IP rating/processor/memory/battery/interfaces come from the manufacturer datasheet DURABOOK_DM_S15_EN_20251202.pdf. Display size, resolution, MIL-STD, brightness, weight, operating temperature and configurability unchanged from comparison table: laptops (German) (checked against the manufacturer datasheet, no deviation).

Configuration options
The S15 is one of three Durabook laptops with an interactive configurator. Configurable groups: RAM, data storage, display (display selection), communication, power supply/batteries, warranty (extended/accidental damage/battery), docking/vehicle solutions. Individual selection values and prices are only available in the configurator on the product page, not here.
Data notes:
- Corrected: The IP rating was previously „IP5X“ without qualification. The manufacturer datasheet states „IP 53 certified (optional)“ – the rating is therefore optional equipment, not standard.
- Corrected: Thunderbolt 4 was previously missing entirely from the interfaces list. The manufacturer datasheet lists „Thunderbolt 4 x 1“ as standard equipment.
- Known data contradiction (not resolved): The accessory for charging the battery is called „Battery Charger – 2 Days“ in the product page's configurator, and „Battery Charger – 2 Bays“ in the equipment list on the same page (part number
DC2S5_). Both names come from /en/laptops/durabook-s15; which one is correct can only be clarified by the client. The manufacturer datasheet does not name this accessory.
