If a ThinkPad T14 Gen 5 will not charge, test the charger path first: a different outlet, the charger that came with it and a USB-C cable that is not damaged. Then check for a charge limit. Lenovo Vantage and the BIOS can stop charging at a chosen level such as 70 percent, which looks like a fault but is a setting. If it charges on one USB-C port and not another, the port is at fault.
