The Lenovo X1 Carbon is a laptop series made by [[Lenovo]] advertised as portable, thin, durable while offering "full PC power and functionality".<ref>{{Cite web |title=Compare Different ThinkPad Models {{!}} Lenovo Egypt |url=https://www.lenovo.com/eg/en/faqs/laptop-faqs/best-thinkpad-for-you/ |access-date=2025-08-22}}</ref>

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)===
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.<ref name=":1">[https://wiki.archlinux.org/title/ThinkPad_mobile_Internet "ThinkPad mobile Internet"] - wiki.archlinux.org</ref> 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 Arch Linux wiki,<ref name=":1" /> but success is very limited.

====Resulting cost for the consumer====
Lenovo currently charges $298 USD to install a Quectel RM520N-GL 5G Sub6 from the factory.<ref name=":0" />

Some used options of similar modems can, at the time of writing, be purchased for $150 USD.<ref>[https://www.ebay.com/itm/296886818084 "Quectel RM520N-GL"] - ebay.com - 17 Jan 2025 - Archived Page: https://archive.is/IkmZV</ref> 4G modems can be purchased for less.<ref>[https://www.ebay.com/itm/196914042141 "NEW Dell V8KN6 Sierra Wireless AirPrime EM7455 DW5811e LTE 4G WWAN Card"] - ebay.com - 17 Jan 2025 - Archived Page: https://archive.is/uSubr</ref>

==='''Repairability and upgradability'''===
The 10th gen Lenovo X1 Carbon uses soldered RAM<ref>{{Cite web |last=Iliev |first=Alex |date=14 Oct 2022 |title= |url=https://laptopmedia.com/highlights/inside-lenovo-thinkpad-x1-carbon-10th-gen-disassembly-and-upgrade-options/}}</ref> which makes upgrading it impossible. The display and the bezels of the LCD are glued together, making replacing just the LCD without replacing the entire lid complicated.<ref>{{Cite web |title=SOLVED: How to replace the LCD screen without replacing the whole lid? - Lenovo ThinkPad X1 Carbon 10th Gen - iFixit |url=https://www.ifixit.com/Answers/View/772580/How+to+replace+the+LCD+screen+without+replacing+the+whole+lid |access-date=2025-08-22}}</ref>
