I recently started having a new problem where the monitor on my all in one Envy Touchscreen Rove will not wake up after sleeping. To the best of my knowledge, the computer powers up and seems to be functioning, but the monitor remains asleep. Neither pressing the on/off button, moving the mouse, or pressing any keys on the keyboard seem to wake the monitor. When I hard stop the computer by holding down the on/off button and then reboot the system, everything starts up fine. It has been upgraded from Win8 to 8.1, but i don't believe that's when the issue started.
I've reviewed several similar problems, but none seem to mirror this exact issue. Any guidance would be appreciated.
