Replace a swollen, old battery

Mijn probleem

The old battery had swollen enough to push on the trackpad.

Mijn oplossing

The repair went exactly as advertised!

Mijn advies

Because the old battery was swollen, it pushed against the bottom case panel with enough force to throw the tiny screws some distance as I loosened them! If your old battery is swollen, take care to apply some pressure to the bottom panel and contain the screw you're removing until you've completely removed the screw.
