model: ThinkPad T430s(model id: 2109)
subtype (notebook, netbook, motherboard, tablet):
does it have a free boot firmware (BIOS,UEFI,...) ?
can free operating systems be installed?
does the device prevent installing wifi cards not-approved by the vendor?
yes (see the details inside the description entry)
year of commercialization:
compatibility with free software:
Debian GNU/Linux 10 buster
tested with the following kernel libre:
video card model:
Intel HD Graphics 4000 (works with 3D acceleration)
Intel Corporation Centrino Wireless-N 2200 (it does not work)
(not specified how it works)
The laptop works perfectly on GNU/Linux with some exceptions. The Nvidia Optimus graphics dont seem to activate, but it's not an issue since it will automatically switch to Intel graphics which work fine anyway.
The one major issue is that the wifi card requires non-free firmware to work. Unfortunately the BIOS has a whitelist and prevents you from installing another wifi card. You could work around this by installing Coreboot (which is very hard on this particular ThinkPad), or use a USB wifi dongle instead.
