MBP Shuts Off

My MBP shuts off (not down) abruptly when doing processor intensive tasks. It has happened when iPhoto was rebuilding the thumbnail cache, when I try to run some dvd folders through mediafork, and only once when importing a CD in iTunes. Ripping dvd's is fine, as well as normal activity in iTunes, Mail and Firefox.
I thought it may be heat related so I left it off overnight and tried to convert a dvd in mediafork immediately after logging in but it still shut off. It was still cold so I'm not so sure it's overheating.
I had the logic board replaced two months ago for the whine issue and that's when it started happening.
Already tried fixing permissions, resetting that thing where you have to remove the battery (sorry, it's late), removing the extra 1 gig memory chip, recalibrating battery, etc.
Any suggestions?
PowerMac G5 Dual 1.8, MacBook Pro 15" 2.16 Mac OS X (10.4.9)

Note the exact time it shuts down and check your system logs in your Console application for clues. Also, run your hardware tester. It sounds hardware related though and you will need to get it looked at again.

Please Help! MBP shutting off when plugged in, now not recognizing MagSafe Adapter

I started seeing this problem a few weeks ago, my MacBook Pro just shut off spontaneously while watching a video full-screen. I turned it back on and the problem went away for a while. But now, the shut-downs happen more frequently. It doesn't matter if the MBP is running off of the battery or if its running off of the AC cord, it will just shut off. No warning. No standard shut-down process, everything just stops and a balck screen shows up. After it shuts off, it takes a few seconds to get it to restart, and when it does, the computer's date and time will be reset to some date in 2000. Very strange, I've had this computer for a year and I know people with the same model that have had no such problems. The battery is at 168 cylces (I use this for school, so it was being used everyday throughout the last two semesters), and the Condition is listed as Normal in the System profiler, so I doubt the problem is with the battery, but I could be wrong. I've seen posts about the RAM/PRAM causing the date/time resets. Nevertheless, the MBP has been running normally on the battery, battery life is still the same length of time as it was when I first got the computer, and runs smoothly. Up until last night, the AC MagSafe Adapter was still working, so I only used that as the power source. Everything was fine, but the MBP shut off once or twice while it was plugged in within the last month or so, but the AC would still have a green light, indicating the computer was still recognizing the power source. Now, I can't get the MagSafe to be rocognized at all. The computer is running on battery only, and I've tried resetting the SMC, but I'm unsure if it worked since the MagSafe is still unrecognized. When its plugged in, the System Profiler says it is not connected and not charging.
I'm running on Mac OS X 10.6.8, a 2.4 GHz Intel Core 2 Duo, with a 4GB memory (of which less that half is used). Computer usage is low, so its not like I'm running several programs at once, at most, its two or three at a time, for short periods. My MBP is a 13" aluminum body, doesn't seem to be overheating, has worked fine after long periods of being on and getting hot, I always let it cool down after I feel it getting too warm.
Please help if you can! Thank you!

Mbp shuts off when...

hi all,
My mbp shuts off everytime I unplug the ac. In "istat" and "about this mac", my battery is diagnosed as healthy. The only thing that I see in "about this mac" that might be causing this (honestly, I have no idea what this means) is this.
Hardware Configuration:
UPS Installed: No
Its at the bottom of the power section in about this mac. Whats a UPS? should this be installed? if yes, can someone tell me how to install UPS?
mbp Mac OS X (10.4.9)

That "No UPS" should be nothing to worry about. I have the same setting in mine and there is no problem.
On the other hand, if the battery is failing to supply power, that might be one of several things and, presuming your MBP is still within warranty, it needs looking at by Apple.
As a thought, why not check the relative settings for Power and Battery in "Energy Saver" preferences (in System prefs)?

MBP Shuts off when there is slight movement

Hi,
Today my MBP started acting weird. I've never had this problem before. If I tap it, or move the lid it randomly shuts off. I'm afraid to type to hard b/c I feel like it will just shut off with any slight movement. I've reset the SMC and done a bunch of other troubleshooting.
Is this a software issue or hardware?
I feel as if there is a sensor loose inside my mbp which is causing it to suddenly shut off.

