The PC system has to cool down before it can be reactivated.

Information on Hard Drive / Memory Capacity

Information on Hard Drive (HDD, SSD, eMMC) Capacity

The hard drive capacity shown by Windows is lower than that stated by the hard drive manufacturer due to a difference in calculation.

ENGLISH

Introduction / Important Safety Precautions

CAUTION

• Before using the headset, check if the volume is too high.

• Do not use the headset too long.

ENGLISH

Manufacturer Hard drive manufacturers use a decimal definition of 1 KB = 1,000 Bytes.

100 GB Storage Device (HDD, SSD, eMMC): 100,000 MB / 1,000 Bytes = 100 GB

Windows Windows use the binary definition of 1 KB = 1,024 Bytes.

100 GB Storage Device (HDD, SSD, eMMC): 100,000 MB / 1,024 Bytes =

97.6 GB

RAM Capacity

RAM capacity shown by Windows may be lower than the actual capacity because the PC uses shared memory for BIOS and the integrated graphics card.

Due to BIOS using shared memory, 1,024 MB RAM may be reported as 1,022 MB or slightly less.

If the PC has integrated graphics card, 1,024 MB RAM may be reported as 1,022 MB or less than 1,000 MB.

Adjusting Volume (headset and speakers)

Using the PC

TIP

When the PC is not used for an extended period of time, refer to the following:

• Check the battery charge level on a regular basis and keep it at 50 %. This allows you to

extend the battery life.

• If the battery is left fully charged for an extended period of time, the battery capacity and

battery running time may be reduced.

• If the battery is left fully discharged for an extended period of time, it may become over-

discharged and cannot be charged again.

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

• The battery runs low naturally even if it is kept unused.

• To increase battery lifespan, use the battery for a while before charging it rather than

keeping the battery completely charged.

• If you don't use the product for a long time with the battery completely charged, the

battery lifespan may decrease.

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

• LG Notebook frequently checks the charge level of its battery based on usage conditions,

and then calculates and correctly indicates the actual remaining level of the battery.

• The battery is wearable goods and thus the life span may become shorter with use. 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 50 °F, it is charged in a low current to

protect the battery cells. In this case, charging time may stretch to up to 32 hours.

If you use the system at a low temperature, refer to the following:

• The battery capacity may be reduced depending on the chemical characteristics of the

battery and the system may not be turned on af ter it freezes or it is turned off.

• If the system freezes or if it is not turned on, connect the AC adapter to the system and

charge the battery fully before use.

• If there is any error in the indication of the battery capacity, charge and discharge the

battery two or three times at room temperature to return to the normal operation.
