I encountered an issue today that concerned me quite a bit. An hour or so after setting my TF101 and dock down, I opened it up and found it at the black ASUS reboot screen. Then the screen went black, rebooted over and over and over. It would not respond to a single press of the power button.
I regained control by holding the power button down for about 10 seconds, or until it seemed that the screen was staying off. Once I released the button, the ASUS logo came up again, and then went to the startup screen with the rotating circles. A few seconds later, it was back up again.
Hopefully that was an isolated incident, but it does concern me a bit. Earlier today it took 5 minutes or more for the "DUAL BATTERY" indicator I use to detect that there was more than a 0% charge on the dock battery, after an overnight charge. After it came to its senses, it registered 98%.
I still haven't been able to wake the tablet with the keyboard, even though keyboard powersave is not checked.
TF101 - B50
Dock - B80
