Internal Lithium Polymer Battery
The internal Battery Management System (BMS) in X1 Carbon units can trigger a safety lockout if it detects cell imbalance or excessive cycle wear, leading to a 'not charging' status. Replacing the battery solves the issue if the internal cells have reached their end-of-life or if the internal fuse on the battery's logic board has blown.

Lenovo 65W USB-C Standard AC Adapter
USB-C Power Delivery requires a handshake between the adapter and the laptop; physical damage to the adapter's pins or a failure in the adapter's internal switching circuit can prevent the laptop from negotiating the 20V charging profile, resulting in the laptop drawing power but refusing to charge.

Replacement System Board
A known pattern failure in X1 Carbon models involves the Thunderbolt controller firmware or the physical USB-C ports soldered to the motherboard. If a BIOS reset and a new adapter fail to initiate charging, the charging logic on the system board is likely defective, requiring a full board replacement.
