You’ll notice that while Airplane Mode is on, the system reboots/shuts down just fine.

I first stumbled across the solution while troubleshooting when I decided to disable the wireless adapters (Wi-Fi and Bluetooth) using the hardware wireless switch on the side of the computer before shutting down. The solution, as it turns out, is pretty simple.Īs usual, it’s a driver which is to blame for the problem. In my case, I encountered the problem while setting up around 10 Dell Latitude E7240 (LatitSeries) notebook computers for my clients.

There is no evidence present in the Event Log or anywhere else to indicate what might be to blame, and nothing on the internet that I could find references the issue. This behavior occurs following the installation of the free Windows 8.1 update. I’ve recently encountered a pretty new issue involving some Dell laptops where the system will simply hang at a black screen, completely blank, when a shutdown or restart is initiated.
