I don't know if this is relevant or not. I had the same problem with a nx6320. I found out that if I use it in an air-conditioned room having a temp below 22-24, it works fine. But it becomes unbearably hot (my temperature screenlet reports it to be around 100C). So I opened up power-management properties and set my processor policy to "Maximum power saving". The change in speed is negligible, but the temp doesn't go above 60C. If you do not have the processor power control, download a package called ubuntu tweak from getdeb.net and enable the power-management processor control option from the software.

Laptops get hot, that's what they do.


Mine got so hot that it would shut down by itself.

Thinking about it, it's still in the shop, might want to go and get it:p

This is usually due to dust.

Laptops need to be cleaned regularly. Force air through the reverse airflow path; Blow in the air outtakes or vacuum at the air intakes.

If you blow air through the laptop you should see a cloud of dust and you will notice your laptop immediately run cooler.
