Since I'm the "go-to-guy" for all things technical at my school, I get everyones bum PCs to fix. Here's the latest.
Canon Innova Book 350CD
100Mhz 5x86 CPU
8MB of RAM
Passive color VGA display
Swappable drive bay
It won't turn on while plugged in. Only from the battery. Once it's booting I can plug it in and it runs off that while it charges the 12V battery. I do get a CMOS error each time I boot it.
So far I've disassembled it completely and all I can find wrong appearance-wise is a crusty discharge from the CMOS battery. I've removed it and cleaned the board of the discharge.
The laptop does have an independent power supply board, but it looks fine. My only other thought is that the fuse near the AC plug is blown, unfortunately it's got a chunk of aluminum around the center, so I can't see for sure if thats the problem.
