Bug Description
Steps:
1. Suspend the computer by pressing the Sleep key(Fn+F2 on the keyboard here)
2. Press any key on the keyboard or the Power button to wake the device up
Expected results:
1. The system suspends and the Power button LED blinks
2. The system wakes up and user can log in.
Actual results:
1. The system suspends and the Power button LED blinks (OK)
2. The login screen appears and the screen is immediately turned off (NOK). User needs to move the mouse or enter a key to turn the screen on.
Additional information:
- In a few additional occasions, after performing this action several times (pressing the Sleep key to suspend the system, then wake it up), the system freezes at log in screen just before going to suspend mode. It has to be force-stopped and restarted.
- Please note that this problem does NOT happen when suspending from the User Menu or using the Power button and selecting Suspend.
