So… Lenovo uses SHIT power adapter ports and power adapters. As I write this review, my y530 is sporadically charging and then not, charging and then not. Called customer support to see if warranty can fix it, WARRANTY EXPIRED 2 MONTHS AGO. Also.. The laptop is a gaming one that drains battery WHILE PLUGGED IN. They shipped a 135W adapter when it NEEDS a 170w. What kind of shit is this??
