X31 Freezes when Running On Battery

[zignet]

The X31 freezes after about 2 minutes when running on battery. I have tried another battery and this did not resolve the problem
The machine starts up ok but then locks and there is no way to turn it off.

You may want to go into the power settings in windows and check how the systems is set up to operate when it is running on the battery.
