I have a W530 with the i7-3520M (dual) processor, when I placed my order I chose the 135W power adapter. I also purchased a 170W to keep plugged in at my desk.
I was wondering if anyone knows why the 135W charges the laptop in 2 hours and it takes at least 4 hours for the 170W to charge it? I thought the 170 would charge faster and that's why I ordered it to keep plugged in at my desk. The 170 was purchased directly from Lenovo.

Could you connect a physical power meter between the wall socket and your power adapter and measure the actual power consumption to see if the 170W transfer less to the computer than the 135W?
