MBP switches off without warning at 15% battery
After recently upgrading to 10.6.5, I was working on my MBP and when it hit 15% of battery, without warning the laptop completely shut itself off. To reboot, I had to plug it in to power up. This has happened both times I've run low, and I have yet to get a battery low warning message, or an orderly shutdown. My MBP simply shuts off. Never had a problem like this before. Any solutions? Similar experiences?
(n_n) is correct. Modern batteries are "smart devices". They have a computer chip that informs the operating system how much power is left and the OS uses that information to approximate how much time is left before the battery is drained. Based on this information the OS can tell you how much time you have left, when you are running on reserve power and when you are close to depleting the battery. As you use the computer, running on battery and recharging it, the onboard processor and the OS get out of sync and that's what you experienced.
Apple recommends that you calibrate your battery to prevent this. I've set up a repeating calendar event to remind me every other month. My wife, whose computer use is different from mine, has her reminder set for every month.

MBP shut off without warning on 30% battery
This is the second occurrence. Two weeks ago it shut off without warning at 10%.
My Macbook Pro is 17 months old and the battery has gone through at least 150 load cycles. The battery's current max capacity is 3205 mAh (out of 5500 mAh, so 58%).
Do I just need to recalibrate the battery, or is it time to buy a new one?Reset the SMC (System Management Controller) and re-calibrate the Battery, you should do this every couple of months. Your battery condition meets the terms for a free replacement ...

MBP shuts off without warning on battery...
In the last 3 days my 17" MacBook Pro shuts off with 17 mins left of battery. It doesn't give the running of reserve power warning it just shuts off. I bought this MBP in August 2007. I have reset the PRAM and did SMC reset. Is my battery going bad?

I purchased my MBP in 07 and the battery Model No. is A1175. It shows only 87 cycles. There is a replacement program for that model battery, but my serial number wasn't included. I still have about a year on my Apple Care so I called and, while they were quite helpful, asked that I stop by an Apple store to have someone look at it to rule out any problems with the computer's energy systems.
So I stopped in last night, and the tech confirmed it was the battery. His initial comment was something to the effect that battery warranties are only one year, but after clicking away at whatever he was looking at on the other side of the counter, he confirmed that Apple would be sending replacement free of charge. So it appears to me that this is becoming more of a widespread problem and for those running into this, I would encourage you to complain firmly to Apple Care and your local store and hopefully you'll get a free replacement as well.
Good luck -
MBP Powers Off Without warning - on battery
Similar to earlier post, but happens anywhere after 70%. MBP powers off. No warning or anything.
Have changed battery. We had the logic board swapped out as well. And it's started to happen again. Any suggestions? He's on 10.5.2 now, only difference from when it didn't happen.Quite likely still the battery, depending on when it was replaced. Some users (e.g. Retired Engineer, who you'll see among the Top Users list for this forum) have reported getting four successive battery replacements under the replacement program.
Hope this helps... -
Computer turns off without warning on battery power
Starting a few weeks ago I've found that my Macbook Pro has been turning off without warning while on battery power. The first time this happened it was after about an hour of use and now it happens within a half hour or less. If I try turning it back on it shuts off before OS X is fully loaded. According to CoconutBattery my battery's health is at 97%, so the battery isn't losing overall charge capability. When I'm on battery power it says I have 2-3 hours of battery life left. Sometimes I notice this will drop between 1-2 hours after 20-30 min of use (if it'll stay on that long) but it never drops and gives me a warning of low battery. It just shuts off without warning. If I press the button on the battery after this happens I do get 4 out of 5 lights. This never used to be a problem. My computer is 14 months old. I've replaced the battery once about 8 months ago (under warranty) because my original battery was losing capacity very quickly. Because 14 months have passed I can't simply get a new battery under warranty. According to Cocoanut Battery and the Finder my battery should last near it's full capacity. I can't figure out why it's randomly shutting off. I have had all the latest updates including the recent battery patch. Any help would be greatly appreciated. I will award "solved" for a solution and "helpful" for posts that contribute to the solution. thanks!

Actually (and fortunately), that's incorrect. Apple extended the warranty for all Core Duo notebook batteries to *2 years* from date of purchase. Details are here:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
Your full charge capacity is fine (as you noted). But one of the symptoms listed on the linked page is +"Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300."+ The word runtime in there applies, so I would call Apple or make a Genius Bar appointment and head into a store. (I did the latter, they replaced mine - free of charge - 15 months after purchase, no AppleCare, and no hassles).
Hope this helps... -
Problem: Qosmio 505-Q850 turned off without warning and won't start up
The unit switched off without warning leaving only the LEDs for external power and the battery lit.
When the power button is pressed, it lights up for a moment before dying again. A few seconds later it lights up again before quitting again. While it's lit up the power LED is also lit and a slight vibration is felt from the unit.
Other than the slowly blinking lights and the slight sound/vibration, there's no life from the unit. Any ideas?Sounds like it aint charging properly... could be a break in the charger wire right before the connector or the internal power connector is bad. the is supposed to run on the charger power alone without the battery intalled. if it does not its definitly the charger or the internal connector. If it does come on with the charger alone let it run for a while an then feel the the power connector and wire to see if its hot. If it is, this can be an indicator of an break in the wire or or a bad internal connector.

