Have you tried the PMU reset tip mentioned on the first page here?
The little gray button is the battery charge indicator. It is actually part of the battery, not the iBook itself and is handy if you want to check the battery's charge when it isn't plugged in to your iBook.
I'm new here but running out of ideas with my IBook G4 (OSX 10.3.9) 9.33 MHz.
I just restored it to original settings and software as it was full of 3 years worth of junk and everything was fine until I tried loading a few important things on it afterwards.
The CD rom drive would not eject the disc initially finally I managed to get it out and now it will not accept a disc into the drive?
I just bought a second hand PowerPC Aluminium 1.67ghz/512/120gb with bluetooth and all the whistles. However, upon getting home and plugging it in, I get a rapid fast orange light on the charger, and yes, I tried 2 diffrent chargers, they both do the same thing.
Can someone explain a fix for this thing ?
I get no sound, no display, nothing but a blinking orange light on the charger. really fast steadily blinking.
If you can't it might be that the power management board is broken.
You might need to either take it back (if possible) or get it fixed.
Yes, I tried resetting the PMU with absolutley no response.
Upon further inspection, using one of the guides listed on your forum, i dissasembled the G4. Quite an easy task, to my surprise. I own and operate a computer store here in La, but we do not fix or sell macs. Easier than an PC notebook, thats for sure.
Anyway, back to the question.
There is a long cable that goes from the charger jack(dc input board), to the other side of the powerbook, to a connecter under the memory board cover, its a standard plug in long white connector. Looking at the bottom of the Powerbook, battery compartment at the lower half, there is a small square chip located directly next to the left side of the connecter described above. It is swollen and cracked, and looks to need to be replaced. Two solder points, easy enough, but its so swollen. I am assuming overheated, that I cannot read the #'s on the chip, I see a + on one side, but can't make anything else out on the chip. Is this on the acutal MB, or is it a seperate plug in module that can be replaced ?
Here is what has happened so far. I am very technical when it comes to onboard schematics, so I simply got out my soldering iron on my Powerbook G4. Fixed the orange light. It was a bad transistor on the powermanagment board. Now everything comes on, but stops at the loading Apple screen. with the little loading logo, and will go no further. Any ideas?
Congratulations! Sounds like you're past the worst.
Do you have the original OS discs? If you do, try booting of those (hold down 'C' at the chime / apple logo) and see if reinstalling helps.
Alternatively try resetting the PRAM and see if that'll get you further.
Ok, I will try that as soon as I get home, and let you know if it worked.
Btw, holding down the power button resets the pmu correct? How to you reset the PRAM ?
Emergency! My iBook won't turn on! (and other power issues...)
---------------------------------------------------------------------------------
If you are experiencing trouble with power issues, such as:
- Battery charging problems
- Sudden loss of power whilst running off battery
- iBook refuses to switch on
then you might need to reset the PRAM (Parameter RAM) or the PMU (Power Management Unit).
To reset the PRAM, hold Apple-Option-P-R simultaneously at the Apple logo.
To reset the PMU, hold down “Shift-Control-Option-Power “.
(Neither of these should delete any data - some settings might be lost though)
Great forum, great response.
I had to use the disk fix problem to make it boot up.Soooooooooo...
From a Completely dead D.O.A Powerbook G4, to a NOW COMPLETLEY PERFECTLY WORKING UNIT!
Hey everyone,
I registered just to ask this question everyone seems to know so much about macs unlike me
Ive got an iBook g4 and have no idea on how to make the microphone work...
I installed Audacity to try and see if i could tape something but it just comes up with like a kinda buzzing ringing noise I tried testing out the settings in system preferences-sound- sound input but anything i try never works. I have to do a presentation for school in the next couple of weeks so i really need it to work.
Any help, suggestions anything would be greatly appriciated!
Thank you
Tina
ibook glitch - missing desktop.fixed by adobe bridge!!
i was up all night last night fixing my ibook.
i made a silly mistake of when using IMOVIE, saved a movie from 'movie-tif'
so i had 3mins worth of tif frame by frame appear on the desktop.
there were over 3 thousand!
my mac froze and to cut a long story-
i had to reboot 6 times via the C button, NO JOY!!!
tried system reboot, STILL no joy.
all my icons disappeared and i couldnt access the menus from Finder.
AAAAHHH ! i was at my wits end.
what was also distressing, was my cpu fan kept cutting in every 10 mins as the overload of tif was nuking the HD.
i didnt know how to access my HD as i only had the apps bar working.
i tried EVERYTHING from going in via photoshop - to automator etc.....NOTHING
then i remembered as im on CS2, i have Adobe Bridge.
i remembered that Bridge shows files in all apps. INCL my desktop.
so anyway- I saw the list of files via Adobe Bridge.
over 3k!!!
i was able to meticulously delete each one (else it crashed)
and the cpu was really whirring by now!
i wasnt able to access the Trash to empty it, and the fan was still whirring and my desktop was still bust.
so- before i was considering spending a minimum of £80 to get someone to look at it, I backed up all my work on my 60gig external HD, and powered down by forcing it.
(hold down C) for few secs
waited a few secs and rebooted.
i almost CRIED with joy when i saw the icons appearing on the desktop.
AND, i was able to access Trash and clear it out.
i then shut down and restarted.
all is good!
phew. the all-night operation but fixed!
took me abt 2 hours!!!! i didnt know what to do at first,
i dont want to do that again.,
my tip is, if ever you have a similar thing and the desktop doesnt function and the icons dissapear and the cpu is forever whirring due to overload-
try accessing your HD via adobe bridge.
with me, my mouse worked and it was fireing up quickly, its just that the overload of tif files made the desktop crash out.
it worked for me and i am amazed at myself for fixing it.
