In what build(s) is this occurring? And are you using a schoolserver or not? OLPC release 10.1.3 fixed some issues with XO 1.5's waking up in response to multicast traffic on the network. This is necessary for Salut/"under the tree" usage to work with power management. XO-1's with 10.1.3 are configured by default to always stay on, as they (to the best of my understanding) historically have had an occasional issue where the network card might not reappear after suspending. In 11.2.0 both XO-1's and 1.5's currently are allowed to suspend, although I do not know if that will be the final setting. <div class="gmail_quote">On Sun, May 15, 2011 at 12:40 PM, <<a href="mailto:mokurai@earthtreasury.org">mokurai@earthtreasury.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div class="im">On Sat, May 14, 2011 10:04 am, Sridhar Dhanapalan wrote: > 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.

The more clumsy process is for the active player to exit and save, then open the saved Journal entry and share again. <div class="im"> > Thanks, > Sridhar > > > > Sridhar Dhanapalan > Technical Manager > One Laptop per Child Australia > M: <a href="tel:%2B61%20425%20239%20701" value="+61425239701">+61 425 239 701</a> > E: <a href="mailto:sridhar@laptop.org.au">sridhar@laptop.org.au</a> > A: G.P.O.
