My computer suddenly shuts down!

I need some help I just got my computer I download some softwares that i needed for editing video and audio but now it has been the third time that I am working surfing on the internet and all of the sudden crashes and shuts down if anyone could help me I would really appreciate it thanks!

I had a similar problem on my MacMini -

Resetting the clock suggests (from what I've read) a PMU (power management unit) problem. Take it to an Apple Store and get them to check it out.

Computer suddenly shuts down! No "low battery" message HELP!

Ok, about two weeks ago I plugged by computer into a desk lamp at a hotel. Appearately there was a voltage issue and I heard a pop then my computer blacked out! I had to restart and when I did all my "stuff" was gone! I was able to recover my documents, etc but it was a little scary! Ever since then I have to keep my power cord plugged in. I can unplug it but it will calculate my battery life as 1 hour then will completely shut down in the next 10-20 minutes. And when I plug it back in I have to completely restart. What do I do now?

I just pasted all the info here just in case...

Connect your iPhone to a power source (computer, wall charger, etc) and hold down BOTH the power AND home buttons for about 10-15 seconds. If all goes well you should get an Apple logo. Try it even if you think it won't work, and patience is key: 10 seconds is alot longer than one might think.

My iphone4 suddenly shut down.I pluged into a charger it started vibration and got heat up in off mood. I also checked it to genius he said that its battery is ok but problem is some thing else. It is still in off mod. what i have to do?

I am having a similar odd issue. First of all this summer i took my iphone 4 to apple because my screen had quit. I could hear calls and texts coming thru but screen was unresponsive. I was a month out of warranty so the nice fella at apple gave me a 30 day warranty, then replaced my handset with a refurb. Saturday night at dinner i was on my phine and it died. I plugged it in thinking nothing of it and went to bed. When i wooe up after the charger had been on all night all i had was the black screen with the battery (red) and lightning bolt, meaning it knew it plugged in but still did nothing. So off to apple i go. They said i was out of warranty and the problem (never said what problem) would cost 170 bucks to fix. So i went and upgraded to the iphone 5 ( figured if i'm spending that anyways may as well be on a new phone). When I got home i tinkered with the old one with all the online suggestions i could find. (Cleaning ports, hard reset, putting into recovery mode, and checking indicators for water damage which there was none). Still only saw the battery symbol. I left it alone figuring i can sell off cheap and someone else can repair. Last night for kicks i plugged it in again and it came to life! It is in recovery mode (needs to be hooked to itunes to regain functionality) but showed 100% battery charge. I went to show my bf and realized an issue. If its not plugged into the wall adaptor, it wont turn on. I figured then that if i can get it plugged in and pull it up on itunes maybe it would be fine. When plugged into the computer it wont hold enough power. It thrns on shows the apple for 30 seconds, shuts off. My ending conclusion on my own is that it needs a new battery in order to be revived. Anyone think this sounds like a reasonable conclusion? Or will i be wasting money? If i can get it restored to functional, cheaply i can give to my bf (his pos lg phone is almost toast) or sell it.

Re: Restoring windows after sudden shut down during updating

Hi everyone,
Last night I was updating my windows on my Toshiba laptop, however, my laptop had a sudden shut down during the updating process.
Now when I start my laptop, I am prompted that a system error occurred and I have to insert my windows CD to continue. I never got a windows CD, and nor have I made a recovery disc yet, so is there any possible way for me to log into windows again? I am using windows Vista.
Any suggestion would be grateful.
Thanks in advance

hi dDk,
what is the first rules of using a computer?
*never touch a running system* and of course: *read the f... manual* and *make backups often*
ok this was a bit hard... but this is a common failure to make an update without saving....
now lets see what we can do....
- i assume that there is no possibility to start in safe mode...
- hdd recovery is not possible...
- you have neither a systemdisk of vista nor a system backup
now you are in operators hell....
- see a servicepartner and ask for assistance, for a small fee he is able to setup your original system
- get a vista/win7 istallation cd and install it, be aware you loose your hdd backup funktion!
- try to repair with a "system-on-a-disc" like winpe or bartpe
- try to make the hidden recovery partition visible to a os booted from cd and run recovery agent from there
if you killed your recovery partition.... bad luck

I was charging and updating my mini ipad last night when it suddenly shut down and will not turn on since then. What do I do to turn it on again?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased.

My macbook pro suddenly shuts down

Hello everyone,
I am having problems with my MacBook Pro.
It suddenly shuts down without any warning. I tried turning it on, a few seconds after the sound, it would shut down.
I read the User Manual and tried a command "press Power Button, and immediately hold down Command Option, P and R Keys simultaneously" and my laptop turns on. Sometimes it would still suddenly shuts down.
I also noticed that the mouse sometimes isn't as responsive as it used to, very slow.
I also downloaded iBoost to see if it helps.
Hope to hear from you.
Thanks.

