Hello,
Yesterday I have bought Inspiron 7567 with preinstalled Ubuntu. I have added an M.2 SSD and installed Windows 10 FCU 1709 x64 and some things do not work within it.
1) The manual says to use Fn+H to configure the front status indicator for power state or hard drive activity. In my case this switch does nothing and the indicator is always flashing for hard drive. Interesting, that right after buying the laptop, it was actually showing power state, but it changed somehow and I cannot restore it.
2) The keys Fn+F11/F12 do not affect screen brightness at all. Changing brightness in Windows Mobility Center doesn't work too. I can change brightness in BIOS only.
3) Quickset application doesn't open. I see two icons in the system tray: "9" which responds to NumLock, and greyed lock which does nothing. Both icons do not react to left and right, single and double clicks. I have tried to remove and reinstall Quickset, it didn't change anything.
I have found a similar question on this forum, but there is no solution: en.community.dell.com/.../21001802
