How do you stop a laptop from shutting down?


When the overheating issue is fixed, the laptop will reset. Did you clean the radiator? Is the fan running?

Eee 1015PE is overheating and shutting down


Is the fan working? You will need to replace your fan if it's not functioning. And don't use it in that condition, you risk damaging it everytime it overheats

Not booting, no power, overheating


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.

My computer shut off by itself even though the battery was charged and the battery light kept blinking even after my computer was off. computer seems hotter than usual on bottom as well


It is probably shutting down to prevent thermal damage dut to overheating. Check that the fan is working. Even if it is, if the vents are clogged with dust the machine will not be able to cool properly. The only real remedy is to open the case, clean all the vents and fan, remove the heatsink, clean off old thermal paste and apply new paste before replacing the heatsink and putting back together.

Computer shuts off at random


It sounds like it's overheating, check your fans make sure all are working, if your fans are all working then your power supply is overheating and should be replaced. If your system is a laptop the battery can overheat also and shut the system down. So you can have different issues dependent on laptop to desktop.

Shuts down not allowing Windows XP to start


If the Computer shuts down automatically, then the issue might usually be due to the overheating issues.
The overheating issues develop, if the Cooling Fan in the Computer is malfunctioning.
The Processors are designed to shut down automatically, if there are any overheating issues.
For such issues, it would be better to get the Unit examined at the Service Center.
Replacing the Cooling Fan should resolve the issue.

Hope this helps.

Is overheating and shutting down, also the keyboard keys are sticking, sometimes I have to strike the same key twice


If the computer is restarting then it might be the FAN issue and FAN need to be replaced, but if the computer is shutting down then go to dell website, then go to driver downloads and update the BIOS then check weather issue perists..


Hope it will work!!!

Hp paviolon dv2000 shuts down by itself


Hi.
If computer turns off when idle, then check power saving settings, accessible from control panel.
If laptop turns off while you are using it, try first reinstalling the system to exclude system problems, or test the laptop starting OS from CD or staying in Bios settings mode, so to exclude installed system.
If laptop is still shutting down, then problem may be overheating.
Overheating usually happens when the fan is not coming , therefore when the computer overheats.Or the fan is not cooling enough and computer is overheating.

Monitor computer temperature using a software, check if Fan is coming up when temperature gets critical.

If fan comes up but does not cool enough, then replace the fan, it is not efficient anymore because of a bad bearing or dust. ~Also ensure that fan is well mounted, if fan has poor contact with CPU surface , cooling will be poor.

If fan does not come up, and critical temp is not detected, then the sensor on motherboard is bad, this is very uncommon. When this happens the problem is usually related to system or power settiings , rather than overheating.

If fan does not come up and temp is critical, then fan is faulty, replace it.

There are also more than one fan on many laptops, check that one of the fans (CPU fan, video fan) is not completely ded, and therefore cause for the problem.

By using the software below you can also find out if the problem is really overheating. If temperature results within normal range, then usually it is not overheating.In that case test systtem and check power saving settings.

Here is the software to control your fan and temp. sensor state:

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.

Keeps Shutting Down


First, start by taking the fan and heat sink out and cleaning them. Dust build up can cause overheating. Also check the fan for hairs or carpet fibers that have gotten wound in it, I've had fans stop working due to this. Then put it back together and check to see if the fan is coming on and running in regular intervals. If it's not it will need replaced. If it is, then there may be a malfunction with the processor or a short on the motherboard.
