Solved cmos not holding memory even after new battery is installed

  • 5

I have a Win 7 Gateway LX6820 desktop computer. I’m getting a checksum error when I boot. I replaced the battery on the motherboard after first unplugging the computer. I then rebooted and corrected the date and time, loaded and saved the factory CMOS defaults, and the computer starts fine. However, if I turn it off and switch off the power strip, the CMOS memory is lost and I must repeat the process. I’ve checked the battery. Any ideas? Thanks.

      The negative contact in the battery socket may not be making contact. bend it to correct.

      You could also check with Gateway to see if there is a BIOS update to address this problem.

      Unless the computer has been subjected to a power surge I can’t understand why this should be occurring.

      Below is a link to Gateway downloads. It appears there may be some BIOS updates. The latest one gives no reason for the update. Be aware that flashing the BIOS MAY result in a non operational computer.
