Tell me how long since you cleaned it's vents, heatsinks and fans?
Many were never told it's a yearly thing we must do.
After you clean it up, how about a nice laptop cooling pad?
My Gateway 3560 Laptop seems to get hot and shuts off. The fan is running. Does it need a new fan? It is not going into hibernation. It takes at least 5 hours for it to do this. If I need a new fan can I change it myself?
