Hello, Every time I close the lid of my MBP 2.2, it goes to sleep and will not wake up (the light pulsates and the screen is black, but it doesn't wake up when opened or with keyboard). I just upgraded from 10.4.11 -> 10.5.1. I've installed all of the software updates. This happens every single time - without fail, even if I'm running no applications. This is really awful. Not only do I have to manually shut down, but then it takes about 3-4x longer to boot after a crash. My job requires frequent moving around, sleeping/waking up of my computer, so this is an absolute deal breaker. Having my computer crash every hour is going to really screw me. Any help is extremely appreciated. EDIT: The light sometimes is steady and doesn't pulsate when it goes to sleep, but same result. EDIT 2: I decided to do a cold installation from my external firewire drive, and now it's not reading the drive! I go to System Profiler and under "Firewire" it says that there are no devices on the bus! It doesn't even read that there are any ports there! This feels like Windows XP before SP1.
