Thinnkpad T20/T21

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. Lynnae 22:58, 6 September 2012 (UTC)
