The laptop supports a Linux-compatible option, and effort was expended specifically to disable that option. If some hardware isn't supported by Linux drivers, that's understandable. If software is added to restrict the modes that the hardware is allowed to operate in, and the restriction wasn't disclosed at the time of sale, I'll return the hardware, because the product doesn't match what I thought I was buying. If I buy some hardware, I've done research on whether all of its chipsets and devices have Linux driver support just as a matter of course, because I don't expect that Linux will run on every PC. But I feel like I have a right to know if a company puts a non-standard artificial restriction on their hardware. Apparently in this case, Windows 10 doesn't even have the driver included by default, so I can't even reload the software that the machine was designed to run, on my own. That sounds like a defect in the product, to me.

They deny purposefully disabling Linux, and I don't have any evidence against that denial. They don't deny disabling AHCI, because they clearly did. In the disassembly of the code: https://lnv.i.lithium.com/t5/image/serverpage/image-id/76843i7CD81FDBF9327A32/image-size/large?v=v2&px=999 https://lnv.i.lithium.com/t5/image/serverpage/image-id/76843... Intel's RAID is implemented in their driver. Switching the option from AHCI to RAID switches the disk controller's ID so it doesn't bind to the OS's standard driver (whichever OS that is), and binds to Intel's instead (assuming it's present). Intel provides its driver (and only for Windows), Lenovo locks the option so that hapless users mucking about in the UEFI settings don't make their machines unbootable. Lenovo can deny "deliberately blocking Linux", but they can't deny "practically blocking Linux".
