- fan issues
YAY FIXED!
- SIMPLE
append:
acpi=force
to the grub boot options.
then:
echo 0x2f 0x07 > /proc/acpi/ibm/ecdump
typing that command and redirecting that output to the embedded control dump (ecdump) file will turn that fan on at it's maximum speed.
- Notes
this simple script found here:http://www.thinkwiki.org/wiki/ACPI_fan_control_script and take care of any unnecessary end-user interaction with the fan control. other useful information can be found their as well, about controlling the fan.

RAM slot failure, it's a solder failure, usually starts in the second slot and worsens from there. http://www.thinkwiki.org/wiki/Problem_with_failing_memory_slot As-is these machines.
Thinkpad R60
In the frame buffer environment (pre-GUI) the top portion of the screen has a stripe of garbled (red) characters. This fix worked for this chipset:
lspci -k
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X1400 Kernel modules: radeon
sudo gedit /etc/default/grup
Edit the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to read GRUB_CMDLINE_LINUX_DEFAULT="radeon.modeset=0 quiet splash".
Run
sudo update-grub
Reboot. Is fixed, no?
