My 2009 MBPro is suddenly Powering off

At very random occasions it will suddenly dim, then tell me to power off by holding the power for 5 sec-etc.
It has done this exactly 5 times now. When it happened 2 weeks ago, I ran Onyx thru its paces.
Today, it has happened twice. When I run the report on a reboot, it tells me it had a Kernel panic.
I sent the reports to Apple. Just wondering if there is an obvious fix I am missing?
Thanks, Rob

Welcome to Apple Discussions!
Kernel panics are a sign of a possibly much more serious condition. Backup your data*:

And try to use this guide as to what may be causing them*:

Also if you have any log files, the process it is panicking on, or kernel extension (kext file) mentioned first, may be where the problem resides.
They are found in the Console application.

My Canon MX892 suddenly powered off and will not turn back on.

My Canon MX892 suddenly powered off in the miccle of a print job and will not turn back on.

Reset, hold both home and power buttons until the iPhone begins to restart, usually about 10 seconds time. If still problem, connect iPhone to Wall Charger and Reset, this can take about 20 seconds of holding both buttons while on charger.

Equium A300D suddenly powers off during use

I just got an Equium A300D about 3wks ago and it suddenly powers off during use.
What can be caused this?
Though it doesn't do it frequently but am still very concerned.

Sounds like its overheating. My previous laptop did a similar thing.
Is the laptop used in a dusty environment? Perhaps there is dust buildup in the heatsink.
When you use the laptop, are the vents covered by other objects?
Otherwise if its not an overheating issue, and you are using the original Toshiba AC Adapter, bring the laptop to an Authorized Service Center for repair.

865G Neo2 suddenly powers off and won't reboot

I originally posted this in another topic but I guess I should have started a new one so here's the original post:
Motherboard: 865G Neo2 (MS-6728) Ver 1.(latest bios update 2.50); Intel Pentium 4 2.40GHz Northwood; Hitachi 80Gb hds722580vlat20; PowerColor ATI Radeon 9200 SE 128Mb R92LE-C3S (identified in windows as ATI Radeon 9250); 2GB DDR no-name ram; Macron MPT-400 400W power supply; Windows XP Professional SP2
Power supply stats:
+5V : 35A
+12V : 15A
-5V : 0.5A
-12V : 0.8A
+3.3 : 22A
+5VSB : 3A
All drivers in windows are up to date.
Problem is that the computer will just suddenly turn off. If you try to turn it on again it won't turn on. Removing the bios battery does nothing. Only way to make the computer boot again is to turn the power supply off with the switch on the back, wait a little while and then turn it back on. Very annoying as this is my work pc so the computer just suddenly turning off can be a real problem making me lose work etc. It even caused windows to become corrupt once not even allowing me to go into the recovery console to try and fix it. Had to do a repair install to fix it.
Any suggestions as to what would be causing it? I can only imagine that it's a MB or power supply problem. The fact that I can turn off the powersupply wait a little while and then am able to boot suggests to me that it's the motherboard. Some capicitors have to discharge and clear memory or something before the system will boot again. I'm at a loss.

Well the computer ran all day yesterday without dying once. Then this morning it died a short while after turning the computer on. So I looked around for another PSU and put that in. Unfortunately it's only rated as a 300W but I noticed that it has about the same max power for the combined 3.3V + 5V output being 200W compared to the previous 210W. Anyway even though it is a less powerful PSU I figure that the system I'm using isn't doing that much intensive work so it should be fine. So if this one also exhibits the same problems as the last one I will conclude that it's the motherboard and not the PSU.
Problem is that it will die just randomly whther it's under load or not or even just sitting doing nothing. So even if it doesn't die again today it doesn't mean that it's fixed. Ohwell... I'll tell you how it goes.

