The battery had gone down and I had left it charging. After a few hours, nothing! I have tried different outlets, the light on the charger is on - but I get no response from any combination of power/volume buttons or anything. :cry: Could it be the battery instead of the device? Has anyone had experience exchanging their device? I use my Surface everyday at work and am hoping the turn around time isn't too long. If anyone has any ideas on how to revive a bricked Surface before I send it back, please share. Thanks!!
