Hello I can't adjust my brightless anymore. I did a CCleaner earlier and when I restarted my laptop I don't see my brightness slider anymore.

The only software I am aware that modifies OEM windows/prompts and or disables them are viruses/malware. They can totally hide system settings.

Also it is rare but a chkdsk could fix this is the area of the drive that has a the .dll for it is corrupt. Would not hurt to do a chkdsk on your drive.

I had to turn on my default graphic card. But why? I want to disable it because I do not want to use the 4600 while gaming. Anyone know what is going on here?
