Solved! When your laptop gets hot is it a hardware problem?

Hello jee_90;


How hot does it get? It it how sitting idle, or only during hard usage such as playing a game?
 
uhmm when im typing a document on Ms word, browsing the internet and when I play games just like solitaire. my netbook gets hot in just a short period of time like 15 to 20 mins after the start up.
 
How old is it? Does the fan seem to work harder that it used to?
It could need a general cleaning of the cooling fan.
