There is no battery to remove.
I unplugged, held power button in for a minute. plugged back in, pushed power button, same result. Whirls for a second, backlight for keys comes on then nothing
sorry for delay, had to find a flashlight.
This is a touch screen (not sure if it makes a difference), but when I shine the flashlight at the screen I do not see anything at all.
are you sure? because this happened yesterday and after a while it started up fine.
