- This is a USA reference configuration (SKU 20AV002KUS), not an Indian retail record or a SPURGE stock claim. Availability, condition, price, GST, delivery and warranty are confirmed in the SPURGE quotation.
- This is a 2013-era, 2.5 kg+ machine — confirm the panel (HD vs FHD), storage and RAM fit the intended workload; an SSD and RAM bump are the common upgrades.
- Confirm the supplied unit’s panel (HD vs FHD), camera, fingerprint reader, wireless module and OS licence.
- The 4 GB reference leaves one SO-DIMM socket free; 16 GB is the documented maximum (lower than the L440 — do not promise 32 GB).
- Request per-unit battery health; the 9-cell 99.9 Wh option has the longest documented runtime.
