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.
Do not install or remove a memory module while Wake-up on LAN is
enabled.
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).

LAN cable types

The computer must be configured properly before connecting to a LAN.
Logging onto a LAN using the computer’s default settings could cause a
malfunction in LAN operation. Check with your LAN administrator regarding
set-up procedures.
If you are using Gigabit Ethernet LAN (1000 megabits per second,
1000BASE-T), be sure to connect with a CAT5e cable or higher. You
cannot use a CAT3 or CAT5 cable.
