[QUOTE="dtravis7, post: 1390310, member: 8287"] As I am sure you know, they use a switching power supply. Seen some that whined like that eventually go BANG! :D I had a couple in towers spit fire out the back of the fan vents! If it does go, it could hurt the MBP. Might not, but just telling you what I have ran into in the past with repairing computers. I had one 300 watt PS that did the fire out the back. Motherboard was blown, controller board on hard drive was blown, one optical drive no longer worked! Not trying to scare you with all this. The whining usually is from the colis/transformers in those switching supplies. Had one do it and the main electrolytic cap was bulging out the top with juice coming out. [/QUOTE]
