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.

New battery but couldn't work & Mac can be suddenly shut down even plugged in

Hello everyone,
I just received a so called new genuie battery for my macbook 13'' , 2008 aluminum. But mac couldn't start if only with the battery. When I plug in the charger, there shows green light, so whcih means it doesn't charge the battery at all. In addition, I have to press the start bottom for a while, in order to start the computer. By press normally, I can hear some noise seems like from hardware, but nothing happens then. It is the same sound as, when only electricity connects to mac but without battery, my mac suddenly become black screen (shut down without any notification).
Does anyone know what's problem with my mac or the new battery or both?
I really appriciate if anyone can help me with the problem bother me a lot!
Thank you.

Laptop suddenly shuts down with battery at +60%

Hey guys,
So i had my laptop for a 6 month now, it is an MSI GT683DX Windows 8.1/Updated from Win 7 HP, but recently i did a battery calibration using the offical MSI software (it just charges and decharges the laptop)
But now, my laptop would just die randomly whenever it is off the charger.
The symptoms are:
When not plugged in, it would just die randomly. It won't do a proper shutdown/sleep/hibernate, it just goes black, as if you pull the power on a desktop.
About a month ago, the windows battery indicator would be a little off, sometimes it would show 15% left, where i would get a message indicating that it is at 15%. However, if i dont plug it in, it would suddenly show a message saying it has 2% left, and then just shut off immediatly. I have fixed this by setting the low and critical battery warnings higher, and didn't have a problem since.
So i think something is wrong with the windows battery meter, for example, the battery is actually empty and windows thinks it is at 80%. So can't finish properly calibration process it will just shut down and thinks that have 0% but I know that is fully charged and forced shut down at 60% or 70% ??
Is there a way to reset the windows battery stats? Or should i let the laptop totally run itself dead, by letting it shut off, powering on, and repeating this until it would not boot?
Any help appreciated

Hi, may I know your OS is MSI OEM WIN7 HP or it is a retail version?
Have you updated the drivers, BIOS, EC after upgrade to WIN8.1?
Also you can remove MSI SCM and check if the problem still exists.
A better way to judge it is battery hardware problem or OS problem is to recover the OS to MSI factory default and check again. I guess you haven't build any MSI OS recovery DVD before, so this way can't work. Then maybe you need the help of repair center.
Hi, thanks for help
So when I buy laptop it was WIN 7 Home Premium OEM and later I see some discount for Win 8 to upgrade machine..
Now using Win 8.1 and I don't think is OS problem, force shut down start to happening after I run MSI Battery Calibrate software.
Bios is not upgraded since win 7
Drivers and scm running fine all from Msi site as well
EC updated whit last version
So laptop running fine but it seems that I make mistake when I decided to run calibrate software due to max 5-10% error on battery counter..Now its 60% :-) I am afraid that my battery is dead...

Laptop Suddenly shuts down

I have a satellite A665-S6086 laptop and I've been having a problem for the last few months where my laptop suddenly power off while viewing online videos. I have two audio drivers installed so I disabled the Intel Display Audio but no luck. Any Ideas

When you say "...power off", is this a un-controlled, instant off or is it rebooting?
Will it always immediately restart by pushing the power button or does this require waiting a spell?
Have you ever experienced this other than watching videos?
If there's no indication of anything and the machine just "blam" powers off, my first guess would be a hardware issue, maybe thermal? If it's rebooting and ONLY when watching videos online, I suspect software, possibly a driver, which apparently you are suspecting too. You might even try temporarily disabling any power-saving features you have set, just to see if they maybe affecting it.

Laptop suddenly shuts down and won't open

Hello guys! So I was using my laptop in my bed and suddenly, it shuts down and I don't know why. I thought it was low batt so I tried putting the charger but it won't charge.Please help me..

The "do something with the battery" you're referring to would be to unplug it for a minute. You can go to ifixit.com and get detailed instructions on how to do it for your model. The other thing I'd suggest, though I'm not sure it'll work with your machine in this condition, is to reset the SMC. You can try.

If your MPB is a 2009 or later, follow the "for a battery you should not remove" instructions.

