Battery Usage and Maintenance

- Long-term Storage: If the PC will not be used for an extended period, keep the battery level at approximately 50%.
- Extend Battery Life: Use the 'Extend Battery Life' function in the 'My gram' or 'LG Smart Assistant' software to limit the maximum charge to 80%.
- Charging: Avoid keeping the battery completely charged at all times; use the battery for a while before recharging.
Getting Started
Checking Components: Ensure your package includes the PC main body, adaptor, and power cable. Note that some models may include additional components like LAN or HDMI adaptors.
