I wanted to see if anyone else was experiencing this.
I keep my Prime on at work, on a little stand next to my computer monitor. The screen will turn off and go into standby, but a few times today when I press the button to turn on the screen, I've found that the Prime has shutdown completely, and I have to wait for it to go through the startup process.
Happened to me last night at home. Went to use it and it would not turn on. So I charged it overnight and had to hold the power button for about 10 sec this morning and it rebooted. Hopefully not a reoccuring problem. I have only had it for 24hrs.
I think this is what has happen to me also two times. It seems like it has not battery because you hold the power button on for a very long time. Not sure if this was something with honeycomb or just the Asus Prime.
I have had the same problem twice now. I charge overnight and when i tried to turn the screen on in the morning noting happened. I had to hold the power button for about 10 seconds to get it to boot up. It has only happened twice in the past 9 days. I hope it is just a software bug and ICS fixes it.
