Solved Post Error. System Boot Problems

  • 0

I have reset my cmos in a wrong way. I place the jumper in pins 3 & 2 and boot it up then installed a fedora to my computer.. now everytime i boot my computer post error occurs saying
“CMOS Checksum Bad”
“CMOS Date/Time Not Set”
“Press F1 to Run Set up”
Yet if i press F1 and load the defaults then Save and exit..automatically after restart..the Post errors does not show anymore.. But after properly shutdown..when i boot it again the Post Error occurs…

Any help would be appreciated..

      You posted while I was composing mine. When you configure the cmos and then reboot it does a warm reboot, that is power is never completely off. Thus the cmos settings remain even if the battery is bad. But if you do a complete shutdown, having a bad battery can cause those settings to be lost. So barring other hardware problems, a bad cmos battery is most likely the problem.
