Someone gave me a Gateway laptop to fix for them.  Based on the symptoms of the problem, it made sense to test the power supply's voltage.  I'm talking about the brick on the AC charging cable.

I plug it in, it outputs 19v DC (which matches the rating printed on the brick).  I unplug it and voltage goes to 4v, back up to 18v, 6v, 15v, then finally to 5v and then slowly dissipates to 0v...all while unplugged.  The fluctuation from 19v to 5v is maybe over seven seconds or so, then it takes a full 45 seconds to dissipate to 0v.

I feel like this is the problem, but I'd like someone to back me up first.  The model number of the power supply is PA-1650-02.

I have a Gateway laptop that has a power supply that fluctuates from 19v to 5v
