Just to confirm, that's this system: https://www.lenovo.com/us/en/laptops/thinkpad/thinkpad-l/ThinkPad-L490/p/22TP2TBL490 We could ask if lenovo will give us one, but if not we could pull a Jens. [the backstory is that when Jens was doing queueing in the block layer, there were lots of SATA devices that didn't work quite right but you couldn't tell unless you actually tried them out. Getting manufacturers to send samples is rather arduous, so he took to ordering them online, testing them out, and then returning them for a full refund within the allowed window] It looks like Lenovo has a nice christmas returns policy: https://www.lenovo.com/us/en/shopping-faq/#returns James
