Last night I updated my RT tablet with the 8.1 update. Today when I connected the charger, no light. Before rebooting I looked at the battery icon and it appeared full. I tried rebooting the tablet. After the Surface splash, I got a low battery indicator and it shuts itself off. I've connected the charger for an hour and it still won't boot up. Aaaaand the warranty only recently expired. I haven't found anything via google, anyone else have the problem?
