Late last week I was shocked to find that my trusty Titanium PowerBook had gone to sleep and wouldn't wake up. When I tried to reboot it, it hung early in the boot process. When I booted in verbose mode (hold down Command-V right after turning it on) to get more info, it stopped while still in the power-on self test (POST). Ugh. Resetting parameter RAM and reset-all in Open Firmware didn't change anything. To my great relief, I was able to get the computer to come up in FireWire Target Disk mode, and the hard disk seemed fine (I backed it up at that point, of course).
I quested off to meet the Genius at my local Apple store, who quickly concurred that it looked like a main logic board gone blooey, which would cost me about $300 and a week without the PowerBook while it visited the repair spa. As I pondered my luck (out $300, but data intact), I compared my situation to that of my fellow Genius Bar patron, a young woman whose cat had tipped over a vase full of water onto her nearly-new powered-on iBook. She faced a repair bill of > $1000 and an unknown fate for her hard disk. Bad kitty.
The Genius said my PowerBook would be in the hospital for a week to 10 days. It came back yesterday after only 48 hours! (That's called "under-promise and over-deliver".) I picked it up and verified that it worked again, with its new main logic board. I looked at the Parts Used list, which included this inscrutable entry:
810-1703 BZL,ALUM,PNT
Yes, the Apple repair tech had
touched up the paint scratches on the case. No charge. Cool.
Very good things: FireWire Target Disk mode, Apple repair service, Apple store.
Lucky thing: hard disk surviving dead main logic board.
Bad thing: cat.
Lesson learned: back up your data!
