Question about Toshiba Satellite 1805-S274 Notebook
Yes I had exactly the same problem. The fan bearings had worn out. So when the CPU reached the preset BIOS temperature, it actually rebooted rather than shutdown. Anyway, here's the good bit - I found a little PC repair shop and they sold me a fan for one euro.

Try this - (my daughter's computer wouldn't either - the socket is slightly faulty) - rest a reasonably heavy item on top of the plug that plugs into the computer socket - our's then charged - my daughter now uses this constantly (not ideal I know) until such time that we can see to fixing the socket. Good luck!

A couple of additional thoughts. First, your video chip may be what is heating up, as opposed to the processor. And as sandrew said, a pc repair shop is the way to go. Secondly, malware can cause this. If you have AdAware, or similar installed, try to update the definitions and run that.

My laptop has the same problem. I found that everytime my laptop freezes I just dis-connect the battery and run it on the adapter. it solves the problem. hope it works for you.

I have a toshiba laptop which was unexpectedly switching off. The laptop was 2 years old. I did lots of searching online to discover this is a VERY COMMON ISSUE. The problem is, dust blocks the heatsink. When I took my computer to pieces, I found a strip of dust half an inch (1cm) thick covering the back of the heatsink which prevented air flow. If your laptop is a couple of years old, this could be the problem. When I removed this dust, the problem disappeared. If you are computer savvy, then try the following - if not, take it down to a computer shop! 1) Remove the 5 screws holding down the heat sink cover and processor cover. These are on the bottom of the laptop, in the centre, at the back. 2) Remove the 3 screws which hold in the heat sink in place. 3) Remove the heatsink 4) Take the dust out 5) Re-assemble a note: be careful not to get dust in the thermal paste on the cpu - unless you have replacement paste. Good Luck!

You have to remove the processor heat sink/fan assembly and then unscrew and remove the fan. Look inside and you will find a wad of lint at the entrance to the heatsink fins. Clean the lint out of the heatsink. The laptop now has cooling.

I had the same problem with mine and under warranty it needed a new motherboard battery and ac adaptor, same thing is happening again now, and its out of warranty, not worth getting repaired.

How about replacing the processor?

I have this computer, and a similar problem. A $30 cooling pad with 2 fans in it has solved the problem, for the most part. The fans aren't really usually the highest quality - the cords on them are delicate, and I can see needing to replace the pad at least once a year as a result - but they *are* cheaper than a new laptop. Since I got the cooling pad a year ago, I have had no overheat/shutdown problems.

It once helped me to shut the computer down, take the battery out and then place it back in again. Give it a shot.

You don't have to spend your money on a pc repair shop. just open your laptop and clean the fan. i did that and removed bricks of dust! now it's quiet and cool again

Make sure you can hear your fan on boot up as it should start immediately, if not cooling problem down to fan, if it does check that the vents on side and underneath are'nt blocked with dust, hoover with attachment gently. if still persists, as long as you have'nt tried to speed up processor in settings, then your processor is overheating causing shutdown, and a pc repair shop is only answer, although probably cheaper purchasing a more new upto date laptop.
