In the past few days my laptop has been behaving oddly. At first it would not allow me to adjust the brightness, neither with the function keys nor the slider. This would happen after it awakened from sleep.
It also does not like to restart now. It hangs at the "Restarting" screen until I force it to turn off by holding the power button.
In, addition, the keyboard stopped functioning. This has only happened once, though.
I ran system file check from the command line. It found corrupted files, but was unable to fix them. I ran it again in "Safe Mode" and got the same results.
I tried rolling back the display adapter. This did not solve the problem either.
Any help will be greatly appreciated.
