Laptop suddenly shuts down a lot

Question: Laptop suddenly shuts down a lot

Hey Techspot, I'm hoping you can help me out with a little problem I've started experiencing. I got a Lenovo G555 just last year, and everything's been going great with it so far. However, as of about a day ago it decides to start shutting down without any warning whatsoever. It seems that this happens at random also. Some times I can keep the laptop on overnight (I like to have videos playing while I sleep) with no problems, and other times it snaps off after not even 5 minutes. Thus I can't really finish a scan with avast! or malwarebites. I haven't done anything out of the ordinary either. I don't know if it's really overheating because I keep it in a similar environment as my Toshiba laptop that has remained on around the same amount of time with no overheating whatsoever. I'm running Windows 7 on my Lenovo.

EDIT: I thought that my problem was in fact overheating, so I cleaned the fan area with some compressed air. That seems to help a little bit, but my computer still has a tendency to shut down randomly, just a lot less frequently. I checked the temperature with SpeedFan, and upon startup my core temp is as high as 80C, then cools off to about 60C when I'm doing nothing. The thing that worries me is that SpeedFan can detect no RPMs from my fan. Fan1, Fan2, and Fan3 all show 0 RPMs in the program.

I'm from India. I bought a HP 15-ay106ne laptop through my uncle in Abu Dubai on 01-01-2017.After a week I noticed that it didn't charge to 100% it reaches 99% only. After 15 days I noticed that it suddenly shuts down when the charging reaches 15% without any notification about plug-in. After few days it shuts down in between 15% and 20%.Now it's shutting down in between 36%-40% of charging. I found that the battery backup is also not good. Original backup is 10 hours but my laptop gives 5 hours of battery backup.I gave my laptop in to a HP service centre and they said it has a hardware problem. In India the spare parts are not available so please go to Dubai with your laptop.I preferred to buy it in Dubai because of its international warranty. But now they are not going to help me out of this problem.Please help me to get my laptop in good condition. And suggest me how to decrease the cycle count.

I am running windows 7 on this laptop which I bought back in April 2010. Just 30 minutes ago, my laptop suddenly shutdown without warning or whatsoever, and upon rebooting, it hung while loading windows. I tried running startup repair but nothing was found. I restarted another time and managed to get into Windows 7.

Could it be a failing motherboard?

I have a lenovo laptop 512 mb ram 120 gb hard disk. It runs nicely but suddenly it shuts off but not always, it runs ok months after months. Main problem is that at the time of formatting it shuts off so many times and after trying many times OS can be loaded then it runs for some months, then again suddenly it shuts off. As shutting off does not maintain any time, any program or any sequence it is very problem to detect the problem. Even I have taken the laptop to the service engineer but that time it does not give any problem. I am using Quick heal antivirus and updated regularly. Please help me. Thanks

Answer:Laptop shuts off suddenly

Are you blocking the fans exhausts when you're using it. It may be overheating. If the fans are blocked and it over heats, it will shut down.

I was recently having issues with the LCD backlight on my Dell XPS M1530 laptop. So I took it to the tech guy who fixed the backlight issue. But, now I get sudden shut downs while I'm working on my laptop. The screen goes white for a second before it shuts off by itself. Could it be an issue with wiring inside which the tech guy messed up? Or maybe the heat? because I notice the shut down when mostly my laptop is resting on a wooden table for about half and hour. Any advise?

Answer:Laptop shuts down suddenly

Does your laptop have the Nvidia GeForce 8600M GT installed? If so your problems are very likely a result of the nVidia Defect (I have recently had a refund on a laptop I boughgt in 2007 because of this), have a look here for info, it's a very helpful website.

Hello All, My T500 shuts down suddenly at about 2 hour intervals. I am not sure if it has to do with overheating, as when the laptop is turned back on, the temperatures are very low. I figure a hot laptop can't suddenly jump 50 plus degrees. I imagine a temperature drop would be gradual.Also, when I have experienced overheating in the past, the laptop shut down wholly. Despite being plugged in, the light will go off and I need to do a battery reset. (take out battery, plug it and hold down power button while inserting the battery)But this was as if I had shut it down. It still charges and turns back on without issue.I checked the Event Viewer and have attached direct logs.I am hoping it is a graphic's situation and I need to reinstall the driver. any more information is needed, please let me know. Also, it is not warm to the touch when it shuts off.

