I have a Lenovo IdeaPad U460s 0885 - Core i3 330UM 1.2 GHz when i try loading sims 3 it overheats and shutsdown

Hello,

Laptops shut down when they overheat to protect themselves from damage due to heat. Can you hear the fan running on the laptop? If not, then take it in to a shop to be looked at, or contact the manufacturer if it is still in warranty.

I will assume that the fan is probably running at full blast all the time. if this is the case, then you probably need to clean the heatsink on your laptop. How?

An air compressor is best for this if you have access to one. A can of compressed air may work, but usually does not have enough pressure to clear it out.

Your laptop fan draws air in through the bottom of the laptop and pushes it through a heatsink. The heatsink is a piece of metal that draws heat away from the cpu (main chip on the laptop) and allows the fan to cool it. The fan blows air between tiny metal "fins" on the heatsink. You will probably be able to find where your laptop blows out the hot air.

Find where the hot air comes out of the laptop, and blast compressed air into that place. You will probably see a cloud of dust come out of the bottom of the laptop. Keep blasting air until no more dust comes out. Once this is done, the laptop should run quieter and cooler. Let me know if this does not fix the shutdowns.

Hope this helps!
