So an 4.0.3 upgrade to the OS was pushed. Before the upgrade I just tapped the power button and the device would go to sleep. Then another tap woke it up, ready to go. Now, after the upgrade, when I tap the power button I get a dialog asking if I want to power down. If I reply "no", the tablet goes to sleep. For a short while. Then it starts to flash it's screen at me: Turn on, go dim, go off. Rinse and repeat. I guess the tablet want's to be off between uses? But that forces me to sit through a restart when I turn it back on. Anyone else seeing this?
What you describe may be a hardware problem, where the power button may be sticking or shorted. It seems worth trying the available resets before getting hardware service though. I suggest starting with the hardware reset (pinhole). If that does not work, back up any files that you wish to keep to external storage, then go to Settings > Backup & reset and perform a Factory data reset.
You may be right. Because it's behaving correctly now. I just just assumed that it was related to the OS upgrade.
