Our z510 was used on Tuesday, but yesterday plugged in and no lights. It is completely dead and will not charge. We have 2 adapters (the original and replacement from Lenovo--lost and then found). Neither will charge the battery.
I have kept up with all updates prior to this happening. (The only other problem we have had is the screen becoming dim (very difficult to see). I had to keep installing an old driver because when it updates, the screen becomes dim again.)
I can't try the firmware update because it will not turn on.

Thanks! I tried you solution and it worked. Though I didnt do it completely.. I opened up the keyboard then i was afraid to proceed further.. so i tried shaking things around pressed the power button couple of times and then put the screws and keyboard back to original. then I connect the charger but their was no light.. i let it be for sometime say 5 mins, then the battery charge light lighted up to blink, i switched the laptop on, it was working again.. the battery was however <5% then... but this worked, i am glad.
