Laptop shutting down unexpectedly

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

test all leads that attach to your hard drive including electrical extensions, 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 they could be faulty

make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty ?

make sure the CPU central processing unit has thermal grease and a dust free secure seating

even something as small as an electrical extension or a faulty fan lead can cause this problem computers need all of the data and electrical current to travel through every working device and to have an end for a computer to be able work properly

could be a memory dump you might have to many programs running at one time putting to much stress on the cpu not having enough ram will do this

if you right click in the bottom toolbar select task manager applications you will see whats running also processes you will see whats ticking over if you see something running that should not be select end now you might even uninstall that program and some unnecessary programs

check your computer ram and cmos battery to make sure they are securely seated and the battery has plenty of charge

some motherboards cmos batteries are soldered in

hope it helps

Check the cooling fan. Not just the fan itself but all the airways and metal fins that it blows air over. This often requires removal of the fan itself. PC and laptop fans act like little vacuum cleaners!

Due to the heavy processing the PC heats up. Excessive heatup beyond usual is alarming and PC shuts down by itself when the processor/ CPU temperature exceeds the safe temperature limit. There are mainly two reasons for heatup.
Heating issue generally occurs due to fan failure, which may damage the system, if not checked and resolved properly. Another most likely cause of overheating is the dust present inside the PC, which clogs the fan and heatsink. As you have mentioned that the fan is not running, most probably the fan has gone dead or it may have stopped working due to clogging with dust and hence it needs cleaning or replacement. To do so, you need to purchase a new fan and disassemble the laptop to replace the fan. To replace the fan, you have to disassemble the laptop and for that you need to have the laptop repair manual that can be downloaded here.
(I think that you have HP CQ60-419WM Laptop). The repair manual contains all the information as well as graphic illustration about disassembling and replacing the fan. Please refer to Page 4-41 for complete details.

If you are able to work inside such electronics and have some disassembling experience, you may try to do it yourself. However, if you have no experience, it is strongly recommended that you seek professional help from HP authorized repair/ service professional.

Hope it helps! Good Luck! Thanks for using Fixya!

Please refer to manual and run system restore to system default settings as if it was from the package.

Cheers.

When you encounter about this issue this is overheating problem maybe the CPU fan is not spinning and faulty already, you need to check the CPU fan and replace a new one.

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.

Hi..

If the laptop shutdown maybe it cause overheating.

laptops/notebooks tend to overheat more quickly the desktop resulting in shut down, try a laptop/notebook cooling fan

Most proably it is a main board problem. Contact authorized service center.

This sounds like the cpu fan assembly go to Gateway and enter the model in the support then download the system diagram so you can remove the casing it would take me forever to type the inst. once you have removed the cover put you hand over the cpu fan assembly and check for airflow
If you are afraid to diass. your comp. take it to a pro.

I want to try a very simple thing, cause it happened to me, while I am working on my computer , it shut down unexpectedly... cause the processor is working with its full performance and no enough cooling around the laptop. so while I move to other place and also I raise the laptop a little bit from the back to let the fans (bottom of the laptop) works perfectly .
try to open it again and do so.... may be it is a so simple thing that was far from your mind like I was before... good luck
