The Lenovo ThinkPad X390 is a compact business laptop whose specification is built around mobility, practical connectivity and sustained working potential. At 1.22kg, it has a strong portability case, while its 13.3-inch IPS display keeps the overall format focused on carrying convenience rather than a large desktop workspace. The 1920x1080 resolution gives the panel a clear Full HD foundation for standard Windows productivity.
Built for mobile work
The processor is an Intel Core i5-10210U from Intel’s 10th Generation Core family, supported here by 8GB of RAM. That combination establishes a sensible platform for general professional computing on paper, although the memory capacity is relatively modest for users who regularly keep numerous demanding applications or large working sets open simultaneously. The machine runs Windows 10 Pro 64, placing it firmly in a conventional business-computing environment.
Storage is one of the more convincing parts of the specification. A 512GB M.2 2280 PCIe NVMe SSD offers meaningful capacity for documents, applications and locally stored work, while the NVMe interface is designed for fast storage access. The specification therefore balances a compact chassis with storage that should feel appropriately substantial for a productivity-focused machine.
Connectivity is unusually central to the X390’s appeal. Its ports include two USB 3.1 Gen 1 connections, one with Always On functionality, alongside USB-C 3.1 Gen 2 with Thunderbolt 3, a further USB-C 3.1 Gen 1 port, HDMI 1.4b, an Ethernet extension connector, a combined headphone and microphone jack, and a side docking connector. That spread should accommodate a range of desk accessories, displays and wired networking arrangements without making the laptop dependent on a single connection type. Wireless networking is covered by dual-band 802.11ac Wi-Fi and Bluetooth 5.1.
Clear trade-offs
The display’s 13.3-inch size reinforces the portable design but leaves less physical screen area for side-by-side work than a larger-format laptop would provide. The 8GB memory allocation is another defined constraint, particularly for users whose workloads extend beyond straightforward office and browser tasks. Graphics are handled by integrated Intel UHD Graphics, so the hardware is positioned around standard productivity rather than a discrete-graphics configuration.
Battery capacity is listed at 48Wh, with a manufacturer-rated battery life of 17.6 hours. That rated figure gives the X390 impressive endurance potential on paper, though it remains a specification-based estimate rather than a guarantee of every working pattern. The carbon-fibre or PPS top and magnesium-aluminium bottom also give the design a clearly specified mixed-material construction.
