Charging the batteries

When the power in the battery pack becomes low, the DC IN/Battery
indicator flashs amber to indicate that only a few minutes of battery power
remain. If you continue to use the computer while the DC IN/Battery
indicator flashes, the computer enables Hibernation Mode so that you do
not lose any data, and automatically turn itself off.
You must recharge a battery pack when it becomes discharged.
