My 85 W PA suddenly died on me and is not working. I am so frustrated and so I tried to use my husband's 60W Magsafe PW and it seemed to be working. The only thing that worries me is that the Power adapter gets so hot while I am charging. Should I be worried, is this normal, is it safe to use this on a 15 inch MBP ? Many thanks in advance. I hope to hear from someone who could help me out. I would truly appreciate it as I always do.
