Mac Book Pro shuts off when using the battery after about 20 minutes. System Profile information says it is fully charged. Health Information, cycle count:108, Condition: check battery. I believe I have two weeks left on the Applecare Protection Plan.
View 1 RepliesI 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 battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
I have a big problem. For some months now I haven't been able to start up my Mac. It's a Mac PowerBook G4 bought back in 2002. It's a laptop. When I push the start button it shows me the grey screen with an apple. Then the screen turns blue showing the white and square icon with an apple, Mac OSX and the line for loading saying "starting Mac OS X..." When the loading sign is complete or almost complete it stops. Nothing more happens. It just stands there the blue screen with the loading line that looks pretty complete. What can be wrong? Some time ago I was asked the message: if I want to use the new way of starting up my computer, and I clicked YES, because I thought it was the normal software updating. And eversine then it hasn't been able to finish starting up. Can anyone give me suggestions of what to do? Or maybe tell me what is wrong? Maybe it has something to do with the "new starting up" message I said yes to, or maybe not.
I really hope someone out there can give me some advice, because now I haven't been able to use my Mac for months!
I'm running Windows XP through Virtual Box on my 2.4ghz Mac Book Pro (10.5.8) - works great for my Web Designer Day Job (checking Browser issues).... anyway I borrowed a copy of Aliens Vs Predator 2 from a friend (it's an older 2001 Game) so I figured it'd run ok on a 2009 Mac even through emulation....
Anyway I'm having major Issue trying to get the game to work, Basically I think I'm missing Nvidia Drivers?
System Profiler says I have 2 Graphics cards:
NVIDIA GeForce 9400M
NVIDIA GeForce 9600M GT
I've tried downloading Nividia Drivers from there site, Both that I've tried give an error message telling me "No Suitable Hardware Found" ??
has anyone tried to play a game through Virtual Box/ XP on a Mac Book Pro?
I have Western Digital My Book Pro II 2TB hard drive connected through FireWire 800 or 400 cable. The problem is that it shuts itself off unexpectedly all the time. Sometimes right after I turn it on, sometimes after 30 minutes. After turning it back everything seems to be fine, no loss of data. Anyone else experienced the same problem and can suggest how to fix it?

I recently spilled coffee on my mid 2010 2.4ghz macbook pro. After drying out, the computer worked fine, although the battery was not recognized. Since apple does not cover water damage i bought a replacement battery and installed it today. After starting up the problem is not solved. there is still an X through the battery indicator and if i unplug the laptop it shuts down instantly. When i turn it on, the status LED on the front blinks 6 times before the laptop actually boots up. I have reset the SMC, NVRAM and PRAM.
Any help or input would be greatly appreciated.
I've got a late '06 Macbook Pro, running OS 10.4.11, 2GB RAM, 2.16GHz processor. The battery recently died, but that's not a problem as I run it via the power adapter when at home.
Problem is, since the battery packed up, the computer itself is running slower than when the battery was installed. Is this usual?
It's a dualcore processor, and was previously fast enough to watch HD movies, but now HD movies are jerky, and the whole overall operating system seems noticeably more sluggish.
I have a white macbook core2 duo. The main battery is dead and I have been using it with the power brick.
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?
Is it strange that my MacBook now just shuts down when it runs out of battery instead of just going into sleep mode? It's about two weeks old now. It used to go into sleep mode, but now it just shuts down once the battery is down. Also, I had the most wonderful experience with Apple. My first macbook (three weeks ago) had a small chip on the screen. When I finally noticed it, I thought it was a large piece of dust so it wasn't too terrible. I tried to exchange it at the local store where I purchased it, but it had already been four days and I had cut out the UPC for the printer and ipod rebate the day before and sent it out. So they recommended that I go see a mac genius and see if I can get the screen replaced because I could no longer exchange it or return it (risk losing my rebates).
So, a bit upset that I was too prompt about getting the rebates in, I scheduled an appointment with a genius. When I spoke to him, he just went to the back and got the manager. The manager said instead fixing the screen, he'd liked to give me a new macbook and instant reimbursement for the ipod and printer! (the rebates I sent in will be rejected since the mac has been returned). The new macbook I noticed has a much louder superdrive seems to be working hard every time the computer wakes up and when I open it, but that definitely beats a chip on the screen. But now it doesn't go to sleep after the battery gets low, but instead shuts off.
My MacBook shuts down on random percentages when used on battery power. I can only use it for FIVE minutes before it shuts down. And as I said, it shuts down before the battery runs down to 0%.

