The Toshiba 1200 uses Toshiba AC Adapter Model PA7485U,
which is 12V, 2.2A, center positive. The back of the
computer says "12V" at the jack.

If your 12V, 1.5A adapter (which is likely +centered,
otherwise you wouldn't get the LED lighting up) is
insufficient to power the machine with a dead battery,
you might get the behavior you describe. Try letting
the battery charge overnight, or get a beefier supply.
