Im about to go to the Apple store for them to take a look at my MBP, It seems that the hinge is scarping the body of my MBP. But i was wondering since i installed a new HD, would it void my warranty?
It won't unless you break something while doing it. Apple even provides instructions how to do it. However, the self-installed HD is not covered by Apple so in case it goes bad, you have to deal with the seller/manufacturer of the drive
