CPU Overheating Laptop (nc2400)

Hi,

My 7 month old nc2400 (Core 2 Duo 1.2 Ghz Ultra-Low Voltage) started overheating while in the docking station. CPU Monitoring tools show the temperature hitting over 80C before the laptop would just shut down.

Well, I finally decided to open my computer to see if the ventilation system was clogged. I spent an hour disassembling the laptop down to the last piece, because the fan and heatsink was buried inside the laptop.

It didn't look dirty from the outside, but there inside a ventilation tube was a giant thick ball of dirt. It was impressive because of its size and density. It had completely sealed up the tube and was preventing the hot air from flowing out. After re-assembling the laptop, a feat given the number of screws, my CPU is now running at 50C -- 30 degrees Celsius cooler.

Hopefully this will serve as warning to people from buying poorly designed nc2400, and as a guide to other owners of HP laptops who find themselves with an increasingly hot laptop.


Cheers.

 

good advice there. however it is always recommended that you dont place ur laptop on an over dusty place. (esp the ones with a bottom intake fan)..
i clean the heatsink of my dell bimonthly.

 

anything computer or laptop not sitting in a clean room.....is subject to dust and lint..... just a little reminder.

 

It seems that normal customers, those who don't know AC from DC, would not venture to open up their laptop, voiding their warranty, in search of a possible dust ball. What do these people do? Does HP just keep servicing these laptops?

This is my tenth laptop, but the first one that needed to be cleaned. I've even kept some of the other laptops under my bed, the land of the dust bunnies.

 

I think HP hopes they don't send it in (if within warranty period) and buy a new one.
