A customer in St Lucia called about a Lenovo IdeaPad S340 that started normally and accepted their Windows login, but then displayed a black screen instead of the desktop.
Task Manager was still accessible. While checking the startup entries, I found BlueStacks Services showing a group of 112 processes. BlueStacks had been installed to run WikiCamps, an Android application, on the Windows laptop.
I disabled the BlueStacks startup entry and restarted the laptop. Windows then logged in and displayed the desktop normally, identifying that startup entry as the trigger for the problem.
After discussing the options, the customer decided to stop using BlueStacks, so I uninstalled it. They are considering a newer Android tablet to run WikiCamps directly. I also completed a quick tune-up and researched options for a new laptop and Android phone at the customer’s request.
A black screen after login can have many causes. Some jobs require more involved investigation and repairs to Windows before the desktop will load again. Fortunately, this was one of the simplest examples I’ve encountered: disabling the troublesome startup entry restored normal access to the laptop.
