175 W is the highest total graphics power Lenovo allows in this model; going above NVIDIA’s 60–150 W base range for the RTX 4080 Laptop GPU relies on Dynamic Boost 2.0. The desktop RTX 4080 is a different product.

Display18-inch Mini LED; 2560 × 1600, 16:10 ASUS16-inch WQXGA (2560 × 1600) IPS, non-touch, 500 nits, anti-glare, 16:10, 1200:1, 100% DCI-P3, 240 Hz; DisplayHDR 400, Dolby Vision, G-SYNC, X-Rite factory calibration

DisplayHDR 400 is VESA’s entry-level HDR tier; it does not require local dimming, so HDR looks less striking than on OLED or Mini LED. 240 Hz and G-SYNC give smooth, tear-free motion in fast games. Lenovo notes that “IPS” may also cover similar panel types such as PLS, ADS and AHVA.

Memory—1 × 16 GB DDR5-5600 SO-DIMM; two slots, dual-channel capable; up to 32 GB in Lenovo’s offering

This configuration ships with a single module, so memory runs single-channel until a matching module is added to the second slot. Lenovo’s 32 GB limit is based on the modules it has tested.

Lenovo
Ports—1 × Thunderbolt 4 / USB4 40 Gbit/s (DisplayPort 1.4), 1 × USB-C 10 Gbit/s (Lenovo PD 140 W, DisplayPort 1.4), 4 × USB-A 5 Gbit/s (one Always On), 1 × HDMI 2.1 (up to 8K/60 Hz), 1 × RJ45 Gigabit Ethernet, 3.5 mm audio

140 W charging over USB-C needs Lenovo’s own adapter; other adapters may deliver less. Up to four independent displays including the internal one are supported; Lenovo lists up to 4K/60 Hz for external outputs. Ethernet is 1 Gbit/s, not 2.5G, and supports Wake-on-LAN.

Audio and camera—HARMAN stereo speakers (2 W × 2, super linear), Nahimic Audio, smart amplifier; dual microphones; FHD 1080p camera with electronic shutter (E-shutter) Lenovo
Cooling—Hybrid cooling: air cooling + liquid-metal thermal interface

Liquid metal transfers heat between the chip and cooler more efficiently than standard paste, which makes servicing more delicate.

Lenovo
Battery and power—99.9 Wh lithium-ion, Super Rapid Charge; 330 W slim-tip GaN adapter

Lenovo says Super Rapid Charge reaches 30% in 10 minutes, 70% in 30 minutes and 100% in 80 minutes. 99.9 Wh sits just under the usual airline battery limit. Lenovo quotes 10.4 hours of 1080p video playback at 150 nits.
