CMOS Checksum bad - bios flash?

by kaan921 / October 27, 2012 4:08 AM PDT

After I flashed BIOS with WinDPtool that was in the BIOS folder, I restarted the computer, then I got this error: CMOS Checksum bad - Press f1 to run setup.

I bought new CMOS Batteries to my computer and replaced it with the old one, but it doesnt seem to work. The BIOS wont save when I choose "No errors" on Halt on in BIOS CMOS Features... so, my questin is kinda gently; how do i fix it? Happy

i set the correct time and date, and that is saving.. not the other options in bios Sad

i got an acer veriton m670g computer and installed the p03 bios, and the p04 is the latest.. i cant boot from cd due to bios is doesn't let me first boot thingie

That's not a Windows issue.

This machine needs repairs. I think that most users today can't boot from floppy or may not want to learn how.

I suggest you arrange with Acer for repair.

I can't boot from floppy or cd due to i can't change 1st boot device, since bios is not saving.

Acer wants money for repairing this.

Can't boot from other devices means we can't fix this one. Sorry but other ideas are to place a small DOS formatted HDD with the new BIOS and utilities on the machine but I hope I won't upset you that I can't detail this any more than this. You must be able to pull this off.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
