Why my Toshiba laptop suddenly shuts down by itself without warning?
“My Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint we hear from our customers over and over again. About 15-20% of all Toshiba laptops we get for repair, suffer from an overheating problem. Yep, OVERHEATING!
This is one of the most common problems with Toshiba laptops we deal with.
Indications of laptop overheating problem:
- The keyboard and the bottom of your laptop are very hot when the laptop is working.
- The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
- The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
- The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).
If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
- Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the laptop case all the way down.
- Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
- Clean the fan and the heatsink with compressed air.
- I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.
UPDATE: I just received a nice tip from MC N’Colorado. I think it could be useful for all of you with guys:
I decided to use a shop vac to suck the dust out and it worked. I tested it by letting the machine run all night and it worked. It’s been a couple of weeks now and I’m glad I did it. I was ready to take the machine apart, now I’m glad I didn’t. I’d suggest you use a heavy duty shop vac to clean out the fan and heat sinks first.
I agree. Try to fix the problem without taking the laptop apart first but I would recommend using a powerful air compressor instead of a vacuum cleaner.
If your laptop is still under warranty, you can take it to any Toshiba Authorize Service Provider and fix the problem at no charge to you.

I don’t know if this will reach anyone. I find it difficult to understand how the forums work. If this reaches someone who could help, I’d be most grateful. I have a Toshiba Satellite P30 2yrs. old. My most recent problem - I wear wrist braces for my arthritis and hit a key accidentally and the text and icons increased in size and distortion. I can see them better but need it back the way it was. I cannot edit photos that are distorted.
All text size settings are unchanged. I know the problem is the Toshiba Zooming Utility Fn+1 which should reduce it, but it does not work!!!! All the other Toshiba “hot keys” work except Fn+1 and Fn+2 (I guess that one worked well because it is the enlarge function which I probably hit with my wrist and it worked just fine but Fn+1 won’t).
Toshiba won’t tell me how to fix unless I pay them $40 which I don’t have.
Can anyone help me or direct me to a site where the information might be? Thank you.

Hi, I have a Satellite A105-S2712 with the following problem.
After about 20 minutes of use the screen flashes. It can go on for about 2 hours of intermittent flashing but with no apparent pattern. At some stage the screen will black out with only a few horizontal grey lines at about a third way down the screen.
If the computer is running on battery power than the screen goes white and flashes with the horizontal lines barely visible.
None of this happens on an external screen.
Otherwise the computer continues to function and can be switched off by pressing the on/off button.
I have opened the computer and cleaned the heat sink and reapplied grease to the processor but it makes no difference. The computer is almost 2 years old and was getting very hot for some time with no adverse effects. Although it doesn’t get as hot since it’s been cleaned I wonder if the overheating in the past has caused irrepareable damage.
Enquiries on other forums suggest the inverter may be to blame or the screen or even the motherboard.
Any help would be appreciated and thanks in advance.

We too have a toshiba satelite laptop that shuts off after a few minutes of operation, we bought a 4 inch fan and have it blowing under the laptop while its on, and it stays running fine, apparently these laptops dont have proper ventilation, I think we need to start a class action lawsuit against Toshiba to force them to buy back the defective laptop computers that can IN court be proven to overheat due to a design flaw, any takers on attorneys that will take this issue to court?

Regarding Toshiba extending the warranty on the Satellite A75…just another loophole for a huge “don’t give a crap about consumers” company. I found their customer relations department arrogant and indifferent. I’ve had nothing but problems with my laptop since purchasing it new. Toshiba never contacted me about the extended warranty. I stumbled across the info while online one day. I sent the unit in before the deadline and they said they would have to charge me $400 to repair the overheating problem!….because I had modified the power supply. And you know what???? I’ve NEVER had a power supply issue since me and a teenage neighbor replaced the faulty Toshiba design. Enough said. I’ll never purchase any Toshiba product again.

Panelle,
At this point it’s hard to tell what is wrong. You’ll have to test the laptop with an external monitor and find out if the laptop works with an external monitor and external video is fine.

Using an air compressor or compressed air is not actually the best way to do this. A vacuum is. The reason is simple, a vacuum pulls the dirt, dust, debris out the same way it came in, but a compressor can actually force the stuff in tighter. If you have just a dust problem for sure then you can use air, but if you have pets or hair you need o watch when you blow it out. Make sure the fans are stopped and cannot spin up or you will eventually burn out bearings as the air will severly overspeed them. Put the air in and you should get a few good puffs of dust. If you don’t get much dust then you probably have hair or lint clogging the vents and the things needs to come apart to get it clean.

I don’t have a compressed air can in my home, but as someone suggested I used my vacuum cleaner. It seems to have worked well. My fan turns on now!
Hopefully it won’t heat up and shut down as much. thanks!!!!!

I discovered my cat has been using my lap top as a spare litter box. Apparently cat feces not beficial to the Dell circuitry.
