G3 pismo won't start up

by monkeyandsofia / February 4, 2010 5:17 PM PST

Hi, my G3 laptop has been in storage for over six months and won't start up. The power lead and clock battery are new. This happened before and Dianne the moderator at the time gave me a simple keystroke sequence to bring it back to life. Anyone out there know what that was?

Apple + Option + P + R at the first chime. Hold until the second or third chime.


Apple + Option + O + F and then, when you see the "to continue booting" message, type reset-nvram, press return and at the next prompt type reset-all, press return.

Let us know which, if any, worked

thanks for getting back. I tried your two suggestions but nothing happens. No sign of life whatsoever, totally black screen and not even a chime.

Simultaneously press Shift-Fn (function)-Ctrl (control)-Power.
Wait 5 seconds.
Press the Power button to restart the PowerBook computer.


If your machine has a reset button the back of it.
Restart the computer by holding down the reset button to the left of the Serial port for 10 to 20 seconds.
If the computer does not restart, repeat step 2 three or four times.

hi,no luck. Is the internal battery rechargeable? If so, should I leave it plugged in for a while, then try again? Or any other suggestions. Anyone? This must have happened loads of times to people. Who else out there has gone through this?

with some time on charge and the keystrokes you suggested, we now have life restored. Sadly not for much longer as the screen has gone yellow, unless there is some miracle cure for ageing lcd screens?

that may not be a screen problem.

it could be a Graphics controller problem.

Yellow and red shifts

Are pretty well known signs of old CCFL tubes. I have a picture of the red shift at

The picture was not made for clarity or focus. Just to show that CCFL tubes do shift color over time. If you continue to use the CCFL it may change color over time. If it is the CCFL tubes those are replaceable but can be costly if you don't DIY. BEWARE THERE ARE LETHAL VOLTAGES DRIVING THE CCFL.

I?m afraid you?ve both gone beyond my technical ability. I replaced the memory and HD last year, is this any harder? What is it I should be looking for to replace?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