Sometimes my laptop suddenly shuts itself down, as if id just cut the power.

This usually happens while playing Crysis, is my computer getting to hot?
Im currently using WinXP, and it happens all the time, after about 20 minutes gaming. I used to run Windows Vista, and it happened only twice in 5 months. Anything I can do?

Answer:My laptop suddenly shuts itself down

My first question to you is this: do you notice any intense heat coming from the underside of the computer? Try playing the game in your lap, and feeling for heat (don't get yourself burned though!).

Also, what type of laptop do you have? (brand and model #)

In the past Sony Laptops were very known for overheating.

I have a Lenovo 3000 N100 laptop. It has windows XP SP2 /Suse dual boot. It's battery went kaput long ago, so I keep on running it by mains power. The laptop is three years old and used heavily.

Today it suddenly stopped, while I was working in windows. I restarted and again it went off after 15 minutes or so after booting. The booting was perfect. I tried some more times in windows it boots perfectly and then died.

I ran Linux, it was all working fine and I worked for more than an hour before it died again.

The way it dies is similar to what happens if I suddenly remove the power source, it produces a similar kind of sound that way.

Is that a power issue?

Soliciting the opinions of the experts here

Thanks in advance


Answer:Laptop shuts off suddenly

Are you running it from mains? Or from battery?

If you are running from battery, then your battery could be on it's way out. You might need to buy a new battery

Otherwise it could be the motherboard. Especially considering it's 3 years old. If that is the case, start thinking about getting a new laptop.

Hello ...
I have had a Toshiba C850-A965 laptop for 4 years
and it's been working perfectly
untill one day recently, a message poped up saying that there's something wrong with the battery and should be replaced, but it was still the same, works for an hour and a half approximately
But, I went ahead and bought a new battery, the message disappeared
and i fully charged and then started the laptop
it worked for about 15 mins and then it shut down ( like u took the plug off from a desktop computer) without any warning
when i turned it back on, it was still fully charged !!! and the shutting down happend again and again :(

Hey everyone, so I recently got my laptop (ASUS G53JW) back from the ASUS service centre and that was to replace the DC jack port as the pin broke off in the port from the charger. They didn't change the motherboard, just the port as it was a defective part and caused the pin to break off.

I have no idea what they did to my laptop at the service centre, but since getting it back (yesterday) I have an issue with the laptop....I have started to get random shut downs without any warning at all. I am just sitting browsing the internet or playing a game and the laptop powers off without any blue screen, error, or warning. It boots back up right away, except for the latest time where it powered off (shortly after I plugged in my iPod) and then it kept shutting down in the boot screen about twice. I unplugged the iPod cord (and thus the iPod itself) from the USB port and that seemed to allow it to boot back up. Funny thing has started to occur as I changed what USB port I plug the iPod into, it randomly starts charging and then stops (but the cord is still plugged in)....

I checked event viewer, as I don't get a BSOD or anything and this is what I keep getting every single time these shut downs occur:

ASUS. Battery keeps power for about 1.5 hours so I assume it's not dead. Charger charges.
1 Occurrence: I was in VLC player, charger on. Suddenly laptop shuts off, power led stays. Shut it off (properly) by keeping button then luckily turned on again.
2 Occurrence: Several days later VLC was opened again when it shut off. Power led stays, but now can't do anything to turn it on. Pulled out battery, done that 45 seconds thing, put back again. Can't turn on it just that power led lights up. Just kept it that way for hours, laptop was warm...and then all of a sudden it turned on.
3 Occurrence: Turned off doing daily things, doesn't turn on no matter how long I wait. Damn it.
Fan not working, cpu heats up a bit like it pretends to be working, dust cleaned inside. Always just that power led works when button pushed with battery or just charger in.
Whats happening?

Answer:Laptop shuts off, won't turn on..suddenly turns on

will it work with battery removed and just running off mains?
other thought is it is overheating and needs a good clean out of the fan and heatsink.

