Press "Ctrl-Alt-Del" to restart the computer if the PC boots to Windows before loading the setup program. Repeat Step Two following restart.
Recharge battery and hold the delete key as soon as you turn it on. Keep holding it.
I apologize that I am out of suggestions. I would call Asus and ask for help. Even when out of warranty if you just ask the question they are pretty good in helping out.
Let me know if you would like me to opt out to see if someone else can help you.
