Hi. I'm not sure if this belongs in this forum or not but I have a Lenovo G580. It came with Windows 8 and I downgraded it to Windows 7. I had to make obvious BIOS changes in order for this to happen because they were default to Windows 8. The issue I am having is when the battery dies or is removed (power discharged) the BIOS resets making Windows 7 boot impossible unless making those necessary changes. I have changed the CMOS battery and the BIOS is updated to the latest version.  Lenovo support is no help so I am at a loss.

Sounds like a CMOS battery issue.  You may try replacing the CMOS battery again, perhaps there was problem with the one that you used.

Is the Time and Date going to some default values aswell? If so it has to be the CMOS battery, since everything is going back to defaults.

 

Maybe you damaged the battery's dock by accident?
