My power button doesn't work at all. I got one for my birthday the other day, I've had nothing but problems with it.. Yesterday it seemed fine after I flashed the firmware but about 20 minutes into messing with it the screen went black and the unit was unresponsive. I let the battery die hoping that would turn it off so I could just turn it on, now whenever I plug it in my battery charges but the power button is unresponsive. It took me 3 days to figure out what kind of tablet it actually was. (the chinese seller said it was an iRobot but looks almost exactly like this: DealExtreme: $104.90 7" Touch Screen TFT LCD Google Android 1.6 Tablet PC w/ WiFi/Camera (VIA WM8505 ARM926) except with a silver backing.) I really need help with this, the ebay seller said it was warrantied.. then told me the warranty only means I can pay to send it back and then pay to have it fixed.
