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.best way to clean semi solid wooden floors Open the laptop case, so you can access the CPU fan and the heatsink. residential duct cleaning ctIn some cases you can access the heatsink through the latch on the bottom of the laptop. air duct cleaning services in ctSometimes you have to open the laptop case all the way down.best value canister vacuum cleaner

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.best canister vacuum cleaner 2015 UPDATE: I just received a nice tip from MC N’Colorado. cost of cleaning ac coilsI 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. 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.

You can support my work!A motherboard failure on a laptop that is out of warranty would usually mean that… it’s time for a new laptop. The price of a new motherboard is usually higher than the current value of the laptop. Plug in the power adaptor and try to start the laptop. Look for the “lid closed” switch and try pushing it a few times. It’s usually a small switch near the hinges that is pressed when the lid(the screen) is closed. Sometimes these switches get stuck in the “lid closed” position that results in black screen(no backlight) or non-starting laptop.

Also some laptops have a magnetic switch (newer Dell’s and most Apple’s), that doesn’t get stuck. Test the laptop with another power adaptor. Although not common, the adaptor can fail and not supply the needed voltage even if it has a green “power on” light that lights up when you plug it in. Even if you measure the output voltage and it’s OK, the adaptor may have failed and wouldn’t supply that voltage under load (typically 3.5A to 6A). You can use an universal adaptor or go to an independent repair shop and ask them to check it (some shops will try to charge you for “estimate” for doing just that, so ask in advance).See the article on RAM failures for instructions. Remove the hard drive and the CD/DVD if it’s easily removable. Finally try to start the laptop again with only the power adaptor plugged in and with the RAM reset and all removable components and the battery out. If there’s still nothing on the screen, you will need to bring it to a repair shop.
