Hey got my transformer today but no joy, It wont even power on . I charged it via wall socket for an hour, still wont power on so I tried charging it through usb on my desktop and still no dice. I tried the button combinations listed here http://forum.xda-developers.com/showthread.php?t=1032374 and was able to get a reproducible click noise but no screen movement what so ever. I unplugged it once in the beginning and it made a low battery noise but have not been able to make that happen again. Any ideas?
Thanks

P.S. Should I try this? http://tabletroms.com/forums/showthread.php?976-Nvflash-Unbricking-and-forever-root!
It couldn't hurt to try. It supposed to unbrick bricks.

Tried it. Windows does not recognize the device. Then clicking on properties it states that the device is not working. I'm guessing faulty cable. Will look for a replacement tonight.
As per the instructions charge it for 8 hours with the OEM charger and cable. Charging via the USB is pretty worthless. The charger is rated at 1.2 Amps at 15 volts. A USB port is .5 Amps at 5 volts, way less.
You need to install the Windows drivers to have ir recognized.
Sounds like a dead screen.
Does the power adapter feels hot/warm when you do your charging? Did you push in the power adapter until you hear a click sound?
@greeny2010 Yes and yes,
I will let it charge all night tonight and let you all know in the morning.
Ok I let it charge overnight and attempted to power it on. First I pressed the power button for ~10 seconds then waited ~5 seconds and pressed power again. This time the speakers made a pop noise and I heard the camera click but still no screen D:
Any other ideas? I really don't want to rma I have my final essay due Thursday and I stupidly sold my laptop to get this thinking it would get here and just work.
I read in another post where someone had a similar issue which was due to a bent pin where the transformer connects. I would inspect that carefully.

do you have a mini hdmi? IF so see if you get a picture on your tv. I was able to get a picture on my tv but not on my TF. Turned out my display was dead.
Dead screen The backlight is out. Is there any fixing this or is rma the only option?
sux, RMA it yo

Within 30 days you can always return it, if you can find another one in stock somewhere. Otherwise RMA is your only option

i have asus tranfrormer 9.x.x.x, recovery 5.8.x.x, after i did superwipe , every thing is gone and i cant flash any rom through adb/nvflash saying cant write to sdcard (read only). any suggestions?
Ok, I'll try to make this short and sweet and we'll see what happens. I spent the last 2 hours scouring this forum (pretty much the Bible for the HD2) and some other places and I'm still kinda dead in the water.
Here's the situation:
I just grabbed a used HD2 in excellent cosmetic shape. It was from a pawn shop, for $100 cash, and the device would power up at the pawn shop into Windows Mobile 6.5 just long enough to see Sense starting to load, then the battery would complain (probably hadn't had a proper charge in a long time I'm suspecting), then it would go into the "Goodbye!" routine.
Fair enough. So I get it home, and they included the HD2 USB adapter/charger, and I have my own 100% working microUSB cable. I verified the charger works by attaching it to my microUSB cable and then plugging it into my current phone (a cheapy LG 900g on NET10) and it works fine, no issues for power or data connectivity.
So I unplug the cable from the LG, plug it into the HD2, and attach it to my Belkin USB hub (powered, with nothing else attached to it, no other USB devices) and after a few seconds I get the orange charging light on the HD2. Note, it's still off, I didn't turn it back on after it shut itself off. So I let it charge for a few minutes, then I realize I should probably be better off using the actual dedicated HD2 charger, so I unplug the USB end from the USB hub, the orange light obviously goes out since it's now without that source of juice, then plug it into the HTC USB charger and...
Nothing. Absolutely nothing. No orange charging light, no response when trying to power the HD2 up, absolutely nada. So now I'm frustrated. I disconnect the USB cable from the HD2, take off the back cover, remove the battery, wait about 1 minute, reinsert the battery (leaving the back cover off), attempt to power it up, no luck.
Plug the charger back in, and I can feel]/i] the tiny vibration motor just kinda "tick" ever few seconds; there's something going on in there, I'm certain. Repeat the unplug/remove battery/wait a minute/put it back together/plug it back in a few times, and then I get something:
The HD2 will vibrate and the screen will light up with the "Stick Together" graphic, for about 1/2 second. Then it's off again. Then it's on again, and off, and on, and off. It's a loop of some kind, but it's random. Sometimes the on/off happens every few seconds, sometimes it's 10, 15, 30, sometimes a full minute goes by before it'll "flash" then nothing again.
Now, the whole time this occurs, the orange charging light never ever comes back on again - it has not come on again regardless of whether I'm plugged into the USB hub or the HTC charger, it just doesn't light up anymore, so my current suspicion is that the battery itself is simply so "dead" it won't accept a charge of any kind - at least that's my current hope, as odd as that sounds. I can get a new battery, of course, it'll just take a few days to get one (ain't paying full price here in Vegas, will order something online).
I'm stumped. I check the contacts, they're fine, they were very very slightly bent but they're ok now. I don't know what else to do since it does seem like the battery could be the culprit. It'll sit here and just flash every so often - it's been plugged into the HTC charger for the past 30 minutes straight but, I'm not even seeing the flashes anymore (the past few minutes I've been typing this post).
Maybe the battery is to blame, I don't know, but I'm hoping that someone can say "Yes, that sounds like a completely toasted battery to me, get a new one" or whatever.
Any opinions? Anyone seen this particular behavior before? I do a search for "reboot loop" and what I find are people with HD2's that get stuck at the "Stick Together" screen and, well, that's not what's happening here - it shows that, for a 1/2 to 1 second on occasion, then nothing. The vibration motor kicks in when the flashes occur, as well.
It's like it wants to fire up but just doesn't have the power to do it - and since the charging circuit isn't kicking in (no orange light), well... that's my guess.
That's about it. If anyone has any advice, I'm reading.
Thanks, and have fun, always...