Bound to be hardware, Rudy.
Does it occur both when running from battery and from the mains?
Is it definitely shutting right down rather than falling into an unwakeable 'sleep"? (If it is shutting right down then a single press of the power button is all that is needed to restart, rather than holding the button down for a few secs and then pressing it again.)
What model is it?
Cheers
Rod

My MBP shut off after plugging in 3rd party USB and won't start up again

After I plugged in my phone to my MBP with a 3rd party USB cable it shut off and it never turned back on. I read online to wait it out and let the battery die and then plug the MagSafe charger back in. I waited about 24 hours and it still won't turn on. Should I remove the battery and re-insert it?

Try resetting SMC first:
Reset SMC
http://support.apple.com/en-us/HT201295
Reset NVRAM
http://support.apple.com/en-us/HT204063
Have you had battery issues recently?
"Should I remove the battery and re-insert it?"
If the SMC reset doesn't help then that's the way that the SMC was reset when you could remove the battery. We've had luck unplugging power adapter and the battery, pressing the power key and replugging the battery after a few minutes.
Late 2011 Macbook Pro refuses to boot. SMC reset doesn't work
"Thanks for your help. Disconnecting the battery and leaving it disconnected for minutes rather than seconds did the trick. I was able to then reset the SMC and it's fine now. Ordered a new internal battery as the one in use is 3 years old now. Maybe that will help."

MBP Shutting off - DVD related?

4 times today while on battery my MBP has shut off. Oddly enough, it seems to also be related to the fact that I burned a CD for the first time. Has anyone else seen this behavior? My battery doesn't look like it's bulging at all. I also installed 10.4.7 last night. My serial number starts with W8609.

John,
Sounds a lot like the symptoms of a failing battery.
The bad batch of batteries in early MBPs would cause
the MBP to shut down without warning, especially if
the battery is low. I'd contact Applecare and I'm
sure they'll send you a replacement.
It's wierd, though - I'm one week outside the "window" (which on the articles I read was up to serial numbers W8608 and I'm a W8609). They had me reset the PMU. If it does again I'll got to the Apple store and see if they'll get me a new battery. If it still keeps happening then I'm hosed. I hope my ThinkPad for work ships soon otherwise I can't be without my MacBook Pro for a week...

MBP shutting off when battery still at 20-30% charge..help a newbie

I have had my MBP since last march but I have to admit I am a casual user and this is my first mac (meaning I am pretty clueless). I have had zero problems with my MBP until now...
Over the last several days my MBP has been shutting off unexpectedly as if it is out of battery, but with no warning and the battery indicator says it still has decent charge (usually 20 to 30%). If I plug in the charger and turn it back on it works fine and the charge is where it was when it shut off.
Does anyone know why it is doing this? I have been only using Safari when this happened. It is very frustrating to unexpectedly lose my place in whatever I am doing, and I want to make sure something is not wrong with my computer.
MPB Mac OS X (10.4.8)

Have you calibrated the battery recently (or ever)? If your battery isn't calibrated then your computer can think that there's 20-30% left when in fact it's empty. Also, there's a firmware upgrade to fix MBPs that shut down randomly(that is if it's not a battery problem). Info on the firmware can be found here:
http://www.apple.com/support/downloads/macbookproefifirmwareupdate12.html
and info on calibrating the battery can be found here:

Hope this helps.

