Does this laptop have Intel Managment Engine?

That laptop has an Intel Kaby Lake generation CPU, which does have the Intel Management Engine.

Lenovo was apparently using the Intel 9260 802.11AC wifi card for those laptops. That network card is not supported with Trisquel. You would need to see if you could replace it with an Atheros card, or you would need to use an Atheros wifi USB dongle instead.

Unless boot guard is a blocker. Lenovo computers are mostly blocked by boot guard from being corebooted from gen 4+ if I recall.

However, there is a boot guard vulnerability that could be exploited potentially maybe to put coreboot on. I am not sure how likely it is, but I recall reading about it here:

https://support.lenovo.com/us/en/solutions/ps500187-bios-modules-unprotected-by-intel-boot-guard-vulnerable-to-physical-attack

Its beyond me whether this is possible or not to coreboot the ones vulnerable.

But it could be hope for the future. :)

NovaCustom is selling laptops right now with Intel 12th generation chips with Dasharo coreboot and with the HAP bit set to disable IME. They said they should be selling laptops by this summer 2024 with 14th generation Intel chips with Dasharo coreboot.

System76 is currently selling laptops with 13th generation Intel chips with coreboot with the HECI method of "soft" disabling IME. They don't appear to use Dasharo coreboot, but a coreboot of their own configuration, based on what information I've been able to gather without actually using one of their laptops.

Both NovaCustom and System76 are adapting laptops made by the Clevo manufacturer from Taiwan. NovaCustom appears to be an officially supported hardware vendor of the Dasharo coreboot project. Possibly the Dasharo coreboot project focuses on those Clevo laptops, and maybe they are easier to support with coreboot for some reason.
