The ThinkPad X1 Carbon Gen 13 charges over USB-C with a 65 W adapter, and charging problems follow Lenovo's usual ladder: try the original adapter in a wall outlet, try both USB-C ports, check the cable, and look at the charge light. The Gen 13 can also be charged through a dock, and a dock that provides less power than the laptop draws leaves the battery falling while plugged in.
The checks in more detail
Lenovo Vantage has a Battery Charge Threshold that stops charging at a set level, which looks like a fault; check the thresholds. The ThinkPad's battery and power settings are in Vantage and in the BIOS. A power cycle, disconnecting everything and holding the power button for fifteen seconds, resets the charge controller. Lint in the USB-C port causes loose connections. If the laptop reports a non-Lenovo or low-power charger, it limits charging. Update the BIOS.
A battery that does not hold charge after these steps needs service, and the emergency reset hole can restart a frozen controller. ThinkPad chargers have a clear LED on some models and the laptop shows its own light by the port, so note which light behaves how: a steady white light means charging and an amber light means a battery problem or a threshold.
A USB-C cable of the right rating is as important as the adapter, because a thin cable limits the power and the laptop will charge slowly or not under load. Keep the BIOS and the embedded controller updated, since charging fixes arrive that way, and, if the battery cycles heavily, Lenovo Vantage's battery health report shows its condition. If the report says the battery needs replacing, a Lenovo service visit is the next step, and the laptop remains usable on mains meanwhile.
