Okay, my PowerBook G3 Pismo was in the middle of the 10.1 update, after a reinstall of OS 9, OS X. Unknown to me was my power supply had died, so it was running off battery. While at work, letting the update go, I looked over to see it in sleep mode, black screen, power light slowly fading in and out. I quickly try to diagnose the problem, and find out the fate of the power supply.
After a trip to Frys, and a new 3rd party power supply purchase (they were out of the stock apple yo-yo ones for my old PowerBook), I plug my laptop back in, and bring it out of sleep mode. Now I was expecting to find all kinds of errors spew forth, or a nice core dump, or the need to reinstall it all again. But no, it read '7 minutes left'. Which then turned into 47 hours left, and I saw the minutes fly off, and it took about 14 more minutes, and it was done.
So far, I have not experienced any problems after this, and I just have to take my hat off to Apple.
