Laptop Display is on but black

[cronin2004]

Hello,

Recently my laptop display has been having issues displaying.  It's clearly on, but it's black.  It happened over time, and now it rarely displays. 

Extending the monitors works - but the laptop screen remains black usually.  One way I got it to display is to change the refresh rate a bunch of times until it starts to display again.  But obviously I can only do that when my monitor is extended.   I've reinstalled the AMD both AMD's and HP's driver.  I need a permanent solution.

Thank you
