new to the forum here, and i too have been having power issues with my ibook g4. the power issues started similar to what others have described (intermittent power, no charging) so i bought a second AC wall adapter. things worked well for a few weeks, then the problems appeared again
as of now, i can't get the thing to take a charge or power up at all (the battery is completley dead). i thought i needed a new DC power in board, untill i stumbled onto this thread. i REALLY want to try the two resets recommended, but the battery is completley dead and i'm not sure if the resets will work with no power (dosent seem like it would). i'm hopeful that a PMU rest will work (so i dont have to shell out $250+ for a new DC in)
will a PMU reset work on a "dead" battery? is there anyway i can verify that the reset happened?
The other day I turned on my ibook g4, but it wouldn't start. I can't figure out what wrong...
but I do know that:
1. The battery works
2. the power is ok
3. the harddrive is new and should be working. I replaced myself 5 months ago.
When I start the mac, tha machine makes the sound it usually makes when it starts up. I'm thinking of the apple sound of the OS, but the sound machine. Then i can hear the harddrive starts - i think its turning or something. I can see the monitor is turning on because the shade of black not the same.
When I press on the computer just above the harddisc the fan starts, and then I can turn off the ibook by pressing the start button for 5 seconds - which i couldn't before.
Can I reset my PRAM/PMU on a G3 ibook using these fixes?
Mine is actually a G3 ibook (not G4) and I have already tried reseting these using the listed fixes at the beginning of this thread with no luck. I cannot get the ibook to power up, worked fine yesterday until the wife shut down power...will not power up now. Any suggestions are appreciated.
If these don't work, what is the recommended next steps...Apple store repair, etc.??
Hello,
I have a G4 and hyper fingers. Is there any way through system prefs (I've tried looking in individual program prefs) to have there be a "warning: do you really want to exit? yes/no" box pop up if I accidentally quit with six windows open in Safari? This is mainly the place where I have the problem. It just seems like an issue that Mac would anticipate and make provision for, so I thought I'd ask. Any help would be much appreciated. Thanks.
bought iBook G4 in mid 2005 (14")
Sent it back because it kept shutting off
got a new one that August.
Got a new logic board Sep 2006.
November 2007 - computer started to randomly shut off. I took it in to get it looked at last week and the guy put a screw back in to my central power and held the power switch for 10 seconds and all was well.
Now I SWEAR that I did everything in my power to get the computer to turn on with no luck. I did the PRAM and PMU stuff both with and without the battery. I pressed to the left of the trackpad. You name it, I did it.
Well, today - now it won't turn on again. I had left the computer open when the battery was in the red. I turned around and it was black and nothing would turn on. So I plugged it in, waited about 30 minutes and still nothing. The battery is brand new. It says it's charged, and my charger was working today. My battery was also working. I've tried the PMU and the PRAM commands, with and with out the battery....
what could be my issue? Or do I just need to call someone.
Help. New Mac Air going wrong! Worked fine until I ran an update, restarted it and it keeps taking me through the set up assistant over and over again!
Mac Specs: 16GB Black iPhone 3G | 13" Black Macbook 2.2GHz, 4GB RAM, 200GB HD @ 7200rpm
small problem
i shut the lid of my laptop and left for a few hours and kept it plugged in. when i got back it was fully charged, unplugged it, and opened the laptop and it didnt wake up, i clicked some buttons and eventually just restarted it. when it turned on the built in webcam turned on and is green. i opened photobooth to see if i could turn it off there but i cant, and no picture shows up in photobooth either, just black...
tried restarting it again, but the camera stayed green the entire reboot and still shows no picture in photobooth.
