PROBLEM: Review: I bought this plug as a substitute to replace the Apple one that blew out. Unfortunately, this plug seems to have problems. I noticed that it heats up really badly when plugged into some plug outlets and causes my laptop to heat up as well. Once, I also heard some noise coming from my iBook G4 that wasn't there before. This noise went away when I unplugged the power cord. What I'm most upset about though is that it seems to have shortened the battery life of my computer to about 50% now! I think I should have bought the Apple plug instead.
