brownsfan019, check whether the fan is running. If yes, then it's most likely dust that collects around CPU - you have to take it to a service shop that's certified for that brand so they can take it apart and clean. That's recommended once a year for each laptop. Should be around $50-60. Do not try to take apart yourself for it's not worth it - each laptop is different and you'd need manufacturer's schematics to see where the screws are, how to dismantle display, etc.
Don't forget to share the experience once you're done. Good luck.
