[Sugar-devel] XO power management hindering collaboration

[Sridhar Dhanapalan]

It's looking to us that the aggressive power management enabled on the
XO can sometimes create confusion when children are collaborating on
activities.

Take for example a turn-based game like Memorise. If a child is
waiting for their turn, they might leave the XO untouched. In that
time, power management can kick in, and the XO stops communicating
over the wireless network. Waking up the XO (e.g. by touching the pad)
doesn't always rejoin the XO to the game properly. The whole game is
stalled because the turn cannot be completed.

Are there any ways we can manage this in our deployments? Perhaps some
guidelines to give to teachers so that they have a reasonable
expectation?

Thanks,
Sridhar
