how to install a c-mos battery in a dell latitude c-840 Laptop


Hello,

this means you will be opening the laptop cover from under, then remove the old c-mos battery, then replace with another.

The laptop must be off, battery removed, unscrew the under laptop cover, to access the c-mos battery, and that's all.

Good luck.

How do i remove power on pass word? IBM T23 thinkpad


try removing the C-MOS battery, you will need to take the laptop apart, the battery (s) are located at the front right and should be in a plastic either blue or yellow sleeve, they will look like watch batteries or if you have ever owned a laser pointer they will look like those, small round about 1/4' diameter and there should be 3 of them, disconnect the wire for about 30 min then reconnect and that should fix the issue
