Completely discharged battery? - Nexus 4 Q&A, Help & Troubleshooting

What we had:
Nexus 4. with cracked digitizier, but finely working. (except the battery, which lasted less than it should) i tried to remove glass, of course with no luck. Ended with no image on lcd. but phone worked fine, charged, connected to pc, played sounds, etc.
2 weeks of waiting for new lcd. I didn't charge it all that time. (my bad)
So after replacement, i tried to power on, aand it didn't show any signs of life. Put it on charge, red led blinked once when i connected usb. (there was no red led any time after "first charge")
So now:
When i power it on without charge it gives one short vibration. No led or image.
When i put it on charge no reaction at all, but when i hold power button it gives the same vibration and if i hold it for 8-10 seconds more the red led blinks. It stops blinking only when i release power. Also, when the red led blinks, strange repeated noise comes from charger.
Also, i'm not sure about lcd, but it should be fine. No reaction from pc, also.
Your ideas? Hoping it's not the motherboard fault

Take the back off again, unplug the battery and replug it. Then try to boot/charge (you can do this without replacing the back, in case you want to try again). If this doesn't work, you may need a new battery. Most likely the battery itself is fine, but maybe the connector ribbon was damaged.

Notification LED red.....MDA dead

Help....seems that my Magician is dead....making a long phone call (1 h) after call end, display switch off and Notification led become fix Blue (bluethoot was off) and then i try to hard reset. Led switch off and no results. I try then to put the power supply cable and the led become RED.... !!! (neve seen red.....) pda is not switching on anymore...any details on the reason of this RED light ???....please.....
thanks in advance
Red LED means the battery isn't connected or the device can't charge.
Try taking the battery out for a few hours and try to switch the device on again.
My brother in-law had the red LED issue too, we solved it by 'kick starting' the battery with two wires and a 9v battery. (At your own risk of course).
Good luck!

Red Led doesn't mean that the battery is not connect with the device. It simply means the cover is not properly intact. Try taking out the battery off the device, put it back in the slot. Place the cover carefully and completely. And then connect the device to AC power supply. It would definitely come *alive*
still dead....grrrr
so cover is ok...it seems to be properly fixed, even the smal swithch that create some unwanted crash few months ago is now working properly...
i made a 1 h long phone call with battery and charger (usb from pc) and after line felt down, bluetooth led blue on (was off) and screen with phone but no changement by touching it. so switch off by power off and ...dead...now without battery but with charger (or usb from PC) RED led on. With batttery AND charger RED on, and with battery all dead. i cannot reset anyhow with or without battery /charger....need it...sh*t.....(ops...sorry)
thanks a lot anyway....

what I will suggest is, you should get a new battery instead!!
Got the same problem now!
Both my wife and me got a Magician. Hers is dead now - same symptoms.
First guess was dead battery as well. But I exchanged it with mine fully loaded. No difference!
Usually when you plug the powercord into the device orange flashes up and device boots. Here nothing happens.
I'll have some electrician have a look at both. Maybe he can find the fault by comparison. But I don't expect a lucky outcome.
on back side of ur device when u remove the battery cover, u see a small black switch on the right side just next to the battery.
put the device on charge..with cover off---it will show red light contunuously on.
now manually press gently that black switch and see if ur device starts to charge.
if u see a yellow light any point of time doing this u may have to get this little switch repaired or do a temporary work urself by kepping it at place manually bu something.
try and tell
Now it works!
I think we all knew about that little switch. But thanks for your thoughts.
Anyway, hers is running again!
Two days ago I took it fully apart. No obvious fault noticeable. I left it the way it was now to prepare it for shipping. Today my wife asked me I should try it just once again. So I held the battery on the connector and plugged the USB cable and then: it booted!
But the internal battery doesn't seem to recover. It stays at 0% (1h "charging" since then).
I have to correct myself: Even the internal battery is charging (but it takes its time).
my magician is also dead and just the red LED is burning when i put it in the USB! Can anybody help me?
Still ned solution!
Can some one who was having the same problem help?
your device battery detector switch(little switch) is broken or logged-out of Main Board.
when it broken,the red LED is on at all.
it is the greatest weakness of magician...