Two or three things have happened recently that make me believe that i am infected and hence am requesting help in this forum

Last night my laptop shut off all of a sudden - and i mean all of a sudden (did not boot down or warn me) like somebody flicks off a switch and the lights go out. At first I though it was the power but i was well plugged into the electricty socket and i also had battery back up.
This has happened twice before say a month back and three months back respectively but i did not give it a too much thought attributing it to freaky power fluctuation. Further, the time gaps between occurences were far and random
When i rebooted win 7 (64 bit with SP1 and completed up to date) asked me do a startup and system repair whcih i did and after a long wait i got a report saying

Answer:laptop suddenly shuts off without warning or boot down

There are only about five things that will cause a spontaneous shutdown. Overheating, bad power supply/adapter/powrer source interuption, flaky NIC, motherboard, or very rarely the processor. I'd check to see if it's overheating first and move on from there. Does it feel especially hot? Have you blown out the heatsink and fan area? Is your adapter making a good connection? Will it run on battery alone, is it holding a charge? Does it tend to happen when you are on the internet or accessing a network? The start up repair is normal, since the laptop did not get a chance to shut down properly, so I wouldn't worry about that, although it isn't good for it, of course.

I'm not sure if this is the right forum to ask about this, but I thought I'd give it a try. I bought an ASUS N56VJ laptop in February of this year, 2013. It has suddenly shut down about 12 times. This happens very randomly and with no pattern that I can see. It's not an overheating issue as I'm monitoring the temperature with ReatTempGT (and it often happens after only being on for a few minutes). This happens while running the computer with it plugged in. I managed to find an error when I checked the event viewer. I'll post the information below. If anyone can explain what's going on I'd really appreciate it. Thank you!

Hey everyone, My laptop, (it's an HP Pavilion dv6 running Windows 7) recently started having this terrible problem. What happens is that I'm doing something totally non computer-intensive when all of a sudden the screen just turns black and a second or two later shuts off. It seems as though if I don't use it for a couple of days, and then boot it up, it doesn't have the problem. But once I turn it off and turn it on again, it happens.For example, yesterday, after not using it for about two weeks, I had it on for about an hour or two before turning it off on my own. Today, I was on the internet reading an article, and had my virus software (McAfee) running a scan. I thought it was going to be okay, as if it was going to go black and turn off, it would have done so already. But, within 20-30 minutes of it being on, it did just that... it went black and turned off. I turned it on again, curious to see how long it would take to happen this time. I made it to the desktop before it went black and shut off after about 2-3 minutes. Another thing of interest is that when it is on, it is very slow, much slower than usual. And another thing. A long while back, I had set my desktop so that it would change pictures every 10 minutes. I forgot exactly when this started, but the images don't change anymore.

Question: shuts off suddenly

My pc is shutting off with no warning. I bought a used video card to play a popular game. The card needed a bigger power supply. Since putting in the new power supply (400 watt) I was unable to install patches for that game. During the installation of the patch the pc would suddenly shut off. After reinstalling my old power supply I was able to install the everything I needed for the game. I reinstalled the new power supply and the pc started shutting off suddenly after 15 minutes or so. I replaced the new power supply with another new one (same power) and the pc still shuts off but now varies in the length of time it will stay on. normally 2-3 hours but sometimes longer or shorter. It will shut off whether it is being used or not. Never have a prob turning it back on. Have left the cover off the pc and had a stand up fan blowing into the case to keep the pc cool but it still shuts down so I believe it is not a heat issue. I have done all updates for the pc (drivers/windows/spyware/virus) have done multiple virus/spyware etc scans including reg mechanic. I do not have a problem with the pc with the old power supply in it but am unable to run the video card to its full capabilities with the smaller supply. I don't believe the card is the prob because it runs fine with the old power supply other than not being able to use the better graphic settings on it.

Answer:shuts off suddenly

You may need to look into the power supply's detailed specs. You old power supply might have used only one 12 volt pair of rails with a single amp rating, but the new power supply probably has two 12 volt rails each with it's own amp rating. If combined, the numbers add up to more amperage than the one you had before, but it is not used that way on your computer. Before, you might have had say 20 amps available that all circuits could draw from (numbers for example only, not accurate) and your graphics might have taken most of it. If now you have two 15 amp circuits, some circuits will be very happy with all they need, but the one that has the graphics card on it ONLY has 15 amps to share, graphics card, and all. You probably actually getting LESS available amps for graphics with the larger power supply.In short, look for a power supply with a single 12 volt rail around the 400 to 450 watt range, or go with a 500+ wattage with enough amps on each rail to cover your video card on one side (look for 12 volt amp specs on your old power supply).

