Lenovo ThinkPad T480

Why it’s here

The T480 is where the classic ThinkPad formula made its last full appearance: two SODIMM slots, a socketed 2.5" bay, a hot-swappable external battery bridging an internal one, and a hardware maintenance manual Lenovo publishes as if repair were a normal thing owners do — because on this machine it is. After 2018 the T-series started soldering memory and slimming away options. The T480 is the checkpoint the repair community keeps recommending, years after its warranty cards expired.

The story

The T-series is the direct descendant of the IBM ThinkPad line Lenovo acquired in 2005, and the T480 (introduced January 2018) closed out its most repair-friendly era. It was built for corporate fleets: tens of thousands at a time, leased for three to five years, maintained by in-house technicians using Lenovo’s own published service documentation — which is precisely why the used market is now flooded with cheap, well-documented, parts-compatible machines.

The repair community canonized it in hindsight. Its successor, the T490, soldered half the RAM and slimmed the battery system; each generation after gave up a little more. What was ordinary in 2018 — a business laptop you could completely disassemble with one screwdriver — reads as remarkable now, and iFixit’s T480 hub keeps growing years after production ended.

Durability report

The chassis is glass-fiber-reinforced plastic over a magnesium structure — not luxurious, but proven across millions of corporate units that spent five years being dropped into rolling bags before reaching the used market. Hinges and keyboards, the classic laptop failure points, are both cheap modules here. The real durability question is electronic: 8th-generation Intel firmware support has wound down, and software rot — the quiet killer in this category — will eventually define this machine’s lifespan. The mitigation is that ThinkPads are Linux’s home turf, and a T480 running a current distribution sidesteps most of the obsolescence schedule.

Repair & parts reality

Nearly perfect. The maintenance manual documents every part with removal steps; iFixit hosts twenty replacement guides for the rest; and the corporate off-lease flood means batteries, keyboards, palmrests, and whole donor machines are commodity items. The PowerBridge design lets you replace the external battery without even shutting down. Deductions are for the modern-era compromises: soldered CPU, and a USB-C charging port that lives on the mainboard rather than a cheap daughterboard — the one repair that isn’t a shrug.

The long-term math

$250 used, plus perhaps $60 in batteries and $40 in opportunistic parts over five further years, is about $70 a year for a completely serviceable computer. The math only fails when the software world moves on — which is why the longevity score, not the repairability score, is the one holding it back.
