Compatibility & Software Support
Operating System
Windows 11 Pro on Arm, as a Copilot+ PC. Arm-native and most standard Windows applications run, but check that specialised drivers, VPN clients and security agents your organisation relies on support Windows on Arm before deploying.
Docks & Displays
Two USB4 40 Gbps Type-C ports with DisplayPort Alt Mode and Power Delivery work with USB-C docks and monitors, for up to three external displays. There is no built-in HDMI or Ethernet port, so use a dock or adapter for wired networking. Dell advises against connecting both cables of a dual-cable dock to both Type-C ports at once.
Upgrades
Memory is soldered to the system board and cannot be upgraded, so choose the capacity you need at purchase. Storage uses a single M.2 2230 PCIe Gen4 NVMe slot (Dell offers up to 1TB).
