Has any come across a solution to this? My family has a couple Inspiron 9400's and Inspiron 1525's. We recently rebuilt them all (by putting in new hard drives and installing new copies of Windows 7 on them). ALL of them now have the problem above - they won't charge, yet ALL of them worked before.
One of them was done remotely (in another city) so it wasn't a power spike that killed them all, it was doing a new installation.
Also, on one, if we put the old HD in and boot with it - magically it charges no problem.
So if anyone knows how I messed up by installing from scratch I'd really appreciate to know the trick.
