PowerPC :: IBook Battery Charge Low - Shuts Down Without Warning
Oct 7, 2007
My school-computer (iBook 14" 1,42 Ghz G4, running OSX 10.4.10) has developed some unpleasant habbits lately. With lots of batterycharge left, 28-50%, it shuts down without warning. I try to restart it, and it gets to various stages of booting before shutting down again. It won't run untill i plug in the powercable, and then it starts of from almost half full charge. I did a bit of searching on the forums, and installed coconutbattery with the attached (depressing) result. Tried resetting the pmu, which didn't stop it from shutting down on me again 46 mins later. Does this mean I need to replace the battery?
my daughter bought a used ibook g4 15" and it worked for several months before developing a maddening habit of shutting down without warning. I've read other threads about this with ibooks but they say it happens only when the battery is operating and doesn't happen when plugged in. My daughter's does it either way and will only stay on for ten or so minutes most times before shutting down. It makes the machine unusable. We've checked the power supply and the power input board. Is this a logic board issue? She paid $450 for the computer but the prices have come down and it might not be worth fixing. I can solder and can get into the logic board if someone can tell me what to do.
I was hoping you could get me started in the right direction. My wife has an iBook G4 which lately, while using a full battery, just turns off suddenly. There is no warning and it never does it when it's plugged in. The battery looks like it's almost fully charged - at least that's what the meter in the menu says, so I don't know what's going on.
Could you possibly give me some steps to go through to try and figure this out?
The first step she wants to try is to get a new Intel MacBook, but I'd like to try a couple of other things first!
My iBook G4 is 3 years old. I have 2 problems: My latest problem is that it won't charge the battery. I bought a new Ac Adaptor, and I used my battery and my adaptor in another G4 and it charges, but not in my computer. So I know the problem is INSIDE my computer. My father replaced the.DC-inboard when the pin off of my old charger broke off inside the computer.
2.) Now the computer won't turn on. If it does turn on it shuts off 20 seconds later.
There is no warranty, I don't know where to start with fixing it since I can't get it to stay on.!
My iBook G3 800 MHz will not charge any more all of a sudden. I have tried plugging it in to several power sockets and it won't charge. Whats more... I tried charging it with just the normal charger, and I even tried charing it with the extension wire! I am not sure if it is the charger, or my iBook. If it is the iBook, should i rip it open and get a new part for it? If it is the charger, where can i get a new one?
I just tried to charge my iBook, and it won't charge. If I unplug the charger from the mains socket, and plug it back in, the ring around the charger will turn green for about a second and then turn off. I've tried to restart the iBook, and I've removed the battery from it also.
I have done all those PMU resetting stuff. The problem is that my iBook (1GHz, 768MB RAM, Tiger 10.4.3) keeps shutting off when I run it on battery. While plugged in there doesn't seem to be a problem. Here's what I've found out: This seems to happen only when I run the iBook from the battery. There is no pattern as to when it will happen: It might be fully charged, at 70%, 50%, etc. There are no warnings: The iBook just dies
To restart it I have to plug in the charger, I can't start it from the battery after one of these sudden deaths
If I press the battery indicator after a crash, it doesn't show any charge - no green lights When I restart the machine the battery indicator will work, and it show's a charge in Tiger as well
I've done all that PMU resetting, PRAM resetting, etc. Doesn't work. Any ideas as to what this could be? Bad battery?
One more thing: I've run the hardware test, and it doesn't come up with anything at all.
Coconut Battery shows that my battery should hold a charge as well. Max charge is still at 3500mAh, 18 months and 750 cycles after I got the iBook.
I recently purchased an iBook used from someone locally. I got a good price because he said the battery was weak. However, I want to make sure that's actually the case. The power cord connection is not loose.
Coconutbattery says my battery is 36% health, but it also says it's not plugged into the charger when it actually is, so I don't know how reliable this program is. It says my mac is 27 months old, i have 367 cycles on the battery... etc. And I am running Tiger.
The problem is that the power meter on the top bar will say i've got a full charge... so I run the computer (on battery) down to about 60% according to the meter, but the computer instantly shuts off. I try to reboot, and it shuts off while rebooting. It's like the battery works fine and suddenly dies. I get about 30-40 minutes use out of the battery.
Is this the battery or do I have other problems? This only happens when using the battery.
I just bought a 74w NewerTech battery about 3 weeks ago but I don't think that is the problem....
