							Extending battery lifeTo maximize the life of your battery packs:
At least once a month, disconnect the computer from a power source and operate it on battery power until the battery pack fully discharges. Beforedoing so, follow the steps as detailed below.1. Turn off the computer's power.2. Disconnect the AC adaptor and turn on the computer's power - if it
does not turn on then go to Step 4.3. Operate the computer on battery power for five minutes. If you find
that the battery pack has at least five minutes of operating time, continue operating until the battery pack is fully discharged, however, if
the  DC IN/Battery  indicator flashes or there is some other warning to
indicate a low battery condition, go to Step 4.4. Connect the AC adaptor to the DC IN 19V jack of the computer, and to a wall outlet that is supplying power. The  DC IN/Battery indicator
should glow amber to indicate that the battery pack is being charged, however, in the event that  DC IN/Battery indicator does not glow this
indicates that power is not being supplied - check the connections for the AC adaptor and the power cord.5. Charge the battery pack until the  DC IN/Battery indicator glows
white.
LAN
The computer has built-in support for Ethernet LAN (10 megabits per
second, 10BASE-T), Fast Ethernet LAN (100 megabits per second, 100BASE-TX) or Gigabit Ethernet LAN (1000 megabits per second,
1000BASE-T).
This section describes how to connect/disconnect to a LAN.
The Wake-up on LAN function consumes power even when the
system is off. Leave the AC adaptor connected while using this feature.
The Link speed (10/100/1000 megabits per second) changes
automatically depending on the network conditions (connected device, cable or noise and so on).
