Jose has a Dell 2 in 1 laptop and the screen goes intermittently black. Leo says that it's a common issue with 2 in 1s because the ribbon cable gets "pinched" as it gets bent back and forth. Eventually, it frays and breaks. The good news is, that it's an easy fix to replace it. Before you do that though, update your video drivers. That could fix it as the drivers can get corrupted. But if the problem persists, it's a hardware issue.
