Careful stewardship of battery power is critical.
This page is a work in process, collecting information related to power management on OLPC.
In addition to effectively managing the power that is in the battery, we need to think of ways in which more power can be added to the battery. The charger included with the OLPC should only be considered as a beginning. In fact, it is the most fragile part of the hardware package because of the moving parts and the stresses and strains of use. The Battery and power page discusses many alternate power sources that could be used to supplement the existing charger.
