Hey. I'm running XP Pro on a satellite 1905-s301. Got a P4 2.0 ghz, 512 mb memory.. My problem is that my laptop will completely shutdown, not windows goodbye screen or logoff but exactly like if I just held down the power button to shutdown, during "processor intensive" applications. The two that seem to be the most demanding, as far as shutdown percentage (100%), are EA's NHL 2004 and the Stinger virus checker program available from McAfee. I have ran both of these programs successfully prior to now. My laptop has always had a problem of randomly restarting (which I never got looked at...shame on me... but believe to be a hardware issue from when I had the extra 256mb of ram put in when i bought the computer?), but have never a complete black screen shutdown issue. I don't have any viruses, and eliminate spyware as it comes, I run a firewall, etc... I am wondering if anyone can suggest a possible problem that this might be so that I can avoid taking it in to the shop. The NHL game does not crash during the menus, only during actual gameplay (I tried lowering frame rates and details, no dice). The stinger program crashes usually about 4 or 5 minutes in to scanning my hard drive. Any possible leads would be appreciated...Thanks.

Hey there,
I was wondering if you had found a solution to this problem. I'm having the same problem. It helps to check to make sure that your set in Max performance mode in the power utility so it will spin up the fan more, and make sure your fan is not blocked, but even with this, I'm getting crashes. Crashes mostly occur on my computer when I'm playing games, so I'm temped to assume that it's a graphics card overheating issue in my case. Let me know if you've found anything else.

I am having the same problem with a client's machine. Its a Satellite 1900-824 and it started just shutting down, no warning what so ever, about 2 weeks after adding a new stick of RAM (256MB). Talked with the store tech that we got it from and they mentioned about the blocked fan and to get more air flow but no go. I am going to look at the power settings as mentioned in this thread and see if that helps any. Games aren't running on this machine so I am fairly confident that it is not a vid card issue, but could be mistaken. If you hear of anything please let me know as well. Thanks.

I am also having this problem on my 1955-S803. The laptop works fine when surfing the web or working with apps that don't require a lot of processing power. However, when I play games or work with photo editing software such as Photoshop the computer will ALWAYS shut down after 5-10 minutes. I've had the computer now for about 1 1/2 years and it didn't do this when I first got it. I can find nothing on Toshiba's website about this, which is odd considering that it seems that lots of people are having this issue.

I have a Toshiba Satellite 1905 - S303. I'm having similar problems. All my virus checkers are up to date, and the cooling fan is clear and has no obstructions. This is what is happening. Sometimes the computer just randomly shuts off. Even when the computer has not overheated. It does this even when the comp. is cold to the touch.

It usually happens when I am using a graphics program. Here is what I have noticed. I have been using programs to encode video files into the right format so that I can burn them on to a Video CD. Everytime I started the video encoding program, the computer shuts off after a couple of minutes. Whne I have the task manager open, this is what I noticed. When i start endcoding video, the CPU usage immediately jumps up to 99% and stays in the 90's. When the computer is at sustained at this level of CPU usage it automatically shuts off. Its even done this on very cold starts. It shuts off right when the CPU jumps to this level of usage. It doesn't do this just for the graphics programs but for any program that uses 99% CPU usage for a long period of time.

Is this even an overheat issue? Does anyone know how to correct this.

I even tried updating the BIOS, but right in the middle of updating BIOS, the damn computer shut off. I don't want to attempt that again since I have a lot of my files on the computer, and I don't want anything to get lost.

has anyone else been experiencing this problem, and more importantly, has anyone found any solutions?

MY Satellite is having the same problem. No viruses, no spyware, running a firewall and the machine works fine except the shut down issue. Mine will shut down just using the IE and Outlook. It doesn't seem to be application or length of time on that is causing it.

I've done a thourough cleaning of my computer. I went out and bought a T6 Torx bit, removed the heatsink from the processor and cleaned the fan and heatsink with a compressed air can. It's unbelievable the stuff that was built up inside. The dust bunnies were the size of buffalos! I then reapplied some thermal compound and reattached the heatsink to the processor. The computer has run like a dream ever since. I can even play intensive games for hours on end without a crash. The fan runs much less often than before the cleaning as well.

If you're not an experienced technician, DO NOT attempt this yourself. Bring it in the have it cleaned. If you do do it yourself, be careful when you're removing the is glued to the processor. Don't yank out the processor and bend the pins.