I can run my iBook off of the AC adapter fine but when I unplug it it automatically shuts off as if there is no battery in it.
It shows that the battery is charging and everything in the menubar but when I unplug it, it will shut off. This just happened today and earlier today I was working on it with the battery working fine.
I also switched out to the old stock battery and it does the same thing.
I think it has to be hardware related. I have reset the PMU and PRAM/NVRAM and it didn't help. Also when I started the computer back up it said that my clock was reset. Feedback is much appreciated.

My adapter caught on fire, and I had to put it out. When I tried to charge my battery with a new adapter, it would not charge. I got another battery, (old one from a friend), that apparently had some juice left on it. The computer turned on no problem, and I used it for about 20 minutes when I noticed that the battery was slowly dying, and that it would not charge again. Now, its dead again. It will not charge. Does this sound like a logic board problem? Who can I contact?
I've had my iBook G4 for about 4 years now. I replaced the battery two years ago and have had to replace the charger twice. My current charger, which I bought rather cheaply on ebay, will only charge the battery when my computer is shut down or sleeping.
This makes it very difficult to work as my current battery is losing charge quickly and plugging it in is of no use when I am using it.
Is there anything I can do to change this? Or do I need a new battery?
i made my own power supply wall plugin cable for my ibook g3 power adapter. Its from a printer, computer boots fine, but with only one problem it wont charge the battery is this because i only have the two prongs connected to power while the weird silver circle doesnt have any power"
Sometimes my MacBook will shut off for no reason, and then it won't charge anymore. It takes a lot of effort to get it to start charging again, but I don't get it. I don't know what's wrong with it. It just started happening randomly, I don't know what to do. It's under warranty, but I wanted to see if anyone else was having this problem as well? If there's any quick fixes please let me know
I am looking for an external battery dock to charge the battery. The Mac people said it's an internal problem in the computer and it will be $300 to fix. Are there any external chargers for Ibooks out there?
Last month my old charger died (literally, it blew up.), so I got a generic one. It worked for a while then it wouldn't charge. Basically it would charge for a second then stop, after about 5 minutes of crapping about with it it would stay charging. Then like a week later it stopped doing this and with the generic charger it'd charge when plugged in right away, no fights. Now today it decides to do it again, BUT it won't charge no matter how long I jiggle the wire around etc.
Would this be the DC board? I don't want to buy another charger finding out it's the DC board, or vice versa.. If it is the DC board, does anyone have a link to a site to show how to install a new one? If it's a big hassle, I might see if theres an apple shop around town. Also: It does this with the battery out as well, so it's not the battery.
I have this iBook G4 and the wierdest thing is happening. When it is on and you bump it or move it a little it just shuts off like a hard shut down. Has anyone else out there heard of this problem or does anyone know how to fix it?
I have an ibook G4 14" 1.42ghz.I have it plugged into a power adapter almost always. It has been plugged in in both instances/I recently put it to sleep and when I return anywhere from 15 minutes to a couple hours it is shut down. I have a heck of a time getting it to power on. It took me several times, anywhere from 3-6 times to get it to turn on.
When I turn it on it goes through the usual loading procedures and after loading a window pops up saying the date and time are wrong and could cause applications to act erratically. The date ends up being 1969 and sometimes the time is wrong.
I have fixed the date and it still happens.
I don't know if this has affected or led to this but my battery has been shot for a couple months now and occasionally (probably 1-2 times a day) the power adapter (a cheap copy of apple's) would become unplugged from the laptop prompting the message stating you are on reserve battery and that the computer will go to sleep soon.
Does anyone know what is causing this? How much would it cost to fix it?
It ran fine off of a battery, but won't charge. I replaced the DC board and the power adapter, but it still won't run or charge off the battery. I think the original power adapter was bad and ruined the original DC board and the new one. I'm going to try one more DC board and if it doesn't work then give up the parts on eBay. Problem is, I need the data off the hard drive. Is there anyone in the Kansas City area who has an iBook 14" 1.42 GHz and would would be willing to charge the batteries for me? I wonder if the Apple Store might do this? This way, I can turn on the iBook and copy the data to another machine.
