I think this is a system specific issue (it depends on the BIOS).
Quoting Bbswitch's documentation:

On some machines, turning off the card is permanent and the card does
not reappear on subsequents reboots, which can result into the screen
staying black all the time, including the BIOS screen. If it occurs,
first try to shutdown, unplug power cord, remove battery, wait 30s, then
put everything back in and boot. If it's not solved, then the solution
is to reset the BIOS to factory settings. Before executing bbswitch for
the first time, it is therefore recommended to take note of the full key
sequence in the BIOS to do a reset.

On shutdown bbswitch is unloaded and should switch the discrete card back on, but apparently this doesn't work on this specific system.

  until reboot.

  Step to reproduce: Switch to intel integrated graphic driver first if you were not,
  open nvidia settings from dash or use following command:
  sudo prime-select intel && sudo reboot now

  Expected result: Able to switch back to nvidia graphic chip using
  nvidia settings.

  Actuall result: unable to swich back to nvidia driver, the 3D controller disapeared in pci list. nvidia-settings will give you empty warning prompt, checking from console gives you unkown result:
  sudo prime-select query
  unknown

  WORKAROUND: Shutdown the system then turn on, the 3D controller will
  be back.
