Wont turn on

Tap "Install" on the next screen to confirm. When Flash is installed, head into your phone's stock browser (again, Google Chrome won't support your newly-installed Flash apk). On Android 3.0 or later, go to Menu (three dots next to the address bar on some phones) > Settings > Advanced > Enable plug-ins.

Important:Plug your device into power outlet

Step 1: Power off Nexus 7
Step 2: Power on while holding Volume Down/Up
(enter BootLoader)
Step 3: Press Volume Up to toggle to "Recovery Mode"then press power to select
Step 4: Hold The Power Button and tap Volume Up when you see "No Command"
Step 5: Press & hold Power Button & Volume Up Button Again
Step 6: Toggle with vol down and vol up / power at wipe data (all data) & reboot

Only thing to really do is wait for the battery to die all the way, then try the hard reset after it charges up a little bit.

Press and hold Volume Down, and then press and hold Power simultaneously until the device turns on.

Hope that helps!

I've got one also, so that's a worry. You mean you have tried all this stuff?

It seems to be a common problem

The microphone for the nexus 7 is a small hole on the right hand side of the tablet, just below the volume button. Make sure your hand and any cases you're using aren't covering this when you're trying to do a voice search.

You can try a hard reset. Hold down the power button and the volume buttons at the same time. The device should then power on and you can follow the on-screen prompts.

Hope that helps!

The battery connector in the Nexus 7 (2012 model) is notoriously problematic. Sometimes dropping the device can cause issues that prevent the Nexus 7 from charging altogether. A hard reset may not work. Fortunately, it is quite easy to fix.

However this will void your warranty. Pop the back of the Nexus 7 case open by pushing a credit card or guitar pick or small screwdriver under the edge of the black plastic case. Start from the top and gently pry the case open, working your way around. The back of the case will come off quite easily. The battery occupies the bulk of the left-hand side of the unit, and a group of six wires come out of the top of the battery to a connector on the circuit board. Gently push the plug out of the socket connector, wait 15 seconds, and push it back in. Snap the case back on and plug in your charger. You should now see the battery charge image appear.

Sorry to hear/read this.
First, try get a new charger and plug your Google nexus 7. Suspect a dead battery with no charge left on it.

Otherwise, confirm your charger isn't just lighting up whereas it isn't delivering any charge current to your device.

Next to try if your ac charger is confirmed good is to attempt replacing the battery; at the store, have them insert a compatible/similar battery and then try power on your device.

NOTE:
New batteries at the point of purchase have some charge on them; sufficient to power on your device.

Device not power on, DON'T PURCHASE NEW BATTERY. Obviously, you don't have a power/battery problem.

Device power on, then you either have a battery that has failed or that your device's charging port needs to be serviced or repaired.

Please post update/feedback asap. Thanks
