Lenovo B480 has no signs of life beside the battery charging led blinks for 1 time less than a sec..when the charger is plugged in. The PCH chip get really hot..Also the S5 and S0 state diode connected to the pch is bad (readings in both direction in diode mode)..No one has the boardview for it or I could not find one I purchased a B460 which has the boardview..So lost with this board...
