Really not sure what's up. The laptop repair place on Clairemont Mesa
offered to diagnose the HD and put new thermal grease on the CPU for $85
(good toward parts yadda yadda yadda). Well, I've got thermal grease in my
kit somewhere, and that's 20% of the cost of a new one, so I came home.
Keep in mind that too much thermal grease is worse than too little. Some
people aren't happy till they can see it oozing out between parts.
Properly, it's only supposed to fill in the very small (as in almost
microscopic) defects in the CPU-heatsink interface. Generally about
.005" is enough. The point is not to insulate, but to facilitate thermal
conductivity.
Go to Arctic Silver's website to see how to do it properly

(Synopsis: Clean the parts first to make sure there is no skin oil, and
don't touch either surface afterwards. Use a glob about half the size of
a grain of rice; spread evenly on CPU heat-spreader using a credit card
as a spatula.)
Personal experience: using this method, I've yet to have a heat-related
problem. And I've built a LOT of PC's.
The bios says it's running at 68 C, and the laptop place said that's too
hot. If it's overheating, that could be leading to flakey HD performance
that would clear up with a cooler CPU. Supporting this idea: (1) when
warmed up, it won't even boot (2) when cooled off for a while, it boots
nicely and then goes south about 15 minutes later.
But I still don't have a laptop. Or much $$.
Fry's was advertising a Toshiba Satellite like mine new for $500 over the
weekend. Taking that as the price to match or beat, what does the list
know? Of course, if another $100 gets a *lot* more, I would consider it.
