Lenovo ThinkBook-IWL charging IC

[alex.goodnetter]

Does anyone know what charging IC the Lenovo ThinkBook-IWL uses or is compatible with? The reason I suspect the IC is faulty is that it could only charge if I unplug and replug the power cable a few times. I also tried replacing the charging port, battery, and charging cable and had the same problem. (It is something I could live with, but I'm thinking of selling this laptop).
