Lenovo ThinkPad X1 Yoga (4th Gen) 20QF — 14" UHD 4K Touch — Intel Core i7-8665U (up to 4.8 GHz) vPro — 16 GB RAM — 512 GB NVMe SSD (TCG Opal 2) — Win 10 Pro — Iron Gray — US Keyboard

Portable power and long run-time: The X1 Yoga Gen 4 is built in a lighter aluminum chassis that is 17% smaller than the previous model and weighs just 2.99lb / 1.35kg. Its battery can last up to 18 hours on a single charge (based on MobileMark 2014 testing). When you need a quick top-up, Rapid Charge restores the battery to 80% in 60 minutes, providing an additional 14.4 hours of use. Battery life will vary with settings, usage, and other factors. Performance and storage: Equipped with 8th Gen Intel Core processors and ample memory, this convertible delivers responsive everyday performance. The PCIe NVMe solid-state drive offers fast boot and app load times while maintaining the included 512 GB capacity and TCG Opal 2 encryption. Included active pen: A rechargeable ThinkPad Pen Pro is integrated and charges while stowed in its garaged slot—no ink, no disposable batteries, and less chance of losing it. Use it to sketch, take notes, or sign documents. Stunning display options: Choose the optional 14" 4K HDR (3840 x 2160) touchscreen with Dolby Vision for vivid color, higher contrast, and greater brightness for media, video calls, and creative work. There is also an FHD panel available with PrivacyGuard for enhanced on-screen privacy. Immersive audio and voice: The Dolby Atmos speaker system pairs two up-firing speakers near the keyboard with two down-firing woofers underneath for a fuller soundstage. Four 360-degree microphones reduce background noise on calls and pick up voice from across the room, enabling voice activation features. Rugged reliability: Like other ThinkPads, the X1 Yoga Gen 4 undergoes more than 200 quality checks and testing against 12 military-grade requirements to ensure it survives harsh environments—from extreme cold to sandy, dusty conditions and accidental drops or spills. Always connected options: For connectivity away from Wi-Fi, an optional LTE-A WWAN card lets the laptop connect using cellular networks much like a smartphone. Note: WWAN must be configured at time of purchase and is not upgradeable later. Comprehensive security: The system includes ThinkShield protections— a discrete Trusted Platform Module (dTPM) for hardware encryption that works with Windows 10 security, a ThinkShutter physical camera cover, and a fingerprint reader for biometric sign-in. PrivacyGuard is an integrated electronic privacy filter that limits viewing angles so only someone directly in front of the screen sees the content. PrivacyAlert software, which works with the IR camera to warn you when someone is looking over your shoulder, requires the optional IR camera.
