PowerPC :: IBook Battery Charge Low - Shuts Down Without Warning

Oct 7, 2007

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?

IMac :: No Warning - Just Shuts Off - Overheating?

Sep 14, 2009

I've been having trouble with my new iMac that i purchased recently (26th of August actually). Whenever I'm doing something CPU intensive, the machine just shuts off, but usually it's not right in the middle of whatever I'm doing, it's after I close the application. For example: I was playing SimCity4 the other day, pretty old game to cause this problem I would think. As soon as I exit the game, the system shuts off. No warning, nothing, just shuts off. This will happen when i close VMs (it actually happened yesterday while I was running the VM), etc. So I've reset the SMC/PMU, PRAM/NVRAM, and I've even reseated the RAM. Still the same problem. I've taken it in to a repair center in town, hoping I'll get it back by the end of the week. Does anyone have any idea why this would be happening?

PowerPC :: G4 Ibook Shuts Down Without Warning

Dec 26, 2009

my daughter bought a used ibook g4 15" and it worked for several months before developing a maddening habit of shutting down without warning. I've read other threads about this with ibooks but they say it happens only when the battery is operating and doesn't happen when plugged in. My daughter's does it either way and will only stay on for ten or so minutes most times before shutting down. It makes the machine unusable. We've checked the power supply and the power input board. Is this a logic board issue? She paid $450 for the computer but the prices have come down and it might not be worth fixing. I can solder and can get into the logic board if someone can tell me what to do.

PowerPC :: IBook G4 Suddenly Shuts Down With No Warning

Nov 5, 2007

I was hoping you could get me started in the right direction. My wife has an iBook G4 which lately, while using a full battery, just turns off suddenly. There is no warning and it never does it when it's plugged in. The battery looks like it's almost fully charged - at least that's what the meter in the menu says, so I don't know what's going on.

Could you possibly give me some steps to go through to try and figure this out?

The first step she wants to try is to get a new Intel MacBook, but I'd like to try a couple of other things first!

MacBook :: Unable To Use System With Battery / Computer Shuts Down Hwen Start From Battery

Apr 18, 2008

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.

MacBook Pro :: No Low Battery Warning?

Sep 2, 2014

I replaced the battery in my MBP which wouldn't charge or run for more than 1 hour.  Now, with the new battery, I have 2 issues:

1--battery status in menu bar does not change.  It shows it's at 28% all the time

2--I not longer get a warning that my battery is about to run out. 

This is a drag since the computer keeps going to sleep on me because it's run out of juice unbeknownst to me.

MacBook Pro :: Sudden Shutdown Without Low Battery Warning

Nov 13, 2008

I bought a MacBook Pro September 2007, the last months I have experienced a sudden shutdown of it without any low battery warning. After browsing around the forums I found a app called Coconut Battery which I installed. This is what it showed me: What I can do to get my battery performance better? Do I have to invest in a new battery? And aren't the prices on those extreme?

MacBook Pro :: Shuts Down Instead Of Sleep When Out Of Battery

Sep 20, 2007

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.

MacBook :: Shuts Down On 60% Battery Percentage?

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%.

MacBook Pro :: 13" Shuts Down On Battery Drain?

Sep 16, 2010

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.

MacBook Pro :: Shuts Down When There Is Still Plenty Of Battery Left?

Oct 27, 2010

My 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.

PowerPC :: IBook Shuts Down - Battery Problem?

Nov 25, 2005

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.

PowerPC :: Ibook Instantly Shuts Off While Battery 60%

Oct 27, 2007

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.

MacBook Pro :: 1strev Battery Lasts Until 76% And Shuts Off?

Jul 9, 2008

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?

MacBook Pro :: Late 2007 Battery Shuts Off?

Jul 22, 2009

Recently 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?

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 :: Doesn't Indicate Low Battery - Shuts Down Unexpectedly

Mar 25, 2010

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?

MacBook Pro :: Randomly Shuts Down Now With Red Battery Indicator At 52%

Dec 4, 2014

For 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. 

OS 10.8.5
2.6 ghz intel i7
16 GB 1600 MHz DDR3
250 GB SSD (with ~25GB free)
NVIDIA GeForce GT 650M 1024 MB

I have had a Speck hard shell case covering the laptop for a few weeks, but no issues until this week.I am a pro photographer who shoots tethered on location and carries my rMBP around on assignment. It has never been dropped, or damaged in any way.

This is my current system info:

Battery Information: Model Information:  Serial Number:   Manufacturer:   Device Name:  Pack Lot Code: 0  PCB Lot Code: 0  Firmware Version: 511  Hardware Revision: 000a  Cell Revision: 1150  Charge Information:  Charge Remaining (mAh): 3455  Fully Charged: No  Charging: No  Full Charge Capacity (mAh): 7431  Health Information:  Cycle Count: 533

MacBook :: Randomly Shuts Off While On Battery Power

MacBook Pro :: Shuts Down During Reboot After Flat Battery

Dec 3, 2014

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).

MacBook :: Unable To Charge Battery - Shuts Down For No Reason

Dec 8, 2010

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

OS X :: Unable To Run System With Battery / Starts Up But Immediately Shuts Down

Feb 16, 2008

Just wondering if anyone has ever encountered this or if any experts out there know of the issue.

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.

MacBook Pro :: Shuts Down After Sleep When 2 Percent Battery Left

Feb 8, 2012

I have my mbp just 3 weeks old and I tried to calibrate the battery just few hrs ago. I continuously used my mbp until the battery level reached to 2% (the warning message showed when it was 6%). Just then I had to receive a phone call. When I was busy talking, I noticed that the mbp has gone to sleep mode but when I returned (2-3 mins later), I found it shut down. Well, I think it should have remained to sleep mode but it didn't.

Then after an hour I connected the power cord and switched on and noticed a progress bar which I saw for the first time. I have been charging it for 40-50 mins, now. Also the health of my battery keeps fluctuating between 95-100 %. istat shows this. Is this normal? So what I want to know is, Is this normal for mbp to shut down when the battery reach that low? OR there is some problem in my MBP?
