Does it charge the battery? Other thing to check:
An Apple Service told me to remove the batteries (from Expansion Bay and the PRAM Battery. Now, without the AC Adaptor (without any kind of energy), press "Command - Control - Start button" for a minute. If you find a little "reset" button on the main board, push it instead of the keys. Also push the little reset button behind the PowerBook (near the connectors at back) Leave the PowerBook one hour like that (without energy at all). Then, put the PRAM Battery again and plug the AC Adapter. Check if Starts. You don't have nothing to loose. Here's a link to find the PRAM Battery if you don't know where is located: http://www.pbfixit.com/Guide/man.php?p=Pismo*00 I have my fingers crossed. PS: Sometimes the Motherboard hangs and doing this, the board can be fixed. If this is the case. --- Adam Thayer <[EMAIL PROTECTED]> wrote: > > On Jul 30, 2004, at 1:42 PM, Alejandro wrote: > > > Check this. > > With powerbook attached to the AC Adapter (no > > battery), press the start button, and you should > hear > > a little "contact" sound at the same time the > Start > > button is pressed (before the Startup sound). > > If you don't maybe the machine is not powered at > all. > > You are right in that the machine is not getting > power to where it > needs to go. > However, it doesn't seem like the Battery Board, and > since power is not > getting anywhere (entire machine is cold after > pressing the power > button), that would leave the logic board, correct? > What I am trying to > do is figure out what components would cause the > Pismo to remain cold > dead with both a fully charged battery, and an AC > power source. > > >> First and easiest thing to check is the RAM.