Flashing red led of death

Hi everyone, yesterday I took my G1 from my pocket (after using it normally for some hours) and it was turned off. I thought the battery was dead (I left it at about 20% charge) so I tried to turn it back on and surprise...no vital signs at all. The phone didn't turn on, and the led was dead. After losing half of my hair, I tried removing the battery and placing it back. Now the phone behaves like this; when I press the power button, as long as I keep it pressed the led flashes red and that's it. When I stop pressing the power button the led stops flashing. When I plug the usb cable, the led gives a solid red and stays like that forever.
Please someone tell me it's just a screwed up battery...please

Probably bad battery. It is certainly worth it to at least try another battery -- they're dirt cheap anyways, or better yet, BORROW one.
* Solid green (when connected to the power adapter): The battery is fully charged.
* Solid red (when connected to the power adapter): The battery is charging.
* Flashing red: The battery is low and needs to be charged.
* Flashing green: There is a new notification.

Leave it to charge for 30 minutes or so, then try to power on. should be okay
better to charge from ac power if u can
Its possible your charger could be faulty.
I have the same problem, has anyone found a solution?
Try leaving it charge for a good hour, or just go out and try a new battery, could just be dead.
Sent from my Xoom
sometimes if a battery gets to low it wont even charge... not just for phones but cameras too and so on..... iv had to do this to cell phones and cameras.... take a usb cord you dont care about and cut it and expose the red and black wires..... look for the positive on your battery and negative, usually its marked, how positive to positive and negative to negative for 30 seconds to a minute while its plugged into the computer then, pop the battery back into the phone and try to charge..... everytime iv had to do this for a freind or something of my own the battery has lasted over a year after with no problems.... just a suggestion
Thanks for the suggestions. I had already ordered a new battery and the phone boots up with it but it won't charge on or off and usb isn't recognized either. I tried wiggling the plug around to see if it was some kind of loose connection but it doesn't appear to be the case. I may take the phone apart and see if anything is loose but otherwise I'll just have to enjoy the last 30% battery of G1 time I have.

[Q] Please help Droid X won't turn on when pressing power buttom

I turned my DX off for a few minutes and now I am unable to turn it back on. I hold the power button and the screen remains black, no M logo no boot, no green LED light, no activity of any kind, just a black screen.
Battery was at 100% when I turned it off ( 20 minutes ago)
GB leak rooted working fine
Tried: Pulling battery, holding power and home buttons then the camera, volume down and power buttons with no response of any kind.
Please help.
Hold down both volume keys power and home key until you see a brief flash, then let go, can you get the bootloader screen to show up? Have you pulled the battery?
It did not work.
I pulled the battery and left out for a few minutes with no results.
I also remember that before this thing happened when I pulled the battery and plug in the wall charger the screen would show a battery icon with a question mark, now I got nothing but the black screen.
The only response that I have noticed when trying your tip is that without the battery when i plug in the charger the green led blinks once.
I am starting to feel that this is hardware related.
Keep the battery out. Plug in the WALL charger, not through USB. (yes, I know it's a USB cable that goes into a converter to use an electrical outlet; the point is, hook it up to an actual electrical outlet)
If you don't get the big battery indicator for charging coming on the screen, hit power once. Still not, hold power down a solid 5 seconds. If still no go, then you have a hardware problem. Also, try using a different USB cable just in case if this doesn't work.