I have recently built a new system built around an ASUS A7V8X-x m/b, coupled with an AMD 2600+ CPU and 2x256 DDR 2700 RAM.The system unexpectidly shut when I tried to load Win XP, but remained stable when I loaded Win 2000. I loaded Win XP over the top of 2000, without any problems. Now when I try to load the software for my AstraMax scanner as soon as the PC tries to copy the files from the CD to the hard drive the system shuts down. Has anyone else had similar problems. I suspect the either RAM or the CPU is to blame, as the system only sees the CPU as a 2000+, not a 2600+. I have tried to set the bios manualy, but the system hangs when I adjust the chip to it's correct speed of 2083MHz (the system automaticaly picks 1666Mhz. Help!!

Answer:PC suddenly shuts down

I think but am not certain that your FSB speed should be 166 Mhz to get your CPU you be detected as 2600.If you have over clocked your FSB by too much then this could make your system seriously unstable.I dont think that the CPU or memory is the problem here.

My other computer suddenly shut down while i was playing a game. Then i smelled a burning odor. I tried turning on the computer again but it wouldnt turn on so i opened the case and felt the hardwares. The power supply and the harddrive were hot.

What happened to my computer? how do i fix this?


Answer:Computer suddenly shuts down...

have a look and see if you can see anything burnt on the motheboard.
powersupplies and HD are HOT - how hot - remember they do run very hot hence the fans.

when you turn on - do any fans spin up or lights come on - if not its likely to be the PSU.

you could try disconnecting the PSU from the MoBo and other devices and then switch on and see if fan in psu runs.

otherwise you probably need a meter to check if the psu is working.

whats the make/model of the PC and then maybe someone can advise more on parts etc.

I bought this laptop a little over a year ago and now the computer is shutting down after being on for 30 minutes. Even on battery, booted to a Linux Flash drive,  running in the BIOS or propped up to let it vent, it crashes in 30 minutes exactly. It's core i7, 8gb, 1tb HD, Lenovo U530 Touch. Any ideas about what the problem could be?

Answer:U530 suddenly shuts down

New info. It cuts off exactly 30 minutes after being turned on. Even in BIOS.

Windows XP, SP2

While I am using my laptop suddenly computer shuts down. It shows a blue screen with some details of the error. But before I could read it, computer restarts. After restart, sometimes it may function normally and sometimes it would keep shutting down. I have to turnoff the computer completely for few minutes and then it would start working normally. This can happen at any time, there is nothing specific about this behavior.
This is happenening for 2-3 months now. Then it struck to my mind to check the log files of the system. So I checked system log files in computer management. It showed "iaStor" error there.

Whats this "iaStor" error ? Is that the problem for this kind of behavior ?

Secondly, the pointer on the laptop freezes for few seconds quite often and then its released from the frozen state. When I am trying to click on a link or trying to scroll down, the pointer or grabber sign freezes and then it gets released after 4-5 seconds. Whats this behavior due to ?

I did uninstall and reinstall the windows xp, but still it gives same behavior for both the issues.

my HP Paviliion 22z was one month old. I was using it and all of a sudden it shuts off. no warning message. I thought it's a power cord connection problem. but after I look carefully, no connection issue. I pressed the power button, it started and everything looked ok. However, this happens more and more often. It is less than 2 months old, as of today. no sign of slowing down or any problem using it. it just shuts down right away. looks like there is a power failure. but when i press the power button, it turns on and works just fine. lost the data I worked on. Very annoying. Anyway to fix it?

Greetings-- my previous problem was wonderfully solved here, so am hoping help with new problem will be successful.

This past week I've suddenly developed a problem where without any warning the computer will shut off. The 'power' button on the PCU will go to an amber, and will not respond to repeated pressings. The only way I'm able to get it back on again is to cut the machine off at the power strip, then press the power button. I've run some various system scans, and nothing turns up.

I am using Windows XP, have a Gateway computer, and have NO CLUE about what is going on. Many thanks for your thoughts and suggestions. Please let me know what more information I need to provide for consideration.


Answer:Computer Suddenly Shuts Down

Hi there!

Before I can help you in any way, I would like you to give information on your computer, such as service packs are installed or not, do you get any error messages, have you been experiencing speed problems with the pc lately, or have you been fiddling with the registry( ). Thank you!
Looking forward to helping you!

I've been struggling with this for months and am at my wit's end. Any help anyone could offer would be greatly appreciated!

Basically, without warning, my computer, for no apparent reason, shuts itself off. No shut down. It simply shuts off, as though the power had been disconnected. (It might be worth noting that on starting it back up again, chkdsk doesn't run.)

