Lenovo ThinkPad X1 Yoga (4th Gen) 20QF — Intel Core i7-8665U up to 4.8 GHz vPro, UHD Graphics, 16 GB, 1 TB SSD TCG Opal Encryption 2 NVMe, 14" 3840 x 2160 IPS Touch, Win 10 Pro, Wi‑Fi 5, Iron Gray, US Kbd

Designed for travel and daily use: the X1 Yoga Gen 4 is a 2-in-1 with an aluminum chassis that’s 17% smaller than the previous generation and weighs just 2.99 lb / 1.35 kg. It delivers up to 18 hours of battery life*, and when you need a fast top-up, Rapid Charge restores the battery to 80% in 60 minutes—providing approximately 14.4 more hours of run time based on MobileMark 2014 testing.* (Actual battery life varies by settings, usage, and other factors.) Performance and storage: equipped with 8th Gen Intel Core processors (Intel Core i7-8665U up to 4.8 GHz, vPro) and ample memory for demanding tasks. The PCIe NVMe solid-state drive offers responsive, high-speed storage—this configuration includes a 1 TB SSD with TCG Opal Encryption 2. Built-in pen for creativity: the rechargeable ThinkPad Pen Pro is stored and charges inside the laptop’s garaged slot so you can sketch, sign, and take notes without worrying about batteries or misplacing the pen. Brilliant display options: choose the optional 14" 3840 x 2160 Ultra HD (4K) IPS touchscreen with High Dynamic Range (HDR) and Dolby Vision for more vivid colors, greater contrast, and improved detail. Alternatively, an FHD panel with PrivacyGuard is available if screen privacy is a priority. Immersive audio and voice: the Dolby Atmos speaker system combines two up-firing speakers near the keyboard with two down-firing woofers beneath the chassis for richer, more enveloping sound. Four 360-degree microphones reduce background noise on calls and capture voice from across the room, enabling voice-activated features such as wake and media control. Rugged reliability: like other ThinkPads, this model undergoes testing against 12 military-grade requirements and more than 200 quality checks to ensure reliable operation in harsh environments—from extreme cold to dust, drops, and spills. Connectivity options: when Wi‑Fi isn’t available, an optional LTE-A card with WWAN lets you connect over cellular networks—note that WWAN must be configured at the time of purchase and cannot be added later. Security and privacy: ThinkShield protections include a discrete Trusted Platform Module (dTPM) for hardware encryption, a physical ThinkShutter camera cover, and a fingerprint reader for biometric login. PrivacyGuard is an integrated electronic privacy filter that limits viewing angles, and PrivacyAlert—software that works with the IR camera to warn you if someone is peeking over your shoulder—requires the optional IR camera. *Battery life and Rapid Charge claims based on MobileMark 2014.
