I've had similar issues since using the mobile keyboard. It worked for a couple of days, but now it crashes any time you disconnect the tablet from the keyboard, and it can't be turned back on until you plug the charger in! And now it's getting worse, I have to keep it plugged in or it crashes! I hope I'm not alone with this problem :/
I have the same problem. Just started tonight. It vibrates when I push the button, but nothing else happens. Screen just stays black.
I have a for me reproducable issue:
After that.. push power button and device starts normally...
At the moment the tablet is a paperweight as it is either out of power and charging or in some state in which it is unusable. My happiness clearly has changed to some other feeling with this tablet... What I find strange is that the newssites are not reporting about this 'great device' (Which it would be if it would work as advertised)...
I had this issue this morning. Aggravating! Since there were no answers that worked on this dialog, I looked up another and found a solution that at least worked for me. If the Venue won't power on, and you know it's charged, hold the power button for 20 seconds, then hold it down again for 1 second. It should boot normally after that.
I tried this but unfortunately it did not work on mine. I just finished my second chat session with Dell support and they are sending me a box to ship the computer back to them. I guess there is no easy solution to the problem.