At first, I though it was a random occurence and likely a hardware problem; possibly the Power Supply. However, my MoBo is set to power up the computer after losing power and, after one of these unexpected power downs, the computer doesn't start back up until I hit the power button.

I've also started to notice a link to downloading. Namely, if there's multiple downloads going on, it seems to trigger the problem. It shuts down almost every night, which is when I've got utorrent scheduled to run, and I've been able to trigger the problem reliably by initiating multiple downloads of podcasts in iTunes. It also seems to happen sometimes when web pages are taking too long to load.

It's probably important to note that the computer functions perfectly otherwise. I can tax the system with the latest games or a heavy set of video transcodes without incident, so I'd have a hard time believing it would be a heat problem.

Heres my problem:
When i start outlook and i hit F5 to check for mail, i get three spam emails (always the same ones) and then i get the message:

"microsoft windows ™ messaging subsystem spooler has encountered a problem..." etc

I guess thats the MAPISP32.exe thats necessary for sending and recieving email. So guess what happens, i cant recieve or send email. The only thing I know that I changed in the computer is that i recently disabled and then enabled again the system restore. I also recently installed SpywareBlaster. Can anybody help me?

Thanks in advance.

PS: I run WinXP and MS Oulook 97.

You may have a corrupt mail spool. Call your isp and ask them if they can delete those first 3 spam messages and then see if it works.

Sometimes it happens when i'm gaming, sometimes it happens when i don't do anything so it is a hard problem to analyse. When i am in safe mode it doesn't shut off.

I would make sure your drivers are up to date and try a system restore if you have a restore point. Also, you might be able to find our more about whats causing it by looking at the event manager for dump files. Otherwise if its not a big hastle for ya i would consider a reinstall.

My Toshiba Satellite L50-B-1HU shuts down suddenly three times last month.
Two times when the laptop was plugged to the power supply, one time when it was not (just working on the battery).

An overheating doesn't seem to be implied : the fan wasn't really hot after those 'crashes'. The laptop can be immediateley rebooted too.

Is this problem known and how to fix it ?

Hi Everyone,

Computers never cease to amaze me. Just when I think that the computer is running "the way it should be", the damn thing restarts on me. It happened a few days ago while playing Madden 2003. It happened this morning, while printing a picture, I decided to close Paint Shop Pro. For some reason, I am leaning towards this being a video card problem. More specifically, I think there is a conflict between the video card driver and several programs on the computer (i.e. graphic intensive). It has always been my understanding that a computer is SUPPOSED to remain ON until you tell it to TURN OFF. I hope someone on this amazing board can HELP ME OUT!!

Thanks In Advance,

Answer:Computer Shuts Off Suddenly


I'm assuming that you've confirmed that your CPU fan is working properly? (in case it's overheating)

Check out this site....if you don't have this driver, then try downloading and installing it:

I know that the specific error they mention doesn't really apply to you, but it might help your problem.

You could also disable your computer from automatically restarting with system errors. Right-click on My Computer, go to Properties, then Advanced, then Settings (under Startup and Recovery), then take the checkmark off "Automatically Reboot". This is probably what's causing it to reboot....while you're working on something that deals with graphics, and the system generates an error, it automatically reboots.

These are just a couple of suggestions.

Answer:PC Shuts down suddenly without warning

I'm not an expert by any means, but I guess there's no harm in having a bit of (possibly helpful) input...

It could have something to do with a faulty hard drive...I had something not so long ago where I had a lot of damaged secotrs, and copying things between disks would restart my computer (and sometimes never let it start back up)...

Have you got a spare drive you could test? Or if you have multiple drives, set the other 'good' one to the default download location and try to induce the problem.

I dont know what anyone else thinks of could be completely wrong, but I guess there's no harm in trying!

I just want to ask what problem my PC might have. My PC is old, but it is the only one I have. Lately, after some time of using my PC, the graphics went crazy with big pixels and the resolution was messed up. When I tried to print, the output has gone crazy as well. Then all of a sudden my PC shut off. When I tried to restart, it shut off again immediately.Today, as I tried to start again, everything seemed to be fine, but again after hours of using the PC shut off again.

