New TF OTB, won't turn on? DOA?

New TF out of the box, charged (apparently), and it will not "turn on".
Note, this is a gift for my father, so my sister is in possession of the TF.
She charged it overnight and this morning, she pushed the power button ... nothing.
She went into a dark bathroom and could see the backlight on... nothing on the screen.
Went through the following:
1. Held power button down for 20 sec - nothing
2. Held volume down + power - nothing
Questions:
1. Is there supposed to be a light indicating that the TF is charging?
2. Is there a way to "reset" the TF?
3. Could the TF be in SLEEP?
4. The AC adapter ... is this 2 pieces? does the outlet portion separate from the cable portion?
5. Is this unit DOA?

Check that the 2 parts of the AC adapter are firmly pressed together. It sounds like it wasn`t charging.

She cannot separate the two parts. Is this supposed to separate easily?
Heard reports of damaged AC adapters. True?

Just tried to separate mine and couldn`t.There is a post about chargers but i`m afraid you will have to search for it. It was related to chargers not working i think (sorry i didn`t pay much attention as mine was fine)As far as i remember there are two different serial numbers for the charger. One was ok the other dodgy.
Sorry i can`t help more,

my tablet turns on as soon as I insert the charging cable... I don't need to press the power button

She tried a different USB charger, and no go. Still acted the same.
System did not boot...just a blank screen (visible in a dark room).
Sending it back to Amazon.

I have the same issue except that the backlight won't even turn on. Quite upsetting.
did you ever find a resolution?

Make sure you hold the power button for at least 8 seconds. If the battery is charged it should turn on. If it still doesnt you probably have a charging issue. (like a bad plugin trandformer). Try another power source. You can also hold down power and then plug in power cable and see if that wakes it up.

So I've made a bit of a discovery that leads me to think the unit is defective.
When I use the method you mention I hear a clicking sound which I think I've correctly identified as the tablet turning off. Once I hold the button 2 more seconds, Windows recognizes the tablet and has installed the proper drivers so the tablet is on at least at some low level.
The screen however remains black even in a dark room (no backlight visible). I have looked but I cannot seem to find an Asus tech support number for this tablet. Also because I can not get the screen to turn on I can not activate debug mode so I cannot get into ADB.

Try Nvflash, should fix any brick. If Nvflash doesn't work it's pretty much a DOA for sure.

Nexus one wont power back on after reassembly xpost from QA. Please advice.

Hey guys, my LCD broke, It was a AMOLED not SLCD, I bought this piece off ebay:
http://www.ebay.com/itm/260900702599?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I put everything back for the second time now, first of all the device doesn't come on, but when I plug the AC power it shows charging light.
I'm pretty sure my old screen is AMOLED..
I made sure all the connectors where tight on the board. any help?
It wont power on, did I break something?
I'm pretty screwed guys, been at it for like 5 hours I'm done for tonight
Here is what I've conluded. I detached the digitizer from the lcd I made a mistake and removed the factory "tape"
Is and in the process the little power button came off.
So what are my chances now?
Can the digitizer be taped back to the lcd? or Do I need to get a new digitizer which includes an LCD? so as to preserve the factory tape?
As far as the power button goes, I'm not talking about the plastic bit, I'm talking about the actual button underneath. It seemed to be holding on my a little thread anything. Is that "thread" a connector or the button functions fine without it?
I put iit back and sealed the phone up, it seems to be pressing. But of course the phone wont still come on :/

Have you tried the "jump start" method for people with broken power buttons? ie, plug the phone into the wall with the battery out and insert the battery. It might take a few insertions for it to work.

this happened to me last weekend when i replaced my trackball. my power button gave out.

That cable is a major issue with our N1s. You can order a replacement on ebay (or other sites) for usually around $40. It is called the flex cable.
The jumpstart method should work assuming nothing else is screwed up. But it isn't an exact science. Usually if you have your charging cable plugged in, you pull out the battery and put it back in, the phone will vibrate after a few seconds and start booting. If it doesn't, pull the battery out and try again.

So..my nexus 7 won't turn on..

Recently updated my n7 to 4.2, haven't done anything beyond rooting. I woke up this morning, watched an episode of Prison Break via Netflix and went to work. I always plug it in before I leave, and it was saying it was charging before I left.
I get home from work today, and upon trying to unlock the device, it doesn't turn on. I unplugged it, checked the plug in it was using, even tried multiple different electrical sockets. Plugging it in usually brings up the off charging animation, but nothing. Anyone know what might be going on?
My sincerest apologies if this has been asked/questioned before; I did a little searching before I posted this and couldn't find anything about it. Thanks in advance.