Do you know what short means? p joking, just next time don't make it too long)
You won't get replies if your question is too long, because they won't bother reading it .
Anyway, back to topic.
Your battery has no juice, and for some reason the HD2 automatically boots when (no juice in battery and plugged into charger) .. you need to unplug cable, remove battery, plug in cable, wait for a minute or so, insert battery .
Firstly try the above which should stop the phone trying to start,, but two other things, firstly the battery pins bend real easily, so since you've been doing a few battery pulls, keep checking them. Second, a really REALLY discharged battery may have so little juice it wont start charging , in which case you can try the 'bare wire USB Lead charging method, where you get an old mini /micro USB lead, cut end off, bare red and black ,red to + black to - on the battery, into wall charger for around a minute, back into phone, real USB lead in, and hopefully it now has enough chrge to start booting and charging properly.
Turned out to be the battery itself - went back to the pawn shop, took the battery from the one I purchased and placed it into a known working HD2 still on the shelf (another as-is item) and attached the microUSB cable and charger, no dice: same exact issue.
Took the battery from the second HD2, put it into my HD2 that I purchased, attached the microUSB cable and charger, wham bam we're cookin' with fire now.
So I paid the guy $10 to let me swap the batteries and keep it hush-hush (I'm in there all the time buying used busted stuff anyway), came home, gave it a full night's charge and so far so good. Got NexusHD2-Gingerbread V3.0 NAND by tytung on it in about 10 minutes, and it's smooth as silk so far.
I appreciate the responses, thanks.
Hello, I have a 16gb, bought from google Nexus 7, and three days ago I was using it, 55% of battery, connected to car charger when I put it to sleep and let it charge, after a couple of minutes I picked it up and it wouldn't turn on. I noticed that the screen was on, but black, and nothing that I did would make it back on or off.
After an hour or so it was off, to never turn on again... Already tried holding power, power + down, power + up + down for 30 seconds, 1 minute...
Let it charge overnight, it only heat up very much, but no signs of life...
Any help?
I bought it in the USA and now I'm on Brazil and have no warranty...

I'm not electrical engineer, but it sounds like your charger did something to mess it up. If I was in your position I would probably disassemble mine and, while I don't know if this is possible, disconnect the battery, and plug in the USB to the charger that you got when your Nexus. Whether this will permit your device to boot, and allow you to determine whether the battery is fried is unknown to me, maybe someone else who has more hardware hacking knowledge could give some input here. Found this link, might be helpful.

Yes, it is possible to remove the battery, but I'm having trouble removing it... It seems that it's glued to the chassis... When I plug it to charge I can hear a very discrete humming noise... it's normal?
No other help?
Asus put a protector in the software, any time this happens hold the power button down for exactly 30 then it should boot up.