Thanks Dominic23 for your reply.
What I noticed from the link you sent is:
Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
I bought my MacBook Pro last December 2010...will this be OK if I follow the steps? Even it was mentoned for models early 2009?
Thanks and best regards.

The Problem
The PC suddenly shuts down as if the power cord is pulled from PSU.
Detailed Description and what I've tried
The first days after I've build the system everything looked to work properly. I tried to run 3d mark 2005 and it ran without problem. Then the fourth day when I was surfing on internet and listening music with winamp, suddenly the pc shut down. This happens three times and I noticed that it depended from the audio device of the MB, in fact if I didn't play music the pc didn't switch down, otherwise after about 20minutes I played music, the problem occured.
So I thought the problem was the PSU, so I ran 3d mark 2005 for more than an hour and it ran without any problem! I was very surprised. I tried also to run Prime95, one for each CPU core, and also Prime ran without problem.
Another problem was that after about 1-2hours that I was connected to internet, the connection suddenly freezed and the OS couldn't shut down the pc, so I had to use Reset button.
After someday I noticed that the motherboard has 3 power connectors!!! I've connected to the PSU only the 4pin and the 24pin!! So I connected also the molex to the PSU. So I thought to have found and solved the problem, and for about 48 hours the PC worked properly, also for 6 continous hours, I can play music using the Realtek audio device and no more problem with connection.
But then again after about 48hours the same problems!!
So I've tried to disable the realtek device and to use a sound blaster 1024 Live! And it seems to work, I can play music and the system doesn't shut down. I've also disconnected the two 80mm fans, it seems to help.
Another strange thing is that now when I switch on the system the MB emits two short beeps. Before it emited one long beep. What does it mean? I don't understand the cause of this change.

True, the computer doesn't need that amount of power.....but....
You are miscalculating the powersupply.
Just because it states it can do 17A (or what ever figure) it doesn't do that all the time.
Here you have the details of how a PSU handles output, then you might have a clue what we are talking about:
Quote
3) Specify a low operating temperature for rated output. This is quite common, but again not often seen in consumer brochures, but rather tech spec sheets provided usually only on demand by engineers or corp buyers. A typical PSU operating temp statement is somthing like this:
0?C ~25?C for full rating of load, decrease to zero Watts O/P at 70?C
Examine what that says. Full power (let's say 400W) is available when the unit is at 0?C ~25?C. Hmmm. Think about this.
Have you ever felt air blown out of a PSU in a PC running absolutely full tilt (which it would have to do to get anywhere near 400W output) that felt cool to the fingers? 25?C airflow would feel exactly that: Cool, given that normal body temperature is 37 ?C.
So this PSU cannot deliver full rated power when its temperature goes over 25?C. OK, what happens to the max power output capacity above that temp? It decreases gradually so that by the time the PSU temp reaches 70?C, the PSU cannot deliver any power at all. So if you assume that this power drop as temp rises is linear, then max power capacity will drop by ~9W for every degree over 25?C.
Now having examined as many PSUs as I have over the last 2~3 years, I have to say there's not a single PSU in ANY PC I have ever used or examined that would not measure at least 30~35?C almost anywhere inside the PSU under almost any kind of load. And if/when it is pushed, 45?C is nothing at all, especially for or near hot running components like voltage regulators.
So let's say 40?C is a fairly typical temp inside a PSU. This 400W rated unit would actually be able to deliver a max of just 220W at that temp. Hmmm. Interesting, isn't it? At 50?C, the available power would drop to just 130W. No wonder some PSUs have 3 fans each capable of 50 cfm!!
Here's a simple fact: Really high quality PSUs are actually rated for full power output at as high as 50?C. The trick is get a hold of the spec sheets that tell such information so you can compare apples to apples. Or ask.
Source: >>SilentPCreview<<
I suggest you start reading on their site as to what they have to say about powersupplies.
As those PSU's DO NOT DELIVER the amount of power under all conditions....many people have blown their system to pieces already by ignoring the heat-factor.
That is we are telling all along, you don't need 33Amps....but you need loads of headroom when summertime temps are there.
Because then your PSU doesn't deliver near the ammount of power you think it does.
Also, split rails are far worse then single rails when it comes to that...heck a lot of so called splitrails are not splitted at all, like the some of the Coolermasters....
Do yourself a favor and get to know how PSU's work, as they are NOT what you think they are.
And to quote a bit more from the same source:
Quote
What's really interesting is that Intel has tacitly waived the 240VA limit requirement in its PSU validation program for the better part of a year. Intel maintains a web page listing all the ATX12V they have tested that "meet MINIMUM electrical, mechanical fit and functional compatibility" with Intel desktop boards and processors. For the 32 ATX12V v2.2 PSUs tested in 2005 that are on this list, 17 models are identified as having at least one output line that exceeds 240VA. And yet, these 17 models are on Intel's approved list.
According to the engineers I spoke with, the majority of these 17 models have just one 12V line. They also point out that there are another 20 or so ATX12V v2.0 PSU models on the Intel list, and none of them were tested for the 240VA current limit conformance. My sources say that if these models had been tested, more than half would not conform to the 240VA current limit because they have only one 12V line.
In the last couple of months, my PS engineering sources report, Intel has verbally informed them that the 240VA limit has been removed. A single 12V line is now "officially" approved, never mind what ATX12V v2.2 specifies.
What does all this mean? Essentially, the only potential benefit of dual 12V lines is improved safety, and this is questioned by the engineers I spoke with. There are many downsides to dual 12V lines, including higher cost and the extra headache of ensuring adequate 12V current for all the components in complex, high power systems. For the consumer who is trying to make a choice among the myriad of PSUs available on the retail market today, the most practical approach regarding dual 12V lines and power capacity is to consider only the combined 12V current capacity. (It will certainly be interesting to see how Intel handles this issue in the next version of ATX12V.)
But you better read their site, as there is way more info there regarding PSU's then any other site I know of.

