The connector that comes into the laptop, shaking with my Lenovo G555 a little bit, which affects the function but not in any way. Not so with the cord from the outlet to the transformer. If the cable breaks here once wrong move quickly once the power from what is annoying, especially if you have no battery in the unit. Luckily I had still from my old (original) Netztteil this cable. It fits much better and since I have no more problems with the current connection. If this error is resolved is worth also easy 5 star.
