Can someone look at the information I've attached and extrapolate if this means my battery is "close to" DEAD?
Slowly over the last 3 months my computer shows a 100% charge and when I uplug the adapter it gets to about 90% (within 3-4 minutes) and then shuts down without a warning.
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 turned on my rev C MBA using the battery power. It booted properly but soon after I logged in, my MBA suddenly went off (as if I holded the power button for a few seconds).
Then, I've decided to power cycle it. Still the same thing: it shut downs unexpectedly. The moment it shuts down is quite random, but I cannot use the Air on battery for more than a few minutes (less than 5 minutes actually).
Hence, I decided to charge it overnight. This morning, to my surprise, the charging light on the adapter was amber (not green).
So, it seems like I cannot recharge my battery. I've reset the PMU and this doesn't help. Please note that I haven't used the MBA for a few weeks, leaving it unplugged.
I don't know whether it had some impact or not on the battery.
iBook G4 about 9 months old. I checked the battery recall and my first few numbers match, but not the second set, so I'm guessing I'm ok. The battery has been more than awesome but past couple days it has been a little weak. Today however is bad. Battery is now at 89% and says 0:27 until Full(it's charging right now). Earlier I was running just on battery and within 10 minutes it went from 99% to 86%(which is when i plugged it in). Usually it says around 5:00+ hours but it was at 3:30 hours@99%. Still with me? What I am wondering is if there is a simple solution to this and maybe the battery isn't connected in all the way or something. Or if it is failing(randomly out of nowhere) what to do and how much to replace. Or to call apple and check about the recall. I want to say it's coincidence that this is going on now after I just heard about the battery recall. Oh, and FYI maybe this helps. Last night I did leave it on the whole time with it plugged in. I was downloading a large ISO and didn't stay up for it to finish. That is the first/only time I've done that. I'm stupid. I wasn't thinking straight and the 0:27 thing is exactly what it says. 27min until the battery is full, not until the PC dies. Otherwise I need help with the other problems. I will be calibrating it today as well.
View 1 Replies View RelatedI did a thread search and could find lots of instances of an ibook not seeing or using the battery, but I seem to have the opposite problem. I have an ibook g3 700mhz (dual usb). It will only boot and run off the battery. It will not boot or run if it is only plugged in (dead battery or no battery = no running or booting). When plugged into a 45W white charger (that works on other ibooks of the same ilk), it will be green without battery and orange when the battery is in. It will not charge a battery. I've tried:
two other dc-in boards and cables known to work in other ibooks
two different batteries (that charge in another machine)
PMU reset (the light on the charger changes to green for 3 seconds, seemingly indicating the reset was done correctly)
for fun I put in a hard drive that worked in another machine and added ram that works in another machine all to no avail. What the heck is going on?
My iBook used to come up with an alert that it was using reserve power, and then automatically go to sleep, so I could wake it as soon as I plugged it in. Now, there is no warning, if it gets to 0% it turns off, NOT sleeps but turns completely off without shutting down. This means any unsaved work is lost etc, its not at all good. Can anyone tell me how to fix this? (I have Tiger, iBook 1.44Ghz, 1.25 RAM)
View 22 Replies View RelatedMy 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?
View 3 Replies View RelatedMy mum has an trusty iBook G4, and finally, after ~4 years now, the battery is on the fritz. I have tried resetting PMU, but it appears the battery itself is on the way out. Is it worth purchasing a new battery for it? Or should I tell her to take the plunge and buy a low-end Macbook [non pro] to replace it?
View 7 Replies View RelatedRecently my friend came into possession of a used iBook G3 (I don't know the specs off hand; but it runs Tiger okay), and ran into a slight problem. It appears as though the battery doesn't fully charge, and loses power 5 minutes after it being unplugged. I've looked at the battery, and it appears okay--although possibly lose. I'm sure that Apple wouldn't do repairs on it anymore, but does anyone know why the battery might not be working? If specs are needed I can provide them. But its an iBook G3 running Tiger.
View 2 Replies View RelatedI 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.
View 3 Replies View RelatedI recently bought an iBook G4 off eBay. There is one issue with it and I am not sure what is causing it. The battery shows it has about 35 charge cycles, and when it is fully charged it says around 5-6 hours of battery life left. I will use the laptop for around an hour, at which point the battery life is at around 80% with around 3-4 hours remaining. All of a sudden, the computer will go into sleep mode and when I plug the charger in, the battery is at 0% and charging! I am not sure if this is a bad battery that is old and can't hold a charge, or what. I have already tried resetting the PRAM and PMU but with no luck.

