My experience with Lenovo Laptops (I've got a 3000 N200) is that the fan
control is performed by the BIOS. Typically there are periodic System
Management Mode interrupts into the BIOS and the fan is controlled by
this. So, the issue may be that there is a sensor fault, or the BIOS is

Hi Jeremy,
The machine was switched off overnight in both cases. With regard to the
ac adapter I actually can't remember. I didn't check that, but normally

for that particular working bo
Hi Hugh,
when you mean "cold boot", was the machine off for some time beforehand?
I wouldn't be surprised if the CPU temperature was around 87°C after
doing some computational work, but this would be very strange if the
machine had been off before booting.
If your machine was indeed off before th

Hi Laserulo,
Looking through your logs, I see one important difference:
>From the non-working dmesg log:
ACPI: Thermal Zone [TZ00] (87 C)

ACPI: Thermal Zone [TZ00] (12 C)
- looks like the working boot reported starting at 12°C, but the non-
working boot starte

Laserulo: the output of the 'dmesg' command (when working and non-

They were when the machine booted correctly. The fault is intermittent.
I cannot make it happen. Which outputs do you want and I'll send them
when it next occurs?