Try holding down the power button for 10-20 seconds.
If that doesn't work, try leaving it plugged in for a couple hours and check back on it.
Also try plugging it into the computer and seeing if your screen has gone bad, the Nexus 7 should still come up if it's on.

...I really can't believe I made a post for this..rofl. Thanks a lot, I guess I'm just a little too impatient to hold the power down longer than five seconds.
If mods wanna delete, feel free.

Try holding down vol up & down buttons and then the power button. Then you should be in the reboot/recovery menu. It should say start. Push power button to power up.

Had the same issue today...thanks to all for the quick and easy fix...feel like such a dork!

I'm having the same problem, last night I tried to turn on my Nexus7 and had issues.
My device is locked and upgraded to 4.2
While booting, the device would get to the lock screen then immediately power down. While it was powering down the screen would fuzz over and glitch a few times. As soon as it turned off it would repeat the process. I eventually got it into the boot loader and I noticed "based version: N/A" I'm not sure what that means but I hit start and now all it does is get stuck at the multi-colored X logo.
Getting back into boot loader I tried recovery mode, the response is "No command". Tried plugging it into my PC and I get the little (ba dum) sound but no device or folders to be scene.
I think i'm in trouble. I wanted to see if I could root it just so the device works again but I can't access it on my PC.
Can anyone think of a step or process I forgot to try?

My Nexus 7, wont turn on anymore either i charged it , it was very low went down to 11% battery so i turned it off and charged it, saw the battery on the screen and now.. It will not turn on, unit feels very warm when charging. It started to lag a bit , before i turned it off.. its normal software as supplied by nexus. so..> no matter how long i hold the buttons.. its off and screen stays black..
doh....asked for RMA number..only used it for a month

My Nexus 7 32Gb won't turn on either. I've been having since I got it the battery has been showing 0% since I turned it on. Regardless of how much charging I did it never changed. It ran fine and was told it might be to do with calibrating the battery but it then started to have problems turning on. It's gone off and I've tried the various power on options mentioned in this thread and nothing is working.
I guess it means a return to Carphone Warehouse. I had just got it all set-up as well.
I had rooted it and manually upgraded it to 4.2.1. It was running fine bar the 0% battery issue. I did the same thing to my Mum's 16Gb Nexus 7 and no problems at all with that one.

Hold the power button for 10 seconds or more.Happened to me just yesterday.
Plugin Nexus 7 does not bring up the charging animation.But after holding the power button for about 10 seconds,the boot animation finally appeared

New Nexus 7 Died after 2 Hrs Use
Nexus 7 shut off after only 2 Hrs of use and placed on USB charge. Tried holding button down for 30 Seconds and up/down combination with Power and nothing worked. Opened back cover carefully and patiently with Plastic Opening Tool I already had. Disconnected battery for thirty seconds then replaced connector without removing battery. Snapped cover back on. Hit power and it turned on. Do not use metal on case to open. Hope this helps. I got the idea from Youtube Video. I'm a new user and Not allowed to post links yet. Nexus 7 Teardown Review.

Thanks a lot I holded power button for more than 15 sec it got powered on thanks for your information.I am Happy now.

Man, I was just freaking out. Just got the wifi 16 on Monday. Rommed it as soon as I got home. Was using it at my local watering hole, and it suddenly just would not respond. Black screen, yadda yadda.
15 seconds of holding the power button and boom. Google logo, and then SmoothROM's boot ani. *wipes forehead* Never been so happy to see Jessica Nigri's face! lol

Thank You
I had been turning the Nexus on and off for the last couple of days, No "problems".
I tried to turn it on a couple of minutes ago and NOTHING. I even pluged it in and the battery charging icon did not turn on.
I also tried holding the button for 5 seconds but still nothing.
Fix:
I had to held the button for over 15 seconds to get it to turn on.
Thanks!

Similar problem with my nexus 7. Battery charge shows up when i plug it in. If I try to turn it on while its plugged in, i get what looks like static and lines on the screen. When I unplug it, it dies. If I hold the power button down, and plug it in, it will boot normally, and everything seems to work fine, but the battery shows as dead, and as soon as I unplug it, it dies.Just got it, it came with 4.2.1 running on it, it was an open box from Best Buy, and developer options were already enabled on it. Looks like someone tried to root it, f'd it up, and returned it. Guess I'm taking it back and returning it as well. Just a major pain as it's 1.5 hours each way from where I live to the closest best buy and back.
My problem is an easy fix, return it. However, I'd like to know if anyone figures out a fix for this incase it happens in the future.
Thanks.

Stupid stupid mistake!

