My nexus wasn't waking up, I even thought it had died cause I pulled out the battery and it wouldn't turn on even after that. Tried a different battery and nothing would happen, wouldn't turn on charging light or anything. So I took it all apart and tried to turn on and it did, so I assembled it all together again and it was back to working... then it went to sleep and wouldn't wake up, notification light was blinking and everything, so I reverted back from 1.4.2 hwa to 1.4.0. Haven't had a problem since, but reading the latests posts, I'll see if I can mess with the screen state to fix the deep sleep.
