my 250N is now 4 years old. was having shutdown trouble like described above. with instructions from dell's web site, i took it apart and found that the internal part of the cpu/power supply heat sinks were 20% blocked by dust. vacuuming it out from outside was impossible (i tried). i carefully used a vacuum cleaner with a straw. i did not distrub the cpu. it's been working correctly for 2 weeks now. it was shutting down within 1 hr. it started when summer got really warm. once the problem started happening, i could get very little work done...have used it extensively now and left it on overnight without incident. dell's support didn't provide any clues on this. thank you all for your insights.

Thank you everyone
I took out the heatsink and warmed it up with a heat gun and did not need to use razor blade to separate cpu and heatsink.I sanded heat sink to smooth surface and then I bought thermal paste to apply on cpu before putting back together. When I reassembled and then restarted and the cputhe fandid not even come on (I thought I had forgotten to connect it) the cpu is now running at 28 celcius and the fan rarely even comes on
What a difference! I was going to throw this unit out as I have already purchased another laptop HP this but now I guess I have two
Thanks again to all who helped with info
