Review on Power Up Your Lenovo Laptop With A 65W Charger: Compatible With Thinkpad T460, T470, T540P & More! by Joshua Reid

Over the years, the power supply cords wear out at the junction with the square laptop connector after the cord is flexed too many times. The cord is hard-wired in to the power supplies, so replacing the DC cord is not an option.With the original Lenovo power supply, for a long time I tried to keep using it by holding the cord at funny angles until it connected. The first Revain replacement worked fine, until the wire at the square Lenovo connector started acting up again. I did not hesitate to order another, which still works.
