Refurbished Lenovo ThinkPad X280 — The Lightest X-Series with Thunderbolt 3
The refurbished Lenovo ThinkPad X280 is the most advanced X-series ThinkPad in our catalogue — bringing 8th Generation quad-core performance, Thunderbolt 3 and a redesigned chassis down to just 1.13kg. The X280 made two significant advances over the X270 it replaced: the proprietary charging port was dropped entirely in favour of USB-C charging, and it gained a dedicated Thunderbolt 3 port alongside a standard USB 3.1 Type-C port. Tested against 12 MIL-SPEC requirements and passing over 200 durability tests, the X280 is the definitive modern ultraportable business ThinkPad. Powered by an Intel Core i5-8250U 8th Generation quad-core processor, 8GB DDR4 RAM and a 256GB SSD, the refurbished Lenovo ThinkPad X280 is a fast, feature-rich machine at an outstanding price.

Thunderbolt 3 — 40Gbps and Dual 4K Display
The X280 includes a dedicated Thunderbolt 3 port — the fastest connection available on a laptop. Thunderbolt 3 delivers 40Gbps data transfer, can drive two 4K displays simultaneously from a single port, supports external GPU enclosures and is compatible with Lenovo’s USB-C docking stations. Alongside it sits a standard USB 3.1 Gen 1 Type-C port that supports charging, DisplayPort output and data transfer. Both USB-C ports can be used to charge the X280. According to NotebookCheck’s independent review, the X280 earns strong ratings for portability, keyboard quality and overall build.
8th Gen Quad-Core — A Genuine Step Up
The Intel Core i5-8250U is a quad-core 8th Generation processor — a significant improvement over the dual-core 6th and 7th Generation chips in the X260 and X270. Tasks that use multiple CPU cores — video calls while running applications, data processing, compilation, heavy multitasking — benefit noticeably from the additional cores. The 256GB PCIe NVMe SSD is also faster than the SATA SSDs in older X-series models, contributing to a noticeably quicker everyday experience.
1.13kg — The Lightest X-Series
The X280 redesigned chassis weighs just 1.13kg — 13% lighter than the X270 and the lightest ThinkPad X-series laptop available. At 17.4mm thin it is also 15% slimmer than its predecessor. For daily commuters and frequent travellers, the X280 is the most comfortable X-series ThinkPad to carry.
Important: Ethernet Requires a Dongle
Unlike older ThinkPads, the X280 dropped the standard RJ-45 Ethernet port in favour of a proprietary mini Ethernet connector. A Lenovo Ethernet Extension Adapter (sold separately) is required for wired network connections. This is worth noting if wired Ethernet is essential to your setup. Wi-Fi 802.11ac is built in and works without any adapter.

Frequently Asked Questions
Does the X280 have standard Ethernet? No — it requires a Lenovo proprietary Ethernet adapter dongle (sold separately). Wi-Fi 802.11ac is built in and works without any adapter.
Is the RAM upgradeable? No — the X280’s RAM is soldered to the motherboard. The 8GB configuration cannot be expanded. This is a departure from older ThinkPads where RAM was easily upgraded.
What is the difference between the two USB-C ports? One is Thunderbolt 3 (40Gbps, dual 4K display support, external GPU). The other is USB 3.1 Gen 1 (5Gbps, DisplayPort, charging). Both can charge the laptop.
How does it compare to the X270? The X280 is lighter (1.13kg vs 1.27kg+), adds Thunderbolt 3, gains a quad-core processor and drops the proprietary charging port. It trades the hot-swappable dual battery of the X270 for a larger single integrated battery. See our ThinkPad X270 for comparison.
