Solved Post Error. System Boot Problems

December 7, 2014 at 18:58:50
Specs: Fedora, Pentium(R) Dual-Core 2.50Ghz
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.

If you have the jumper in the clrCMOS position (usually 2&3) and have run the computer you are lucky you haven't damaged anything.

Verify you are placing the jumper in the run position, not the clear position. You also need to perform that operation with not power to the motherboard. So, if your PSU has an on/off switch use that to interrupt the AC power or unplug the computer from the mains.

Post a full model for the computer or motherboard.

eMachines EL1700
Intel Pentium Dual-core CPU
E5200 @ 2.50 GHz 1024MB

I have booted up my computer while the jumper was still on the clrCMOS and I have installed on it a fedora OS..But now I put back the jumper on the pins 1 and 2..but the Post errors are still showing. The unusual part is..it only happens if i completely shutdown the computer..but if I restart the computer it wont show the error..

i've been following some same issues and forums regarding with my problem and tried some solutions..the one i have not tried yet is changing the battery..

what would you recommend sir?

What prompted you to clear the cmos? If your settings weren't holding then you probably also need to install a new cmos battery.

My grandpa wore a fedora (yeah, I know. . . linux but 'installed a fedora to my computer' sounds like you set a hat on top of your monitor).

I just want to complete it without errors.. I feel responsible for my mistake thats why im ashamed to asked my prof because i think he might get angry(or he will)..so I came here to ask for your help guys..

Maybe leaving the jumper in clear position for so long drained the battery. I'd go ahead and replace it--they're only a few dollars at radio shack or similar shop--and see if that works out.

The battery is likely about the size and shape of a nickel coin. Make sure you don't bend the prong holding it in when you remove the old one and make sure you get the polarity (+/- orientation) correct when installing a new one.
