Worst case, time to buy a new portable notebook. The 12" Powerbook was my favorite but Apple has stopped PowerPC support now.

Best case, connection problem. Turn off the machine, unplug the AC Adapter. Using a q-tip or a small cloth, wipe both connections clean (notebook and the adapter plug). No need to use water or rubbing alcohol. It may or may not work. Good luck!

hi thanks ive tried it but with no luck still nothing, if it isnt the mains plug or adaptor what could it be, the powerbook was still working until the battery ran out, just hope it is repairable. thanks

hate to say it .. but if you did try another power supply could be your dc input board.. and this is a bugger to get too on the powerbooks..

Here is a link to ifixit

have you tried the basics ...
To reset the PRAM, hold Apple-Option-P-R simultaneously at the Apple logo.
To reset the PMU, hold down “Shift-Control-Option-Power “.

other than that ... it does not look good..
