Most likely...computers are designed to shutdown if the processor gets too hot to prevent damage to the processor and/or motherboard.

Thanks and please take a moment to rate as fixya. Thank you.

Tecra-A2 goes into critical shutdown.What can I do?


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

Unexpected shut down of my laptop


It is quite possible that the laptop is overheating and the processor has a thermal shutdown circuit. Take a can of compressed air from an office supply store and blow the dust and hair out of the ventilation grills on the laptop. Once you do this, reboot the laptop and make sure the laptop fan is running. If a system has been run hot for a period of time, it is also possible that the thermal paste on the processor has dried up and has "caked" on the processor/heatsink lowering the efficiency of the cooling properties. In that case, the heatsink would need to be removed and a new layer of thermal paste applied.

My Toshiba P35-S611 shuts down without warning a short time (2 min-45 min) after it boots up. The battery isn't hot but the heat dissipation fins in the back are very hot.


Indications of laptop overheating problem:
  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 (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.

Abrupt shutdowns


Is it very hot?

If so Tkae compressed air and blow it into all the vents on the computer. You are trying to loosen dust. Get it all loose possible near the vents then **** out all dust you cna with a vacuum cleaner.

This should stop the laptop from overheating and shutting down.

My Tecra Toshiba will not turn on or off, even plugged in.


Yes it is. And, it is highly recommended that you remove the battery if you're going to use your laptop for more than 1 hour. If you keep your battery in and have the laptop connected to the adapter, the poor battery is going to be charging/discharging so much that its life is greatly shortened. Also, this is what causes dead cells in batteries.
You might possibly have an internal power supply problem.
But, go ahead - remove the battery. See if it helps.
You also might try letting the battery charge for 3 hours with the laptop off.

My Toshiba laptop TECRA A9 shuts down on second attempt only, not the first time. What can I do?


Hi..

Laptop shuts down? Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage. If the smart person keeps turning the notebook back on and figures out a way to foil the protection, the laptop is probably doomed. Once a laptop shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot. The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated laptop is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down. Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning. Hot spot, fan always runs? Many laptop brands and models have characteristic hot spots, like a particular corner of the keyboard or over the battery compartment. Before proceeding with the more invasive cleaning techniques that involve opening up the laptop (and potentially breaking something), spend some time searching the web for user feedback on your make and model. The bothersome hot spot on your laptop that none of your friends or colleagues have ever hear of may be a characteristic issue with your particular model and not worth a major panic.Similarly, if the fan always runs, or almost always runs, it may be a characteristic of the particular model that it simply gets hot in normal operation, or the fan control software might be poorly conceived. As long as the laptop isn’t overheating, I’d probably learn to live with a fan that seems to run too much if it’s typical for the model, and only get worried when I don’t hear it anymore.

Laptop turning off


Often, if a system turns off every time at roughly the same time, it's a hardware problem. System gets too hot, shuts down, restart it and it'll run again for a while, but not quite as long, and continue like that. Can you feel/hear the fan moving air? Possibly clogged, see what you can do to get it cleaned up a bit. Does it make any difference what surface it's on? May be covering a vent on the bottom or back.
