Upgrade to 10.04 failure to boot PC overheat

[ceaxer]

After I upgraded to 10.04 using the prompt for an upgrade. Ubuntu failed to boot. PC starts but during boot hangs after ubuntu symbol and screen goes black and PC overheats. Same problem when booting off CD. I removed HDD and rigged it up as a USB) but can't read the the disk in windows. The PC works fine using old windows HD. What do I do?

PC:IBM Thinkpad G40 (laptop)
Ram: 1Gb

Greetings,
I have similar overheating problem with Lenovo 3000 Laptop -
with an Intel T2300 Dual CPU (1.6 GHz).

I'm not sure how to get Hardware info for the temperature and fan cooling system.

Microsoft says the PC is "ACPI Thermal zone" and is Microsoft ACPI-compliant-
on the 82801 GBM LPC interface and on the processor.

I installed Ubuntu 10.10 as a dual boot (with windows XP.)

Using the xsensor package. one of the core temps said 64 degrees C.
The variable-speed cooling fan was barely running.

I did a restart and used some free-trial-ware sensors with XP.
The fans ran at a higher speed and the core temps dropped to 53 degrees C.

I have looked for a fan control package but did not see it.

Can anyone please point me to a fan control package that runs on temperature feedback?

Thanks in advance,
Jay E. :P