There is a bit of a difference between a standard AC charger and a DC charger. The biggest issue with car chargers is that you cant always regulate the voltage. Its not uncommon to have surges when things requiring electrical. I have heard (and seen) that Asus devices are particularly sensetive to this. I had an Asus Transformer Infinity that failed to boot ever again after "incorrectly" charging the device (that was Asus' words, not mine).
Tried a good battery... no show
My wife's Nexus 7 suddenly won't turn on... It still had juice when she went to charge it, but the next day found it was totally dead.
I've tried different chargers, tried to get to the bootloader, opened it and unplugged the battery, hooked it up via USB to my computer, etc and nothing will get this thing to power on.
Any ideas?

I mean, how long did you leave it on AC power? I know when I drain mine since coming to KitKat, it takes as long as a half an hour to respond again.

If you haven't already, try holding the power button for a while until *hopefully* the Google splash appears.
A good way to tell if the device is accepting a current is by using a charger that can verify this somehow, like with an embedded LED. One like this: http://www.verizonwireless.com/accessories/rapid-wall-charger-with-6-ft-cable-for-micro-usb/
I used this for my HTC Rezound when it still worked to make sure it was taking a charge because it would report it was charging in the OS but the charger module itself reported otherwise (the red Verizon ring didn't illuminate unless the charger was positioned a certain way in the device thus this was the only way I could supply it a charge and not hope it wasn't dead in the morning). When my Nexus 7 is drained, it draws enough voltage to get the charger to illuminate so maybe try one of these to really make sure it's still responding.
For the meanwhile, if you do decide to buy one, what was the last thing you/your wife had done? Was there root access?
U need press power for 2 min and need to be pluget into wall

Interesting about the charger -- don't think I have one that does that. Maybe I'll see if my VZW store has one, not sure yet.
She had just used her tablet as normal, and plugged it in like she does every other day or so -- the next morning grabbed it and went to work only to find out that it was dead. IE: not turning on.
- No root access (totally stock)
- I've tried holding the power button for up to 2 mins. - nothing
- Even tried holding the down volume and power for up to 2 mins. together - nothing
- Removed the back and unplugged the battery (plug was really tight) and left it undone for 5 mins and reconnected - nothing
- When plugging in to a USB on the computer, the computer dings like I connected something but - nothing
Perhaps I'll take it apart again and see if I can get a voltage reading on the battery with my multimeter... didn't do that before, but would be good to know if it is charged and not turning on or what.

Remove the back cover, locate the plug to the battery, disconnect plug by sliding from right to left, then replug. Should be fine after that.

Thanks but I already did that. Nothing changed. If I don't get it going soon I'll be forced to buy something else as she is getting impatient.
I have the same issue.
I bought a refurbish one and it was working great for 2 days and yesterday when I tried to open it, it won't turn on anymore and I was able to browse on it 5 min before.
I tried everything but I cannot find any solution...
When I plug into a wall I cannot see the charging icon and when I plug it into my computer it will do the noise that a device is plug but nothing happen... I wonder if its the battery that is crap

I own 3 of these N7 tablets and this has been the number one issue. Sent one for repair when it was under warranty. The supplied Nexus wall charger burn out quick, and aftermarket cables last only 3 months. I've had better results using the Samsung wall charger and cable.
OP, it sounds like your wife's N7 is in APX mode. Connect it to your PC via a USB cable, and open Control Panel's devices and printers panel. If it sees an APX device, and you didn't make NVFlash blobs, your only recourse is a motherboard replacement.

I just got my new N7 32gb GSM 2012 in the mail today. Won't turn on at all. I'm not going to bother. Going to return it. Quite disappointed, as I didnt realized this issue (apparently with the battery) was so common. Was looking forward to flashing cyanogenmod. Poop. Might just get a samsung tab now, which I think is quite overpriced for its specs.

If you're seriously looking for something other than an N7 then I'd suggest you look at the LG G-Pad.
I bought one for my Dad at Christmas and was amazed by how good the screen is, and the tablet generally, for the price. The LG skin is minimal and can be changed obviously with another launcher, and the battery life is better than my N7.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!

let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.
