I've installed Ubuntu on a USB thumbdrive, to be used to backup (image) and partition a harddisk. I'm currently stuck at the backup-phase of my plan, because Ubuntu keeps shutting down.
From my perspective, it seems that it just shuts down, almost as if I had asked it to. I don't have any good messages in the logs, as far as I can tell, so I'm really looking for a place to start debugging. I've also been playing Minecraft off this installation, and it seems to not like that either: the same sort of shutdowns occur, but it isn't limited to Minecraft. It reminds me of a machine I saw with thermal issues, but I have no proof for this. (That machine would shutdown within two minutes if you simply ran a
while True: pass loop in Python.)
First, the hardware:
The machine is a Lenovo T500, running 32-bit Ubuntu 11.10.
Linux roy-linux-usb 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux

That first line makes me think my temperature suspicion is right. I downloaded
lm-sensors, and the output from
sensors (under CPU load of two Python threads looping infinitely):
$ sensors acpitz-virtual-0 Adapter: Virtual device temp1: +85.0°C (crit = +127.0°C) temp2: +96.0°C (crit = +100.0°C) thinkpad-isa-0000 Adapter: ISA adapter fan1: 3025 RPM temp1: +85.0°C temp2: +45.0°C temp3: +36.0°C temp4: +61.0°C temp5: +27.0°C temp6: N/A temp7: +27.0°C temp8: N/A temp9: +37.0°C temp10: +46.0°C temp11: +58.0°C temp12: N/A temp13: N/A temp14: N/A temp15: N/A temp16: N/A
The machine is warm, but I would not describe it as hot. The fans are spinning, and audibly changing speed.
I just purchased the laptop, and it is used.