K9AGM3 suddenly powers off

Hi guys. I need your help with my K9AGM3 mobo. First my specs:
Motherboard: K9AGM3 MS-7367 V1.1
CPU: AMD Athlon X2 5600+
BIOS: A7367AMS V1.4B1
Memory: OCZ PC2-6400 P-800 X2 (2 gigabytes dual channel)
Power: Sentey ATX450-P4
Video: Built in
Hard Drive: WDC WD32 00AAJS-00B4A0
Other devices: DVD Burner, USB mose, USB keyboard, UPS.
This mobo worked just fine for a year or so, using XP Pro SP2, then I switched hard discs and installed XP Pro SP3.
Since then, from time to time (say 1 time every two weeks or even one every month) the system totally and suddenly shut off. No BSOD, no "Windows closing" alert. Just shut off.
I'm still unable to force this to happen, and since the power off is so sporadic, I have problems trying to do trial & error, but I checked:
Is not a temperature problem
Is not a CPU usage problem
Contacted OCZ, memories are fine and they are not underpowered
Sentey power supply is not the best on town, but should be enough for this system, also, it worked fine before the update
Updated/reinstalled drivers several times
I believe is something related to network usage and/or sound usage: *Seems* to happen when I'm stressing the lan/sound, say, chatting using Skype while listening to a radio stream, still, there is nothing I can do to force it to happen. In other words, I'm not sure of anything
Also, could be a power supply or power button malfunction, but before I bought a new case, I want to hear other options
Thanks in advance.

There aren't that many devices that can and will shut down a system automatically
No, they aren´t. At first I thought that was a faulty USB port doing some sporadic shortcut (sometimes the port was not recognized), but turned out that the USB cable was a little loose and now works OK.
Temerature is usually around 30ºC, I have an alarm on 50ºC or so, that still never triggered since I have this mobo (more than a year). Also I have a CPU history on screen all the time, and an alarm when the CPU hits 98% usage.
About memory strain, I contacted OCZ about this, because this mobo is not capable to give the 2.1v needed to use this memory at its recommended timings. They say that if the memory didn't give BSOD or crash apps, they are OK and the problem should be power or motherboard related.

X230 suddenly powers off

I have been using my X230 for last two years without any problems and it still works fine except for one thing: very recently I have experienced a sudden power off a couple of times. I don't remember whether it was plugged but my battery is perfect for sure. While operating normally, the power suddenly went off. So I had to reboot it. This happened around 5 times last couple of weeks.
I realized that I have never done a system update since I purchased this so I tried to do that but it doesn't work. (See my another post below for this issue.)
Any help would be greatly appreciated!
Solved!
Go to Solution.

I am experiencing a similar problem with my 2 year old ThinkPad x230 laptop.
In my situation, the computer goes completely dead instantly on a random basis. It is like the power supply just disappeared. No attempt at a normal shutdown process. Just instantly dead with black screen and no indicator lights..
In my situation the problem happens regardless of whether the computer is operating on battery only, battery + A/C supply or just A/C supply. (Just in case I recently ordered a new OEM 44+ battery which has not arrived.)
I have completely updated WIN 7 64 bit Pro, all drivers, and Lenovo Solution Center software.
I scanned for viruses and malware using Norton, Norton Power Eraser and Malwarebytes: all is shown as OK.
I replaced the 180GB SSD drive with a new Samsung Model 850 SSD 500GB. Same problem.
Ran every hardware diagnostic tool I could find on system checking SSD, memory and all other hardware. All reports as fine. CPU temperature is 45-52 degrees C max. SSD temperature is about 34 degrees C. No noticeable hot spots on case.
Updated BIOS. Same problem.
Disabled hibernation. Same problem.
(Perhaps related is a message from Lenovo Solution Center that a hidden (non-lettered) partition on the SSD is 95% full. I assume this partition, which is labelled "Data" like the D:/ partition, is some sort of system related log or backup separate from the backup stored on the D:/ partition. I cannot find any solution on the Lenovo website explaining the purpose of that hidden partition or how to expand it beyond the current 99.99MB size.)
Any suggestions?
Thanks.

MacBook Pro July 2011 edition suddenly powered off

Last night after using my MacBook Pro for 6 hours plugged in for the most part, I went to plug my Iphone USB into the socket and it went black. It shut itself off and now won't turn on. The green charge light dimmed off moments before it turned itself off.
The battery has been hungry for a long while as after charging to full 100% it would eat up power rapidly.
I guess my only option is to take it to the apple store
I am wondering as to what happened?
Could it be the battery? I'm out of warranty so I hope it won't be a heavy cost to fix
Thanks
Rich

1. The Genius will tell you the cost of the repair before having to pay for the repair. Moreover, you pay for the repair after having your Mac repaired.
2. Correct, but as I read, it looks like the hard drive isn't damaged so you shouldn't have lost anything, because this problem is different. Apple won't modify the hard drive, but to make sure, ask to the Genius about it when you take your MacBook Pro

My computer will work for a while and then it powers off.