I have an iBook g3 running Tiger that I bought second hand almost two years ago that has been working perfectly up until yesterday. I use it for uni during the day and usually turn the machine off overnight while it charges. The other night I left it 'asleep' while charging instead of off. When I came to use it in the morning it would not wake up and was totally silent although it's pulsing 'on' light in the front part of the casing was on. The charging cable was still connected and was green, indicating a full charge, but the battery-life light display, when pressed, showed only a single light, which flashds a few times, indicating the battery wasn't fully charged.
While trying to get the thing to do something I removed the battery. This caused the ibook to turn off the pulsating light - it was completely off and apparently not drawing power from it's adapter, which was still plugged in. I have been trying since then to get the computer to turn on. No matter how long it is left charging, the battery never indicates anything other than a single light with a few flashes, the computer will not turn on and the cable of the charger stays green when plugged in. I have tried inserting an older battery - which I know worked, it just only used to hold an hour's charge or so - and it will not charge at all. I have also tried resetting the PMU, which appears to have done nothing
My wife has a three-year old iBook G4 and yesterday while she was doing some work, the screen just went black. By the time she brought it to me the machine was shut down. I hit the power button and it started to boot up, but about five seconds later it shut itself down again.
I kept playing with it and I was able to get back in to OS X and I played with it for a few minutes and all seemed fine. I then shut the screen and put it to sleep, then when I tried to wake it back up it shut itself down once again.
After a few more tries of getting it back in to the OS I was able to get all her files off the hard drive, but the problem is still there.
My guess is that it's the logic board, but that's just a guess.
I was given an old ibook G4, with a borken hard drive.
since it would boot from a firewire drive on mac os X 10.4 ppc, I decided to change the hard drive, which i had never doe for a laptop. I had a very similar 40 Gig toshiba IDE drive from an old laptop, opened the ibook and changed the drive.
everything works, the mac boots fine, sound, video etc, yet I realised that it had one rather serious issue. It shuts down when moved / tapped, even very lightly, and this is problematic for a laptop. I was considering buying an airport extreme for it, but now I'm afraid this might not be mendable, nd i'm reconsidering.
what could be wrong ? is there somekind of shock sensor that could have been damaged ? I put back all the screws, and only changed the drive and proceeded cautiously, but maybe something was damaged- what could be causing this, is there a specific area I should focus on ?
I have a 1.2 Ghz Power PC Ibook that has been a flawless laptop for almost two years now. Yesterday, I noticed that the screen wold periodically dim/brighten every couple of seconds. As I looked at the battery icon, I noticed that each time it dimmed, the charge icon would switch to a battery (as if the laptop wasn't plugged in), and each time it brightened, the corresponding charge icon would appear.
This happens even though it is plugged in, and usually, if I adjust the power cord, then it stops. But each time I have had to do this, it becomes less responsive to the method! Now I'm afraid my computer will simply die a slow death, with me frantically jiggling a cord to no avail, watching as it breathes its last breath, unable to be repowered!
PS: I'm an American, in Germany, who will be in London next week and able to visit a genius bar there...but I'm not positive that my warrranty extends beyond American borders.
I have a question on the charge indicator on my wife's G4. Her DC in-board was acting flaky where it would alternate between charging and not charging every 5 minutes. I searched the internet and determined it was the DC in-board and I bought the part and swapped it out myself. I just replaced that in her laptop and it now doesn't do that but I do have another question on the expected G4 behavior. When the battery is running low with the lid open and I plug in the power cord it will turn orange to indicate it is charging If I close the lid it stays orange and goes to sleep as expected. But if I then open the lid it will turn green for a couple minutes and then go to orange.
Shouldn't it stay orange the whole time no matter if I take it out of sleep mode or not? My Macbook Pro stays orange once it is charging and doesn't stop until it is fully charged. The reason it concerns me is I just replaced the battery on her laptop after the DC in-board issues described above. The constant charge/no charge made her battery only hold a 20 minute charge. It seems switching from charge to no-charge for the couple minutes after waking up would mess with the battery as well. I reset her Power Management Unit thinking that would clear things up maybe and had no effect. Can someone confirm if her computer if behaving as it should.
I was wondering if anyone would be able to help me or if anyone is having the same problem as me... Since 16th Feb I have not been able to charge my ibook in sleep mode. Every time you put the ibook into sleep mode while the power cable is connected the ibook goes to sleep for a second or so and then wakes up again... If the screen is shut it just continuously keeps repeating the process...
I would be very grateful if anyone could advice me on what to do or recommend any diagnostic checks i should do to rectify the problem...
