Just got a PB 1400cs/133, G3-upgraded (Sonnet Crescendo) running 8.5, purchased on ebay. Here's what it's doing:
The first couple of times I booted it up, everything was fine. But soon enough, each time it boots up, shortly after it reaches the first "Mac OS" splash screen, the screen gets very dark - so dark you can barely see the rest of the boot-up, icon parade etc. When it gets to the desktop the screen goes completely black, but it *sounds* like the boot-up completed normally.
After being distressed for a few minutes, I tried booting it from a CD - to wit a Norton Utilites CD with a (presumably) cut-down version of 7.6.1 on it. Everything was just fine with no video problems. Then I decided maybe there was some software problem and I should do a clean install of 8.5 & 8.6. But as soon as I booted from the OS 8.5 installer CD the exact same video problem came back! Went to bed frustrated last night.
Woke up this morning having "slept on it" and realized this video problem reminds me of what a dead PRAM battery might do to one of my desktop macs. Maybe I have a dying PRAM battery, but the older smaller OS on the Norton disk just used slightly less juice and was able to boot up??
Can't work on this any more until after work tonight, but in the meantime it would be a real help if somebody with more experience with Powerbook PRAM batteries can either confirm or deny my suspicions about these symptoms.
Thanks in advance for any help!
