[Q] Help with DVP - won't turn on

Hello. I created this account so I can finally ask some of my questions regarding this phone. I've had it since the January 6th shipping, and it's really been fine for the most part. I've the 8 gig version.
Anyway - within the last few weeks my phone has been refusing to charge on random occasions (it's really very random as to when it will charge and when it won't) - both plugged into the wall outlet via the USB power converter that came with my phone and plugged into my computer.
It's been pretty annoying, but nothing I couldn't work around. It would charge eventually.
However, last night I plugged it in to the outlet and it made the noise confirming it was plugged and started charging. This morning, I unplug it and it's non-responsive. It doesn't respond to anything. I have tried:
-turning it on with the power button; holding it down for an extended period and releasing
-taking out the battery
-plugging it in to my computer (which didn't recognize anything being plugged in)
-plugging it in to a different outlet with a different cable (phone came with two)
I've let it sit plugged in for three hours now and retried all of these things and still nothing... it's dead!
I'm not sure where to go from here? I guess I should have my husband call Dell.
Has anyone had any trouble with the sporadic charging?
Are there any solutions I've missed to get my phone to turn on?

You say you've let it sit for a while, was that plugged into a power source? Try that, it sounds like your battery has gone completely flat and probably needs to sit on a power source. Failing that definitely call Dell and get a replacement battery and charger and see if that fixes it, sounds like one of those items is your problem.

Yes, it has been (and still is) plugged in that whole time. I edited my post
Yeah, something is wonky, I just cannot pinpoint it. My husband's will sometimes not charge, too. But, much less often than mine does.

charging issues
In the last 2 days my VP freezes while charging overnight. Restarts when I take out and replace battery. It will also freeze when I try to use any app while charging. I tried to use Dell chat to resolve issue but got bounced around. I even had an agent tell me my service tag wasnt valid. I'll try to call 800# when I have a free hour or so (I'm sure the call will take that long). The first two levels of support at Dell seem to have no clue regarding the VP it's very frustrating. P.S. what happens with all the apps I've purchased if they need to replace my phone?

Have you swapped batteries with your other DVP? Maybe replacement is the only option, hit up @dellcares on twitter, they have helped me in the past and bypass the whole waiting on hold nonsense with dell mobility.
@tbvnz: all your purchased appls will be reinstalled automatically if you installed them via the Zune software on your pc. The ones installed via the phone can be reinstalled from the MP on the phone, just hit the Buy button again and it will tell you its already been purchased and allow you to download it again.

Update:
I snagged my husband's battery and put it in my phone. My phone immediately came on and is now functioning. My computer recognizes it as being plugged in and it's charging.
And, my battery in my husband's phone works fine. It is fully charged and his phone is having no issues.
Certainly this is annoying (and did in fact happen to my husband a few weeks ago where his phone wouldn't respond until MY battery was put in his phone, but we chocked that up to the battery being dead {which it was}.) but at least my husband and I both have DVPs and can interchange batteries... I wonder what someone who didn't have that option would do.
Certainly confusing that removing and replacing my existing battery wouldn't turn the phone on, but my husband's would - even though both batteries are at full charge.
Thanks for the help! I'm not sure if I should contact Dell about it or not. Clearly it's subpar performance, but I've not been completely impressed by this phone in the nearly two months that we've had them, anyway.

Good to hear you are up and running. You could keep an eye on the situation and contact Dell for a replacement battery if it occurs again.

Thanks. Yep, I'll contact them the next time it happens. Anyone else had this problem??

My brother and I have experienced the same behavior on both of our phones. Most recent was his this past week, exactly as you described. It would not turn on via the power button, so I swapped his battery with mine and his booted right up. When I tried his battery in my phone it showed a full charge. That has happened to me one or two times, randomly.