I've been looking for some info on the older 2007 MacBook Pro battery specs and stats, etc., but have been somewhat unsuccessful. Lately my MBP has been draining the battery at a much quicker pace than normal. This machine is only a year old now (however CoconutBattery says the battery is 16 months old). Still, the battery capacity shouldn't have diminished too significantly. Before I restored the Mac and installed the Windows 7 Beta, I could average 3-4 hours on a full charge. Normally, I would keep WiFi + Bluetooth enabled, an external monitor attached, several USB peripherals plugged in, and the main display would be set to maximum brightness. 3-4 hours was pretty nice considering the amount of power the machine could have been using.
After I partitioned my hard drive, the battery life was cut in half on the OS X side. Windows 7 power management was even worse. I figured that there may have been extra disk activity causing this problem. After I finished toying with Redmond's new OS, I removed the Windows partition and moved on from there. I know after I removed the partition, I was getting excellent battery life initially. Once that short period ended, it went downhill from there. The battery meter has become surprisingly accurate as of late; in a minute or so, you can easily watch the percentages drop 1-2%, which appears abnormal. I can manage 3 hours on a single charge at best, but I usually get less. I decided to take greater care in cycling the battery, in hopes of nursing it back to health, so to speak. It doesn't appear to be working so well. Enabling WiFi and other peripherals only drains more power, but turning them off again adds only 5 minutes. So when I'm using several devices at once, I'm lucky to get a little over 2 hours. Turning off menu items and background apps does nothing either.
It's been this way for several weeks now, and yet, iStat, System Profiler, and CoconutBattery all report seemingly acceptable and consistent battery info: 86% Battery health, around 180 charge cycles, and the capacity is around 4700mAh (out of the original 5500) for now. The computer believes all is well. Performance says otherwise. I'd like to think that physically the battery seems to be okay. I've cycled and calibrated it several times. I have read reviews that indicate that Santa Rosa MacBooks with new batteries have averaged similar runtimes to the ones I experience now, but I know mine has usually bested all of the reported tests. It just seems wrong for the average runtime to go from almost 4 hours to 2 when the battery is (supposed to be) maintaining the same health level. I have AppleCare if it needs to be replaced, since this drastic change in usage time is very noticeable and counterproductive for me, but it could just be the computer (or me for that matter). Is this behavior normal for a battery of this age? What should I look into? If this is normal behavior I can live with it, but I would prefer to get as much out of the one I have.
i know that its generally recommended to not overcharge batteries. i have e.g. seen several cellphone batteries going kaput within a few months since people leave their phones on 'overnight' charge.so i am wondering if the same applies for the polymer batteries in my MBP ?however, if i am not mistaken apple uses some kind of sophisticated electronic monitoring to keep a tab on the state of charge or discharge of the battery.
does this mean that there is no chance of the battery getting damaged through overcharging ?basically, what good practises can i use to ensure that the polymer battery lasts me a long time ?
I have a 2010 13" MBP that will shut itself off instead of going to sleep when the battery is drained. I tried recalibrating and resetting the SMC, as well as disabling hibernate, but the same thing happens. The computer is barely a month old. Anybody else with a 13" experiencing this? I posted this issue on the Apple forums and someone replied stating that they heard Apple is looking into it, but usually occurs with i5 and i7 machines.
View 6 Replies View RelatedMy Macbook Pro keeps shutting down before I reach zero percent battery and often when the battery still has 25% left. I am wondering if this is a software issue that may be fixed or if there is something incompatible with my hardware. I am running 10.6.4 with a 2.16 GHz Intel Core Duo, 2 GB 667 MHz DDR2 SDRAM memory bought in April of 2007. My mac was originally running Tiger, but a few months ago I updated to Snow Leopard.
View 5 Replies View RelatedI 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 have a 1st revision Macbook Pro 15" that's about 2 years and a few months old, and all of a sudden the battery will not provide power past approximately 76%. As soon as the the battery displays, 75% or 76% of the charge remaining, the laptop shuts off completely, does not warn me that my battery is low, and does not sleep or save the contents of my RAM - nothing it should be doing. The battery is only at 149 cycles as of today, and I don't have any sort of AppleCare plan. Is this something I can get replaced under a warranty, or would I have to shell out for a new battery? And is it even worth it?
View 12 Replies View RelatedRecently my battery health has dropped to 21% with only 79 cycles. I have tried calibrating the battery and have always done it at least once a month. Just this morning I was running on battery power and it shut off with 65% of charge left. I'm off to college in a month and am wondering if Apple will replace my battery even though I'm not under warranty.
I would take it to an Apple Store but unfortunately the closest one is an hour and a half drive away. Should I try calling Apple?
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.
I own the first 'remolded' revision of the Macbook released in '08 (5,1), and have had it for over a year now. Recently though, after 10 or so minutes running off just battery power (fully charged), it shuts down unexpectedly. It doesn't say the battery is low, or near low, it just shuts down. It's really annoying, I have to use the charger wherever I go. I really need my laptop so I don't really want to take it to an Apple Store and have to wait a week to get it fixed, unless it's really necessary. My software is up to date. Any ideas on what my problem is/how to fix it?
View 2 Replies View RelatedJust wondering, is it normal that when i close the lid of my MBP at low battery (2-5 percent), it shuts down completely. When i plug it in and turn it on, it goes to the reload thing where it continues your previous session.

