Just got off the phone with AppleCare. Amongst other things, I asked if installing a new HDD in a laptop voids the warranty. He said that I have to have Apple or an Apple-certified technician perform the HDD swap to maintain the warranty on the laptop itself. He also said the new drive would not be covered, which I understand. But I thought HDD replacement by the user would NOT void the warranty over the rest of the laptop. I've read it on several message boards. Is there something about new Macbooks? Did the policy recently change? I don't want to void any warranties, but I also trust myself to be more careful than someone at the Apple store/Genius bar. I just want to do it myself. Any comments or experiences with this situation?
