Kicked the power cord and thanks to the non-mag-release cord, the computer failed to charge when plugged in. Using a multi-meter, it was determined that the power supply was functioning properly but the DC-in board was not.
Removing the plastic shell from the laptop was by far the most difficult step. Carefully working around the edge, prying outwards as I went, the case was often reluctant to release from the rest of the shell. I broke one clip above the CD drive where the plastic was at its thinnest. Replacing the shell was very easy; a snap, even.
Removing the shell should be done slowly and carefully. As the plastic ages, it will become more brittle. This is problematic, as I had to bend the plastic outwards more than I was comfortable with. You might find it helpful to heat the shell with a blow-dryer to help alleviate this some. Be careful over the CD drive, the locks for the shell here are very thin and fragile.
Don't tell girlfriend's mom about fixing the girlfriend's old computer for $33 if the old computer has already been replaced with a new $1600 computer.
