# Using AC Adapter and Battery

To supply power to the notebook PC, AC adapter and Battery pack are used.

This section describes the procedure that the user should take initially for a new system.

## Using AC Adapter

The AC adapter is used to power and charge notebook PC.

The provided AC adapter can be used from 100 V to 240 V.

1. Connect the AC adapter to a power outlet with the power cable.

2. Connect the adapter to the machine.

   1. AC Adapter

   2. Power cable

3. Adjust the LCD panel to the most comfortable angle.

4. Press the power button to turn on the machine.

Tip:

- You need a different plug to use the AC adapter on 110 V. (The extra plug for 110 V is sold separately.)

CAUTION:

Do not leave a liquid container on the computer.

- The system may be short-circuited and damaged.

Note:

Please use an AC adapter certified by LG Electronics™.

- Otherwise, an explosion or fire may occur.

- It may cause a problem in battery charging or system operation.

When you use an AC adaptor, follow the below directions.

- Avoid humidity and heat above 60 ℃ as in cars or saunas.

- Do not disassemble or modify the AC adaptor.

- Do not twist the AC adaptor plug.

- When you connect the AC adaptor, do not forcefully push the plug.

## Using Battery Pack

1. Turn the machine over to see the battery pack chamber and equip the pack.

2. Open the machine and turn the power on.

3. Check the battery state.

   - When the AC adapter lamp is blinking, charge it fully with the AC adapter before using it.

4. Remove the battery pack as shown in the diagram below.

CAUTION:

Use batteries certified and acknowledged by LG Electronics Inc™.

- Uncertified batteries may explode.

- Ensure the power is off before changing the battery pack.

Keep the battery pack removed when the machine is not in use.

- Otherwise, a fire and product damage may result.

Note:

The battery may explode due to excessive heat, causing fire. For a safe and efficient use of battery, follow the below directions.

- Do not short-circuit the battery.

- Keep the battery out of reach of children.

- A visible swelling of the battery pack indicates a possible danger. When this occurs, contact your local vendor or service center immediately.

- Use only a certified and designated recharger.

- Keep the battery pack away from heat. (Never put it in a microwave.)

- Do not leave inside a car under the summer heat.

- Do not leave or use at a hot and humid place like a sauna.

- Do not use the machine placed on a heating blanket or other heat reserving materials.

- Do not leave the machine turned on inside a closed space.

- Make sure that the power ports are not touched by any metallic objects like a key, coin, necklace, and watch.

- Use only a lithium secondary battery certified and guaranteed by mobile device manufactures.

- Do not disassemble or modify the battery. Do not compress or pierce the battery.

- Do not apply shock to the battery. For example, do not drop the battery from a high place.

- Keep the room temperature between 0 °C and 60 °C. Do not expose the machine to the heat hotter than 60 °C.

- Keep the machine dry.

- When you are not using the battery, remove it from the notebook PC. When you haven't used the battery for a long time, discharge and recharge it a few times before using it.

- Do not discard the battery arbitrarily as you are requested to follow the local procedure for discarding the battery.

- Before using this machine, read this guide carefully.

Tip:

For more efficient use of the battery, read the following carefully.

- Natural discharge: The battery runs low naturally even if it is kept unused.

- Periodical full (dis)charge: Repeated recharge in midway shortens the running time gradually. To lengthen the span, charge and discharge the battery to the fullest once or twice. For optimal use, execute the full charge/discharge every 30 to 60 days. Still better, recharge the battery after it has run out.

The battery capacity may change due to chemical reactions during charge and discharge.

- The system checks the charge status of LG batteries frequently, and then calculates and indicates the actual battery duration on the current system setup.

- The battery is wearable goods and thus the life span may be getting shorter as used. The battery running time may also become shorter accordingly.

- When the battery is fully charged, the machine stops recharging. It resumes recharging when the battery charge rate drops below 95 %. This feature secures the safe and efficient use of the battery.

- When the temperature of the battery drops below 10 °C, it is charged in a low current. In this case, charging time may stretched to 32 hours or longer.
