X1 Carbon type 3460-1F4 / W7x64: Fn+F3 and Fn+F5 no longer work

#1 Post by dandreye » Thu Aug 30, 2018 10:50 am

Hi All,

After working perfectly fine since inception i.e. for years Fn+F3 (screen lock) and Fn+F5 (wireless) apparently stopped working on my X1 Carbon type 3460-1F4 (1st gen) under Windows 7 Ultimate 64-bit some time earlier this month (I didn't notice exactly when). Reinstalling HOTKEY/OSD doesn't help. If I go to C:/Program Files/Lenovo/HOTKEY/ and manually start TpFnF2.exe (which I suppose is what's called upon Fn+F3) the screen does lock; if I manually start TpFnF5.exe (which I suppose is what's called upon Fn+F5) I do get Wireless menu. Other Fn+Fx combinations that were also working since inception, e.g. Fn+F4 (sleep) and Fn+F8/F9 (screen brightness), still work. Is there a way to see which application (if any) is currently mapped to each of those combinations?

Versions in use:
- HOTKEY/OSD: 8.86.25
- Power Manager: 6.68.15
- PM Driver: 1.67.14.5

Many thanks in advance!

Find a program to test every single key on your keyboard, such as this: http://keyboardchecker.com/

Thank you - just done it: F1-F12 keys turn green at the first attempt. Fn key image is grayed out and nothing happens when I press the key, so I suppose Fn+Fx combinations cannot be tested.

I've also tried this one:
https://pcsupport.lenovo.com/gb/en/prod ... s/DS112679

When I run the test it first asks not to touch the KB. I click OK with the mouse and then it asks not to touch both mouse and KB. If I do nothing it sits like that for minutes with 0% progress until I click OK again, at which point the test seems to actually start, ending immediately and reporting something like "Cancelled because interrupted by mouse/KB usage". Am I supposed to not touch it for hours maybe?..
