Being safe with the XO
Your XO laptop is checked for safety against the European Union's RoHS Directive which ensures that it
contains no hazardous or unsafe materials. Its NiMH batteries contain no toxic heavy metals, plus it
features enhanced battery management for an extended recharge-cycle lifetime. The XO also uses
alternate power-charging sources, such as a car battery, with a modified adapter. Ask an adult for help
with chargers other than the provided AC adapter.
You might also be concerned about protecting your XO laptop from a computer virus. The unique security
system isolates each Activity so that a virus cannot easily infect the XO laptop. Currently you do not need
to install separate anti-virus software or firewall software.
Please realize that the XO laptop is designed for easy-to-use wireless connection to the Internet and
other networks, but you should be careful and ask your teacher or parent for help and protection. They
need to know that "Internet access must be purchased separately through an independent Internet
Service Provider (ISP). In selecting an ISP, you should remember that, in addition to the many wonderful
sites and educational resources on the Internet and World Wide Web, there are places where you
wouldn’t want your child to go and people you wouldn’t want your child to meet. That’s why many ISPs
offer “filters” that assist you in monitoring and/or controlling your child’s Internet access. So your child can
have a safe and healthful experience, OLPC FOUNDATION RECOMMENDS THAT YOU USE AN
APPROPRIATE INTERNET FILTER, REMAIN INVOLVED IN YOUR CHILD’S USE OF THE INTERNET
AND, OF COURSE, STAY ACTIVELY ENGAGED IN YOUR CHILD’S EDUCATION."
By our estimates, your XO should last at least five years. To help ensure such durability, take care of it
well.
