Data for the X201 users:

Generic

3G/UMTS Modules

Firmware link (from archlinux aur packages):

Build():

  • cabextract sp48568.exe
  • cp Qualcomm/QCImages/Source/Packages/6/*.mbn /usr/lib/firmware/gobi/
  • cp UQCN.mbn /usr/lib/firmware/gobi/

From (the French) Win7 Copy these 3 files into /lib/firmware/gobi

  • C:\Program Files (x86)\Qualcomm\Images\Lenovo\UMTS\AMSS.mbn
  • C:\Program Files (x86)\Qualcomm\Images\Lenovo\UMTS\Apps.mbn
  • C:\Program Files (x86)\Qualcomm\Images\Lenovo\0\UQCN.mbn

GPS

The Qualcomm Gobi 2000 in these laptops also supports GPS (with or without a SIM card.) However, to enable this, you will need to have a Windows install either directly or in a VM that supports USB passthrough. You'll need to install the driver as per above, and the ThinkVantage software from http://support.lenovo.com/us/en/downloads/ds015017 from which you can enable the Auto-Tracking feature that enables GPS.

After that you can:

echo "\$GPS_START" > /dev/ttyUSB2
# use GPS
echo "\$GPS_STOP"  > /dev/ttyUSB2

Coreboot

Memory upgrades

According to http://www.thinkwiki.org/wiki/Unofficial_maximum_memory_specs it might not be possible to upgrade the RAM further than 4GB.

Tested configuration was 2x 4GB: Corsair 1333MHz 9-9-9-24 1.5v (CMSO4GX3M1A1333C9) on ThinkPad X201 3680-PBG with ID 6QET70WW, BIOS version 1.40 and Embedded Controller version 1.15. I have not checked my model/BIOS yet, but JFYI.

Powersave

Powertop suggested a bunch of tweaks, I listed them at https://gist.github.com/realitygaps/c7d5493b10becd1de873

Windows

If installing via an usb drive is failing, you can try a pxe install, following this tutorial: http://s205blog.wordpress.com/2012/09/29/windows-7-pxe-network-install-turorial/
