Hello,

I am considering purchasing a Tuxedo InfinityBook Pro 15 - Gen10 (AMD variant) and have a few questions. This is the first time I'm seriously considering a Tuxedo/non-mainstream brand like HP/Dell so have lots of doubts but excited about the prospect of finally not having to fiddle with things to get them to work on Linux. I've also spent some time reading few of the older posts which has already answered several questions.

The reason I'm considering AMD over Intel is mainly the processor, as I can get the higher tier on AMD (one of the AI 9 variants), though at a loss of certainty of Thunderbolt 4's guarantee of performance and the lack of WiFi 7 which I'm keen on having.

General

1. For the AMD variant: any real-world performance/thermal difference between the Ryzen AI 9 365 and HX 370 in this specific chassis, given both share the same cooling?
2. Are the batteries proprietary to Tuxedo? Can also be purchased from an independent vendor/retailer?
3. Does this model use open coreboot firmware or something proprietary?
4. For long-term users of Tuxedo laptops in general, how long do these tend to last? My HP Elitebook/Probook laptops tend to last well over 5 years (usually only requiring a battery replacement and RAM upgrade).

Wi-Fi

1. Does it use a standard, unrestricted M.2 2230 E-key slot for Wi-Fi, or is it locked to specific certified modules?
2. Does swapping the Wi-Fi card myself (e.g. to a MediaTek MT7925 or MT7927) void or affect the warranty? Will adding one of these cards enable WiFi 7 and maintain 6 GHz on AMD variant with Linux? Based on what I've read so far, it seems that neither WiFi 7 not 6 GHz are going to work with the AMD + Linux combination.
3. Are such WiFi modules even easy to procure as an individual (assuming support lands at some point)? I've searched for the Mediatek models and can't find them on any of the typical UK retailers like Box.co.uk, Overclockers.co.uk, CCL, Scan etc. Amazon has a few listings but they appear generic models using the Mediatek models from unknown sellers, not Amazon themselves.
4. On the AMD variant FAQ, there is a mention of MediaTek as an “alternative with its own limitations”. Does anyone know what exactly are those limitations?
5. Is there a firmware/BIOS allowlist that could block a non-original Wi-Fi card from being recognized?

Known issues

1. Is the Motorcomm YT6801 LAN driver manual installation still required if not using Tuxedo OS? If using Ubuntu 26.04 which ships with Kernel 7, is it already included? I tend to stay on the latest Ubuntu version (not LTS) and from the sound of it, the official WebFAI method only supports LTS so wondering if I'll still have access to the drivers.
2. Are there any other disclosed hardware quirks not listed on the FAQ page?

Dual-boot & encryption

1. What breaks when combining full-disk encryption with a dual-boot Windows+Linux setup — is it a hard incompatibility, or a supported-but-untested configuration?
2. If I want encryption, is single-OS (Linux only, no Windows) the only supported path even if I'm willing to install/re-install both myself?
3. Custom partitioning isn't supported, but there is a page describing how to install Windows then Linux. Does this impact warranty/support in any way if I do it myself?
4. If I don't like Tuxedo OS after trying it, can I install standard Ubuntu (non-LTS) instead without impacting warranty/support?

Warranty & support

1. For a UK customer, what's the typical round-trip time for a repair shipped to Germany, and who covers that shipping cost? It sounds like outside the EU customer has to pay for shipping but wondering if there are any real examples where people have had to do it.
2. Is there any statutory or otherwise return window (like within 30 days of delivery) if one doesn't like the product? My main concern is with the touchpad and keyboard on which there are a lot of mixed opinions. Additionally, audio and webcam seem to be rated consistently bad but wondering again if it will be bad enough to make me want to return it.
3. The warranty link only shows an old document from 2014 in German. Does anyone have a current English version of this document? I can't seem to find it on the website.

Many thanks for taking the time to read and respond!
