Hello folks,
I've got an HP Probook 6450b. Wonderful machine, but it's running hot. Right now, on Win7 x64, it's idling at 49d (Celsius), which is fine. But I just did some Windows updating, and immediately afterward the dotnets went into their Optimization routines. For maybe fifteen minutes the processor was running at 25% capacity (according to Task Manager), and that drove the temps up to 85d.
The history of this machine is that it was dropped, causing some cosmetic damage to the left-front corner of the palmrest. I don't know if that's relevant. When I got the machine it shut down a couple of times, so finally I took it apart. I found that a very sloppy attempt had been made to re-paste the processor. So I redid that half an hour ago, and here I am. The case is still semi-open, allowing for plenty of airflow (though that might work against cooling the heatsink via the fan, eh?)
Essentially I've got a machine that is great at low load, but very fragile at higher load. As soon as the load increases, the fan revs up more than I would expect. It hasn't shut down yet, since the re-paste.
My question is this: do you think this is a problem that would be solved by a processor replacement, or is there something else I should consider? I'd appreciate some perspective here. Thanks much.