I've seen that behavior in my DVP (picked it up two weekends ago) and I can tell you how to work around it.
What seems to be happening is some kind of bug when you have it connected and charging and try to turn on/off the phone. If you notice, when it seems unresponsive, the hardware keyboard will probably still light up. This is because it's actually on but the screen just doesn't get any output/input.
What I did was this:
1. Disconnect your phone from the charger.
2. Slide the hardware keyboard down so you can see whether it is lit up (on) or not.
3. Hold down the power button until the exact moment you see the keyboard go dark (off). You have to be quick because it will try to turn right back on a few milliseconds later if you still have the power button depressed, leaving it still non-responsive.
4. Wait a few seconds, and press the power button as normal to turn it on. This time you should see the Dell logo, etc. and everything will be fine.
I've gotten into the habit of either leaving it on or turning it off before I connect it to my charger (it's my alarm clock so it's on almost all the time).
Hope that helps.

my DVP won't turn on either...
Hi - i'm glad i found this post because i've had my DVP for 3 days now and its frozen about 5 times and this morning wouldn't turn on or seem to take a charge. it was fully charged when i put it down last night and this morning there was nothing.
i've stuck it into a wall outlet for now and i guess i'll just wait for it. don't know what else to do. don't know anyone else around with the same phone, so that battery swap isn't an option. pretty funny that you realized to do that and that it worked.
anyway, i feel better now that i've complained about it. thanks.

Did you try pulling the battery and then booting it up? If that doesn't work, after a pull just leave the battery in the phone and let it charge. After 20 minutes you should see it power on.

So it's continued to happen with my phone whenever I have it plugged in to the wall with the brick that came with the phone. Annoying! Basically I cannot have it plugged in next to my bed; it can only charge on my computer. So much for using it as an alarm!
I will try the power down and reboot with the keyboard out. I know what you speak of with the flashing keyboard. I hadn't tried to see if mine is flashing while the phone is 'dead'.

[Q] Didn't even flash or root yet and my 32 grey GT died last night...

Didn't even flash or root yet and my 32 grey GT died last night. It had been working great and was getting ready to flash pershoots kernel this weekend. Last night I plugged in after shutting it down like I do every night. Today when I went to turn it on nothing. I tried holding down the power button for a while and still nothing. I tried holding down volume buttons with power for extended period still nothing. I even tried plugging into different outlet to see if something happened with outlet and maybe drained the battery overnight. Luckily I got it from Fry's two weeks ago on Friday right when they came out and Fry's has a 15 day return policy but this makes me a little concerned... and that's cutting it a little too close.
Has anyone heard of things like this happening with the GT? I'm thinking I may need to see if they'll still sell me the extended warranty. I babied this thing and hadn't even flashed anything on it yet. I'm a little concerned about the reliability of the hardware... I'm not usually the one with the needle in the haystack device that goes bad but who knows... I'm already in withdrawal without it.
Is there anything else I can try before I take it back? Maybe try plugging it into the computer instead to see what happens? I can't really see what else I could do since this thing doesn't have a removable battery. If it won't power on I can't imagine there's much I can test with the SDK dev tools from the PC using the usb cable?

plugged it in with usb...
I do hear the sound of a device being plugged in on win7 when I plugged GT in and got the driver message in tray. GT still won't turn on. When I hold down the power button every about 6 seconds my windows machine machine makes the same sound you get when plugging in a usb device in addition to an extra sound at the end.
[email protected] well I guess it's going back tomorrow.

You got the sleep of death. This is a honeycomb bug that i have personally experienced in the xoom, transformer, and the GT. The way to fix it is to unplug the GT, press the power button down by itself and hold it until the you see the screen turn on and startto boot up. It may take 15 seconds or more.
If that doesnt work, plug it into the wall outlet and try the process again. If that fails also, unplug it again and try the process once more.
That combination seems to work for everyone. The only exception would be if the battery is completely drained. You would need to plug it into a wall charger for a few hours and let the battery charge, and then try the process again.
I dont know why this hasnt been fixed by google yet, its really annoying. I thought 3.1 would fix it but it didnt.

you should have post this on the general thread, but why dont you return it for a different one? problem solve...

