I've seen this twice and fixed it more by accident than by intent. In
one case, I left the battery out of the laptop, and no charger plugged
in, for about a weekend. When I returned on Monday, everything
magically worked normally. In the 2nd case, I was trying various
combinations of starting the computer, with the battery, without the
battery, with both, etc. At one point, it magically started working.
That was about 1-2 years ago, and both customers are still using the
laptops.
However, I have another Toshiblah laptop in the office with similar
(not identical) problems, that I can't fix. It also won't charge the
battery, although it will run on battery if I charge it in another
laptop. The problem was traced to a crappy BGA soldering job on the
video chip. Try booting from battery in Safe Mode, and then plug in
the charger. If that works, then it's probable that you have a video
chip soldering problem. (I'm debating the merits of buying an
overpriced hot air rework station. I borrowed one, liked it, but had
to return it).
Please do not tinker with external power supplies unless you're
absolutely sure you're using the correct power plug, and the correct
voltage. I've seen what's left of the laptop when the clip leads get
swapped, or the power supply mysteriously got to maximum. It's not
pretty. The correct power supply is 19v 3.4A negative ground,
5.5/2.5/12mm connector.
