NOTICE: The tabs on the release button are plastic. When squeezing the tabs,
be careful not to break them.
On the inside of the bottom case, use needle-nose pliers to gently
squeeze the two release-button tabs together and push the tabs down
through the hole, catching the release button on the outside of the
bottom case.
To remove the battery latch, unhook the small tension spring located
on the metal post next to the hard drive.
With the inside of the bottom case facing up, place the battery latch
in position.
Turn the bottom case over and align the slot in the battery latch with
the release-button slot in the bottom case.
Holding the battery latch in place, press the release-button tabs
through the underside of the bottom case and into the battery latch
until the tabs snap into place.
