Recently I've noticed that my MBP will suddenly show as being on battery power, even though I'm plugged in. Or, at least I think I'm plugged in. Upon closer inspection, I can see that the light on the adapter isn't providing that friendly green or amber glow, even though it appears to be securely nestled into the power port on the MBP. Turns out that there are 5 little prongs inside the adapter, each of which is apparently supposed to be equipped with some sort of backer spring which keeps a tight connection between the adapter and the power port. On mine, two of those prongs fail to bounce back and as a result, I'm not getting a good connection to the power port. I can "shake" the adapter end to get the plugs to come out to their normal position: But once I hook it up to my MBP, the ports are pushed back and don't pop back out: Sorry for the somewhat lame pictures, but the iSight won't focus much closer in than this. Anyone else having this problem? I searched here and couldn't find anything. I'm going to head over to our IT department to see if they have any spare adapters, but I'm guessing they're going to need to exchange this one somehow. I'm concerned I'll damage the power port if I keep trying to force a connection.
