Toshiba suddenly shuts down by itself posted in: Overheating, Toshiba Problems | “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. 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 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.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.removing dust from laptop fan 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.price of vacuum cleaner in nepal Toshiba Satellite A15 Clogged Heatsinklaptop cooling fan not spinning

this Toshiba A65, all it takes is some careful prying and two screws. always, remove the battery before working on any laptop. The first step is removing the combination blank and hinge cover that allows access to the two screws securing the keyboard. It is snapped into place with little tabs on the long edge and a big tab on each end. The picture to the right shows how the blank and the hinge cover are all one piece of plastic, so you have to open the screen to fully remove theI should mention for desperate people with no mechanical skills, one non-invasive way to extend the length of time a notebook with poor cooling will run between shutdowns is to run it on battery and choose the most aggressive (ie, longest life) power saving mode. BTW, I'm working on this notebook because I was asked to bypass the power connector as a favor. got five kids in the house and I burned my finger on the metal part of the 100BaseT port after I got it charging again, so I'm afraid to return it for

The problem I was originally asked to fix should have tipped me off to the overheating issues this notebook would suffer. The pin had broken out of the center of the power connector on the motherboard, which meant the batteryMy fix (really a kludge) was to solder a new wire directly to the connector and bring it out the I/O port blank on the back of the notebook. The coax power cable was HUGE. Turned out to be rated for 2.0 amps. secure the keyboard in the laptop, and it's not even necessary to disconnect the ribbon connector from the motherboard to access the fans. laptop uses two fans, a large exhaust fan that pulls cooling air through the body of the notebook, and a smaller CPU fan on top of the large heatsink. The large fan to the right draws cooling air in the bottom of the laptop, the smaller fan in the center is directly cooling the CPU. overheating is pretty much limited to making sure the laptop fans operate and aren't completely burried in lint.

This is a pretty robust cooling system and likely to keep most laptops from shutting down from thermal overload protection, but they stuck a P4 2.8 Ghz CPU in this puppy! When I went out on the web and read some reviews of how this laptop performed when new, I saw comments like "Keyboard gets too hot to type" and "Frequent shutdownsSony made a Vaio with the same CPU, HP made an Pavilion and Dell an Inspiron. I've seen similar overheating and battery life complaints for them as well. As you can see to the left, there was a build-up of dust on the CPU fan which I blew out with compressed air, but not enough to cause any thermal shutdownThe reason I burned my finger on this boat anchor is it just runs too hot as a design flaw. OK, I didn't get a blister, but I'm afraid to put this laptop with a kludged power connector in a family home. know how they could have forced more air through this thing than with the big intake fan they are already using, so troubleshooting includes making
