounter an error message that says:

CMOS/GPNV checksum bad
Press <F4> to run setup

I haven't updated my bios and I don't remember changing any bios settings. I have also loaded optimal defaults in the bios setup but that also does not work. I also removed the CMOS battery and replaced after waiting for some time, clearing bios memory and loading the optimal defaults. But none of those ideas work. I don't see this error message when I restart my computer, but only when I turn off and turn on again ( even immediately).

This is not really a problem, because when I press F4 and in the bios screen if I press Esc without changing any settings, the computer boots normally. But I fear that this problem may render my computer unusuable if it continues to pop up.
Thank you.

Thank you
Hi there,

Change your bios battery then press on F1 to run setup save and exit bios settings it will be fixed.

Thank you
Thank you very much for replying. But if I don't change the battery, will it have any negative impact, I mean, will my computer continue to run even if I don't change the bios battery?
Thanks again.
