Microsoft Surface Pro 2 will not boot up

I found the other day that the Surface Pro 2 decided it would no longer turn on!!

It appears the device had gone into some kind of deep hibernation state, whether to avoid overcharging or due to an Application altering the system I'm not sure, anyway this is how to get it back to normal:-

On the Volume key on the left side press the increase volume rocker whilst you press the Surface Pro 2 power button...This can take 20 seconds.... when you see the Surface logo appear let go of the buttons. Then press the Power button as normal. This should allow the device to boot normally.
