Heating After 10 minutes working on my laptop comes hot in the upper side of the panel and some times shut down suddenly.I must wait almost 10or15 minutes before re-start my machine

sounds like there could be a problem somewhere along the fuel line either between the pump and that engine or between the filter and the engine i have a car that would do the same thing turned out to be the fuel filter was full of **** ran like a dream after i changed that.

1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
3. 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.
4. 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.).

Solution:
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.

1. 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 you have to open the laptop case all the way down.
2. 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.
3. Clean the fan and the heatsink with compressed air.
4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

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.

“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.

Hi
try this,
unplug dc plug from laptop. remove battery.
wait a few minutes. press and hold the power button for 10-15 seconds.
plug the dc power plug back into the laptop, but do not put battery back in yet. Then try to power on. if it powers on, let it run a few minutes, but best to keep checking to see if it is getting warm or hot anywhere. if it is getting hot shut it down immediately. If it isnt getting hot then shut it down and put the battery back in.

if it doesnt power up, then i would have to suspect heat damage to the motherboard.

Sounds like it is getting too hot and the hi-temp safety switch opens up until it cools down again. Try vacuuming all of the vent pipes and hose. Remove the lint screen and wash it in hot water and detergent to clean it of fabric softener deposits. Hope this helps!

Your gas valve coils are defective. Part #694539 and 694540 are required. Once the coils get hot they collapse internally and the gas valve shuts off. This is a common problem when valve coils get weak from use.

You need to clean it out with some compressed air.

Make sure the laptop is turned off of course.

If you still have heating issues, then you'll need to take it apart and put a new layer of thermal paste on the heat sink / cpu.

Best of luck!

they are equiped with a heat sensor it could be a bad thermastat(sensor) or
ventalation problem
