Public bug reported:
After the system is suspended it doesn't recover. The screen remains black, the
lid still blinks (indicating that the laptop is suspended). The power button
also doesn't start the system.
Bios version is 2.16.
A workaround for this problem is to disable USB3 support from bios. The problem
is similar ot bug report #1331077.
