Confirm the laptop. Then confirm the terms.
- This is a USA reference configuration (SKU 20HB001JUS), not an Indian retail record or a SPURGE stock claim. Availability, condition, price, GST, delivery and warranty are confirmed in the SPURGE quotation.
- Confirm the supplied unit’s panel (4K vs FHD, touch option), GPU (Quadro M520), both batteries and their health, keyboard layout and OS licence.
- The 8 GB reference leaves one SO-DIMM socket free; 32 GB total is the documented maximum.
- Storage is either/or: a unit with a 2.5-inch drive has no M.2 slot in use, and vice versa.
- This is a 2017-era platform — plan deployment length accordingly.
- Share quantity, workload, city and required date so SPURGE can confirm supply and quote rental or purchase terms.