Android Development is not for your Questions or Problems Please post in the correct forums
Moving to General

I think you got the battery drained .. for some odd reasons the android has leaky power consumption even when shutdown on occasions ..
Charge it up for a while .. wait .. correction LONG while ..
Hope that is the problem

Exactly the same problem, I have tried the hold power button but it is not working... any other work around?
Please Help

I chatted with a rep from Samsung last knight and he told me that I needed to leave the Tab charging for at least 6 hours and then try again... so I'll let you know if that did the trick... hope it does...

I've actually had this happen on two different 32GB Galaxy Tabs (the original one I purchased and its replacement). After powering the device down it would not boot up.
In both cases it happened about 3 days after receiving the tablet and with 80-90% battery charge remaining. I tried additional charging, holding the power button down for an extended period of time, and attempting to boot into download mode - everything failed to bring it back to life.
I'm not sure what triggers this condition my only suspicion was that it may have something to do with enabling encryption on the device. On the second tablet I didn't have time to do much customization or install many apps but it ended up dying shortly after enabling encryption.

Wow. This happened to me yesterday with my 16gb from Sprint. Had come unlocked,yesterday 3 days in, died. I tried all the suggestions above to no avail.
Took it to corporate today. Now waiting on replacement.
bumming*
Hope next one is unlocked
Edit**** worked. Lol. Guess I didn't try it again today after I tried charging it last night.
About 15 to 20 seconds and she's back!!! Excellent! ! Thank you so much.
Not sure now whether to replace it.
With another.

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.

[Q] Yet another Nook not holding charge and hanging at the boot screen

Google shows me I'm not even remotely alone in my trouble, but with the way tech works every problem is at least a little unique. I'll give a rundown of what I've down and whats happened up to this point.
First, I bought it used from Amazon. Very Good condition from a seller with 99% or whatever satisfaction. I think I've bought from them before, actually. So while this isn't a new device, I know I wasn't scammed. It was also factory reset and I'm assuming it wasn't rooted, though admittedly I have no idea how to check on a Nook.
Second, when it arrived the first thing I did, naturally, was turn it on. Plugged in the Nook to my computer, it booted up just fine, I registered, and loaded one a few ebooks with Calibre. The books opened up, they looked great, we were golden.That was when I noticed the battery indicator in the top didn't have a number on it. It was solid black with a ?. I thought that was weird, so I tried rebooting the device. That was when I was hit with an update, it downloaded and installed then rebooted. Here's when it all went to crap.
Third, I can get into the device. If I hold the power button and wait a bit it takes me to the homescreen where I'm met with a 0% Battery warning saying to plug it in or the device will shut off. Waiting for this message do disappear seems to give me normal access to the device, except the battery indicator is still just ?. This still happens now, after about 10 hours of charging.
Fourth, plugging in the device to anything be it wall charger or computer causes the device to reboot back to the Read Forever screen. Even if the device is completely powered off. It just hangs at the boot screen and goes nowhere. If I hold down the power button, or power + n, all it does is flash the screen to blank and then goes back to the boot screen. If I unplug it and hold down power it goes back to the previous problem.
That's everything I know. I seem to have the proper Nook micro USB cable, but the adapter is a little white Chinese looking thing so I know it's not the official. So I've switched to my Nexus 5's micro USB cable since I know it works and plugged it into my PC. The charging indicator is on, but thanks to my minor colour blindess I'm having a hell of a time deciding if it's orange or green. It's either green, orange, or yellow for sure though. Right now I'm going to go to sleep, let it charge through the night. I've had a similar problem happen to my Nexus 7 where it wouldn't turn on, and a nightlong charge seemed to fix it so who knows, this thread might be useless in the morning.
In the more likely event that it's still very useful, any help would be appreciated. And please try to keep it simple. I'm not new to technology or Android in phone/tablet form and all the associated hairpulling, but this is literally the first time I've ever dealt with an ereader. I'd like to get this solved at home, since I don't have a warranty and the price to ship this thing back to the seller would make this end up costing more than a new one would have since I'm Canadian and the seller isn't.
Thanks in advance.
Edit: After a night of charging, still 0%.

