Dell Streak won't start

Yesterday, before going to sleep I checked my mail and layed my phone next to me. This morning I grab my phone but it doesn't respond. I just charged it for an hour but still no response... Any suggestions

Remove & install battery, then boot up again?

I allready did that twice without result but after reading your reply I tried again. Now I replaced the SIM and SD card too and now it's working again! Thanks.

Don't want to bring you down but It sort of happened the same for me, I went to sleep with 85% batt, plugged the charger went to bet, next moring tried to tur on, nothing, charger was still on, tried pulling te batt out, turn on no luck. Still haven't been able to figure it out but I know my streak won't charge the battery so I'm charging the batt outside the streak ordered a second batt so no way to test cable/battery ATM, so far can't say if it's the battery but it don't look like the battery is the problem. forgot to mention, a couple of times I saw the empty battery icon, so i used a BB Bold battery to jump start the phone (just making sure the streak was ok heh), only thing I can think off is that there was a power surge of some sort and took the charging IC with it. The cable works fine for sync and x-fer files but charging is a NO go. it goes as far as telling where the power source is coming (USB/AC) but thats about it. no charge.
so before reaching my conclution i say make sure the metal contacts are touching the battery, make sure the battery has charge if you are an avid electronics guy I say check voltage on the battery and see how is that doing. I've read a lot lately to see what can be my problem and there is one tiny hope that the battery might have triggered it's security gimmick and it won't take charge the "smart" way and that is why I have to use a Li-ION "desk" charger. But I don't know that much of batteries.
I hope it guides you towards what might be happening. Not a solution but you're not alone.
***UPDATE
LOL, I realized you fixed the problem. nice one!

when you have a lot of applications running which consume a lot of battery you will notice the streak is going to tell you the charger is invalid. infact there is more powerdrainage then charging capacity. this shouldnt happen with the dell adapter which delivers 1 ampere at 5v instead of the pc which gives 500mA.
if this happens to you one time that the device wont turn on or do anything anymore unplug it from AC and detach the usb cable . then attach the usb cable to the pc and stick the other side in the device and wait for it to show desktop, should be no longer then 30 secs for it to show. (you need the dell sync software and drivers being installed)

Dell Streak 7 won't power on or off
Had my 7 for a few days now, the screen was intermittently not responding so I checked out a few forums - decided to calibrate the screen - so powered it off and then powered it back on holding the power button and the + and - volume simultaneously. Now it won't power back on properly - I just the the soft buttons lighting up. It also won't power off. I have plugged into the ac power charger and the power light does not go on at all (orange or green). It had pretty much a full battery when all this happend about 10 minutes ago.
Fixed it - buy pressing the hard reset button adjacent to the SD card slot. Now working well.

[Q] Help, Blank Screen, Backlight on, no picture

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?

I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...

Have you tried pulling the battery for a couple of minutes?

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.

You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.

Yeah that is definitely worth a shot. Just pull the battery.

Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.

I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.

How did that 'fixing itself' happened to you if i may ask? And how long did it last?

Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.

You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

Yep. Many times. And even longer than a minute.
Anyway, I'm going to contact their crappy support. Thanks everyone for trying to help.

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.

[Q] n4 is completely unresponsive (dead)

So this is what happened:
the phone discharged fully and i connected it to charge. then i got a flashing red led. seeing this as a bad omen i tried to turn my device on - no luck - it wasn't responding.
i unplugged the charger and plugged it back in and again the same result, then again..... and i got a solid red light. so after a few times of messing about with it , trying out a few sources of power and such i got it charging (the battery logo appeared). The charging lasted for ~30 sec and it went black.
So after that the n4 is completely unresponsive. No flashing leds no backlight on screen, NOTHING.i tried out a few chargers and cables and beside those i used a genuine n4 charger (it's 100% working - i tried to charge another device). i left it there for the whole day to charge thinking that maaaaaby the battery ran to a complete 0 and i just need to give it time, as you probably guessed it, that did nothing.
In fact, i think the phone is not charging at all. The reason i think so is because the wall charger is emitting a faint high-pitch squeal regardless of the fact that the phone is connected (it should be squealing only when it's plugged into socket and the phone is not plugged in it)
so TL DR:
n4 is completely dead, no signs of life. The things that were tried:
a handful of chargers and cables that are 100% working on other devices
trying to boot with a combination of volume buttons pressed
holding the power button for 60 sec. while plugged in
prolonged charging (~7 hours)
verbal threatening to sell the damned thing if it's a serious problem
so that's that. i should get my tools back from a friend on monday. i'll try to take it apart, maby there's a loose connector here or there or something. Any ideas what i could try before that?

Some searching around the forums wouldn't hurt. Try this for example.

thanks for the link, that seems to be worth a shot.... i'll be able to take the phone apart on monday, that's the earliest i will be able to try it. i was wondering if there is anything i can do until then to remedy the situation. I mean i'm really getting a kick out of my old sony erricson k300 but i kinda prefer the nexus and would prefer to fix it asap.

ok i fixed it
i used a 3v source and held the contacts manually for 5 min. that returned it to the red blinking led state and after leaving it to charge for 5 min it returned to the battery icon on screen. thanks for the info again.

Nexus 7 won't turn on

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?

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.
