Manufacturer warranty (source market)iThe maker's warranty period for the exact SKU or configuration and market named in the source note. It applies only to that stated market, not every regional variant. Statutory consumer rights are excluded. The base term is stored. An extension that needs registration goes in the source note.

www.bee-link.com/products/beelink-ser9-pro-amd-ryzen-7-h-2551Maker product pagebee-link.com/products/beelink-ser9-pro-amd-ryzen-7-h-255Read 10 October 2026Exact current Shopify variant 47701525790962 is H 255, 32 GB soldered LPDDR5X-6400, 1 TB SSD, Frost Silver and UK adapter. It differs from the existing HX 370 / Radeon 890M model, the speakerless SER9, SER9 MAX, 24 GB references and OpenClaw versions. Maker selected SKU contains a localized colour / plug suffix, not a separately published physical hardware model number, so no invented English model code is stored.

Options are U9-285H 32 GB RAM + 1 TB SSD and U9-285H 32 GB RAM + 2 TB SSD. This file describes the 32 GB and 1 TB option. The page text is partly copied from the maker's GT2 Mega page, so conflicting lines are checked against the photos, the UK page and the support page.