I have a macbook pro. Just today I have had problems with it all of a sudden powering off and I have to restart it. When i do, it does it again. I have updated all of the updates but I have never had this problem and don't know what to do. Has this happened to anyone else?

Yoga 11s powers off in some 3d games, but only on battery!

I have had my Yoga 11s for less than one week, and I love it, except for one strange problem. When I'm running certain 3D games (only when on the battery), the computer suddenly powers off with no warning. If I am plugged in, then this doesn't seem to happen. I am able to run 3DMark all the way through with no crash, and Mirror's Edge and Awesomenauts run just fine.However, some 3d games such as Trine 2 and Microsoft Mahjong cause this shutdown to happen.
So far, I have tried: updating the graphics driver to the latest version (from Intel), updating the chipset driver (from Lenovo's site), updating Intel Rapid Storage Technology Driver (from Lenovo's site). I have also updated the Lenovo Energy Management Driver. I've tried tweaking various power plan settings as well, but I'm mystified. It seems like an overheating issue, but why only certain games, and only when on battery?
I'd love any pointers for solving this. I love this laptop otherwise, so far.
*update* The same thing happens with Dead Space 3. Graphics set to low, and vsync is turned on. Laptop powers down with zero warning on battery. Seems to be running fine when plugged in. Are the fans not being used to their full potential when the laptop is on battery? Anyone with any ideas????
Solved!
Go to Solution.

I believe that I have solved the problem. After further observation, it seemed that the fan was never getting activated at full speed on battery, as it was when plugged in. This would logically lead to overheating. I downloaded the newest driver for the "Intel Dynamic Platform & Thermal Framework" from Lenovo's website, and this appears to have fixed the issue! I seem to be able to run Dead Space 3, Microsoft Mahjong, and Trine 2 on battery without a shutdown. I will test more extensively and post a confirmation later.
I hope this might help someone else, if anyone runs into the same problem.
On the driver download page for the Yoga 11s, look for "Intel DPTF Driver".

MSI GTX 770 LIGHTNING - Unexpectedly Powers Off During 3DMark Demo (Ice Storm)

I run the 3DMark demo (I believe Ice Storm is the benchmark) on my PC containing this MSI GTX 770 LIGHTNING and at about 15 seconds or so, my PC suddenly powers off. I know that at least somebody else has experienced this issue before, but is this a common/semi-common problem? Is it something to be worried about? If I were to run other things (games, benchmarks, etc.) fine but still have problems with this demo, would that be indicative of an issue with the demo, or an issue with over-stressed hardware that still needs to be RMAed?
All other benchmarks runs fine, like even UNIGINE HEAVEN or games are now stable. PSU IS:
Be Quiet Dark Power Pro 1000W
I7 3770 3.5
I even found somebody with similiar problem , look:

I simply can't get past the 1:38 mark without my computer fully turning off by itself during this Ice Storm video benchmark. I quickly checked the temps right after I turned my computer on after this crash and they didn't seem anything out of the ordinary. So, what do you think my problem is?

