Hi all,

Have an HP Pavilion dv5. My friend wanted me to rebuild it for her. During the factory restore, the unit powered off and the case was extremely hot! So obviously a thermal issue. So i've dissmantled this beast and apart from a small about of dust, the fan and heat sink seem in pretty good condition. I'll lube the fan but is there anything else I can do to try and resolve the overheating issue or is this a known problem with this model? The CPU has thermal pads, do these "dry out"? Can you remove this and use thermal grease?

Cheers. ;)

Was the fan working when you did the factory restore?

There shouldnt be a problem with using thermal paste, I recommend arctic silver 5.

Did you have it sitting on a tablecloth or bed etc?

Not good if it does as those are known to overheat and die.

Nope. Was sitting on a coffee table with a glass top.

Yea. Are those the models that you started to accumulate on your shelf at work?

Yep plus many other models like the dv3000, dv6000 and many more.
There is a way to fix them but most people opt to buy a new machine instead.

I assume it involves reflowing of the GPU solder joints either with hot air rework or in a reflow oven, or outright replacement of the GPU (and no doubt use of the same equipment anyway)

Did you manage to get a number for the temperature?

I need to fix mine too. Might clean it. I stopped the fan cos it's noisy and the temp hit over 80 :p was sitting in table in the sun. But now with blinds drawn, without the fan it hovers under 70 - good/bad? What's the ok region for laptops? One thing I do find is that if I use a utility and put the fan to the fastest speed - it still doesn't have much air coming out but I do hear the fan going ........

Keep it elevated to allow air flow, also apparently some had problems with thermal paste, try re applying it

I have a DV5, the AMD one though with the ATi Gfx card

Pretty sure the problem was only with the nVidia chips.

It has the ATI Graphics chip in it....

This has thermal pads rather than thermal paste. The pads look like they are in good condition (no cracking etc).
