Hoover the vents - they're probably full of dust.

Try working on your laptop when you are in a much cooler environment than the usual. the possible reason for your laptop shutting down could be either the processor is getting to hot due to which the cooling unit of the system i not able to cool it down & keep the system temperature under control. I would also like to know the model of the system that you are using at the same time would also like to know the approximate age of the computer that you have been using. I possible which brand is your system & whats the Os its running on... thanks & regards

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

hope this helps

Turns itself off & gets hot -don't think fan is kicking on


Since you do not hear the fan anymore I would start by opening up the case and seeing if power is going to the fan and make sure any connectors for it have not come loose. If the connectors are still hooked up chances are the fan is shot and needs to be replaced.

If you are not familiar with working around electronics and parts under power I would highly suggest you have some one who is familiar with this do it.

Battery and/or overheating or ?


It is possible that the battery is not charging at all and can't pass electricity to the board. But if its 3yo, its probably really dead.

Also, if you can see a fan not working at all, overheating is also possible.

It is also possible that there is a tiny foreign object capable of conducting electricity, such as human hair, that gets activated at the slightest movement of the laptop by shorting some pins on your board.

So I would suggest to observe more or clean the inside of your laptop if you know how to remove your keyboard.

Just reconnect the ac adapter without the battery and switch on the lap. Presto.. Problem solved.. It doesnt power off anymore unless u remove the ac adaptor. Usefull if u hav needed files n want 2 create a backup. Still i havent found out a permanent solution to this problem. I suspect its a motherboard fault

Computer Shuts Down By Itself


It sounds like the heads that read your hard drive are deteriorating. If you have data that you need on the hard drive hook it up as a slave drive to another computer and save your data now. Because eventually you will no longer be able to access any data on the drive. Then you will have to send it to one of those data recovery places that use clean rooms to recover your data. That will be very expensive.

Or you might have a bad sector in bios. In that case, I am not sure what to do.

Help !!!!my laptop shuts down


We had some Acers do the exact same thing and we fixed them. I believe it shuts right off as a safety. Usually when the processor gets too hot it powers right off to save the laptop from burning up. First quick fix it to blow out the vents and especially blow out the heat sink vent. Also could be that the heat paste that sits between the CPU and Heat Sink could have dried up and stopped doing it's job to remove heat efficiently from the CPU. Big problem in earlier model Gateway laptops too. This can be fixed by acquiring some paste from a local tech shop and reapplying it. If you feel unsure about it, take it to a tech shop and they can do it quick for cheap if not for free. Keep me posted - Scotty
