Lenovo Ideapad 520S looses second screen capability


Lenovo Ideapad 520S-14IKB regularly loses the second screen capability. An external monitor doesn't display anything, and Windows does not detect the second screen at all. This laptop has two display adapters: Intel HD Graphics 620 and Nvidia GeForce 940MX. The laptop BIOS automatically determines when and for which applications to use the more powerful (and more power-hungry) NVIDIA adapter.

Delete large folders in Windows faster

Deleting large folders with multiple thousands of files using Windows Explorer can take a very long time.

Command prompt usually provides faster results, but depending on what command(s) were used it can still take quite a long time. After some experimenting, I found that the following way is the fastest one:

  • Open command prompt (cmd.exe) and navigate to the folder in question.
  • Run the following two commands:
    • DEL /F/Q/S folder_to_delete > nul
      Deletes all files
    • RMDIR /Q/S folder_to_delete
      Deletes remaining folder structure.
