Lenovo IdeaPad 100-15IBY review

Lenovo IdeaPad 100-15IBY — Bay Trail Celeron at the floor

The IdeaPad 100-15IBY is a mid-2010s budget 15-inch built on Intel's Celeron N2840 — a Bay Trail dual-core SoC designed for the cheapest Windows laptops sold new. At $129 it sits 48% below the general-laptop median of $248. The measured profile: graphics 0, performance index 0 against a 43 median, LB score 6 — the standard floor-tier reading for this silicon generation.

What a Bay Trail Celeron is

Two efficiency cores at up to 2.58 GHz on a phone-class architecture adapted for laptops: adequate in 2015 for one browser window and a video player, below modern tolerance in every dimension. The performance index of 0 is the honest figure. The IdeaPad 100 line was Lenovo's floor family — the machine sold on price alone, and the silicon reflects it.

No hidden upside

Performance 0, graphics 0, LB 6 (−88.7% versus class): the categorical picture. The honest role is single-application terminal duty, offline media, or controlled-environment use. The band around this price is dense with similar floor-tier machines and a few faster platforms at the same money — the buyer's task is picking the faster one, which this listing is not.

Price framing

No reliable depreciation data is on record for this model (no original MSRP or release year), so no forward projection can be computed. The $129 asking price is terminal value — no resale expectation, no upgrade path worth funding.

Where it sits against peers

Pricier neighbors are the HP 17-p023ng ($137) and Pavilion G7 ($145); cheaper options are the Pavilion G6-1070SO ($122) and 15-ay087ur ($120). The sideways Inspiron 15 3542 ($123) is a faster platform for less money — the comparison that closes this listing's case.

Bottom line

A floor-tier Bay Trail machine: performance absolute floor, neighbors faster on every side. Recommended only where price is the sole criterion — the Inspiron 15 3542 at $123 delivers more machine for six dollars less.