My Imac will suddenly turn off without warning and then take several hours before it will switch back on again. Can anyone advise?
I like that third tag...
There's really no telling what the problem might be - you may want to try running the Apple Hardware Test (if you can) to see if you've a hardware issue. If you can't even get to the AHT, you've no option but to take the machine into your local Apple Store or an AASP and have them run diagnostics on the machine.
Sorry,

IBook shuts off without warning
Hi,
How do I solve this? My iBook's started powering off without warning -- even if the battery's fully charged. I left it on charge overnight and only got ten minutes use out of it before the iBook switched itself off.
What do I do?
iBook G4 12 Mac OS X (10.3.9)
iBook G4 12HI Oliver,
You may want to try reseting the PMU (Knowledge Base Document #14449, which covers Resetting Powerbook and iBook Power Management Unit (PMU)). Have you looked at Knowledge Base Document #300552 on My computer won't turn on (Display troubleshooting) and Knowledge Base Document #106214 on Troubleshooting Startup Issues.

My MacBook Pro turns off without warning
My MBP (13 inch, purchased mid 2010) turns off without warning. It is a 2.4 GHz Intel Core 2 Duo processor with 4 GB Memory running OS X Version 10.9.4. It happens after periods of both short and long use and has been occurring for the last few months. I keep it updated regularly. I have yet to receive a report when I turn it back on that explains the shut down. So far I have reset the SMC and PRAM as others have mentioned that it helps. No luck though. My battery lasts all day, and I don't use my computer heavily. It doesn't feel hot when it turns off either. There is simply an audible "click" and a black screen. Can anyone help explain this? It is getting very frustrating having to constantly worry that it could crash at any second.

Macbook air turned off without warning?
Hi! Last night my macbook air turned off without warning and wouldn't turn back on until I tried again this morning. A few weeks ago I had my battery and logic board replaced and since then it the screen has gone blue for a few seconds and then back to normal a few times, (in case this is related at all). Is there something I should do to make sure this doesn't happen again.
As you say it is just been repaired I would take it back to the place that repaired it and ask them to look at it.

My iPhone 3GS is constantly turning off without warning. Help?
My iPhone 3GS has been constantly turning off and turning back on without warning, but my battery life is at 90%! It has been doing this for a few days, and it doesn't even stay on long enough for me to type in my password. I have tried charging it, holding in the sleep/home button, and turning it off. Nothing seems to work. Help?
Basic troubleshooting is reset, restart, restore.
Although the issue described could be a battery or system board issue. -
Portege M200 turns off without warning.
Hi guys,
My Portege M200 has just developed a problem today. It shuts down without any warnings or info.
The event viewer hasn't logged anything out of the ordinary, I suspect that its an overheating issue because I'm looking at the cpu and gpu temps using speedfan and PC wizard and they both read the cpu temps in the 50's and PCWiz reads the gpu temp as 57. But I am getting no info on the fans is that normal??!!!??!!
Speed fan has 1 manual control for a fan (doesn't say which one, but seem to be the cpu fan) which I now have set at 100% to test it and see if it shuts down again. This has been on for about 5 mins and the cpu temp is down to 36.
I have no way of controlling the gpu fan or getting the temp down on that....
Is there any way of testing the fans/ sensors for determine where the problem is??
Can anybody think of any other things that I can check or that would cause this to happen??
Thanks Guys.I also believe this happen because of overheating. In such cases the notebook will simply switch off without any warning. Sorry buddy but I believe it is time for cleaning up. Now is the question how you want to do this. Alone or it should be done on professional way.
Your decision! -
When I run low on power my MacBook powers off without warning
I've noticed that when I'm running low on battery my MacBook will power off without warning, I'm pretty sure it used to go into sleep until I charged it.
Is just powering off the correct behavior and if not are there ideas on why it's not going into sleep?
Thanks!This seems to be a growing problem.

I had my MacBook "repaired" when it developed the problem a few weeks ago. The day after I got it back from Apple it did the same thing. THey are replacing my MacBook (I had my computer in for repairs 4 times in 4 months). Some people have gotten replacement batteries but have not posted whether that resolved the problem.
