NOTE
• 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 do not use the product for a long time with the battery completely
discharged, 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 10 °C, 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 after 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.
