Your XO needs power to run. Power is electricity, and there are two ways for your XO to get it: from its
battery or from a power cord. A fully charged battery should run your XO laptop for about three hours.
Using Battery Power
Your battery is like a suitcase for electricity. When you first get your XO, the suitcase is empty, so you
need to fill it up. That means you have to store some electricity in your battery before you can travel away
from a cord.
The battery icon does not indicate the number of hours or minutes remaining for the XO to run. Instead,
the icon displays a percentage of the battery life remaining.
The battery is attached to the underside of your XO.
Here's how to charge up the battery:
1. Plug the power cord into your XO.
2. Plug the other end of the power cord into the nearest power source, such as your school's
generator. A car battery may also be used, with the proper voltage adapter.
Plugging in your XO
You can use your XO when you're charging the battery or when you have a good source for power. For
power sources, you can use the generator supplied by the OLPC Project to your school or another source
of electricity.
When to charge the battery
Hovering over the battery
The battery icon fills with color, showing you the current charge, or amount of power in the suitcase. Move
the cursor over the battery icon to see more information. Also, when the battery is charging, the battery
light displays color from yellow to green. A red light tells you that the battery is running low and that you
should charge it soon.
