The laptop thing definitely sounds like a power issue. Re the actual controls 'sticking' if you mean they get stuck and won't respond then its probably the encoder so the I-Pac should solve the problem. If you mean they don't respond quickly enough then it could still be the encoder or it could be buttons and switches they use aren't up to much. Worth checking when you open it up that none of the swtiches are bent and failing to make good contact.
