I'm considering to buy a Lenovo Thinkpad T440s and to install Linux on it.
According to the user guide and photos of T440s, to use F1-F12 you have to hold down the Fn key, or use Fn+Esc to enable "Fn Lock"(FnLk).

Also mentioned in the user guide, there are only three settings in the "Keyboard/Mouse" section in BIOS/UEFI configuration (aka. ThinkPad Setup):
- TrackPoint (Enabled or Disabled)
- Trackpad (Enabled or Disabled)
- Fn and Ctrl Key swap (Disaabled or Enabled)
No settings about F1-F12.
In this review from a Chinese forum, someone wrote:
which translates into:
If you want the old way back, just press Fn+Esc to get a FnLk with the driver installed. This configuration keeps even if you reboot the machine.
I asked this question on another Chinese bbs and got a negative feedback: (translated)
FnLk does not work on Windows if no driver installed.
Can anybody who has a T440s tell me whether FnLk works with Linux? Perhaps with some kernel module?
