OK, no RAPL interface, so can you run "powerstat -za 1 480" instead.
The default mode for the fan is to be controlled by the firmware and not the kernel, so the kernel has no direct control by default. The alternative mechanism is to enable the thinkpad_acpi fan control and twiddle the settings either manually or by software control. By default though, one would expect the firmware do be able to control the fan correctly since that what the system designers intended to be the default fan control mode. If you do intend to try twiddling the fan controls manually, I believe the following instructions may work (but I've not tried these myself, so I can't vouch that they are correct): as root, create a new file /etc/modprobe.d/thinkpad_acpi.conf and add the following line to it: options thinkpad_acpi fan_control=1 ..and reboot. as root try the following to set the fan to the highest "engaged" fan speed: echo level 7 > /proc/acpi/ibm/fan ..hopefully that will crank the fan up to ~5100 RPM in engaged mode. you can enabled disengaged mode using: echo level disengaged > /proc/acpi/ibm/fan Essentially, "engaged" mode is where the fan speed is locked to a defined fan speed. "disengaged" mode can be used to drive the fan faster (I believe there is no feedback loop between the speed and a firmware control that sets the speed in disengaged mode).

Attempted repair, failed: Laptop has suspending ability, but I can't find the setting for the kernel to make the computer suspend instead of shutting down. Repair suggestions: 1. Persistence of session, so that everything would reappear after the restart. (this would also make updating less disruptive) 2. Do not heat the machine like crazy; speed up fans or slow down processes. (problematic Lenovo Thinkpad W500 fan on low speed right up to the fiery end) 3. Put the computer to suspend when it's too hot.