MBP shuts off when not plugged in (yet battery is fully charged)

This is the 3rd time I've suffered from this problem.
The problem lasts for about two days then seems to go away for a week or so.
When I leave the MBP charging for a few hours, then disconnect the power, it almost immediately shuts off (no warning, no error, no sleeping).
While disconnected, if I try and turn it on, I hear the boot sound, but then it shuts off again - the monitor never turns on.
If I connect it back to the power it turns on and boots fine.
My parents also have a brand new MBP, and I can avoid the problem by swapping batteries.
I therefore think my battery is faulty.
What else can I do to test the battery functions?
Thanks,
-Vijay

This started happening to me a few wks ago. My MB Pro would just go blank and shut down for no reason, while using it unhooked from the power cord. I could restart it, but it would shut down within a few minutes. The battery showed 60 to 70 %. Looking up on this discussion, I found numerous others who have had this problem. I called Apple support, but could not get to a person, they work only 6AM to 6PM in the US. So, today, I took it in to the Genius Bar, here in San Jose, CA. His first reaction was, Oh, you do not have Applecare. I told him about the battery problem reports on this discussion. He feigned ignorance of the problem. Next minute, he turned to me and said he will replace the battery free of charge! My MB Pro is 17 months old, and I do not have Applecare. So, all you people with this 'sudden death syndrome' please go into the store, or call Apple and claim what is due.

MBP shuts off randomly when not on charger

I've had my MBP for a while and for the last year, when my laptop isn't plugged in, it shuts off compeltely without warning. Just wanted to know if it's time for a new battery or a hardware problem.
Battery Info:
Full Charge: 5330
Remaining: 5208
Amperage: 0
Voltage: 12294
Cycle Count: 81
And of course, this is while it's plugged in.

Hi wpetraska;
When I got my MBP, I was having the same problem. Since it was brand new, I took it into the Apple Store. They looked at it and told me there was fault with the logic board. It would have to be replaced. Two days later I got it back and it has worked great ever since.

MBP shutting off by itself = epic time on hold!

After months of my MBP shutting down randomly a half-dozen times a day, I called Apple Care today; when I explained that it was STILL shutting down after having the hard drive, heat sink, and motherboard replaced, the rep said "We'll replace your laptop. Let me bump you up to Level 2".
That was FOUR AND A HALF HOURS AGO, including me being rerouted to a dude named Bob in the Testing Lab who said "Uh, you're not supposed to call us back here. We're in the back room."
I'm still on hold, going on five hours on the phone. Is this a new record? Should I give up?

I have exactly the same issue with iPhone 4. If the phone goes into sleep mode it then switches itself off and is always difficult to restart. If you google this issue then you will find it is a common one that Apple refuses to acknowledge. It is not practical for me to visit a store - Apple should be obliged to send replacement phones rather than the onus being on me to go to them!

MBP shut off by itself, cannot connect after re-start

Hi All,
I'm writing because I know some wonderful person out there, will help this badgered father get his daughter back on line. Earlier this afternoon, my daughters MBP13 shut off all by itself (battery was fully charged). She was not able to get it restarted for 20 minutes. Finally upon re-start, all of the normal settings were missing. Such as the date and the time. It was re-set to 2008. Since then, she has not been able to get on to our home wireless network. The others (1 iMac and 1 MBP) are all fine. I did not have an appointment, but I went to the local Genius Bar. They were too busy to help me, but allowed me to start the MBP and checked it quickly on the stores' network. It found the network and signed on fine, so I know it's not a hardware related issue. I've gone through all of the diagnostics and help screens and cannot get it back on line. I've also re-started my Verizon FIOS router three times, but all without any luck. Can anyone help me get this back on line and peace back into my home?
cheers,
Jack

Try this: Shut down your computer, take out the battery and power cord and pres the power button for about 10 seconds. After that, reseat the battery (and power cord if necessary) and turn on the computer whilst holding down Command-Option-P-R. Wait until you hear the startup chime AT LEAST once after the initial chime. What you just did is a reset of SMC and pram.
After that calibrate the battery by fully charging it, use the computer on power supply for at least 2 hours. Then unplug it and use it off battery power until it completely runs down. Let it stand for at least 5 hours and plug it back in.
Hope this helps

MBP Shuts off Randomly when not plugged in

So, I've had a 2007 MBP and been very happy until just now.
My computer has started randomly shutting off. Not shutting down, but like "click" off when its not plugged in. This happens at different times, sometimes 5 minutes after its unplugged, sometimes 15, but it will.
Any ideas? Anything I can do? I don't really want to buy a new one because this one works just fine other than that.
Thanks

Seriously, look on the first page of this forum and you'll see other threads already started on the subject. No-one has a solution as yet, other than replacing the battery, even though it seems to be a software update (Snow Leopard or otherwise) that's the culprit.

