I'm not sure if this is the right community to ask about this, so if there's somewhere else I should be, let me know please.

Until today, my brightness could be toggled using the action center (the 0%, 25%, 50%, etc.) However, today when I press the button, no action is conducted. I can change the brightness via other methods, but not through the action center. I tried restarting explorer, but it didn't work. Is there a fix?

  • So what software or configuration changes did you make today? – Ramhound May 19 '17 at 1:32
  • Literally nothing. I have no idea why it changed all of a sudden. – John Lou May 19 '17 at 1:34
  • I believe this week was patch Tuesday, so check, and see if any updates were installed – Ramhound May 19 '17 at 1:39
  • My last update was May 9th; My laptop is also up-to-date. – John Lou May 19 '17 at 1:42

    I think someone upvoted this, so I'll add that this problem went away after a restart. Every now and then, if it reappears, restarting helps :) – John Lou Dec 22 '17 at 15:25
