Baffling disappearance of brightness adjustibility.

The ability to change brightness on My MSI Notebook with Windows 10 has mysteriously vanished. I used to use the FN+ brightness keys up and down to make adjustments, but it stopped working, yet strangely, the FN+volume buttons still work. When I go to Settings>Display, it's not there either. I've tried everything I can think of? Any ideas of what happened or how I can fix this?

Also, my sleep function has vanished too. Now I only have the options of shutdown and restart. I can put it to sleep with a quick push of the power button, but the option has vanished from the start panel.

Did the video driver get updated by any chance? That's what broke my brightness control... Had to do a system restore to fix it. The loss of sleep option is extra weird though.. Does it still appear in the menu that appears when you go to desktop and press Alt-F4 ?

Thank you for the reply. I'm not certain whether it coincided with any video update, but it's a clue. Pressing ALT-F4 results in a menu opening with options to: Switch user, sign out, shutdown, and restart. There is no sleep option. I will perhaps try system restore.

Some good news. An automatic Windows update resolved the problem.

any specifics as to that windows update? did it contain a gpu driver or system bugfixes? glad it got resolved though!