I think I have fried my Nexus 7.... didn't even think about what I did how stupid am I....
I decided to wire up a Hella connector to a USB cable the idea being to plug it into my phone for charging on the road... I then had a not so smart idea to use my OTG cable to connect the USB A connector to my Nexus 7 to see if it worked...
Nexus 7 booted past the bootloader and then nothing.... I realised then how stupid I had just been...and still nothing...
Presumably I've run a shed load of power down one of the data line..... what a fool.....
ARGH!!!!!!! anything I can possibly do to salvage it.... please!! :crying::crying::crying:

you could try something ASUS support told me, press all buttons (volume + & -, power) for 30 seconds, and if it won't boot after that, you should get a RMA

Going the RMA route would be costly. If it is dead, he'd be better off just bring a new N7.

Thanks for the suggestion but no it hasn't worked...
I've had the N7 plugged into the charger for the last 30 minutes or so and when I went back to it the screen backlight was on slightly (you can see if you look at the screen from the side)... but the whole unit was really really hot... I've obviously disconnected it but now can't get the thing to turn off, if I hold down the power button the screen flicks off but then back on.

I would think that "broken display” units on eBay/CL probably have working mobos and batteries, as the owners are trying to dump them because of the broken screen. But, buying used is a crap shoot.
Nice that Google is selling N7s at cost (or even a loss) - but it does mean that any oem component replacements will be a significant fraction of the original price.

I was reading in Play Books when my N7 shut down due to low battery. I plugged it in and it wouldn't charge or boot and I noticed a faint light bleed and faint dots streaming from right to left on the display. I tried things like holding the power button for 30 seconds to reset, holding vol down and power to try to get to recovery, but it wouldn't take. Finally, with it plugged in, I held down the power button for just about 10 seconds and backlight and dots stopped. A few seconds later without pressing anything, it booted up. It would start to charge, but if the screen timed out, I was back to the earlier state and it wouldn't come on. So I got it started again and immediately went to developer options and checked Stay Awake while plugged in. Eventually the charge built up and I'm back to normal, at least my N7 is normal. I only mention this because the OP talked about the faint backlight and it may be worth trying.

A standard hella charger outputs 5V at 2A which is the same as your N7 original wall charger.
I doubt your problem came from the charger, it might be softbrick at an unfortunately moment.
I came across a similar problem when i was editing a custom kernel.
If you tried every method to shut down the device and failed do the following:
1. Open the case (it's quite easy to open with a plastic card)
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
2. Unplug the battery and hold the power button 30 seconds (with the battery detached)
3. Let it soak for 10 minutes
4. Reconnect the battery and close the lid.
5. Put your nexus 7 in the wall charger, and you should see the battery bar on the screen.
After that, let it charge a few minutes and boot the device.

Nexus 6P WILL NOT power back on

I was customizing a widget on my phone when all of a sudden, it freezes then crashes and powers itself off. It then proceeded to power itself back on but took more than 3 minutes on the colorful Google startup animation screen, which I thought was way longer than usual, so I held the power button to shut it off and start it up. But the thing is, it didn't start back up. I held the power button for 5, 15 seconds, 1, 10 minutes, no response. Power +volume down button for 15, 30 seconds, 1 minute, 5 minutes, nothing. Plugged into wall and computer for 15, 30 minutes, unplug and plug back in after 5 seconds and hold power button, nothing. Practically all trouble shooting tips had solved nothing. Not even a single week had completed after this phone was initially powered on before it did this. I contacted Google support and after they had guided me through the same tips I had already tried, they told me they could not assist any further because I had purchased it from Amazon. I got it unlocked and used a SIM card from Consumer Cellular. Huawei was closed so I sent an email explaining the problem. I want to get this fixed without sending it back, but chances are I will just send it back to Amazon for a new one because I heard Huawei takes weeks to do so, that is after I get back from vacation. The greatest time for your phone to brick on you, the evening that you arrive to your week-long vacation destination, right? I had spent about $30 on a skin and a screen protector for the phone already and had put them on, just so I can send it back less than a week later. Really cool. Is there some dark magic trick that I am missing here to get it rebooted? Has anyone else had this specific problem with the 6P? What do I do?

Can you hook it up to a computer

stupid question. but did you plug it in to the stock charger/cable. if so did any kinda charge light come on?

Sounds like a hardware problem to me, perhaps like a loose module or something. You should get it replaced asap

Yes I was using the stock rapid charging adapter and cable for wall charging, and I used a third party cable for the computer, both techniques did not work.

That's what I'm thinking I'm going to have to do, I'll have to do it through Aamazon. I'm on vacation so do you think I'll be able to ship it out and get a new one from our rental house address by the end of the week?
