Which processor does this model use?
AMD Ryzen 7 H255. 8 cores / 16 threads. Integrated graphics: AMD Radeon 780M.
What memory does it use, and can I replace it?
This H255 version has fixed 24GB LPDDR5 onboard. It does not have replaceable RAM sticks. A No SSD configuration still includes the full 24GB memory.
What storage can I install?
2 M.2 2280 NVMe SSD slots. Check the SSD interface and physical size before installation. A slot count describes expansion capacity, not the number of drives supplied.
What wired network and display connections are available?
2 × 2.5GbE ports. HDMI + DisplayPort + USB4 USB-C. Match the cable, display and network equipment to the selected connection.
Which configurations are listed?
H255 / LPDDR5 24GB / No SSD; H255 / LPDDR5 24GB / 1TB SSD. See the selected configuration for its price and availability; unconfirmed configurations cannot be ordered. Configuration names do not imply an operating-system licence or unlisted accessories.
How do I choose an MCIO expansion accessory?
Match the accessory to this H255 model and its board revision. Connector compatibility alone does not establish PCIe bandwidth or graphics-card compatibility; those details need confirmation.
