Lenovo 100-15IBY review

Lenovo 100-15IBY — the floor of the catalog, priced accordingly

The 100-15IBY was Lenovo's cheapest possible 15-inch laptop: a dual-core Celeron N2840, integrated graphics only, and not much else. Today it asks $108 against a $248 general-class median. Its scores read as zero across the board — performance index 0 versus a 43 median, graphics 0 versus 27, composite 6 versus 53 — which is the measurement floor speaking: the N2840 sits below every threshold the pipeline scores. Those zeros mean "slowest tier in the catalog," and they are honest.

What it can still do

The N2840 was weak when new in 2014 — a 2.16 GHz Burst dual-core designed for Chromebook-class workloads. With patience it runs a browser with a few tabs, a word processor, and video playback. Anything compiled, rendered, or multi-threaded will not be a good experience. There is no gaming conversation to have: the iGPU of this era does not clear any modern bar.

The trade-offs, stated plainly

At $108 the 100-15IBY competes with used machines one or two silicon generations above it. Its only real argument is condition and completeness — a working screen, keyboard, and chassis for the price of a keyboard. The composite score of 6 against a 53 median tells the value story: you are not buying capability, you are buying presence.

Price trajectory

No depreciation curve is computed for this model — without a usable launch-price anchor there is no honest forward projection. What can be said: at $108 the machine is already at terminal value, the price band where further decline is measured in single-digit dollars.

Against its neighbors

Neighbors cluster tightly: an HP Pavilion G6-1070SO at $122 and an HP 15-ay087ur at $120 above; a Compaq CQ57 at $98 and an HP 15-ra047ur at $101 below; a Lenovo G580 at $108 dead sideways. Several of those carry real dual- and quad-core CPUs from better lineages — the G580 in particular is a same-price machine with a stronger processor, worth preferring.

Bottom line

The 100-15IBY is the honest floor: $108 for the slowest mainstream x86 class in the catalog. It fits a buyer who needs one working laptop for the lightest duties and nothing more. For everyone else — including gamers, students with heavier workloads, and anyone keeping it beyond a couple of years — the same money buys measurably more machine elsewhere in this very price band.
