When I close the lid of my PowerBook it wont wake up when I open the cover no matter what button I pres. I have to disconnect the charger, remove the battery for a while and when I replace it, it boots up fine. NB My board battery is dead and not keeping the time and date up to date, and my notebook main battery is also us. many thanks Stephen

Hi, You need to replace your PRAM battery and then do a PRAM reset. Ralph

hi. i have a similar problem. laptop was working fine, then froze. i force restarted holding the power button and it made the chime but never came back on. i havent been able to start it since.
if left alone it will drain the battery very fast. the part above the keyboard feels warm even though the machine isnt on. if i plug it in, it will charge the battery and the light will be amber, but if i press the power button the light will switch to green for a few seconds, then back to amber.
does this sound like i need a new pram battery or is it something else? thanks
