It seems to be able to handle one or two recordings, then on the third it 
falls flat on its face. I told it to record Jurassic Park, and as soon as the 
recording was due to start, I got this in dmesg:

I'm beginning to suspect a power supply or cooling issue; it seems to get 
worse the longer the machine is running... 15 hours uptime and the T500 is 
basically dead now, and a reboot only brings it back into the land of the 
living for a couple of hours at most...

Now where did I put that 500W junker that came with the case...