Lately when I plug in and start up I have to go through the reset time and date etc.
I have heard that some of the newer laptops don't have the back up battery. Does this one, and how do I get to it to change it?
I've had the Rev A 64SSD for about 4-6 weeks (brand new from Apple), and last night when it reached low battery with 18 minutes left I plugged in the charger.
A couple of hours later I unplugged it and it still only had 18 minutes remaining. That was bizarre because it was obviously plugged in and switched on (the screen goes brighter once the charger is plugged in).
I tried again this morning and the same thing It only stays on if it's plugged in!
Do I need to return it? Can I go into the Apple store if I bought it online? If it does have to be sent away, do they provide a replacement?
It's in a white Macbook that is 44 months old. Is there any hope for my battery?
View 10 Replies View RelatedI have a battery from an older MacBook I'm trying to use as a backup with my new MacBook. They are both white, same size, both Intel Macs.
The battery certainly fits. The problem is, it shows no bars even after charging for a while. The percentage says zero and doesn't change even after 45 minutes or so.
Is this battery ruined, or needs to charge all night? Or could it be that it doesn't work with this computer, even though they seem to be interchangeable?
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 have a g3 ibook here, and after having plugged in to charge for 4 hours, the battery meter on my menu bar still says only 12%, but three hours of life remaining. or, if it says 80%, i have 22 hours of juice. how do i fix this bullcrap?

have u guys done this? I dont want to end up with something that won't work just because I bought it at a non-Apple site...
I have a 366 G3 graphite iBook that was working fine in OS9 a few months ago. I took it out of the closet yesterday and installed 10.3. I did all the updates etc., and now the computer will not recognize the battery! There is a battery icon on top, but when the light is amber on the machine (charging) it says it is calculating how long it will take to charge. Once the light is green (charged) it says there is no battery. I take out the plug and the machine turns off. On top of that, the clock has to be reset everytime I unplug the machine. I don't get it, the battery was like new back in September - it would go for hours. Now it's like it's not even there!
View 6 Replies View RelatedI have an 14" iBook, 1.07 GHz and it won't use battery power. As soon as I unplug it it turns off. It worked fine until I opened it up and swapped in a DVD-RW and a new hard drive (the old one was failing). In the power section of system profiler it shows 98 load cycles and about a 75% remaining capacity. It may or may not be charging - I can't tell. The battery says it's fully charged at 95% and I have no way to drain it and see if it will recharge because the computer won't drink from the battery. I had another 14" iBook battery laying around that I thought worked, but now when I put it in this computer it just sits at 0% then eventually says the battery is dead (the menu icon shows an X through it).

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.
iBook G4 14" Mac OS X (10.4.10) NewerTech 74w Battery, 1.5gb ram
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.
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?
View 1 Replies View RelatedMy ibook G4 (running leopard) has a battery that seems to drop from around 75% to the computer shutting down completely (ncluding loss of prefered wifi network) in literally the blink of an eye, with no warning. I have calibrated it. I tried running coconut battery to see its vitals and the program tells me crazy things like it can charge to 12666mAh which we all know is impossible. Any ideas at all? The apple info says it has around 206 cycles on it total. Do I need to just cough up and buy a new battery? I'm hoping not as I just got the computer used through the marketplace and the guy before said he was getting 2-3 hours still.
View 4 Replies View RelatedMy iBook G4 occasionally cuts out without warning when it's being powered by the battery.The battery still seems to have charge - it will light up all 4 charge lights when the button on the battery itself is pressed.It also boots back up straight away when the power on button is pressed after having cut out.This has never happened when the iBook is plugged in to the mains supply.

Second,my battery did some strange thing,it shuts off @30% sometimes 40%,but it shows 92% health and lasts 2/4hours,in an attempt to do something I tried a routine of discharging and full charging it,and it had been earning mah lol..is this possible?why does it happen?can it be because it was not very used by the last owner? here it is a screenie: istat says the same.. Do I have a very good battery,or one that in a few days is going to heaven?
View 2 Replies View Relatedwhile using my 14" G4 iBook, I notice the battery was getting a little low, so I plugged in the charger. When I did, the charger plug did not glow at all, and while the battery icon on the menu bar changed from "battery" to "plugged in", it indicated the battery was not charging. This morning I did an experiment with a second iBook and charger. The problem is definitely not with the charger, since it works fine and "glows" when plugged into the other iBook. Likewise, no matter what charger I plug into my iBook, I cannot get the battery to charge nor will the charger plug glow. My iBook will run without a battery plugged in, so at least I can still use it when the battery eventually runs out of it's current charge. Does this sound like a DC-in board issue? I've found one on-line to purchase and it doesn't look to hard to install (I've done HD swaps in my iBook before). I'd really like to keep this laptop running for a little while longer.