I just tried your instructions by the letter and on top of that I also used a straight (non USB) charger. No response.
I have a dead fish that is going back to the store.
thanks for your help

[Q] Blinking red led, no boot when plugged in

Hi all,
My Nexus 4 just shut down after going really hot. I cannot turn it on anymore, when I press the On/Off button with our without the volume buttons nothing happens, except if it is plugged in.
In that case, after about 15 sec I have a blinking red led.
I think the problem is material, but I don't know if the problem comes from the battery or something else. I don't want to buy a new battery if my Nexus 4 is dead... So I am trying to figure out if the problem is about the battery or not. I think not because even when plugged in, nothing shows on the screen when I try to turn it on.
What do you think ?
Thanks very much for your help,
Guillaume.

When you get the blinking red led while on the charger, how many time does it flashes ?
Is it the same as this:
"
By red flashing light, I mean: Hold power for 12 secs with good charger connected gives flashing red light: one short, pause circa 2 sec, 11 flashes at one per sec, pause under 1/4 sec, one short dim flash, pause c. 2 sec, repeat. This is the notification LED directly above the USB socket.

Hi cxda48,
I have the exact same behaviour : 11 flashes, a short pause followed with one short flash, then repeat.
You have an idea of what it means ?
Thanks !
I had a similar problem. The phone will not start and when you put the red light blinking loaded several times. My Solving: I opened the phone and pulled the battery pins. I connected the battery and the phone started normally.

*similar* but not the same I guess.
It seems like the IC that turns on and off the LED is the PMIC ("Power Management Integrated Circuit"). When something goes wrong, this IC has got some intelligence to give out some information about what is wrong (a bit like the bios on a PC). So 11 red LED flashes is an error code I guess. When the battery is disconnected it's 1 red LED flash (that error code probably means battery not present/worng) in my experience.
I know at least that with the 11 flashes issue, changing / reconnecting a charged battery does not solve this issue
Would anyone have information about what these codes mean ?
this just happened to me. Any solutions?

I thought I should give some feedback on how I sorted out this problem:
After discussion with google after-sales, I sent it for repair to the official LG repair contractor in the UK (SBE Ltd, based in Ashford, UK).
I precisely chose to go through LG repair rather than google because google warned me they would replace the nexus4 so I would
1) loose my data
2) get a potentially worse phone(refurbished) than mine (which is really mint with outstanding battery life)
I sent the phone with instructions on what I think needed done : replacement of the PMIC and *not* a swap of motherboard. When the nexus4 was back, I noticed they ignored my message & swapped the motherboard .
They kept my housing but they also swapped the battery(was not required) and now the battery life is very poor ! I am still in communication with LG regarding the battery issue

Won't switch on, or off...

Hi all. my Samsung S7 Edge was working fine albeit a bit sluggish at times but it was okay. I was down to 14% charge and so connected it to its Samsung charger with a non stock cable which is its usual charging process. It was otherwise okay and the screen went off so it was completely black, the red charging LED came on and I left it like that for a little while. It is still in that precise state and no sequence of button pressing for any amount of time gets any response at all. Nothing, no vibrate, no charging indicator, no flicker - absolutely nothing changing. Red LED and blank screen, no response. I would like to discharge the battery asap and have clamped the Vol- and on/off button pressed for 20 minutes and it is not connected to anything. It is not rooted and there is no response if I connect it to a computer. Is it bricked? How can a phone 'brick' while working as it should?
So I removed the back, disconnected the battery for a minute or so and reconnected it. The red light had gone off and now nothing, no light at all and it is connected to the charger with the Samsung cable. I have tried a different charger - my laptop. I happen to have an unused battery I was going to replace this one with so I have now also tried another battery. The phone is just dead and no response at all so I guess there is only one option - bin it!
Well I happened to have a smashed S7 Edge so a working motherboard which I replaced and obviously cured it. Restoring as much as I can remember but can anyone still suggest anything I can do that may kick start this motherboard?
The same happened with my S7 Edge, yesterday. Just a blinking blue led and I couldn't turn it on. So I waited till the battery was empty and tried to recharge it. No red led no button combos are working, nothing. The phone is dead.
Was there an update?
