Sony VAIO won't turn on without power cord

  1. Hey All

    Have this annoying problem with my Sony VAIO VGN-TXN25N. The laptop will not power on without having the power cord in and plugged into an outlet, even though the battery is fully charged. Once the machine is powered on, I can remove the cord and run on battery power like normal, but it is obviously annoying to not be able to turn the machine on without plugging it into the wall. For whatever reason the little white power button is unresponsive until it is plugged into a wall outlet???

    I tried to contact Sony and they kept telling me to install some graphic/video driver, which I did to no avail. If anyone has any insight I'd love your HELP!

    Thank you
