    It's a Rev. A 15" Aluminum Powerbook... and it's been pretty much dead for a year.

    Here's it's story: It worked fine and dandy for like 2.5 years with only the white spot problem early in it's life. Gradually over time the machine slowed down (stock 256 mb ram...) and I added more ram, which drastically increased the performace.

    Then it slowly started to die on me. It would randomly upon startup get stuck on the grey screen with a small finder icon/face thing in the middle blinking with a question mark. This grew more frequent until it finally did it EVERY SINGLE TIME. I did some poking around with the install disk and it couldn't seem to find the hard drive. It wasn't even an option in disk utility. I know! the hard drive must have died! So I replaced the hard drive myself (I didn't get applecare... d'oh!) and it worked fine and dandy... for a few weeks. Then the same problems began to appear (the weird thing on startup, not finding the harddrive...) and conveniently the macbook came out so I snatched it up on the 2nd day it was out. My powerbook has been collecting dust in it's terrible state ever since.

    So, it's summer, I'm bored... I try out the ole powerbook and... it's still doing the same thing. I put in the startup disk, mess around, it still doesn't recognize that I harddrive exists. Strange. I continue messing around and somehow get to Apple Hardware Test or something like that... and run a test on the system. It appears to check the function of all significant parts (Motherboard, RAM, Hard Drive, combo drive, graphics card, airport). I run it. according to the test (I ran it several times), NOTHING is wrong with my computer... everything checks out as "good."

    I don't have much Mac experience, but I do have electrical experience.

    It sounds to me as though you have a short in or around the connector used to hook-in the hard drive.

    Can anyone else think of an explanation for the diagnostic discrepancy? Do Apple's utilities utilize service-level and diagnostic switches at the hardware level?
