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.

Thinkpad T30

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 | grep -A1 VGA
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?

Thinkpad X61

Issue: Wireless device recognized, not working
Details: First thought was that the integrated Bluetooth device was having some kind of hardware conflict with the wireless card. Running rfkill list showed the wireless card subject to a hardware block, which usually stems from a wireless switch. However, flipping the wireless switch (physical switch immediately below the center of the palm rest, SoftKey = Fn+F2) would bring the bluetooth up and then down, but leave the wireless as it was. Turns out, the solution was a BIOS option.
Solution

Enter BIOS (F1 on POST)
Go to Config -> Network
Set the Wireless LAN Radio Frequency option to On

And you're golden. Sheesh.

Thinkpad R61

Issue: Systems with BIOS passwords do not netboot correctly: System reboots when an option is selected
Solution: Install a hard drive, network boot should behave normally. Working hypothesis is the locked BIOS passes incorrect system information about a drive being present, and clobbers the netboot.; Working hypothesis is wrong, after cracking the BIOS password and updating to BIOS version 2.29, the problem is the same until a HDD is installed.
