Working on a laptop that came in yesterday. Owner complains it works for a while then shuts off. I start checking it out... It runs fine for random amounts of time. Typically, if you start it up and just let it idle in Vista, it'll run fine indefinitely. But, once you start doing something (spyware scan, for example), the computer will run for a bit longer and then shut off.
CPU is a T2250 Core Duo 1.73ghz. I installed speedfan to check the temps. At idle, it runs about 56c. Under load, it'll touch 80c, and that's where it shuts down. It does appear that the computer shuts down properly when this happens, as the screen fades, and then it turns off.
Now, here's what gets me to believe the heat pipe is faulty... the entire time, the fan will be running, but the vents are both blowing cool air (ambient temperature, I should say). I have, of course, checked all the fins, and they are completely unblocked. When the computer shuts down, the heat pipe around the CPU is very hot... but the actual heatsinks are barely warm to the touch.
Should I take a leap and get a new heatpipe assembly for this thing?
