This article outlines the various anti-consumer measures used in the Lenovo X1 Carbon series of laptops. Some concepts may overlap with Lenovo's general practices, a Chinese-American multinational technology company.
Hardware Vendor Lockout (BIOS Whitelist)[edit | edit source]
Most models of the Lenovo X1 Carbon will fail to post if the user changes their WWAN broadband card to a WWAN card that is not on the Lenovo Vendor Whitelist[1]. If a user intends to use a WWAN card manufactured by another company, which are typically cheaper than the Lenovo factory-installed WWAN cards, the computer will not boot until the user removes the card. Evasion of these whitelists has been outlined in the ArchLinux wiki[1], but success is very limited.
The intent behind this vendor-lockout is ambiguous, and not well-documented officially by Lenovo.
Resulting cost for the consumer[edit | edit source]
Lenovo currently charges $298 USD to install a Quectel RM520N-GL 5G Sub6 from the factory[2].
Some used options of similar modems can, at the time of writing, be purchased for $150 USD[3]. 4G modems can be purchased for even less[4].
