Hi! Unfortunately the power balloon option is not going to work because it will take years for the residual power to drain off the motherboard per the advice of another contributor on iFixit who has more computer electrical engineering than I do. This is how the motherboard is able to retain machine language and BIOS when the hard drive is removed or the battery is removed or if the laptop is not plugged in. That is the same no power source whatsoever except for the residual electrical charge already on the board.
