Enso OS checks a used laptop or phone's battery, storage, memory and screen, then turns what it finds into one simple report anyone can trust. No more guessing what "tested and working" actually means.
THE RESEARCH // 01
Studies keep pointing at the same three things: devices last longer than people think, buyers don't trust "refurbished," and that lack of proof is why they lowball every offer to hedge against the risk. Enso OS removes the guesswork, so a verified device can sell for what it's actually worth.
He et al. (2023) report that extending device life can deliver greater environmental benefit than prematurely shredding and remelting recoverable materials.
Enso OS prioritizes measurable life extension and Scope 3 evidence before a device reaches recycling.
Martin (2025) describes refurbished devices as a perceived gamble. Boddington (2016) and Zoka & Korez Vide (2025) identify quality doubt and stigma as barriers to circular adoption.
Subjective labels are replaced with disclosed technician test records covering the components buyers actually depend on.
Using behavioral field-study principles described by Serdikoff (2021), observations were conducted during Portugal’s back-to-school purchasing period at a refurbishment facility.
In the observed trial, detailed RAM, disk, LCD, keyboard and battery checklists increased trust and removed rejection of cosmetically worn Grade B devices within the study sample.
The product separates visible wear from verified function, while preserving the underlying evidence.
The European Commission’s 2025 circular-economy direction supports durable, repairable products and Digital Product Passports. Electronics timelines remain category-specific.
Enso OS structures bench results into a portable DPP-ready record without claiming that all used electronics require a passport today.
HOW IT CHECKS YOUR DEVICE // 02
The software talks to the hardware directly and reports back exactly what it finds. It checks. It doesn't repair, unlock, or bypass anything.
Runtime capacity against design mWh, charge-controller stability, cycle degradation and voltage decay under controlled load steps.
DESIGN_MWH · CURRENT_MWH · HEALTH_RATIO
S.M.A.R.T. parsing, bad-sector detection, endurance data and NVMe/SATA integrity checks.
SMART_STATUS · BAD_SECTORS · LIFE_%
Address-level RAM stress testing under dynamic workloads before the device is prepared for resale.
RAM_RANGE · ERROR_COUNT · PASS_RATE
LCD panel verification, keyboard matrix mapping and I/O communication records.
PANEL · KEY_MATRIX · IO_BUS
Exterior grade A+ to B is stored separately from internal health so scratches do not obscure validated function.
COSMETIC_GRADE ≠ FUNCTIONAL_STATUS
STRUCTURED OUTPUT // 03
This isn't the EU's Digital Product Passport. That one (once it covers electronics) tells you what a device is made of and how repairable it was designed to be. Ours tells you something different: whether this specific used unit was actually tested, and whether it works. Other diagnostic tools exist too, but they're typically built for the business handling the device internally. Enso OS is built to reach the buyer and seller directly, so both sides see the same record, ready to attach to a listing or keep for your files. What's below is an example, not live data.
A laptop built around an AMD Ryzen 9 5900HS processor, tested and issued this passport at Enso's Santo Tirso facility. Every field below reflects a hardware check run on the unit itself, not a spec sheet or a seller's own claim.
SOURCES // 04
The research behind everything above. We keep what we observed ourselves separate from peer-reviewed literature, so you can tell the difference.
PILOT INTAKE // 05
We're looking for refurbishers, ITADs, and marketplaces to pilot this with, and individual buyers and sellers can use it too, free for your first two device checks. Tell us a bit about your setup and we'll get back to you.
