Nexus 7 refuses to boot unless plugged into outlet
We'll there is no fix for this. I have had my N7 for one month and it is doing the same thing described--if it is not plugged in it will not start up. So here is what I have experienced relative to this problem.  First the N7 I just pulled out of the box did the same thing. So I brought it back to the store to exchange it and to be safe I tried the next three at the store and they all had the same problem.  The fourth one worked for a month. Now that it will not start up I called Google they would help only if I bought it through the PlayStore.  They passed me to Asus who gave me only one option -  return to have it repaired not replaced.  I am very disappointed in Google.  They know they have a problem but do not want to say so in the public. Very sad
