Tried the power button for 60-90 seconds, still nothing on screen. In the past I've been able to plug in the charger when this occurred and it would pop the screen on, tried that, but got no results.
I tried plugging it into my laptop to see if I could get ADB active and do a reboot. Windows saw the device and loaded the ADB driver, but if I tried adb devices it showed no devices. I long pressed the power button again and the windows device manager reset, adb devices now showed the transformer, but in offline mode. I couldn't run any commands.
Next I tried the "soft reset" utilizing the volume up and power button. This didn't do anything, except that the next time I attached it to my laptop it prompted me for an APX driver. I didn't know at the time this was for NVFlash (I rooted my device before the SBK was out with the initial blob tools from androidroot.mobi).
Now when I hook up my transformer I get no response from my computer and no response from the buttons on my tablet.
I'm at a loss and would love any suggestions or ideas to get my tablet back up and running.