Thinkpad s440 laptop suddenly shut down and will not turn back on

Qosmio X770 107 PSBY5E Bios2.10 2nd SATA3 is where? +sudden shut-downs

The history of fails:
After 2 years the second HDD (non hybrid) made noises and died a week later. System on C: (Master HDD) was running good (still was the original pre installed one from factory).
I decided to upgrade to an Samsung Evo 840 500gig SSD by cloning the Hybrid HDD on the Prime/Master channel. It cloned the original perfectly and I swapped the discs like this : The SSD stayed in the Notebook on the master channel and the still good working HDD in the box with spare parts to have a emergency disc for future....
like this it worked nearly 8 months perfectly. Then frequently an alert window opened with the message that the RAM will be full soon giving the advise to close some application. With the MS tool "Resscoursenmonitor" I had to kill the processes of svchost.exe and sometimes spoolsv.exe to get the load down by 50% and I could work on till next day the alert window was returning. I did run MS updates more frequent now because skype started crashing now every time somebody called me. At this stage sudden shutdowns (without blue screen) occurred with a followed reboot. There was no intervals for these deaths obvious - sometimes 5 times a day, sometimes not at all.
The system protocols showed at the timestamp of the crashes a mistake named " Kernel-Power ID41" which is not helpful. Hardware or Software problem ? To find this out, I took the original HDD and replaced it for the SSD. The first day nothing happened, maybe because it was mostly idle, so on the next day, I started to make the pc work with all the updates from the last 10 months including Skype, Java etc..... On the 3rd day it started crashing with Blackscreen as well and rebooted nicely.
A last final test should bring up confidence that it is a software caused failure: HDD out - and SSD back in, BUT on the 2nd SATA channel. A miracle - nothing happened for a week - it was just fine. Happy End ?????
With Samsung Magician quickly testing the behaviour of the SSD on this channel, I saw that the channel can do only SATA2 and bottlenecked the SSD.
According to the Intel specification page, the chipset provides up to 6 SATA ports at 3 Gb/s with up to 2 ports supporting 6 Gb/s transfer rates. Also the CPU should support the SATA III but where is the second SATA3 channel ?
Could it be the blue-ray-optical drive ?
Who knows where the second SATA3 channel is hiding??????
Does someone have the same Problems with this sudden shut-downs ?
Does anyone have the same Problem with Memory getting to full?
The manual doesn't give information about it - >> on the Master Channel the SSD gives, according to the Magician Tool, 6 Gb/s BUT after a few hours running Sandra2015 burn-in-test it hard crashed again.
Please apologise for this many lines - but sometimes a full picture is needed.

Dual 2.3 GHz G5 suddenly shutting down

We have a Dual 2.3 GHz G5 (production week 10/29/05, Power PPC 970 v.3.0, with 2.5 GHz RAM), running OS 10.4.8. This machine has started to suddenly shut down - like someone pulled the plug with no warning.
After turning itself off like that, we need to wait around 20 minutes before it'll start up again and keep running. Once it has shut itself off, we cannot get to the logon screen without it shutting off suddenly again. After letting it cool down for 20 minutes, it'll run again. So it seems to be heat related in some way.
I've run Temperature Monitor and iStat, and everything looks OK. Of course TechTool Deluxe didn't find anything (does it ever?).
The machine will run for 2-3 hours under load just fine, but will suddenly click and shut off at some point - even when not under a load.
I've checked the System logs and Console logs and can see nothing, except once the system log reported "ApplePMU::PMU forced shutdown, cause = -122"
The other times there was no log entry, like it shut down too fast for the log to be written.
Is the power supply going bad? Is there a temperature sensor which is too sensitive?
We'd appreciate any help or suggestions.

o maybe there is something RAM related, but I can't
imagine that RAM would shut the machine completely
off. Can it?
I believe the problem is thermal related. You may have a processor acting up. Try running Hardware Monitor once, and see what your internal temps are running.

I connected my iphone 4s that i unlocked for t-mobile. I plugged it into itunes, and it asked me to update to ios6. I accepted the download and update button. it told me it needed 8 hours. i closed my laptop. not shut down. i opened and it wants restorin?

I connected my iphone 4s that I unlocked for t-mobile. I plugged it into itunes, and it asked me to update to ios6. I accepted the download and update button. It told me it needed 8 hours. I closed my laptop, not shut down. I re-opened the laptop a few hours later, and it wants restoring?? Whats going on?! i want my iphone back! PLEASE HELP. I'M LOST!!! (I synced my iphone to my computer if that helps at all).

Yes, and, I try to restore. I have the T-Mobile sim card in it just to clarify. It will not let me get passed that, it does not accept the t-mobile sim card. i tried restoring it using wifi, cellular, and i cant get i tunes. I am scared that if i take the tmobile sim card out and put the at&t one in just to complete the restoration process that the iphone will lock again and not read the tmobile sim card, then all my hard work has gone for nothing. ( this whole process was caused by me trying wanting to empty my pictures onto my computer because i did not have any storage space left). <--- that may not be as important, but i included it just because.

My Satellite laptop (A305) shuts down when run on the AC charger/adapter

The problem is that my Toshiba _A300 series laptop (A305) shuts down when you try to run it on the AC charger/adapter_. You can boot it with the power cord plugged in and it will get to Windows Desktop and maybe a few minutes more at most before shutting off.
It will boot and _run from battery without problem_, but if you plug in the AC while it is up and running on battery the machine will normally click off instantly and reboot to the message "Windows was not shut down correctly."
The _AC adapter works fine_ reading a steady 19.19 to 19.20 volts with a voltmeter. It also _charges the battery fine when the computer is off_. I have two Toshiba brand batteries and they both work fine.
One interesting thing is that the _computer runs fine on AC when in safe mode_.
I _did a reformat/factory restore_ of Vista to assure it was not software and drivers, and still got the same problem before any external devices had been plugged in.
It has the latest BIOS and I tried resetting it to default values in case anything had gotten changed. It made no difference.
This is _not a heating issue_ because _while it is run on battery I can watch long videos_ without it shutting off. I ran compressed air through the vents just to make sure, but it makes no difference in behavior. Usually with an overheating shut-off, the computer cannot be started until it has cooled some, but these shutdowns are accompanied by an instant reboot.
I have seen on some threads that this type of problem one can work around by disabling one of the processors in Device Manager, but I don't think that is much of a lasting solution or good for the computer.
Has anyone seen this problem before and have you come with a full diagnosis of the problem and a real solution?

