I've got a difficult problem with a Lombard PowerBook. Basically, it powers up and shuts down right away. I've tried it with 2 different adapters and with/without battery. I've also reset the Power Manager on it. Doesn't turn on at all if no adapter is plugged in.
To sum up, when I plug in the power adapter, the computer starts to power up and then immediately shuts off, then repeats until it is unplugged.
Any ideas?
