What to do??? My MBP Core Duo is about 8 months old now and there's a faint, annoyingly high pitched squeal/squeak coming from where the MagSafe power supply connects into the MBP. When I disconnect the power, the noise ceases (and all is right in the world), but when reconnected, the noise comes back. I feel like I'm taking crazy pills!! What should I do??? As a side note, the fans are not related to this problem. And sometimes when I run an intensive program, the whine stops. (PS - this is the 2nd thread I've started on this cos I now know it's not the battery but the MagSafe itself. So I needed a new title.) Can anybody help me??
