Re: [PLUG] OT dell laptop repair

Hash: SHA1


In general, I've experienced that Dell has had heat dissipation problems over
the years across their product lines.  I've had mixed results with Dell laptops.
 An earlier one suffered strange  problems and died early.  A friend's Inspiron
died a fiery death while sitting on his desk.  Dell replaced that one VERY
rapidly!  My daughter's old P-4 Dimension 3000 tower throws off so much heat
that it could double as an easy-bake oven.  On the other hand, my most recent
Dell laptop, a Vostro rescued from the parts/trash heap, has performed well [1].

Based on your description I'd suspect the CPU cooler has somehow become partly
detached from the CPU.  This dramatically increases the thermal resistance and
results in the processor overheating almost immediately after power-on.

When you disassemble the laptop, make sure to have some new high quality thermal
paste on hand.  Take the time to remove the cpu cooler from the cpu, carefully
clean both with an appropriate solvent, and apply the new thermal paste.  Double
check that it's seated firmly on re-install.

Good luck.
