MacBook Pro 13" Unibody Mid 2009 Teardown
> When working on all machines that have internal batteries, disconnect the battery first to cut off power to the entire device.
Do you mean I have to remove the battery before to unplug the magsafe plug, cutting out power?
This means I had to remove the back cover with MacBook shutted off but powered.
Has the MacBook Pro 13.3" a backup battery?
Ps: nice teardown!