This, unfortunately, is the sign of a factory buggy (for lack of a better word) device. I doubt there's any hope. Sorry about that.
Keep me updated.

I think that there might be software to blame. My Motorola Defy also had that sort of weird battery behaviour after one of factory resets. Since then I have to install a patch written by one of XDA members every time I make a reset. But it works. Unfortunately I have no idea if it can be helpful in this case. (I'm refering to this post: http://forum.xda-developers.com/showpost.php?p=34590229&postcount=1 )
Nonetheless I would seek some slight hope in disconnecting and reconnecting the battery.

Alright, so. Progress report:
I tried the 8 failed boots trick to reset the device back to the original firmware. This brought me back to square one. The device worked, I could load books on to it via USB, and read them. But the battery indicator was just a question mark. Going into the settings revealed that the battery was at 100%, or at least claimed to be. But hey, I could read on it so I figured I was alright.
Now, a couple days later, I just woke up to find it with a new problem. Pressing the little N button to wake it up isn't doing anything. It won't respond to holding the power button down and my computer wont pick it up when it is plugged in. The charging light still comes on but I don't know how much it can be trusted.
I'm going to let it charge for a bit, but I'm beginning to think the battery is just toast.

Hi, I just went through something similar 48 hrs ago. The NST is frozen, stuck at reading forever. Before that, the battery icon had a '?', and the device info said battery status was "unavailable". Plugging in to charge had a solid green light.
I read around, and what worked was to open the case, and disconnect the battery. Google said to wait 30 mins, I waited 1. Re plugged in, put it to charge. The LED turned to orange, and 15 mins later, the NST booted. All good now.
Total cost: set of TORX scredrivers (you need a T5).

Okay, so. No T5 but I managed it with a teensy weensy flathead. Unlugged the battery, left it that way for about 20 minutes, plugged it back in, then left it to charge. 15 minutes later I came back and viola, it works and the battery is reporting it's remaining juice. Thank you very much, that seems to have done the trick.
You know, this might be the first time I ever managed to have a tech problem solved entirely by a forum.

It's a used device, there was never a warranty.

Looks like the problem is fixed. Great! Sorry I was inactive.

[Q] N4 doesnt turn on. Red Light blinks once.

Hello.
When I try to turn on my N4, I hold power button, and after about 10 seconds Red light blinks (just once, if it's connected to USB that 1 blink last for 3 seconds, if connected to wall, it's just quick 1 blink. If it not connected anywhere there is no action at all, it just stays dead, no blinks, nothing). Same if I try to go in bootloader by holding volume down+power.
This happened after I successfully installed CM12, with no errors. Then I rebooted my phone, and it just stayed black as it is now. Battery was around 25~30% that time, and phone was connected to USB.
Did I bricked my phone totally? I am now trying to charge it up already for 1 hour... but it nothing changes.
I have searched here for similar problems, but couldn't find solution...
Edit: Charging already for 10h+ , still same..
Edit2: I removed battery, reconnected after a while, still same problem.
So I tested it with multimeter, it says 2.6V, but fully charged must be 3.8V. Could this be a problem? I was charging it for whole night.
Edit3: I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...
When I connect to PC usb, there are unrecognized deviced called "QHSUSB_DLOAD".

easy fix
Hold down the power button and the volume down button at the same time until phone reboots. If you see the little android no need to worry just let go and wait for your device to reboot on its own. This is not a factory reset it's just like restarting your device. :good:

I have tried that many times. Nothing. It's bootloader screen, but I can't get there. Nothing happens. If I keep holding volume down+power it just keep blinking once every ~10 seconds, same if I hold just power button. If phone is not connected to charger, there are no blinks at all.

I removed battery, reconnected after a while, still same problem.
So I tested it with multimeter, it says 2.6V, but fully charged must be 3.8V. Could this be a problem? I was charging it for whole night.