Hi everyone,

Letme solve ur problems. I have a toshiba satellite 5200-902, for the ones who dont know it, its a 2.4Ghz 512MB ram, 80Gb Hdd, and Gforce FX 5600 128 MB ram version. My laptop is liquid cooled as its original setup and I had the same problem but i solved it today. Simply even if you think ur fan system is not clogged or restricted, its the things that u dont see from outside is important. I took apart all the parts and opened up my laptop to reveal everything inside it. The cooling system consist of a small radiator (like a cars radiator, one in the front for cooling) and attached to it is a small length cupper tube with a special coolant in it, and the other side it pressed to a magnesium piece which sits on the CPU. and the fan is between the ends of this cooling system, taking the inner air, blowing it through the radiator to outside. Believe it or not, even my laptop is only 6-7 months old, the blocked radiator had about 3-4mm of dust accumulated on its blow-way, which in time became harder, like a shell. So cut to the chase: the difference now is you can really feel the fan blowing air hard from the back side and laptop came to its original speed. (More heat in the cpu and mainboard area, the slower the machine gets). So do ur self a favor, either take it to service to clean it up, or wash ur hands, ground urself and start the surgery.

I think I can add some useful information to this discussion. I too have had periodic spontaneous shutoffs with my Toshiba laptop, a Satellite 1905-S301. However, I run Linux as my primary operating system. This should eliminate buggy drivers as the reasons for the shutdowns. That said, the shutdowns are FAR more frequent when I am in Windows XP Home than in my Gentoo Linux install.

Just for reference, I have only had it shut down on me twice EVER in Linux, but its already happened twice JUST TODAY in Windows XP Home. It occured while I was simultaneously running bittorrent, watching a Divx AVI, and using Putty SCP to transfer the same AVI to another machine. The CPU was maxed.

I regularly max the CPU in Linux while I rip CDs to MP3, so I don't think this is the culprit. I have noticed that my laptop's performance in Windows is quite poor, which seems to be the result of incredibly crappy IDE drivers. Even moderate hard drive access destroys Windows' performance. This problem is not pronounced in Linux, leading me to believe drivers are at fault. In both cases my laptop restarted today, it was during both heavy CPU usage and disk access while in Windows. Again, this almost never happens in Linux, so I have to assume it's some sort of problem with Windows/drivers, in combination with excessive heat or something.

The problem is not windows or linux-centric, I have a friends 1955-s801 that shuts down in windows, booting from a knoppix cd, and booting via pxe over the network from a knoppix-terminalserver. Will try to find that t6 torx...

>> Re: Toshiba Satellite Shutdown
Can anyone post where they found that t6 TORX? It sounds like cleaning the beast out is the only solution. I have been living with this for over a year. Started happening just after warranty expired. Just so that you all know.. the problem gets progressively worse. Now the computer won't stay one any longer than fifteen to thirty mintues under its own steam. I say that bc. I have a large fan blowing night and day behind the propped up laptop to keep it running. Even with that, I can not play a video game, a long movie, or good forbid.. multitask. I hope I haven't already damaged the M/B or CPU with all the heat. Does any one know if we can possibly plug in a newer or cooler chip? What about yanking out the whole M/B and replacing it with a new M/B and CPU/GPU compination that fits, and then hook everything else back up... Any chance this might work?

Thanks in advance,

The solution that seemded to work for me was cleaning out the CPU fan and case fans inside the laptop. Since I did that it seems to be working good so far. Hopefully with your warranty you can get something done about this. Good luck!

Hey guys wassup, i also have a satellite 1900 (its freaken high maintainance laptop ) lol , but yea i remember before when i first bought it , i would play medal of honor for hours i could model in 3dstudio max for nights and it would be fine, then after time it just crapeed out on me, started overheating that is just how laptops are ive seen the same with alot of other laptops. ... well recently i went out and i bought an antec notebook cooling and i suggest you do the same

its like a stand with fans underneather. really cool looking , but it works pretty well so far, i went into 3d studio max and opend up one of my biggest work file and i rendered thes**t out of it at max. and it rendered the image in 10 minutes of intense proccessing, ( as to before i would get 1 min into the render and it would just shut down )

by the way, can someone help me out, i got a pcmcia dlink card, and everytime it plug it itnto the slot, it would not boot into windows it would freeze in the windows logo, but when i will boot into windows without it, it works! WTF?
i thought it was windows, so i reinstalled it, and windows xp would not reinstall with the dlink card, it would just freek.

