I usually use my laptop at a desk plugged into an AC outlet. Well I was going to be away for a week, so I unplugged it, when I came back, the battery went from 97%, not charging to 12% when I booted the laptop up again.
Also, can one continue using a macbook laptop if the battery is dead, but run it through or plugged into an ac outlet all the time?
I made the mistake of unplugging and removing the battery from my iBook while in sleep mode, to reinsert a screw I found on the floor. Now at startup it's stuck on the blue screen. I've tried several resets, icluding shift-command-option-power, zapping the PRAM command-option-P-R which got my "startup sound" back, which I let chime 3X, I reset the NVRAM, single user mode confirmed the clock was reset (to 1904) and an fsck said the system "Appears to be OK." I've had no luck with "safe boot," I have no reset button and no OS disk to boot from. Verbose mode prints up the same 10 lines over and over "(error) imprt: importer start failed for 89, invalid destination port, no such file directory, run loop could not be started." It's a 14" iBook G4 running OS 10.5.6. I don't mind if files are lost-there's nothing important on there.
View 1 Replies View RelatedI was sick of the battery life I was getting on my 15" Macbook Pro 3,1 (early 2008 model), so I went to the apple store yesterday to get a new one. I was over 400 cycles, so I had to just buy it, they wouldn't replace it for me. I expected that, so no big deal. But I wanted to treat this battery right. I got home, charged it up to 100%, let it sit at that for a few hours, and then let it drain overnight and rest at empty for a few hours. This afternoon, I plugged it back in with the intention of letting it fully charge and thus complete my battery calibration, but at around 40% charged, the cat yanked the charger cable out from my laptop. And then a little bit later, my girlfriend did it again. So, has my time been wasted here? Battery calibration is such a pain in my rear. i hate it. I use my laptop often and expect it to be available to me whenever I need it, regardless of how many other computers i own. I really don't want to deal with it again in the near future. And I may not.
View 3 Replies View RelatedI have a 3 1/2 year old Macbook, my Applecare has ran out. About six months ago my computer began shutting off immediately when unplugged. (Was letting my roomates use the computer, came home one day and it started doing this.) I believe that my battery is OK, it performs between 97% and 99% consistently. When I do the battery test, all of the lights light up.
I've read through the forums and it seems a lot of people are having this problem, but their batteries are bad. What are some options/solutions to this problem? I am willing to invest money wisely into the computer to keep it running smoothly for a while.
I've tried two brand new adapters and neither work after my MBP is unplugged for a few hours and then plugged back in. Eventually it'll work again, but occasionally it doesn't acknowledge the power source. Will AppleCare cover this?
View 1 Replies View RelatedI have an early 2011 MacBook Pro 15 in. that i got in May of 2011. When i unplug the power adapter it works fine, but at about 80% battery it shuts off. i go to turn it back on and it acts as if it is dead, i press the power button again and it turns on without problem (although the date and time at first is messed up). What is wrong? I recently had to get my hard drive replaced 2 months ago and it has been working fine until yesterday.

So I usually keep my UMBP plugged in at all times. It unplugged by accident and went to 99% so I left it unplugged but literally less then maybe 7 minutes my battery is already reading down to 92%. Brightness on screen is set all the way up, if that has anything to do with it.
View 1 Replies View RelatedFirstly i have a MacBook 10.4.11 that is somewhere between 2 and 3 years old. I have had no problems with the Mac up until yesterday. Yesterday i was charging my Mac and everything was fine but i noticed that the MagSafe Adapter was lit up Green, even when unplugged from my Mac. I shrugged it off until this morning when i realised that when i unplug my adapter the Mac just turns off and won't turn back on until i plug the adapter back in. I have seen different threads about it being a battery problem or a charger problem but i am not sure where to start as most of the threads say that their Battery Icon on the Mac screen has a black "X" through it. Mine just has the Forks in the battery icon and where it would have a Time or % of what is left in the Battery, it just has a (Calculating...) and when i click to see how much it has charged, it says 0%
I also downloaded Coconut Battery and here is what it says:

My 10 month old Macbook Air 13" battery behaves weird every 4 weeks. When unplugged the MBA switches off suddenly without a warning even the battery is still more than half full. Plugging it in it tells it takes 20 hours for a full charge but never gets full. After unplugging it crashes after some minutes again and goes dark.
The battery' got 178 load cycles and 5675 mAh out of originally 6700 mAh (84%). Did several SMC resets and PRAM resets. I even reinstalled Lion from scratch without changing the battery's behavior. Calibrating the battery isn't possible because it does not discharge but crashes. I tried three different power adapters.

