This document serves as the owner's manual for an LG Notebook, specifically the 14Z90R Series. It provides essential information for the safe and convenient use of the product, covering setup, operation, and troubleshooting.
Function Description
The LG Notebook is a portable computing device designed for general use. It features a main body with a display, keyboard, and touchpad, allowing users to interact with the Windows operating system. The notebook is equipped with various ports for connectivity, including HDMI for external displays, USB-C™ for data transfer, power, and connecting a LAN adapter, and standard USB ports for peripherals. It also includes a headphone port for audio output and a security keyhole for physical security. Built-in speakers provide audio output, and a webcam with an operation status lamp, along with a built-in microphone, supports video conferencing and other multimedia functions. An IR LED is also present, though its specific function isn't detailed in the provided excerpts.
The notebook is powered by an AC adapter, which charges the internal battery. The USB-C™ port supports Quick Charging and Always-On Charging for compatible devices that support USB PD (Power Delivery). For wired network connectivity, a separate LAN adapter can be connected to the USB-C™ port.
Usage Features
The manual emphasizes several usage features to enhance the user experience:
- Hot Keys: Users can utilize hot keys for more convenient Windows operation. Details are available in the LG Easy Guide.
- LAN Adapter Connection: To connect to a wired LAN, a LAN adapter (purchased separately) is connected to the USB-C™ port. The USB-C™ port's reversible design simplifies connection.
- Power Connection: The AC adapter is used to power the PC and charge its battery. It's crucial to use only the provided AC adapter. The adapter supports a wide voltage range (100 V to 240 V). The power lamp indicates the charging status: solid on when charging is complete, blinking when charging, and off when the adapter is disconnected.
- System Shutdown/Power Off: The system can be shut down via the Start menu by pressing the [Windows key] or [Ctrl] + [ESC], then selecting "Shut down" from the Power button menu. It's important to allow the system to fully load before shutting down to prevent improper shutdown.
- Touchpad Functionality: The touchpad can be managed through the LG Smart Assistant, where users can enable/disable it or set it to auto-disable when a mouse is connected.
- Wireless Network Connectivity: The notebook supports wireless networks. Users can toggle airplane mode and check Wi-Fi status using [Fn] + [F6] and the Wi-Fi icon on the taskbar.
- Driver Reinstallation: Drivers can be reinstalled by first removing them via Settings > Apps > Apps & features (or Installed apps), then using the LG Update application to install required or updated drivers.
- Reader Mode: This feature adjusts the brightness and color of the LCD screen to mimic printed paper, reducing eyestrain. It can be toggled on/off via LG Smart Assistant > Display Setting > Reader Mode.
- Battery Life Extension: The LG Smart Assistant includes an "Extend Battery Life" function that limits the battery charge to 80% of its maximum capacity, which can prolong the battery's lifespan.
Maintenance Features
The manual provides several guidelines for maintaining the device and ensuring its longevity and safe operation:
- Cleaning: When cleaning the product, users should use a cleaning agent specifically designed for PCs. Thinner, benzene, alcohol, or similar agents should be avoided as they can damage or deform the product.
- Data Backup: Due to the risk of data loss from SSD malfunctions, users are strongly advised to back up all critical data to external storage devices (e.g., USB HDD, memory card).
- Battery Handling:
- Only use batteries certified and acknowledged by LG Electronics Inc. Using uncertified batteries can lead to explosions or fire.
- Keep the battery away from heat sources to prevent explosions or fire.
- Avoid humidity and temperatures above 140 °F (e.g., in cars or saunas) to prevent explosions or fire.
- If battery leakage or a bad odor is detected, contact the local service center.
- Charge the battery only with the provided charger to avoid damage or fire risks.
- Do not allow the battery to come into contact with metallic objects (e.g., car ignition keys, paper clips) to prevent damage, fire, or overheating.
- The product has a built-in battery pack that should be fully charged before first use.
- The battery is a consumable item and its capacity will decrease over time.
- The internal battery cannot be arbitrarily removed or replaced by the user; doing so may void the warranty. Battery removal or replacement should be done by a designated service center, which may incur a fee.
- If the PC is not used for an extended period, keeping the battery level at approximately 50% can increase its lifespan.
- To increase battery lifespan, it's recommended to use the battery for a while before fully recharging it, rather than keeping it constantly at 100% charge.
- Power Cable Care: Do not bend the power cable connected to the AC adapter excessively, as this can break internal wires, leading to electric shock or fire.
- Ventilation: Do not use the product on soft surfaces like carpets, blankets, or beds, and do not place the adapter under a blanket, as this can cause overheating, malfunction, fire, or burns. Avoid leaving the powered-on product in poorly ventilated spaces (e.g., bags) for extended periods to prevent overheating and fire.
- System Reset: If the system stops responding or doesn't shut down properly, the adapter can be removed, and the power button held for approximately 6 seconds to reset the system. However, this may result in unsaved data loss and potential damage to the hard disk or system errors.
- Troubleshooting: The manual includes a troubleshooting section to address common issues like screen display problems, power-on failures, touchpad malfunctions, wireless network connectivity issues, and error messages. It suggests checking settings, reinstalling drivers, and contacting customer service if necessary.
- Windows Functions: Some Windows functions may not be supported depending on the product specifications, requiring separate hardware, drivers, or software. BIOS updates may also be necessary. Windows Auto Update is always active, which may incur internet usage fees and additional system requirements.
- LG Software Installation: UWP apps from LG Electronics can only be installed via the Microsoft Store.
- Virus/Malicious Code: If error messages appear, check the system for viruses or malicious code.