>> Cleaned out heat sink
I took the advise of the posters above and removed my heat sink and cleaned it out. I have a s801-1955 Pentium 4 2.2mhz. So far, my computer seems to be working fine without my huge room fan and Coolmaster laptop cooling unit. I am going to push all day to see if I can make it shut down. I did learn some lessons that I feel I should pass on:

1) My original intent was to open up the entire laptop case and clean everything inside. This proved to be a waste of time. I removed about twenty screws and the case is still locked. I prodded and pulled, but I was worried about breaking it, so I stopped.

2) All you really need to do for the heat sink operation is remove the two torax screws on the panel covering the heatsink. I could find this screw driver so I used a large drill bit and bored out the screws. I could glue it back now, but I think I want to leave it open. This seems to be the only implementation of these funny screws that I can see in the laptop, which is really annoying because this should be a common maintenance routine that users should do monthly.

3) Next, carefully peel away the chrome metal covering, it is only glued on. (this is another thing that I plan to leave off to improve circulation). You will then see the heat sink pinned down by two wing brackets. TIP: Only unscrew the corner screws, I found out the hard way that the inside for screws just attach the wing brackets to the heatsink. If you remove just the four corner screws, you can pull out the heatsink using a firm and steady yank directly upwards.

4) Clean it out.. I used a powerful fan. If you got a compressor cool, whatever you have should work. You can see by holding it up if it is clean. I also cleaned out the inside a bit with a diaper wipee and I cleaned the external fan mesh which was also blocked.

5) Simply reverse the process.

I also noticed that the CPU looked easily upgradable, with a single lever to remove. So now I am price shopping for Pentium 2.6mhz chips which seems to be the fastest available for this M/B.

Cheers, please post if you try it and it works for you.

I have a satellite 1905-s301
Well, I cleaned out the huge amount of dust from the heatsink through the slots on the side without using a t6 screwdriver. Before cleaning and continuously after, the fan started making awful loud noises that grew progressively worse. I COMPLETELY dismanteled the laptop to try and fix this fan. THIS IS NOT ADVISED! Whoever layed out this laptop setup had to be a masichist (spelling?) I finally got to the fan and found that the blades were hitting the bottom of the casing (how the fan became dislodged - I have no clue). I had to super-glue the top of the fan to the top of the casing. Fan works fine now - BUT - now that I put the case and everything back together, the computer shuts off when I try to use some programs. Sometimes it shuts off when I enter win xp through one of my logon names! Yes, the fan works fine and runs like normal. It used to shup off every once and awhile when I was playing a processor-intensive game with the laptop on my lap, but now, it is intolerable.
Researching this online, I'm thinking i need to put some type of thermal material between the heatsink and the processor. Thermal grease maybe? I'm thinking maybe I bent the heatsink when removing it and air is getting trapped. I will try the thermal grease tomorrow and let you know.

Notes when dismantiling this laptop:
I believe I got the t6 torque screwdriver from Home Depot (Lowes and radio shack didn't have it).
The casing will crack if you open it completely.
There is no way to keep the different screws straight.
Important - always remember to take off the little power board (where you press the button to power it up) before you open it up. I actually broke this and had to get a $40 replacement.
Important - detatch the power cord and remove the battery everytime you tinker with the insides.

The Artic Silver thermal grease stuff seems to work. I had to apply it twice. The small amount suggested for use (the size of a grain of sand) wasn't enough. I had to put about the size of an orange seed on the interface between the metal cover on the processor and the heatsink. It hasn't shut down yet. Finally, I think I've found my solution! Yay

THANK YOU, THANK YOU for sharing the solution to this infuriating problem!

I was having the same problems with intermittent sudden shutdown of my Toshiba Satellite 1905-s301. I somehow got the erroneous impression that the problem was occurring during periods of high disk activity (which probably does correlate with processor-intensive functions). It had all the hallmarks of a hardware issue, so I assumed my hard drive was in its death throes. Boy, did I feel feel foolish after plopping down $125 for a replacement drive only to have the problem continue as before. I stumbled onto this thread during a desperate Google search for the problem, and I think I literally whacked my forehead when I read about the overheating proc.

I couldn't even wait to get the proper screwdriver to remove the access panel. Instead I gouged the plastic around the screwheads until I could fit in a tweezer and use it to turn the screws. Opening the panel exposed the heatsink, which is held in place by four corner screws. As mentioned elsewhere here, only the corner screws actually fasten the heatsink to the motherboard.The heatsink lifted out with a little coaxing (it's a close fit inside the access panel). It was indeed caked with dust on the edge proximal to the fan.

