[SOLVED] Laptop facing thermal shutdown problem

[ponnus]

Hai,
I'm facing a big problem .....
After working continuously for 3-4 hours, my laptop undergoes thermal shutdown. I found that it is getting heated too much, because the fan is not working after 3-4 hours.
Does anyone knows, why this problem occurs?

Thanks

because the fan is not working after 3-4 hours

- fan stops after 3-4 hours?
- fan doesn't work at all?

In any case, it's probably a fan problem. Cleaning of intake filters, fan, heatsinks might help, possibly a drop of oil for fan bearing.