Answer:lenovo g50-70 suddenly shuts off

hi saktani
Welcome to the Forums.
Chances are, if the shutting down problem happens on any game that you run or any graphics intensive task that you launch like watching youtube videos and/or it also happens while plugged-in / running on battery then there's likely a problem with a hardware component of the machine (e.g., the GPU).
Things that you can try:
1. Run a full diagnostic test on the machine using the Lenovo Solutions Center (see Checkup > Hardware Scan) or by using the Individual Windows Diagnostics then observe the results on the RAM, HDD, CPU, and GPU tests.
2. Download and install GPU-Z and observe the GPU temps (applicable only if you have the AMD Radeon R5 M230 Graphics)
If the machine shuts down while running the test then I recommend you consider contacting the lenovo helpdesk to report the problem.

Lately, my computer has been shutting itself off suddenly, followed by a loud high-pitched constant tone, which lasts until I turn the power off on the power supply. When I turn the computer back on, I get a blue screen that says there was an error and the system has been shut down. If I leave it off for about 10 minutes and turn it back on, it will come on fine, but eventually shut off again. A friend of mine mentioned that this may be a motherboard issue, so I'm just wondering what everyone here thinks.

Well, my Lenovo Thinkpad Edge E535 is around a year old, and it seems there are now hardware issues. Sometimes the battery is charged to 100% or a bit less and after some minutes the laptop just goes off and makes a click. That was it. After I restart it, it says it has installed some software and I should make a restart, everytime. Also there is no more low energy warning appearing (it appeared some days ago but now not anymore), it is set to 10% seems to be something like this: is there some fix?the Update Manager of Lenovo does not find a fix, the Energy Manager does also not find a firmware update for the battery Do I really have to search and download this from your website again?! Which is the correct link for the Edge E535?

Hi, Mu5ch1n4t0r
Have you checked Event Viewer to see if Windows has recorded anything related to these sudden shutdowns? If not, if you open the Start menu and search for Event Viewer, you should be able to find it (it may say View event logs, but both will lead you to the same place.) Once in Event Viewer, select Windows logs, then System. From here, scroll through the log and go to the last time you remember this issue occurring. See if there are any errors or warnings that look related to this and post those here.
Thanks in advance,Adam

My computer is having issues and I can't figure out what is wrong with it. Lately it's had this problem with just suddenly shutting off, especially when I'm playing a game. It will do it maybe once every day or every other day.

I turned off the hyper-threading function on the P4 and that stopped it for a couple of weeks but now its started up again.

Once it just suddenly restarted itself, but 99% of the time it will just shut off.

Every time it shuts off, I have to unplug it, wait for a couple of seconds then plug it back in. A couple of seconds after I plug it back in it will power up again on its own.

I'm not sure if it's the ram, power supply, software or what. What could be the most likely culprit?

Just in short: it is a typical symptom of overheating. The unit can not be cooled properly and when the temperature is too high unit shuts down suddenly without any warning. It is because of hardware protection.

Please try to clean up the unit. Probably a lot of dust in cooling grill don?t allow air circulation.

*Hello everybody*,
I'm having an issue with my L305D and maybe you could help me. I was working with my computer at my bed, and it suddently went turned off. It was maybe because the air at the botton wasn't circulating well. It is extrange because I used to do the same with my old A215 and nothing happens (maybe the more powerful processing capacity of my L305).

The strange thing with this is that afeter the shut down, the power button doesn't work neither the battery signal. My power button is back after a few minutes later but I must use the computer connected because the battery get slower to be recovery. There is any protection system for this computers? is this normal? The computer is realatively new, I'm really sad because I love Toshiba computers and I also love work at bed.

I hope you can help me with this issue or made some use recomendations.
Thanks for your help.

Answer:Satellite L305D shuts down suddenly

Many people make this mistake and block cooling vents at the bottom.
To be honest I can imagine your notebook reached critical hardware temperature and simply switched off.
Other way one thing is not clear to me. Was the battery completely empty when notebook switched off? Inside the notebook there are several temperature sensors and when the critical temperature is reached notebook will be automatically switched off. This protect mechanism should protect notebook from serious hardware damage.

When this happen after a while you should contact notebook to AC power supply and be able to start your notebook again.

My PC locks up / shuts down without any notice. It also takes a long time to start up. I believe the slow start up is because I have too much stuff opening up that is not really needed.

My PC is an XP Home, service pack 2.
My internet has been acting strangely lately. Sometimes it comes up with a white page or takes a couple of trys, also difficult to close at times.
These messages are now showing and the pages closes down even when I try to debug, also it closes down immediately at times when I click on something and sometimes I can't type on the search line.

dbgheap.c, line 1132, debug errorm debug assertion failed, breakpoint.

