OS X V10.7 Lion :: Macbook Pro Shutting Off When Unplugged And At 80% Battery?

Mar 22, 2012

I 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.

MacBook Pro :: Won't Work With Battery / After Being Unplugged From AC

Dec 20, 2010

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?

MacBook Pro :: Battery Calibration / Unplugged While Recharging

Jul 19, 2009

I 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.

MacBook :: Shuts Down When Unplugged - Battery Is Good

Jan 10, 2010

I 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.

MacBook Pro :: Battery Sometimes Won't Charge After Being Unplugged For A Few Hours?

Mar 19, 2012

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?

MacBook Pro :: Battery Loosing Charge Quickly After Unplugged

Feb 16, 2010

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.

MacBook :: Battery - MagSafe Adapter Was Lit Up Green Even When Unplugged From Mac

Mar 2, 2010

Firstly 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:

Current Battery Charge: 0 mAh
Maximum Battery Charge : 5093 mAh

0%

Current Battery Capacity: 5093 mAh
Original Battery Capacity: 5020 mAg

100%

MacBook Air :: Battery Half Full But It Switches Off When Unplugged

May 1, 2012

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.

PowerPC :: Powerbook G4 Turns Off / Battery Charger Is Unplugged

Jun 20, 2005

My Powerbook G4 only turns on if the battery charger is plugged in, and if I unplug it, the computer shuts off. On the menu bar, it says charging. I know the battery has to be full. This just started happening last night. Also, I just had the hard drive replaced and I've only had it back for a couple weeks.

Software :: Won't Work With Unplugged And Removed Battery / Error

Jan 18, 2010

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.

MacBook Pro :: Computer Shutting Down After Battery Replacement?

Mar 13, 2012

I just replaced my battery and now my computer shuts down randomly no matter how much battery power I have.  Most recently it shut down with over 70% battery life. I followed the instructions on the new battery, but I can't figure out what is causing this type of issue based on my settings that didn't change from the original battery.

MacBook Pro :: 2007 Restarts Instead Of Shutting Down - Replaced Battery

Jul 31, 2010

I have a Macbook Pro from 2007 (aluminium keyboard). Everything was working great until a couple of days ago, when I replaced the battery.
No every time I choose to shut down the computer, it will restart and NOT shutdown. I have tried several things - the only thing that seems to work is to unplug the power chord - then it will shut down, but if the power plug is connected, the computer basically can't shut down - it just restarts.

MacBook :: Shutting Down Randomly - How To Prevent From Shutting Down

Mar 23, 2010

I have a MacBook which has recently been shutting down when it feels like :/ this all started a week or two ago (well not the shut downs but other issues that I'll get too), basically the fan I think has been knocked as it is bumping the top or something as the whirring is getting loud and it sounds like every now and again it hits something

Also CPU usage seems to be averaging out at 20% for Safari and 100% for HD Video where as it used to be very small amount for Safari and 30 - 40% for HD.

OS X V10.7 Lion :: Screen Randomly Shutting Off?

Jun 17, 2012

So frustrated with this situation. It appears this is only happening since upgrading to Lion so that's why I've chose to post it in this forum. My screen has been shutting off randomly. And I've only been able to get it to happen when I use gestures on the trackpad. (I.E.: "App Expose, "Show desktop" or "Show all windows.) I say my screen because the HD is still spinning, the keyboard backlights are still on and the status light is still lit. I can't do anything but hard shutdown. I've tried adjusting the brightness, clicking, keyboard commands (force quit) and nothing does anything. I've been sending the crash report to Apple but I feel like that is pointless so I'm turning to the forum for a possible answer. I've inluded my specs below as well as a copy of the log that got sent to apple (in blue). I don't know if it will say anything to anyone but it's worth a shot. I don't think it's a screen cable issue cause I'm not moving or adjusting the screen when this is happening.

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.

MacBook :: Won't Work With Unplugged / Shuts Off

Feb 16, 2010

My 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
Health Information:

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.

Every time that I unplug my MacBook it immediately shuts off. I have read similar stories but there is no black or red "x" on my battery icon. I have tried to take the battery out and put it back in but it didn't work. The light on the plug in is green and I'm not sure what is wrong.

MacBook :: Showing Its Plugged In And (Not Charging) / While Unplugged

Oct 11, 2010

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
2 gb RAm

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.
