I have a Satellite A75-S2292. It did the same thing to me. I just blow the vents & fans out weekly with canned air. I also have an under the laptop cooling fan, to increase the air flow. I haven't had it shut done for months, since I started doing some preventive maintenance.
The changing the thermal paste is not a good repair. Thermal paste will last for at least 20 years, under worse conditions than most computers will ever experience. Removing the processor chip, wiping everything clean & replacing the paste & chip just make more chances for damage.

Overheating and shutting down within several


The A-70 and A75 series both suffer from a very tight cooling system. If you are running a P4 its pretty marginal. Basically what you need to do is blow out and or clean the cooling system. On my A70 I had to do it every 4-6 months. Basically as soon as it started getting past warm on the bottom of the laptop it was time to blow it out.

Basically what happens is dust and oils (cooking oils, perfume oils etc) and hair collect on the cooler and reduce how effective it can cool.

So what you do to clean it is get a can of compressed air (keyboard blow off stuff) and two toothpick. Take the battery out and unplug it.Turn the laptop upside down. Insert the toothpick in the cooling fans. This is important as the air can turn the fans faster then they are meant to spin and could damage the fan bearings (new fan annoying and expensive -lots of labour). Take the compressed air and blow in from the exits and then blow in over the fans. What will surprise you is just how little dust will come out. It may just be one good puff of dust and thats it. When you do this a couple of times or don't see any more dust you are done. Take out the toothpicks and put the battery back in and turn it on. It should run much cooler.

Toshiba laptop will keep shuting off


It is because of the laptop overheating problem. This is a very common problem with and could be easily fixed if you clean the heat sink. 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 (for example Toshiba Satellite A70/A75) 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.

Toshiba Satellite A75-S231 overheating pls advise me


You need to open the Notebook and clean it with an Air-blower mainly near the CPU (Processor) area.

You need to check whether the CPU cooling fan is working properly or not, try cleaning it too, If the problem still persists replace the CPU cooling fan.

That's it.

Toshiba boots up power light stays on and shuts down, bad m/b ?


I own a Laptop Toshiba Satellite A75-S2131.
This series have a problem with the cooling flow to the processor.
The processor overheats and the laptop shuts down.To solve this particular problem you must tear down the laptop and clean up the processor heatsink (you will find it totally plugged or partially dirty).
Find in the internet the step by step instructions (with photos) for dismantling this laptop. Do not forget to apply thermal paste between processor & heatsink.

I hope this solution helps.

LCD lost the red color


First, plug a external monitor and toggle the screen with ALT+F4 to see if the image is correct there. This will discard software or configuration problems.
If the image in the external monitor is OK you problably have a hardware problem in the LCD panel or its cabling.
You can get the replacement parts here:

Unexpected shut down


First, you need to find out what is causing the shutdown problem.

Most likely since you have this laptop for 3years now and (i am assuming you havent had this serviced). You might be suffering from overheat problems since you are using a DESKTOP P4 cpu.

Try to dismantle your laptop and remove the Fan and Heat sink. CLEAN them and put new thermal paste to the cpu.

Do that and see if this fixes the problem. If not, let me know again

If i was able to help please rate this solution as a fixya!

thanks
