Glo HD Bricked?

[engstedt]

My Kobo Glo Hd screen say "Sleeping please charge your reader" the red light is on.
I've had it connected to a computer all night for charging. On the pc i can see the "Se blank megrez" so the cable works.

I've tried a new sd card with a new image with no response at all.

I've tried reset with the small hole next to the usb port with no response at all.

I've tried reset with holding the button and tapping the lower corners with no response at all.

the only ressponse i can get is when the ereader is connected with the computer i can hold the button down and the "se blank megrez" disapperar from the computer and the red light turns off, the light is off until i push the button or reconnects the ereader to the computer.

I've disconnected the battery with no response at all.

Is there anything more i can do?