My iMac20 powers off by itself and won't switch back on

I'm sorry this is a bit of a saga but I'm at the end of my tether with so will be really grateful if anyone has any experience of this issue and can give me some help?
The problem started in May when, after an hour or so of use, my iMac 20 suddenly started to turn itself off and wouldn't turn back on again until the following day. This happened around half a dozen times so I took the machine to the local Apple store and was told that it was probably the thermal trip and if I removed the power cord and left it disconnected for a while, it would power up again more quickly. That evening when it cut out, I followed the advice I was given and removed the power cord from the back of the machine but it made no difference and the machine would not restart until the following morning. Back to the Apple store I went and this time they took the machine in to the workshop; a day or two later I was told that they had cleaned out the fans and tweaked some software and had run it successfully on the bench for several hours with no problem. After paying £49, I collected the machine, took it home, ran it for an hour or so and off it went again and as before, refused to turn on. Back again to the Apple store; "Had I reloaded the operating system?" Well no, because I hadn't been told that I needed to. And anyway why would I... surely the thermal cut-out was a hardware issue? The response was that the problem was definitely software-based and nothing to do with overheating or a faulty power supply unit (which was/is my favourite candidate for villain of the piece). So off home I went, backed up my stuff and ran Disc One successfully and started running Disc Two. After about 20 minutes into Disc Two the machine did its usual trick and powered off, and I went looking for a bottle of wine.
Back to the Apple store. The guy controlling the 'guest list' for the Genius Bar said that if I wanted to return the machine to the workshop that day it would be considered a new incident and there would be a further charge for any repair work. However, if I made a fresh appointment (for a couple of days later) then the work would be done as part of the previous 'repair'. Somebody at Apple really needs to look at the way the stores deal with dissatisfied customers.
So, Saturday the 11th of July arrives and I head back to the Genius Bar for my free appointment. I explained to a very helpful guy that this is my fifth visit and I would like to get to the bottom of the problem. He referred to the tech person who dealt with the original workshop repair and she came out to explain that the issue is caused by 'something' lurking in my Library folder and that if I wipe my hard drive and re-install the OS from scratch but without the Library folder, the problem should be solved.
I spent Sunday wiping the hard drive, running the OS discs and then reinstating my iTunes, photos etc and waiting for the machine to turn itself off - but it didn't! I left my external hard drive returning all my files and documents overnight and when I woke up on Monday, everything was still up and running... bliss!
Then, this afternoon, after downing loading a music file in flac format, I found that it wouldn't go into iTunes without the help of Fluke software. I downloaded the Fluke stuff and then as I dragged the flac file into iTunes - boof! The machine went off and won't switch back on again.
So finally... has anyone seen any similar behaviour with their iMac and was it caused by software or hardware? And if it is software that's causing the problem, why can't I switch the machine on again immediately?
,

Amsys plc, the company Apple uses for off-site repairs returned my iMac20 today and the accompanying advice note states that the fault was resolved by replacing the power supply unit. I am really grateful to Apple for finally getting to the bottom of the problem, particularly as the repair was done free of charge, although I had already paid £49 for a useless workshop investigation at the Kingston store. The service given by Amsys was exemplary... the collection and return of the machine was carried out at the times promised and whenever I contacted the company by phone, each person I spoke to seemed to have knowledge of the repair without having to refer to the case notes (and none of the 'press 1 for service, 2 for sales...' rubbish).
So once again BDAqua, many thanks for suggesting I call Apple... it's just a shame that the staff of the Kingston store refused to accept what was obvious to me.

Windows (7/8/8.1) moves everything to primary monitor after they are powered off.

When using multiple monitors Windows moves all open windows and apps to the primary monitor after they have either gone to sleep or been powered off. I have been looking for 2 months now trying to find a solution. My current setup is running Windows 8.1
with an AMD Radeon R9 285X and the drivers are current. However I just switched from Windows 7 a month ago, and I changed from an NVidia card 3 months ago, all with the same result.
This is getting ridiculous Microsoft. This issue has been reported since 2009 and I have not seen a proper fix yet. Please don't bother telling me to update the drivers, I've done that, with both cards and in both OSs. The only solutions I've read
about involve using questionable hardware measures in order to fix a "feature" Microsoft is imposing on people. With more and more industries moving to multiple monitor setups this seems like a poor decision on Microsoft's part. Somehow, forcing
people to leave their monitors on constantly in order to make them work properly seems a violation of energy star compliance.
The following are just some of the threads that relate to this topic in one way or another, all run my Microsoft and none with a proper fix, only MS saying its a feature, or update the drivers, or some other none helpful answer.

Hi,
As mentioned in this link (and this has been already mentioned in the link posted above)
http://windows.microsoft.com/en-US/windows-vista/Understanding-multiple-monitors
When you disconnect the additional monitor, the original display settings are restored to your primary display. In addition, all open files and program windows are moved to the primary display. The next time that you connect the same monitor, Windows
automatically applies the display settings that you used the last time that you connected this monitor. (same in OS Windows 7\8\8.1)
According to your description, the monitor is automatically disconnected when it has either gone to sleep or been powered off that causes the annoying issue, If possible, I suggest you check whether there's a "source detection settings"
(or something like this) for the monitor, set the monitor always active as a alternative solution.
