Has anyone seen issues like mine?
Users close their laptop (sleep) and when they open to wake it up (could be 2 mins or 2 hours of sleep), they get a black screen but can see and move the mouse pointers. It can take up to 30secs to 45seconds to see the normal screen.
Also, there laptops are running EFI 2.8