MBP shuts off randomly

My 15-inch MBP (bought May 2009, running 10.5.8) has recently been shutting off randomly, sometimes upwards of 10 times a day if I am using it a lot.
I first suspected this as a battery problem, because the only way I can keep it from shutting down is by keeping it plugged into a power source (it has never shut down when plugged in). However, I have a second battery that I bought in 2010, and the exact same problem occurs regardless of which battery I have inside.
Although sometimes the shut offs are random, sometimes it will happen if i sit my MBP on a desk not-so-gently (but not hard either), or if I drop something not-so-gently onto the area below my keyboard. Also, it almost always shuts down when I close the lid and put it into my backpack.
I don't know too much about the interior hardware, but my best guess was there is a faulty area where the computer power attaches to the battery source, and when somethign disturbs that connection then the computer shuts off?
Any thoughts?

MBP shuts off when using Skype

I recently downloaded skype to stay in touch with family who don't have a .mac. However, now if I'm not plug into an outlet and I use Skype, the MBP will randomly and instantly shut off. My battery displays full or near full life and I don't have this problem if I stay plugged in. I've updated all software and this hasn't resolved the problem and I don't have this problem when not using skype. Please Help

I checked the system profiler and the full charge capacity is 2657 and the cycle count is 107. This only confirmed my earlier diagnosis. The battery is failing. It is now happening when Skype is not on. I think it was just a coincidence that the problem appeared after installing Skype. I've also now noticed a bulge around the battery area and intermittent trouble with the track pad and button. I contacted Apple about the battery and was told I'd have to buy a new one. I'm only out of warranty by a few months and my battery was not part of the recall. Thanks for the help.

MBP shuts off when battery goes down to ~20%

Recently, my MBP started shutting off when the battery level got to 20%. No low battery warning, just shuts off like it got to 0%. I plug it in, turn it on, it boots and battery level is right around 20%.

I took it to the Apple store and the "genious" told me that cycle count is too high and they can't replace the battery under warranty. He said I use it with a battery too much. Last time I checked, I bought a portable computer, it has a battery for a purpose. When I work at a client's office I don't always have it plugged in. What does actually constitute a "cycle"? I've had the laptop for 1 year and 2 months.

Ok, so I'll tell you guys my experience with the genius bar at the Apple Store.
It was about 2:20 pm today, I walked up to the genius bar and waited for someone to come to me -- which took all of 30 seconds. So he asked what my reason for visiting was, and I told him the story about how my battery would just cut off at 30%. He then asked for my computer, so I reached into my laptop bag, pulled it out, and placed it in front of him. It was in sleep mode so we just opened it up to get started; he went to the "About this Mac" from the Apple button in the menu bar and took a look at my serial number. After about 2 minutes he said "I'll be right back." I waited for no longer than two minutes, and he came out from the back with a box in hand. He then flipped my computer over and took my battery off, opened the box, pulled out a new battery and placed it in my computer. Then, all that I had left to do was sign for it, and I was on my way in no more than 10 minutes.
What I find interesting is that he didn't even look at how many "cycles" my battery had; although, it probably wouldn't have made much difference as it was only at 17. At any rate, I asked him if there was a set of defective batteries out there -- including mine -- and basically he told me that yes, there was. So I guess since he looked at my computers serial number, his computer told me that mine was one of the affected ones.
Anyways, bottom line was it was very easy to do to get it replaced, with zero hassle. For the most part, I'm pretty happy with how the Apple Store and genius bar both opperate, much better than dealing with stores like Best Buy and the like -- in my opinion anyways.
Good luck everyone.
