But laptops often use a maker app to drive those functions. I see you tried this but is there more installed than those and W10? I've run into folk the blow up the OS with cleaners.
I recently got a used thinkpad L540, in which the previous owner mainly used linux ubuntu on. Apparently she accidentally deleted windows 10 once and had to redownload it.
Anyways, I didn't like how the fn and ctrl keys were positioned and that I needed to press fn key to use the regular function keys (f1, f2, etc), so I went ahead and did the fn-ctrl key swap in Bios and use with function lock (fnlk) on.
Things were working fine for a while, but then one day some of the hotkeys such as mute, lower volume, wifi/signal, and settings key stopped working only when I have fn-ctrl key swapped and have function lock on. If I turn the function lock off, things work fine (with the keys fn-ctrl keys still swapped) or just undo the fn-ctrl key swap, all the hotkeys work fine with or without function lock, but these two features are pretty important to me.
I've tried downloading the hotkey integration, and power management driver from lenovo for windows 10 for my model, but they didn't work.
Has anyone else had these problems or know any solutions to this?
I'm planning on leaving to China for work (for about a year) with this laptop and really would like to have this problem resolved.
