Last night my Aura HD informed me it had run out of battery (despite showing 30% only a day or two ago) but now I come to recharge it there's no sign of life. I've plugged it into it's USB cable (the same port I used to transfer books) and despite having been plugged in for several hours the power switch doesn't do anything. The light that usually comes on isn't coming on and the screen is completely white.

This is the first time I've flattened the battery so I'm not sure what's normal but it does seem like something is wrong.

With the sudden battery drop I did turn it on and off a few times to make sure it wasn't a glitch. Among a couple of low battery warnings I did see a black screen with a progress bar that said something like restoring but I don't remember the exact actions I did with it after that.

After seeing no life after a couple of hours on charge I did try the reset switch. This caused the screen to flash (black white black white) and the power light to come on (steady for a few seconds) but no activity otherwise.

Before I contact kobo support is this a known problem or can anyone suggest a possible solution? It's one of those ones that's difficult to search for and I haven't found anything relevant.