I have disabled 3rd party browser extensions, and have took off Google as my search engine.
I'm clean of malware or viruses.

Go easy on explaining to me, I'm a senior and a little slower then I'd like to be at times understanding.
Thank you.

Not sure if this is where I'm supposed to put this, but here goes. My father's laptop keeps shutting off. I know the battery is very poor, but I don't think it is what is causing the problem. When you boot the computer up, it runs through boot, loads windows, but as soon as it gets to the login screen, it suddenly does a hard shut down, like it suddenly loses power. Turn it back on and you get the "start windows normaly" option and it loads windows, but as soon as it comes to the login screen, complete shuts off, no shutting down, just hard shut down. The battery is bad enough that when you unplug the power cord, it shuts off like that, but the power cord was plugged in. We had a bad storm last night, but the power cord was plugged into a surge protector, so I don't know if the cord is damaged. When the computer shuts off at log in screen, it seems to do it at the same place. I don't know if it is a power issue or a Windows issue.

Any ideas? Thanks in advance guys

Recently while I was scanning for trojans, with TrojanHunter (and cleaning my temporary internet folder), Zone Alarm Pro decided to shut down. The program quickly asked me if I wanted True Vector back up but I am wondering if this perhaps was the reaction of a malicious program inside the PC or if sometimes it happens and I shouldn't be particularly worried...

Answer:Zone Alarm suddenly shuts down...

Sounds like a virus/worm of some sort. A lot of them do that these days. Try downloading : Stinger BUT before you run it, change the name of the executable. That could fool the worm enough to stop it from closing it.

In the last month my Satellite P20-S203 is not behaving so well, and unfortunately it seems the problem is a hardware one (but I'm not sure, and that's why Im writing here)

The computer just shuts down suddenly (it happened 2 or 3 times in the last 30 days); all the times it did happen I was on the web on Firefox, but I'm pretty sure it has nothing to do with that, and I'm also 99% sure it's not a virus, malware or anything like that, cause I formatted about 3 months ago, and nothing else behave in a strange way, the computer is not slow or anything like that.

The last two options are that the issue may be of hardware nature, or of a software one (like a conflict between installed programs and the OS); I'm more for the first one, but I'm not sure and I need help to find out... What should I do?

Also, when it suddenly shuts down, it won't turn on with the first try.
It needs like 10 or 20 times to open, like an old car that doesn't start; the first, say, 5 times I try to turn it on, it will only display the toshiba logo.
Then it passes through a screen I cannot read because it's too fast.

Then to a black screen and finally it turns off again.
With the next tries it goes a little bit more far, like it displays the windows logo, but, as that picture fades in, it stops at half of the fading process, resulting in a darker windows logo, like it's too hard for it to load the OS!!

But then it goes off again!

Then after some other tries it finally loa... Read more

Answer:Satellite P20-S203 shuts down suddenly


Possibly the notebook shuts down due to a higher internal temperature.
The high temperature can leads to a overheating issues and the notebook would shuts down automatically to prevent the hardware from damage.
The other point is that the high temperature can affect the RAM modules.
In such case the notebook can freezes or you would receive a Blue Screen Of Death.

I had a similar issue in the past. About 6 years ago my first oldie started to overheat.
I cleaned the cooling modules but the issues happened again.
Finally I contacted the notebook technician downtown and he said that the thermal grease which is placed between the cooling module and CPU must be renewed.

He did this and it helped!

It may well be overheating. At the very least, spray air into the vents to try and get dust out.
If he/she has the manual, you may want to attempt to take it apart and clean out some dust.

Answer:search function shuts down suddenly

Sounds like something could be corrupted. Just a guess though. When I have had funky problems, I have tried a couple of things, which include a repair/reinstall. Basically, you run your WinXP disc in a repair mode. It should replace only the Windows files, so your settings will remain the same. You will have to re-update your "updates" though.

Again, just a suggestion.

Starting today, my Satellite M70 suddenly shuts down while I'm working.
I've checked the forum here, and I guess it's a heating problem.
When I looked at the fan opening, I saw that the covering was broken...
And the fan itself doesn't seem to work either...
There must have been some kind of accident.
Does the regular warranty cover such things?
Thanks in advance!

Answer:Satellite M70 suddenly shuts down: fan problem?


I think you are right and the machine is overheating.
To get this repaired your only chance is a service partner of Toshiba.

