Never remove the battery pack while the Wake-up on LAN function is

Wake-up on LAN function.
Charging the batteries
When the power in the battery pack becomes low, the DC IN/Battery
indicator flashes 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 enters Hibernation Mode so that you do not
lose any data, and automatically turn itself off.
You must recharge the battery pack when it becomes discharged.
Procedures
To recharge a battery pack, connect the AC adaptor to the DC IN 19V jack
