With the motherboard removed, you are finally ready to remove the battery compartment and change the battery.

Using your Phillips #2 screwdriver, remove the four front screws.

Keep these screws separate, as they do not match screws used in other steps. However, all 10 screws securing the battery compartment can be freely mixed and matched as they are identical.

The front screws are very near edges and, depending on the thickness and length of your screwdriver, might not be accessible with a conventional screwdriver.

If you are having trouble with a conventional screwdriver, use your right angle screwdriver. It takes longer and is more difficult, but if you strip these screws, you could be locked out of the battery compartment forever. You do not have the angles or leverage to use proper screw extractors.
