Hi,
Had the same problem as well.
Your battery may have to be reset. Unplug laptop from AC power, remove back cover and unplug the battery. Unplug the cmos battery and hold down the power button for 30secs to drain any residual power that could still be on the motherboard. Plug the two batteries back in, put the cover back on. Plug in AC power and let it charge for a bit. Hopefully after you turn the laptop back on it should show a charge, unplug or while and see what happens. Good luck
