(Be sure to read Chapter 2 for information on powering your system.)
The battery power may be low. If you have a second fully charged battery, use it to replace the one in the computer and recharge the original battery.
If you replace the battery and the computer does not work properly, the new battery also may not be fully charged. Recharge this battery until it reaches its maximum capacity.
When the charge light is flashing orange, the battery may not be installed properly. Try removing and reinstalling it.
Connect the AC power adapter to the computer and plug the adapter into an electrical outlet. You may not have used the battery in a long time (three months or more), and you may need to recharge it.
When you find that, over time, the battery is losing its charge faster, it may be reaching the end of its life. You may need to replace it with a new battery.
