I've got one of the old asus laptops L1400b :)

After accidental droping of laptop... it start to overheat CPU... fan is speaning right... everything seems to be ok... but CPU is about 50-80 C always... and it shots itself down from time to time... i believe to prevet damaging CPU... what could be done?... before CPU's heat was at about 40-60 at max....

I know probably it's easier to buy new laptop but I love my old friend as it always worked smooth and nice and it's enough for everything I do, even some of the basic photoshop staff :)

any suggestions?

The first thing to try with an overheating laptop is...

a) Turn it off
b) Open the backplate that leads to the cpu/fan area
c) Use a can of compressed air to blow out the wad of dust that is most likely blocking the fan.

Ragnor, I've done it at first place... but overheating only appeared after accidental drop of laptop :) So I rather issume that something is simple damaged... like CPU's heatsink or something, because apart from overheating.. laptop functions normaly.

In the realm of theoreticalness, the thermal paste may have detached itself somehow. The fansink may not be connecting with the cpu anymore. And it is possible that a wad of dust has dumped itself into the cpu fan.

That reminds me I have to do it for my Acer laptop. It reaches 100c when watching flash videos. A pain.

The dust comment is really true. I have a Windows Home Server and it was shuting itself down for a while. I openeded, cleaned the fan, removed dust, reapplied the thermal paste and never had this problem again.

Mauricio, you was right.

I finally got my hands on new thermal greaser from DSE. applied it and now everything works as before :) at least for now... I've done CPU crash test and temperature was not higher then 65 C

thanks
