So friend, when was the last time you gave a live presentation in front of a large group of people?
It might be time to remove the batteries from your remote presentation equipment and other devices you would not want damaged by leaking batteries.
wireless mice as well if they're not being used.
batteries are better than years ago but leakage is still possible.
What about the laptops/tablets that may be left plugged in all day? Has anyone had issues with those?
