I just opened my new lenovo 900 and began setting it up for a co-worker. i let it do windows updates, came back to it and for some reason the password i set was not working. I attempted several times to log in then decided to reboot to try to get to the reset utility to factory restore the computer. After a few resets and trying to hold F2 on an external keyboard while trying to turn it on the computer just refused to turn on and the power button is staying lit - never shutting off.
