I have a 1.33Ghz 12" powerbook and recently it has started to just shut off when the battery is saying it has around a half hour left, instead of it warning me that the battery is low and it will go to sleep soon. and then it won't restart until I plug it in. is there any way for me to fix this besides getting a new battery? This battery is not covered under any recalls, and there is no applecare left on the computer. also if it matters the computer is running 10.4.10.
I have a 1.67 GHz Powerbook G4. This morning it was fine. When I got home from work, it decided that it suddenly no longer wants to stay on when not plugged in. The battery is showing a full charge. The light on the plug is green. But the second I unplug the cord from the laptop, the entire thing shuts down.
I bought a 3rd party battery for my MBP. I put it in and after cycling the battery i noticed that the full charge capacity was only 3990mAh (supposed to be 5500mAh). I returned the battery today and got and an upgraded replacement. this shows the full charge capacity at 4995mAh (supposed to be 5600mAh).
is this normal. Do I just need to give it some time or is it something with the batteries.
Why is my Mac not at 100% battery after having it powered off and plugged in charging all night? As long as my charger is plugged in shouldn't it be at 100%? I never unplug it. It shows it is charging but stays at a constant 98%.
Info: MacBook Pro (13-inch Late 2011), Mac OS X (10.7.3)
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.
Some days ago i finally added a Powerbook g4 to my Mac collection and since then ive been trying to fix this computer without any results. The Powerbook had the battery dead at first and i had to replace it with a new one i had. Now the problem/weird thing is that the computer detects the battery but it doesnt charge. It has about 18% of the charge and when i try to boot up all i hear is like a fan sound and nothing more, no boot up sound and no image on the screen.
If i boot up using the power cable thats when i see the 18% of the battery icon, but as soon as i take out the power cord, the image goes black although the computer still makes sounds as if it was on. Does it have any solution? PS: ive tried to reset the PMU,changed the pRam for a new one, reset the Nvram.
for some reason my powerbook battery charge slowly goes down even while it's plugged in. The power light is green as if it's fully charged but it goes down about 1% every day and then if i unplug it and plug it back in then it starts to charge, goes up to 100% like it should and then starts all over again. It never used to do this so i don't know why it's doing it now.
It started happening around the time apple had that huge recall so then i got it replaced but it still does it so it can't be the batteries fault (at least it doesn't seem likely)
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?
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?
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"
I was just looking at the battery info for my PB which is about 1.5 years old. It says that my cycle count is 59. I was wondering how many cycles the average battery will do with a reasonable charge time? My absolute max capacity is 4400. I found the information with the following command: ioreg -l -w 0 | grep IOBatteryInfo
Basically I'm having issues with my newly acquired Powerbook G4. When i bought it the battery was not working at all so have now installed a new replacememnnt battery which works fine but having some slight issues. So...
First time I charged it, it reached 100% but green light never came on to indicate full charge. When I run the PB off the battery it gets to 20% and it shuts down without any warning it's low on battery (trying to switch it on after this is impossible, it clearly has no life) After the above I connect the power lead and start up the computer, the battery indicator starts charging from 20% onwards. Something fishy definitely going on and I have no idea what it could be, I calibrated the battery but it has always cut off at 20% since first charge/discharge.
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.
I have had my macbook for just 6 months....at the beginning it was perfect with a very good battery life.Now at 99% charge (as it refuses to finish charge to 100%) It now says 10:00 where the battery time is and last less than 30mins.
Also its charge capacity is JUST 708 !!!!It was over 4000 just 6 months ago.Im sure my battery is on its last legs, anybody know if I am entitled to a free one?

purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?
been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.
I just want to make sure nothing else is wrong with my Macbook..have never replaced the battery in 3+ years...Always says not charging and once the magsafe is removed Pro shuts off...is completely dead battery the only problem..?

So, I randomly clicked on my battery and noticed this "Service Battery" message. I had never seen it before. Obviously, this isn't a good thing. My Mac is 3 and a half years old so I'm not surprised this message poped up. So, I opened Coconut Battery and noticed my current battery capacity is at 65%. Even though charger says it's green, my battery isn't even charging. Should I make an appointment with Apple? My AppleCare expired so i'll have to buy a new battery when the time comes. I'm sure they're not cheap, either.
For some reason, when I was in either my D-Link or now my new Airport Extreme's logs and looking at the current connected wireless clients, my new Macbook Pro's name is always missing. Everyone elses laptops, desktops, and my iPod Touch all have names.
I looked under "System Preferences", then "Sharing", I do have a name there.
Running 10.5.6 with an SCR331, G4 desktop. I have been using entourage, smart card reader, and CAC successfully for quite some time.
My CAC was recently updated with new certificates to transfer my email to navy.mil. When I insert my card reader with CAC into my machine, the keychain (and Entourage) show the old certificates (with the spawar.navy.mil account) which aren't even on my CAC anymore. Obviously I can't get Entourage (or other websites) to work without being able to access the new certs.
I use a Mac Mini to launch iTunes with library saved in an external drive. Now my Mac Mini retires and I replaced it with a new one. I launch iTunes on the new Mac and reconnect to the library in the external drive.
How come my wav files are shown in correct albums in old Mac but shown in unknown albums in new Mac? What must I transfer from the old mac to new mac show wav files in their right places?
I have tried importing the library xml file but it didn't work.
I have a Mac 10.6.8 running Snow Leopard. My battery won't charge: all I get is "Not Charging" in the menu bar battery status; the power adapter doesn't light up either. It's not a problem with the battery—when I put my battery in my friend's MacBook, it worked just fine. His battery, however, wouldn't charge either when it was in my computer. I have tried resetting the SMC several times, following the instructions exactly. I've reset the PRAM, run disk repair, and fixed disk permissions. I don't have the money to take it to a repairman—even if I did, I need my computer every day for work.
I'm having in issue with my 13 " macbook (Late 2008). It's not charging! When I plug my adapter in, the little charging indicator is a faint green, not the bright green it usually is. It does show on my computer that the adapter is connected, but it's not charging.I recently reformatted my whole computer (started from scratch). Also, I was having battery issues a few months back and got the battery replaced, so I don't think it's a battery issue.I also reset the PRAM and checked my adapter and port for dirt and such, but it's pretty clean.
