Hi all, my Powerbook G4 1.33 with 1.25 Gb ram is running really hot. I know this is common. However, even with Energy Saver preferences turned down (Put hard disk to sleep whenever possible and Processor speed on *reduced*) and with minimal usage (Word, Mail - and I've checked, the CPU is only under normal load, mostly around 15-30%) the fans turn on within about 5 minutes, and just get louder from there. This is a two-year-old (almost) computer, and I've never had it this bad. I've checked the forums and they're all people saying that heat is normal for a powerbook, which I realize, but I really don't think it should be this bad. Could a vent be blocked or something? If so, what should I take apart or do? Thanks very much in advance.
