This happens randomly. I have an Hp Pavilion 17
When I suspend my laptop (whether by closing the lid or any other way) sometimes it does not wake up afterwards. The only solution is to force-shut down my computer by holding the power button, and then turn it back on. It's getting annoying as I can't really predict when it will actually happen. I've searched for solutions online but I couldn't find anything useful.
Somewhere it was suggested that it was an Nvidia issue, but i don't have an Nvidia card. Upgrading from 14.04 to 15.04 didn't help either.
Is there any solution to this issue?
