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.

You can remove or change the Window's User or administrator's password. You need access to a computer with Internet access to download the Hiren's Boot CD and burn it onto a CD. Then insert this CD into the laptop/computer and boot up the laptop/computer with the Hiren's CD and follow the instructions. There are very useful utilities CD and it a Linux boot CD which contains quite a lot of Utility programs including a password removal program.

Module Bay


The D610 second battery is installed in the slot occupied by the CD Rom.
This is an additional omponent that can be purchased to extend the battery life for the laptop.

Unless you have this battery module installed the error is completely normal.

Re: dell laptop


Hi

Any Dell XP disc will reinstall the system back to XP. You will need to download the system board drivers from the Dell Support site after you have installed XP.

Borrow a any Dell disc from someone, it will work