MBP plugged in, lid closed, using external monitor only. But when I unplug it, it immediately goes into sleep mode and doesn't wake until I open the lid.
View 8 Replies View RelatedMy Macbook shuts off immediately when unplugged and will not start up unless it's plugged in. This just started last night...I was using it while it was charging and then unplugged it when it got to 100%, and it immediately shut off. Prior to this, it seemed to be charging and running fine. It also runs fine plugged in.
I did some searching and tried some of the suggestions I found...shutting down, taking the battery out, holding down the power button for 5 secs, and replacing the battery...making sure the connectors were clean, downloading battery update, etc. Nothing helped. I also read an article about how the lithium polymer batteries will just quit suddenly like that instead of running down gradually. So I'm hoping all I need is to buy a new battery. But my question is this: Since the system profiler shows the battery health is "good," does this indicate something else is the problem? Or will it still show it's good after it completely dies?
Here are the stats according to System Profiler:
Charge Information:
Charge remaining (mAh):3955
Fully charged:Yes
Charging:No
Full charge capacity (mAh):3956

I am just now learning about these things, so apparently 1047 cycles is a good life for the battery. I just want to know that this is the only problem so I can order a battery and be done with it. Wish I could run it over to the Apple store and have them check it, but it's an hour and a half away, so if I do that, it'll have to be later in the week or next week. Naturally, I don't want to be patient and wait.
When I unplug my charger from the side of my computer, my brightness on my MacBook goes down a few notches. Why does this happen and how can I fix it?

View 10 Replies View RelatedI have a macbook mid 2007 that shuts down immediately after it is unplugged from AC. I've tried the battery on another machine and it works fine as well as trying a known good battery in this machine.Also I've tried a known good AC adapter. Other things I have done are run the hardware test which shows no errors, reset the smc and Pram, repaired permissions etc. the battery appears normal in the menu bar and says it is fully charged.Also it Appears in system information as normal.coconut battery also appears normal with 275 cycles.I'm hoping the problem lies in the Battery Connector with Sleep Switch and not the logic board. Anyone had any experience with this problem?
One other strange thing is that after unplugging the AC the system shuts down immediately, but once you plug it back in it starts without the power button being pressed.
My iPod Touch only turns on when its docked on my radio/ipod dock but will immediately turn off as soon as I take it from it. It won't even turn on and sync when connected to my macbook. The iPod has never had battery problems or anything else wrong with it.
View 2 Replies View RelatedI used Bootcamp to install Vista on my Mac Book Pro 2.4 Ghz (April '08). It has been working very well until Dec 2008. While running a PC game on battery, Vista operating system would just shut down unexpectedly. If the machine is plugged in, it would work fine. Currently the problem is getting worse; when I boot up into Vista on battery, it would shut down in about 2-3 minutes.
Initially I thought it was a battery problem. I booted up into Leopard and checked the battery information in System Profiler. I didn't see any problem. 332 cycles and condition is "Good." In addition, Leopard works just fine on battery.
several months ago when my ibook g4 was just over a year old it began suddenly going to a blank screen when the battery was fully charged and the computer was unplugged. Sometimes i would hold down the power button and the computer would come back from seemingly having fallen asleep. other times i would have to plug the computer in and hold down the power button for it to come back. to do this it would make this whirring fan sound before going from a black to a gray screen and then finally re-starting up from the beginning. a box would then appear telling me that my date and time were set wrong and that this could cause some functions to behave erratically. this despite my having frequently changed the date and time zone back to my own and locking the settings. the computer keeps switching the date back to 1969. and now when i put a dvd into the computer it just spits it back out and won't play it. long story short...i am beginning to hate my mac. what's the point of a laptop if you have to leave it plugged in for it to work. apple tech support has done nothing to help me and has refused to admit that the g4's have a problem despite my having read about tons of people having these exact same problems after a year. i read something about how in denmark this consumer group proved that there was a faulty part attached to the battery coming loose and that they were suing apple.

Well, I just got a replacement door because the door wasn't sealed properly after use. The hooks are more curved and the front of the device looks proper. However, there is still one corner sticking up which also makes a metallic noise when I set it down. So I tried putting some wall stickers on there, but they were too think so I found some double stick tape and stuck it on the rim surrounding the battery and then the battery itself. I might request another door from Apple, but for the moment is this a OK thing to do? I had thought about the detrimental effects of this thin plastic on the battery, but the tongue (to take out the battery) looks as if it's plastic as well.
Is putting tape on my battery to fix the door issues a bad idea?

When you unplug power from your MBP, the battery icon is supposed to show the battery level. Right now, mine shows the plug icon and if I click it it says power source is the power adapter. It's sitting in my lap not plugged in.

I'm not sure if this is should be in hardware or software, so I apologize if this is in the wrong catagory.
I have a "5,1" Late 2008 Aluminum MacBook
2.0 Ghz

I just replaced the stock 160gb hard drive with a 500 gb Seagate. Everything is working perfectly except for one odd issue:
While plugged in, the MacBook says it is charging normally and appears to actually be doing so. However, when I unplug it, it shows the plug icon on the battery as it does at 100% charge and says "(Not Charging)". Power management wise it also behaves as if it is plugged in. So, as you can imagine that is quite annoying as it doesn't dim / sleep when it should if left sitting and I can't see my battery % when it is unplugged. I have looked EVERYWHERE on the net to no avail. The MacBook is no longer under warranty so no dice there. I have also checked my energy settings as well as reset the SMC.