I removed the dust by blowing it out with compressed air, then I rinsed off remaining residue with 90% isopropyl alcohol. I used the same 90% isopropyl alcohol on a lint-free microfiber lens cleaning cloth to wipe away the old thermal grease from the heatsink and the proc. I also removed as much dust as I could from all accessible surfaces within the access panel (especially around the fan area). I then applied Arctic Silver 3 thermal compound to the processor, carefully spreading it thinly and evenly with a razor. I reinstalled the heatsink (taking care to ensure that it was oriented in the same position as before) and fastened the screws tightly (the correct order for replacing the screws is embossed on the superior surface of the heatsink assembly).

The entire procedure took about 1.5 hours, and most of that time was spent trying to get the screws off the access panel without the proper screwdriver. I did not replace those screws; instead I taped the access door back on. My laptop has operated flawlessly since. I have repeatedly performed several different tasks that previously always precipitated a shutdown (such as running a full antivirus scan or running a spyware scan), and these tasks now finish uneventfully every time. I also notice that now the fan does not spin up nearly as frequently (nor to the same high rate of speed) as it used to. In other words, my laptop fan is now as consistently quiet as when the laptop was brand new.

It took almost 2 years for my laptop to develop this problem from the day I bought it. In retrospect, it started showing minor signs that it was running hotter as soon as 1 year after it was purchased (signs such as fan spinning up more frequently, and spinning more loudly, as well as noticeable heat emerging from vent next to proc).

I doubt that it is possible to completely prevent this problem from emerging over time, but I'm taking what preventive action I can to forestall a reoccurence. I have taped a filter screen over the fan opening on the bottom of the laptop to reduce the amount of dust being drawn in by the fan. I have also fastened adhesive rubber feet to the bottom of the laptop (I stuck them right on the existing rubber feet) to provide greater clearance under the unit for better airflow. This was a cheaper solution than purchasing one of the available specialized devices that do essentially the same thing (I saw one with a fan of its own to blow air on the underside of the laptop), but anyone who frequently transports their laptop will probably want to use the specialized device rather than my low-tech improvisation. The adhesive rubber feet do come off easily if you move the laptop much.

So, in retrospect, it's very obvious that this is problem is thermal in origin. One clear indicator of this was that if I turned my laptop right back on immediately after a shutdown, it would start to boot and then quickly shut off again. If I waited before turning it back on after a shutdown, it would boot up normally. In other words, it needed a cool-down period after a sudden shutdown. And of course, the observations that (1) there was indeed a layer of dust impeding airflow around the heatsink, and (2) the problem completely abated after the dust was removed seem to confirm the hypothesis that this sudden shutdown problem is caused by overheating of the processor due to dust buildup impeding airflow through the heatsink fins. It's obvious in retrospect, but if I hadn't found this thread, I would never have thought of it and I would have wasted untold time and money having the problem diagnosed at a Toshiba service center.

Dear Fellow-Victims-of-Toshiba-Shoddiness. (Isn't it amazing how Toshiba can stay in business!? ) We are all using our LAST ever Toshiba, I presume!!

This is my experience and finding with a 1955-S801's shutdown problem. The problem is with the cooling fan.

There are 2 ways to test this theory.
1) If you turn on your laptop and do not hear a fan sound for about a second or two, the fan is most likely NOT working. Depending on the temperature of the place you're in, your computer should shut down in a matter of minutes even if you're not running any programs. 2) Place a fan directly over the vent opening and see if that would prolong the operation of the machine. You can use a computer fan, a hair-blower SET ON COOL, or even a vacuum cleaner.

My experience is that the fan was binding/stuck (on the casing?). What you can try WITHOUT opening up everything is to put a vacuum hose to the fan opening and see if the fan can spin free again. (This should also suck up any accuminated dust.) If this should fail to solve your problem, you have 3 possible solutions. 1) Send it in to have the fan replaced. 2) Or open it up yourself and try to free the fan up. 3) hook up a small computer fan and velcro it to the computer. (Unfortunately, MOST computer fans run on 12 VDC.).

I only know of one place where you can purchase a replacement fan for the 1955-S801.

God Bless,

It was working fine for two weeks and now I have the same problem. I shuts down every 30 min.
I donot think the dust has anything to do with this problem. Its been two weeks only since I bought the system. So, I don't think the dust is accumalated so quickly.

Any other thoughts which might be doing this...Thanx in advance.
