Extending battery life
To 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.
Replacing the battery pack
Please be aware that the battery pack is classified as a consumable item.The operating life of the battery pack will gradually reduce throughrepeated charging and discharging, and will need to be replaced when it
reaches the end of its operating life. In addition to this, you might also
replace a discharged battery pack with a charged spare when you are
operating your computer away from an AC power source for an extended
period of time.

							This section explains how to remove and install the battery pack, andbegins with the removal process which is detailed through the following steps.Do not remove the battery pack while the computer is in Sleep Mode.
Data is stored in RAM, so if the computer loses power it could be lost.
In Hibernation Mode, data will be lost if you remove the battery pack or
disconnect the AC adaptor before the save is completed.
Do not touch the battery release latch while holding the computer or the battery pack might fall out due to the unintentional release of the battery release latch and cause injuries.
Removing the battery pack
To remove a discharged battery, follow the steps as detailed below:
1. Save your work.
2. Click  Power in the  Settings  charm, and then click  Shut down while

LAN The computer may have 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 amalfunction 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.
If you are using Fast Ethernet LAN (100 megabits per second, 100BASE-
TX), be sure to connect with a CAT5 cable or higher. You cannot use a
CAT3 cable.
If you are using Ethernet LAN (10 megabits per second, 10BASE-T), you can connect with a CAT3 or higher cable.

							Connecting the LAN cableTo connect the LAN cable, follow the steps as detailed below:Connect the AC adaptor before connecting the LAN cable. The ACadaptor must remain connected during LAN use. If you disconnect the AC Adaptor while the computer is accessing a LAN, the system may
hang up.
Do not connect any other cable to the LAN jack except the LAN cable.
Otherwise, malfunctions or damage may occur.
Do not connect any power supplying device to the LAN cable that is
connected to the LAN jack. Otherwise, malfunctions or damage may occur.
1. Turn off the power to all external devices connected to the computer.
2. Plug one end of the cable into the LAN jack. Press gently until you hear the latch click into place. Figure 4-7 Connecting the LAN cable

3. Plug the other end of the cable into a LAN hub connector or router.
Check with your LAN administrator and hardware or software vendorbefore using or configuring a network connection.
Additional memory module You can install additional memory into the computer in order to increase
the amount of system memory that is available. This section describes how
to install and remove optional memory modules.
You should place a mat beneath the computer in order to prevent the
computer's lid from becoming scratched or damaged when you areinstalling/replacing the memory module. In this instance you should
avoid mats that are made of materials that hold or generate static
electricity.
When installing or removing a memory module, you must ensure that
you do not touch any other internal areas of the computer.

Be careful not to let screws or other foreign matter fall into the
computer. It could cause malfunction or electric shock.
Additional memory module is a precision electronic component that
may be fatally damaged by static electricity. Since the human body
can carry static electricity, it is important that you discharge yourself
before touching or installing any additional memory modules. To
discharge your body’s static electricity, simply touch any metal close to
you with bare hands.
Use a point size 0 Phillips screwdriver to remove and fasten the screws -
the use of an incorrect screwdriver can damage the screw heads.
