Problems with my Nexus 7

Hi everyone. I am new here, but I have a problem with my tablet.

It happened on Sunday afternoon. I opened my tablet and the screen randomly turned off it'self and now, I cannot get it back on. I tried holding down the power button for 15-30 seconds and nothing happened. I also tried holding down the power button and the down volume button at the same time and it also had the same result, nothing. Then I also tried holding down all three buttons and nothing happened. So, I did some research, and some people said it could be the battery. I even took off the back cover, took out the battery, put it back in the connectors, and nothing happened. So, I'm pretty much starring at a blank tablet that won't do nothing. I have no warranty and I bought it two years ago on Christmas of 2012.

If anyone can help me, that'll be great. If not, I understand! Thanks a lot guys.

P.S. I also downloaded Nexus Toolkit and that won't help me, too.
 
Hello, Nick, welcome to Android Forums! :)

It sounds like you're having the same issues as a couple of our other members... check these threads out:

There's one post in particular that could help you out:

My nexus did the same thing, it has to do with the power save feature. I googled the issue, after charging with the original charger for about an hour . I used the hold the power button, for a good 2-3 min. Let go then try the tap the power button 4-5 times then hold it again..first time no joy but unplugged power , replugged and on second try got the battery logo.. Rebooted it ,then actually shut it down, then completely recharged it. Since then no issues...

Hope you manage to get it sorted!!
 
Thank you D-U-R-X.

I tried majority of those options, but nothing happened. I even let my tablet charged all night, hit the power button, and volume buttons, and nothing happened. I'm running out of options.
 
I've not had this issue myself... if you've tried the power button combo/etc. mentioned in the post I quoted above, then I'm not sure what to suggest - sorry! :o

Perhaps someone else could offer a suggestion?

I hope so. I'm plugging it in to my computer (Windows 7) right now, and it's making some noises. Sometimes, It'll say "USB not recognizing" or something like that.
 
Have you tried a different USB cable? It's possible that the battery is not charging at all or insufficiently to power the tablet when the battery is dead.

Many N7 charging problems turn out to be USB cable related.
 
Make sure you are using the power adapter (vampire) that came with the tablet or one that states its output is 2amps or greater.

The Nexus will never charge using a typical phone vampire or plugged into a computer unless the computer USB supports 2a charging mode.
 
Vampire? Lol.
My n7 charges from my 1.2A sammy charger but only just enough to keep it alive while using it and charge by maybe 1% every 5mins

They are called vampire's in energy conservation circles as they have two prongs like fangs, and more importantly are always sucking electricity when plugged in even if not being used.

The wall adapters are inductive, they have an internal primary coil of copper wire that is wound around a secondary coil of wire. The fangs are attached to the primary winding and your phone gets power from the secondary.

When plugged in the primary winding always has power flowing through it even if there is nothing connected to the secondary.

If you think about how many of those little black adapters you have in your house, how they are always on, and multiply that by how many there are across a nation of people.. They are little vampire's sucking our electrical grids dry, just very slowly.

;)
 
Ahh understood man. Yeah i know how induction works and i gave up tryin to explain it to my wife lol :D
In UK we have 3-pin wall plugs so thats probably why i didnt get the vampire analogy :beer:

Ahh yes, mandating the ground pin is a much safer system overall.
 
Yeah, in most appliences the earth pin isnt even connected but on high wattage and especially metal bodied things it is. The (longer) earth pin going into the wall socket opens up the holes for the other two pins though so it has to be there (on a phone charger for example the earth pin is plastic lol).
So how do things in the US get earthed? (Sorry for goin off topic op) :beer:

If a device does not have a ground its usually because the device is electrically insulated in a manner that it would only pose an electrocution threat in extreme cases, like full submersion in water where in theory a circuit would trip anyway.

Fundamentally it is still flawed, a grounded device is a inherently safer one.
