Quick Start Guide

This manual provides essential information for the safe and efficient use of your LG 15Z90RT Series Notebook. Before using the device for the first time, ensure the battery is fully charged. Always back up critical user data to an external storage device, as SSD malfunctions can lead to data loss. When shutting down the system, wait until it has completely loaded to avoid improper shutdown issues.

Product Overview

The notebook features a front-facing webcam, IR LED, built-in microphone, keyboard, touchpad, and power button. The sides of the device house various ports:

  • Left Side: USB-C port (USB 4.0 Gen 3x2 / Thunderbolt) and built-in speakers.
  • Right Side: Headphone port (4-pole ear microphone) and USB-C port (USB 3.2 Gen 2x1).

Note that Thunderbolt devices are only supported on the left USB-C port. The 4-pole ear microphone port supports US 4-pole standards but does not support external microphones or European 4-pole headsets.

Connectivity and Ports

To connect to a wired LAN, you must purchase a separate LAN adapter. Connect the adapter to either of the USB-C ports on the PC, then connect the network cable to the adapter. The USB-C ports also support power delivery and charging.

Power and Battery Management

Use only the provided AC adapter for charging. The adapter is compatible with 100 V to 240 V power outlets. To extend battery lifespan, keep the battery level at approximately 50% if the device will not be used for an extended period. You can also use the 'Extend Battery Life' function in the LG Smart Assistant software to limit charging to 80% of maximum capacity.
