I was recently given an old Toshiba laptop. The battery is dead but, at first, I could turn it on when plugged in.

Then I left it unplugged in for a few months. Now, when I turn it on, I get this error message:


**** Bad Check Sum (CMOS) ****

Check Systems. Then press [F1] key.


I have no idea what to do?????

Thanx Many!

There is also a small, coin-size CMOS battery that needs replaced
It is usually underneath the keyboard or behind one of the access panels on the bottom

garmanma,

Thanx much for your help.

A question: you said "there is "also" a..........." Also? Did I miss something somewhere? Was there another reply or suggestion?

Pardon my ignorance.....I'm new at this and a little confused. Just wanna make sure I don't miss something. Is it pretty clear to you that replacing the CMOS battery will fix the problem?

Thanx!!!!!!

I didn't want you to confuse a system board battery to the laptop battery