I had the same problem a year ago, I tried to remove the battery, charging all night, and other solutions that I found online and no one worked.
Finally I found here in XDA a user with the same problem and his solution was charger the phone with a wireless charger, a friend of mine has one and I put the phone to charge and after a few minutes the screen goes on and the phone was charged, then I press power button and the nexus run again.
Hope this works.
Sorry for my bad English, I'm from Spain.
Good luck.
(I bought a wireless charger in case it happen again)

I don't know anyone with wireless charger. I already ordered a new battery, and then I probably will get wireless charger also. Ty.
But this problem is very weird if you think so.. I think it happened because of many aspects together:
1) Battery was already below 30%
2) I pretty regularly charge phone with USB (won't do it again)
3) It was connected to PC USB in same time.
4) I installed CM12 ROM in same time
So main reason I think is USB, that I restarted phone while it was on pretty low battery and with USB connected.. phone restarted and got invalid voltages and couldn't even boot up or charge phone. I also found an article which says, minimum voltage, when phone battery has 0%, it's 3.0V, so I was below that.. it just screwed everything and battery died. Well, I am not sure for 100% that it's battery fault, but I hope so, I really love my N4 and still wanna use it for long time, I hope it's not dead phone, just a dead battery. Lets see! I will update this thread , when I get my new battery (less than month probably).
Sorry, my english is also not perfect. I am from Latvia.

I was playing when it happened to me. The phone was very very hot and the battery was around 70%. When I put in the wireless charged and I can reboot the phone the battery was at 65%, so it had charge but the phone won't boot.
I charge my phone almost every day, sometimes with AC, others with USB (plugging to PC) or wireless that depends of my needs
I hope you can fix it. Good luck.

Btw. Do you know if battery charges with wireless charger, if it's removed from the phone?

Don't think it does, since the receiving coils for wireless charging are located just behind the glass back.

The battery will charge with a NCF Charger
Major Issue Google
This "Nexus SOD" issue is showing up on many sites across the Internet. I have multiple "Nexus" devices including 2 Nexus 4, 1 Nexus 5, 2 "Nexus 7 2013". It suddenly started out of the blue with one of my Nexus 4 phones. Symptoms included rapid battery discharge. I am using Lollipop 5.1 on all devices. There are many claims as to the cause, Hardware Motherboard, Power Button etc. Others claim it is "Software Related" or App Related. The problem effects Nexus 4 and Nexus 5 phones. I have ordered a new motherboard for my nexus 4 device and see if that makes a difference.
This problem should warrant a "Major Android Lollipop Crisis Team" by Google to investigate the cause and let us know what it is and what Google is doing to solve the problem before moving to announce "Android M". This issue needs to brought up and actively pursued at the upcoming "Google I/O Conference" by the strong Android Developers Groups to press for "Formal Action"

I had this problem a long time ago and my fix worked for me after doing a little research it seems like this is a case called battery total discharge. The fix was simply to charge your phone using the wall adapter that came with your phone (I still use my old apple cube wall thing) and to wait for the red light to appear then wait about ten minutes before trying to reboot.

I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...
When I connect to PC usb, there are unrecognized deviced called "QHSUSB_DLOAD".

Maybe this video will help you: Oh I´m not allowed to post links until now.
Just search for: - Nexus 4 "red light of death" fix - at youtube.
Hope it will help

I have checked all kind of videos there. Also that one. Most of these cases are related to battery, but it seems in my case it isn't. I just searched for QHSUSB_DLOAD unrecognized device, all posts says it means phone is bricked... But cmon, how? I installed CM12, successfully, without any errors, then just restarted phone, and its dead...

Did u try booting the phone without battery by connecting to wall charger and what about flashing stock ROM via PC
Also check that the power button works
This case should be solved

Just tried booting without battery, and connecting to wall. Same - red light blinks once, after I hold Power button or Power+Volume down for about 15 seconds. If I keep buttons pressed, it just repeats every ~15 seconds.
Power buttons works fine.
After I checked that Device manager thing in google.. it looks very bad.. phone is dead.. probably need to change motherboard. I am just shocked, how this could happen... I didn't receive any errors during CM12 installation. Phone just instantly died after restart.
