I have a Lenovo V570 won't charge or turn on. It's my wife's laptop and she used it until it died and let is sit for a few months and now needs its. I tried hot swapping the battery to start charge and nothing, no lights on in front panel at all. The AC adapter light is orange an lit (not sure if it means anything) but it won't turn on or charge at all. Should i replace the battery and adapter or try one then the other or is there a larger problem at fault. Thanks for any advice you can give me.