View 3 Replies View RelatedFor the past few days, my mid 2012 15" rMBP has been powering down or sleeping while in the middle of performing tasks, and more importantly when it's ABOVE 15% charge. Just today however, I now have a red battery indication at 52% and holding.
At the time, I had an external monitor plugged into the thunderbolt port closest to the ac adaptor port. I was running Adobe Lightroom and Photoshop, but nothing else, and was not connected to the internet. I had turned wifi off. My problems continued until I plugged in. Once on a full charge, I unplugged and the same thing happened all over. Numerous times. So, I disconnected the external monitor, and thought that solved my problem. The next time I used the computer, I put the external monitor into the other TB port and did not have any issues, however I wasn't using the rMBP as extensively.
Today, again while performing tasks such as importing/exporting images with LR & PS, my laptop shut itself down. It runs warm, and fans are purring like crazy, but that's normal for the work I'm doing. Prior to the shut down, the battery read ~24%. I plugged in and woke it up. No external monitor is attached today. I am not running any other programs besides Chrome at the moment. I noticed a red battery light at 52% and it has not changed. Option clicking the indicator shows a "normal" condition.

I have a macbook pro (early 2011) And it went flat two nights ago whilst watching a movie. It was plugged in but I've been having charger issues. Anyway, now that it's fully charged, whenever i turn it on it gets to the apple logo with a progress bar (restoring the previous session maybe?), but then shuts down. I've tried a few times and its the same everytime.I suspect that it's trying to restore the last session (the progress bar - I cant recall whether that happens normally) and running into problems because of the flat battery episode. Can a session restore be cancelled?
I can still boot up the windows partition by pressing the option button during start up, its just the mac partition that wont boot. Also, I am still running Snow Leopard (what it came with, though with all updates).

I believe the mechanism utilized by my laptop to route power either from the battery or the AC adapter, is faulty. Sometimes when the battery is connected to the laptop, the battery is not recognized and the battery icon has an 'X' in it, other times it shows a charge %. Just recently with a full battery, I removed the AC adapter from the laptop and the laptop immediately powered off as if the battery was not in place.
Assessed:
(equipment age) new linear power cable and new battery purchased in september
(connection) linear connection seems stable
(battery) charges and holds a charge
Possibly linear > battery transistor issue? Repair Options?
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 have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:
1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.
Do you guys think this is either:
A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue
I already tried resetting the PRAM and SMU to no avail.
