Changing the CMOS battery on a Dell Latitude D820 is a lot easier than a lot of other laptops that I've seen and in this video not only will I show you where it is and how to change it I will also show you how to make your own rather than having to buy one off of eBay!
To make your own battery you will need the following items:
- CR2032 Button Cell Coin Battery
- Conductive Tape
- Heatshrink Tubing
- Heat Gun (a soldering iron up close will do if you dont have a proper heat gun)
Appologies for the bad jokes (there aren't many) - #thatswhatshesaid
