Hi everybody:

I have a N9880 almost 4 years old, I just “upgrade it” with two new 250 GB HDD, extra 2 GB RAM and new screen (the original got dead).

Now I'm having a new problem, 3 days ago the computer shutdown itself, I thought it needs cleaning, so I cleaned with compressed air (as always).

Then I checked the temperature of the CPU (using Mobmeter in Windows and Computer Thermal Monitor in Linux) and it was +1C!!!!

Suddenly it shows the right temperature again (about 53 C), and then it got to 1C again, this is happening continuously.

Obviously when the sensor is in 1C the fans don't turn on, so the computers shuts itself off.

I searched in the forums, founding that this problem is relative common http://www.notebookforums.com/showth...hlight=thermal

This thread doesn't give a solution, I hope is not a bad MoBo . Could it be that the thermal sensor in the heatsink is broken?

Thanks in advance for your answers.

Regards.
