There is a small magnet located under where the battery is seated. This magnet activates the on/off switch inside the battery case when the battery is placed. On a small number of boards the aluminum fitting was not flush with the foam creating a gap. This results in intermittent power loss while using the board.
To fix this problem
- Peel back the top left portion of the sticker in the battery compartment
- Pry up the magnet
- Place a shim under the magnet
- Re-adhere the sticker