My laptop suddenly shuts down even doing nothing

so i got a toshiba c660 satellite laptop. everything was good until one day when i was using my laptop, it suddenly shut down. then i try to open it again, while in the starting windows logo, it shuts down again. i tried to open it again, then the launch start up repair command showed up. i tried the start up and i can use my computer again for long hours. but after letting it rest for few hours, the same thing happened again. what could be the main problem? and what should i do in order to fix this? and another thing when i use capslock the key 4 r f and v do not function. but if i hold shift i can type 4 r f and v. is that related to the sudden shutting down? please help me. thanks in advance.

You're system inexplicably dies, do your rebooted sessions last longer if the system is allowed time to cool down before restarting.
If the system is immediately restarted after halting, does the immediately restarted session halt after barely a few minutes or even seconds?
Youre description has the hallmarks of a struggling CPU inadequately cooled by a fan bogged in dust.
An inexpensive can of compressed air might be the solution and this site along with the rest of the web is repleate with instructions and mundane tips of how to most effectively smot dust from your notebook.
It isn't rocket science, but it shouldn't be done while the system is powered on, seems obvious but the poker card in the bicycle spokes sound effect from shooting air into a spinning fan also damages the fans ability to remain useful by Christmas, perfect excuse to buy a whole new laptop.

Powerbook suddenly shuts down...

Last night my powerbook suddenly shut down while in use. After I rebooted, there was a message saying the date was set back to an earlier date and keeping that the computer could face unstable condition. So I checked under preferences > date and time but the date seemed correct.
After that I used my cloned external HD to boot into OS and ran DiskWarrior to see if there was any disk errors. While running that I got a Kernal Panic message (the power sign, w/multi-language), so I shut it down and attempted to restart, but then it had problem booting into the desktop.
After restarting, the open-source gray screen came up, asked to type in "mac-boot" to boot or power button to shut down, so I typed in the prompt "mac-boot", and then a little OS folder icon showed up with a question mark flashing.
So I shut down the computer again, took the battery out and did the power-management reset (hold down pwr btn for 7 secs). Then I was able to boot back into desktop.
Has anyone experienced sudden shut-down on your PB? I think this is the second that has happened on this PB.

my 15" powerbook has done the same thing, well at least the first part of your message. The computer shuts down suddenly and then I get the error message about the date and time being set to the wrong date, etc. i thought this had to do with the new battery received from the battery exchange.
Where is this other external battery found. Is it user replaceable?

IMacs suddenly shuts down

Hi,
Since a while my iMac suddenly shuts down and reboots.
It starts with a frame freeze, can't move the mouse cursor. After a few seconds my iMac shuts down.
I have no idea what the problem can be.
This is the report of Console when it shuts down.

Hey MagicMarcus,
Thanks for the question. I understand that you are experiencing issues with your iMac unexpectedly shutting down or restarting. The following resource provides some great information if this happens, along with potential resolution steps if it is a reoccurring issue:

Desktop Computer dc5750 shuts down and red light flashes on front of computer and won't start at all

I have a DC5750 HP Compaq Computer it is 6 years old, but I have 4GB Ram, Nvidia GS8400 Graphics Card, two one TB Hard Drives. While I tried to re-installed my operating systems it all of a sudden shut down not once but twice, I opened up the side of the computer and found that it was hotter then normal. I let it sit for a while thinking it maybe over heating after hooking it back up I turned it on again nothing happened except a beeping noise and red lights flashing on the front. Can this be fixed as money is an issue.
Thanks

T510 suddenly shut down!!!!

I have an T510. When watching a movie it suddenly shut down.
The computer is all dead now. If I use only battery or only 220V, or even if both is on. When trying to start up, nothing happens.
I have not done anything to it. I was only looking at a movie, then suddenly - pooofffff, all dead.
Anybody have an idea of what it can be?

Hello mate,
Try to remove the ram and start it. If you don't hear beeps when it start means the motherboard is dead and go back to Lenovo for the warranty, otherwise keep us posted.