I have Satellite A300 and until now everything works OK.
I would like to know what happen when you remove the battery and use notebook with power supply only. Does notebook shuts down again.
If not let OS run and put the battery.
Is the battery recognized properly? Does notebook switch off again?
To be honest I cannot imagine this issue has something with software or background processes. Recovery image you got with your notebook is designed for this certain notebook mode. Recovery image is tested and I dont think preinstalled OS has anything to do with this.
Full diagnosis?
And how to do this? You know very well that diagnosis can be done with diagnostic tools only and such tools have services only. I hope you will find answers but Im 99% sure there is nothing you can do about that. Maybe you should contact service, explain the situation and ask for help.

DELL Inspiron N5110 does not Shut Down and does not wake up from Sleep

Hello.
I have Dell Inspiron N5110 which cannot shut down neither in Windows 7 nor in Ubuntu Linux. I specifically booted Ubuntu Live from the CD to eliminate the possibility that the problem is in the Windows 7. Shutdown in Ubuntu does not work either. This proves that the reason in not a BACKGROUND application in Windows that remains hanging and does not allow the laptop to shut down.
The laptop cannot wake up after Sleep or Hibernate either.
I have tried every solution that you advised to all the other people in the forum that have the same issue.
1. The laptop cannot shut down in Safe Mode either.
2. It cannot shut down even after Clean Boot Mode - all non-MS services disabled and all Startups disabled.
3. I tried changing the Advanced Power Options of "Allow Hybrid Sleep" - both ON for "On AC Power" and "Running on battery" - no change.
4. I tried installing the latest video drivers for Nvidia. This did not help either.
5. Running only on battery does not change anything - still cannot shutdown.
6. Running only on AC adapter without battery - still cannot shutdown.
7. I tried removing the AC adapter and battery and holding the POWER button for 30 seconds to RESET the laptop - did not work.
ATTENTION: I've been reading your forums all day and saw at least 10-15 reports of the same problem and not a single fixed case.
8. This is why I have not tried Flashing the BIOS to the latest version - I read other people tried that and it didn't work either.
9. I loaded BIOS default settings (F9) - still cannot shutdown.
REMARK: Changing something in the BIOS and trying to Exit once caused the laptop to freeze and I had to Power Off by holding the button for longer.
10. I ran DELL Diagnostics from Boot menu (F12 at startup) - no errors found.
11. I could not locate IEEE 1394 Adapter in Device Manager to change its Power Management settings.
Actually none of the suggestions you may give for changing something in Windows makes sense because I already mentioned that shut down in Ubuntu does not work either.
The issue seems to be either in the BIOS or a hardware problem. But which component? Is it the CD/DVD drive?
This is a new laptop.
Please advice how to proceed. If you know which component fails please tell me.

Remove the keyboard and palm rest (guide from dell shows you how) and you should see a small coin cell battery. Remove it for at least 10 seconds, then put it back in. Enter BIOS and make sure there isn't anything weird that was changed. It should work properly now. I have had this working in Ubuntu 12.04 for the last few days, with no problems.

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.

Sudden shut down battery problem, factory reset and SW update/repair did NOT help

Hello everyone, i have a "sudden shut down problem" with my Xperia Z1 C6903 too. Sudden Shutdown always happens at about 70% for the first time, after been fully charged. I cant turn it on right afterwards but if i wait 1 min. it works. However sooner or later the phone, somewhere between the remaining battery, will repeatedly shut down again. I couldnt find out what triggers it and android battery test show that the battery is ok. I am not an expert with these devices, but i hope it is a software or calibration problem? There is a similar threat which points to the solution of using Sony PC Companion Software repair, i tryed it twice and it did NOT help! edit:I havent changed the device after PC Companion repair step, thus no other Apps are running and no energy managment has been configured (stamina mode) edit 2:hidden battery info * # * # 4 6 3 6 # * # * shows:...battery health: goodbattery voltage: 3969 mVbattery temperature: 36.6° C...is there a way which gives me more details than just "good"? And what does that even mean?

Hi, I have exactly the same problem after upgtading my phone to lollipop. I tried repair from PC companion and facfory rest, but no luck.
Do you think it is Because of the battery? Never had this problem before upgrading to lollipop. The other thing I notice is when the phone suddenly shutdown (baterry jump from 50-60% to 0%), I just need to plug in my charger and wait a moment before turning it on, then here is the problem.
1. Sometimes the battery indicator shows 50% or slightly lower than before shutting down.
2. The other times, it will show accordingly that the baterry is out (1% because it's charging)
3. Most of the times, there is a message "android is upgrading...", when turning it on.
Any idea how to solve this problem?

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.
