Hello-
When the airplane is on the ground and I connect ground power, power will stay on for a little while as I do my pre-flight checks and enter my flight plan. However, after a few minutes, ground power disconnects automatically, and I am not able to re-connect using the EFB. I've tried to resolve by powering up the APU ahead of doing any other tasks, but when I try to start it ground power again disconnects automatically and I am not able to re-connect it again via the EFB. By reconnecting via the EFB I mean clicking on the cart icon. When I click on it, it does not react.
Can you kindly advise?
Thank you!
