Laptop keep shutting down?

Question

I'm using a lenovo laptop. When i start to surf the internet or open a program for around 10 minutes, my computer just auto shut down by itself. Computer doesn't seem to be overheat, and my fan doesn't make any loud weird noise. I've tried to scan for virus, but when it scan half way. It just auto shut down. Whats wrong with this laptop?? How can i fix it??

Answer 1

Heat is the biggest culprit when puters just shut down or crash. First thing is to make sure the fans and vents are clean and clear. Get a couple cans of compressed air and blow out the vents and fans. The best way to blow the fan and heat sink is to blow the air into the exhaust vents. Hold your hand over the vents and find which one is blowing air out. It is normally the one you can see one the side or back of the laptop. You can place the laptop on a towel upside down so you can see the inlet vent and place the tube from the can of compressed air at the exhaust vent. Press the trigger on the can and move the tube back and forth across the outlet vent. Make sure you can feel the air coming out of the inlet vent. If you have someone to help, you can get someone to hold a vacuum hose near the inlet vent while you're blowing air in the outlet vent to help catch the dust coming out. You can find some good videos on YouTube on how to keep a laptop clean.

It may be updating over and over again. Leave it to sit next time it restarts. Do not turn it back on for 5 minutes. See if this fixes it.

If it's more than two years old, it probably IS overheating. Try using a base with a fan in it. That solved the problem with my HP.
