Default Run shift without battery?

I have seen this video of someone running their shift without a battery installed, he never actually explains the process but mentions the BIOS lock that disables the device when no battery is present or battery level warning.

Anyone have any idea how to achieve this? I have emailed the videos creator with no luck -_-