Unfortunately this kind of damage must be the result of some kind of hit on the notebook.
And normally this is not covered by warranty.

My CPU has started to overheat. Does this come with age? The computer turns itself off, within as little as 30mins, even if it has not been used in a day.

SpeedFan says the CPU is 82oC

All the fans appear to be working. I have cleaned what i could and am waiting for a can of compressed air to arrive in the mail this week to get the dust out of the cracks.

Could the CPU need a new cooling agent?

How can i prevent the computer from shutting down? I work from home so this is my livlihood.

Answer:Computer suddenly overheating - shuts self down.

Cleaning the dust out will be the biggest issue.

Another thing you could do is re-apply thermal compound to the CPU, which will help the CPU transmit the heat from itself to the heatsink.

Hello im stuck in a very bad situation, i try to use my PC, but it only will remain on for about two minutes and then shuts off, then i try to turn it on again but it will remain on less and less time, until i just cant even get to windows. Then i let it rest for 10 or 20 minutes and then again the same situation ive described above.

I checked the PSU and it seems ok, i even changed it for a new one, but the situation is still the same.

I cant make a ram mem test because it shuts off first, dont have enough time.

I checked the temperatures at BIOS when i start the PC, this is the status right after i turn it on:

CPU Temp: 75 C, 167 F. (its a Pentium D)
MB Temp: 29 C, 84 F.
CPU Fan speed: 3276 rpm. (is this too slow????)
VCore Volt: 1.216 V.
3.3V Voltage: 3.32 V.
5V Voltage: 5.107 V.
12V Voltage: 12.032 V.
Q-Fan: Disabled.

And this are the readings just a minute or two later (without even going to Windows yet):

CPU Temp: 93 C, 199 F.
MB Temp: 38 C, 100 F.
CPU Fan speed: 3276 rpm.
VCore Volt: 1.216 V.
3.3V Voltage: 3.32 V.
5V Voltage: 5.107 V.
12V Voltage: 12.032 V.
Q-Fan: Disabled.

And then the PC just shuts off.

Are these temperatures very high? if so, what could be happening, i don`t have it overclocked or something, and in the room the temperature is not so high, it is hot, but acceptable, ive been in worst temperatures with no problem at all.

I hope someone can help me, thankx!!!

Just asking if anyone has any idea what's wrong with my notebook. I'm using satellite M200 + Vista home edition for like 6 months and there was no problem before.

My problem now is that my notebook will suddenly turn off without any warning or signs.
My notebook can only stay for approx 1 hour, I've checked the power option and there's nothing wrong with the setting.

So, if anyone has any idea maybe i can get some help.


Answer:Satellite M200 suddenly shuts down

It?s nothing wrong with your power, battery or whatever.
This issue looks more like a notebook overheating.

The notebook shuts down automatically to prevent the hardware from damage.
I think the notebook overheats because the ventilators don?t run with full performance due to the dust and debris inside the notebook.

What you could do is to clean the fans using the compressed air spray.
Such spray is an professional cleaning tool and you could buy it in most computer shops?

I have a Satellite 2180CDT that when it is in room temperature and you install a program, it suddenly shutdown and won?t start again until it has cooled down. It also happens that it hangs in the middle of an installation so you have to restart it and when this happens it is very hot on the bottom. You can almost fry an egg in your knee :-)

When I tried to install windows it hanged itself in the middle of the installation and I then needed to restart the installation many times. After several tries I tested to have the air-condition blow 4 degrees cold air on the computer and then the installation finally went good. If you have it on and it just stands, it happens that it shutdown then too, but it often hangs itself.

I never have had this faulty before we installed more RAM memory and I updated the BIOS, can this be the problem or is it just a coincidence that it happened after that?
What can I do or what should I do? The guarantee has expired and I don?t mind open it though it doesn?t do much good when I can?t use any program without it shutting itself off or hangs itself.

With kindly regards

Answer:Satellite 2180cdt suddenly shuts down

For me it?s clear case. All this sounds like an overheating.
This could happen if the notebook is a little bit older and the fans cannot work properly because of the dust and debris inside of unit.
You should check the cooling ventilators and try to clean it with the vacuum cleaner.
Furthermore it?s not advisable to use the notebook on the knees. All the ventilators grilles around and uner the notebook must be free.
It?s important for the fresh air circulation!!!

Please check this possibilities!
