Keyboard black screen
Laptop screen blackout issue can be prevented by just taking care of few things below
Never put the laptop on longer sleep times, instead shutdown the device
Always open and close the laptop display gently as the display connections are located right at the hinge.
Keep the drivers up to date and never disable or delete drivers manually
Update the OS only when it is available officially as force update may miss the drivers and may not install correctly
Keep track of recently installed softwares.
