In all likelihood the problem is that your battery isn't holding a charge
and all you are feeding it is power off the adapter. The Mac Portable power
adapter (which is in actuality more of a batter charger than it is an
adapter) does not put out enough power (only 1.5a at 7.5v I believe) to spin
up the hard drive or fully power the display. The best solution is to find
a Powerbook 100 adapter which puts out the same amount of current (2.0a) as
the portable battery is designed to (presumably this is because the PB100 is
essentially a reworked Mac Portable). I have also used a PB170 adapter
(model M5652) with success, but it puts out 3.0a and so you're running a bit

A PB100 adapter is currently up for auction on e-pay: They are
hard to come by, BTW.
