Note
1. Never remove the battery pack while the Wake-up on LAN function is
enabled. Data will be lost. Before you remove a battery pack, disable
the Wake-up on LAN function.
2. After the battery pack is charged, avoid leaving the AC adaptor
connected and the computer turned off for more than a few hours at a
time. Continuing to charge a fully-charged battery pack can damage the
battery.
Charging the batteries
When the power in the battery pack becomes low, the Battery indicator
flashes orange indicating that only a few minutes of battery power remain.
If you continue to use the computer while the Battery indicator flashes, the
computer enables Hibernation Mode (so you don't lose data) and
automatically turns off.
You must recharge a battery pack when it becomes discharged.
Procedures
To recharge a battery pack while it is installed in the computer, connect the
AC adaptor to the DC IN 19V jack and plug the other end into a working
outlet.
The Battery indicator glows orange when the battery is being charged.
Use only the computer connected to an AC power source to charge the
battery pack. Never attempt to charge the battery pack with any other
charger.
