Overview
The LG Gram 15Z90N focuses on mobility for users who travel often and still want a full-size 15.6-inch screen. The main advantage is low weight for this class: 1.12 kg. It uses Intel Core i7-1065G7, integrated Iris Plus Graphics G7, 16 GB of memory, and 1 TB SSD storage. In daily use, it targets office work, web tasks, video calls, and media playback rather than heavy graphics workloads.

Design and Portability
The magnesium-alloy body helps keep weight very low for a 15.6-inch model. The chassis is described as rigid in normal handling, with matte surfaces that do not highlight fingerprints much. The style is restrained and office-friendly, while the hinge keeps the display stable in typical use positions.
Display, Audio, and Webcam
The Full HD IPS panel provides wide viewing angles and convincing color for everyday work. Because the panel is glossy, reflections are noticeable under bright indoor lighting. The speakers are usable but limited in low-end depth, so headphones improve media and call quality. The 720p webcam is acceptable for meetings but image quality drops in weaker artificial light.
Keyboard and Input
The keyboard includes a numeric keypad and a backlight, which is useful for spreadsheet-heavy workflows. Key travel and feedback are described as comfortable for long typing sessions. The power button integrates a fingerprint reader, and the touchpad supports standard multi-touch gestures with consistent responsiveness.
Performance and Thermals
With Core i7-1065G7 and Iris Plus Graphics G7, the laptop is best suited to productivity tasks, browser multitasking, streaming, and light games. The configuration in this review includes 16 GB RAM and two 512 GB SSD drives (1 TB total). Cooling is generally quiet, but the underside can become warm under sustained load.
Ports and Battery Life
Connectivity is practical for office use: USB-A ports on both sides, HDMI, Thunderbolt 3 via USB-C, microSD, and a combo audio jack. Wireless support includes Wi-Fi 6 and Bluetooth 5.0. Battery life is a clear strength, with around 10 hours reported for web browsing and similar video playback time in light workloads.
Verdict
The LG Gram 15Z90N is a mobility-first 15.6-inch laptop. Its strongest points are very low weight, solid everyday usability, and long battery life. The main compromises are average speaker quality, reflective glossy display behavior, and noticeable heat at the bottom during heavier tasks. For users who prioritize portability and all-day work away from a charger, it remains a practical option.
