I'm going crazy with this problem. So I hope someone can help. Recently bought TF201 (March2012), automatically updated to ICS. Noticed almost immediately that sometimes I would hit the power button up top and the screen would flash the login-in screen then immediately go black. Sometimes it would stay on and I could log in, other times it would keep doing it frustrating me. I've sent ASUS 2 emails regarding the problem nothing so far. I've isolated the problem to the charging cord. I can successfully log in and out without problem when not charging. However, when i put my charging cord in, the problem starts, I'll hit the top power button to sleep the tablet, but when i push the power button again the login screen will flash and then the screen will go black. Pull the charging cable out and i can login no problem. Searched the forums and google, but i seem to be the only one with this problem. Hope that isn't true... Thank you.
