HP laptop overheats and shuts down.

My HP G72 laptop overheats and turns itself off. What are the possible causes? I have taken it apart and cleaned it completely inside. Very small amount of dirt and the fan is working.

Hi Thank you everyone for commenting. I do not have the laptop any more. It would tun on like it normally should and everything would work perfectly for a while, but after some time whether I used it or it sat idle it would just shut down for no reason what so ever. When I took it apart the fan worked fine and was clean because I would blow compressed air into all the open vents and the fan area every month or so. Also I always used the laptop on a hard surface. Thanks again.

@vinced when you cleaned it you odf course made sure that all the air inlet vents were clean and un-obstructed. Just because you hear your fan, does not mean it runs efficiently. I would suggest you replace the fan and replace the thermal paste on the heatsink. A lot also depends on where you use your computer. Always make sure that the air vents are not obstructed. So do not use it on something like a pillow or similar.

Thank you, oldturkey03. Yes, I did check all air vents and all were clear. I used canned air and cleaned every square inch inside the laptop and checked for burn mark or any signs of something "not right", but all looked good. I have been using a cooling tray under the laptop, but it still overheats. Also, I use it on a table top with plenty of clear space around it. I, also suspected the cooling fan and the heatsink were not working properly. I removed the fan/heatsink and cleaned off the old thermal paste and with new paste. But still the same problem. A new fan is less expensive than a new laptop, so I think I will order a new fan/heatsink assy. Thank you for your help. I do appreciate it.

spesso sui modelli g62 e g72 il problema e’ il surriscaldamento della scheda video… a lungo andare il chip si distacca dalla piastra madre e comincia a dare problemi sino al punto che il notebook non si avvia piu’. E’ necessario effettuare il reballing della skeda video
