Hi All, I have a Powerbook A1106 my beast of a laptop, 1.5ghz PowerPC g4, 2gb RAM, 64mb ATI 9700 Graphics, 160gb HDD, Combo Drive..... But if i leave it unplugged overnight it won't turn on, i have to remove the battery (which only lasts 3 minutes) and hold the power button down, then insert the plug (without the battery) and boot up, then insert the battery.... bit annoying!!! I think it's the PRAM battery, i had a look when i was tightening the hinge screws and it's the PRAM board with the silver square battery... trying to find a replacement is like trying to find rocking horse *****. Can the original board be modded to take x2 or x1 silver button batteries? I'm good with a soldering iron so don't mind that, or does anyone know of any dealers that sell these? or will changing the main battery keep the thing alive when it's not plugged in? Thanks!! Gary.
