Lenovo ThinkBook 14 2-in-1 Gen 4 review

Lenovo ThinkBook 14 2-in-1 Gen 4: the dependable folder that keeps its promises

The ThinkBook 14 2-in-1 Gen 4 asks $1,084 on today's market, and what you are really buying is staying power: a reliability index of 84 against a convertible-class median of 49, a 71 percent edge that places it in the top quarter of its class. Around that core sits a Core Ultra 5 125U with 32GB of memory, a CPU score of 74.25 running comfortably above the class mark of 59.6, and an office index of 76.51 in the high band. This is a machine built to be opened, folded, carried and used every working day for years — not to win benchmark shootouts.

Where it holds up

Longevity is the headline. The reliability reading of 84 is the kind of figure you usually pay flagship money for, and here it arrives at a mid-tier price. Compute holds its own too: the 74.25 CPU score sits in the high band with a top-quarter placing, and 32GB of RAM means the machine will not run out of working memory before you run out of working day. Portability reads 64.1 — mid-band, honest for a 14-inch convertible — and the office score of 76.51 confirms that documents, browsers and calls are exactly what this chassis was drawn for.

Where it falls short

Graphics is the soft spot, and it needs careful reading: the score sheet shows a zero, which is not a measured zero but a coverage gap — the integrated graphics configuration has no matched scoring entry in the database, so treat that line as unmeasured rather than failed. The resolved task axes are more telling: gaming sits at 19, 3D modeling at 19 and engineering CAD at 25, all in the low band, and photo design manages only a mid-band 35. Anyone hoping to render, edit seriously or game on this machine should look elsewhere; the performance index of 41.48 also lands mid-pack rather than near the top. A hands-on check of graphics behavior before committing would be prudent given the unmatched entry.

Price and depreciation

At $1,084 the listing sits in the upper-middle of the convertible shelf. There is no listing history to anchor a depreciation curve for this unit, so the honest number is the class rate: about 13.87 percent a year. Plan on that drain, not on a projection chart, and the price starts to look reasonable against what the reliability figure promises in return.

Alternatives to consider

Within the same family, the Gen 5 of this same machine (model 1799) costs $191 more and shares six of eight axis figures — office, gaming, modeling, CAD, photo and portability all match — while measuring lower on the performance yardstick (32.69 against 41.48) and much lower on value (15.65 against 42). If a stylus-friendly folder matters less than raw endurance, the IdeaPad 5i 2-in-1 14 (model 1829) sits at the same $1,084 with a higher graphics placing but only 16GB of memory.

Bottom line

Fairly priced for the class. The ThinkBook 14 2-in-1 Gen 4 trades graphics firepower for reliability and everyday competence, and for a buyer whose workload lives in browsers and office suites that trade reads as a bargain. For anything visual or computational, the low task bands are a hard ceiling.
