[Q] Black screen but charging led lights up

Hi There,
Yesterday morning I went to work with a completely charged Moto G. When I arrived at work my screen was black and had become unresponsive.
The powerbutton doesn't wake up the phone, tried several times, holding it for more than 150sec. When connected to a charger (tried multipe) the charging led lights up, not blinking.
I have read on a motorola forum that this could indicate that there's insufficient power in the battery to activate the display.
However it was completely charged.
My Moto G has an unlocked bootloader, is rooted and has a custom rom (C-Rom, [ROM][AOSP][KK][12/05] **C-RoM** -4.4.2- -v6.5)
Is there anything I can try or is my phone a brick now?
Thanx in advance

The same problem
I am having the same problem too.
My moto G drained its battery until it shut down. Then i promptly went to charge it. The screen is blank and and notification light is on.
snooze1973 did u find a solution or is it now working?
PS My Moto g bootloader unlocked, stock rom,rooted and it is on the Faux123kernel
Thanks in advance

No luck Yet
No luck yet, left it on the charger for a whole night, still just the white charging led. No response to the power button.
But I refuse to believe it is completely dead. Before I had a HTC Desire S, tried many custom roms, never bricked it.
I just can't imagine what happend the day before yesterday.
Perhaps I'll try and find a more powerfull charger.

I think I found a solution. I followed these steps
1. Charge your phone via USB cable on your computer.
2. The white notification light should come on.
3. Then, do not touch any buttons on your phone.
4 The iconic Battery Logo(white background) should appear after several minutes.
Followed these steps and my phone eventually turned on
Good luck!!

Still no luck, trying a different cable (blackberry) now.

Not working for me, still just a beautiful white led indicator.
Start to think it's probably dead. Or battery thinks it's drained somehow.
Maybe anyone else has an idea?

Ok, I opened the Moto G and disconnected the battery, reconnected it after 10 sec. still no luck
Odd thing though and not very promising is that when the battery is disconnected the charging led still lights up when charger is connected.
Could this just mean that only the battery is fully drained or that the device is messed up?
Guess I going for a new one.

See if a new battery helps

Bought a new one today, so I can try and fix the other. First I will leave it for at least 24 hours.
Perhaps I will exchange the batteries at one time to see if that helps.

Black screen but charging led lights up
I am experiencing the same issue.
I bought a dead moto g for part replacement with my current moto g. Just out of curiosity, I plugged in the charger to the newly arrived moto g and observed the similar behavior.
To go further, I swapped the battery and tried to turn it on, and voila, it boots!! It has C-ROM. But it won't charge the battery any how. Its again back to
original behavior : No Screen, No Battery Charging, Only notification LED glows. I kept it on charger for whole night, but no luck.
The notification LED turns on even if I the battery is removed and charger is plugged in. What does that really mean?
Is there a probability that the charging circuit is broken? or it has something to do with bootloader, C-ROM and custom kernel? Does any one thinks reverting back to Stock ROM will help out in any way?

Same here...
Exactly the same with my little brother his Moto G 4G (1st gen) (stock rom, BL unlocked & rooted).
Solid white LED when plugged in, no other response.
The most advertised trick does not work (step 6: flashboot screen doesn't show up)
[SIZE=+1]Q28: Moto G will not power up (addition to Q16 and Q25)[/SIZE]
Plug it into the charger
Hold the VOL DOWN key
While still holding the VOL DOWN key, press and hold the POWER key
Hold both keys down for over 120 seconds. This is more than two minutes and will seem like a long time. You might want to time yourself to make sure you hold it longer than two minutes.
After holding the keys down for more than two minutes, release them.
The Flash Boot screen will display, and the Normal Reboot option will be highlighted
Press the VOL UP key and the device will start a normal reboot.
If you have tried the above and it didn't work, try this:
Plug in the phone for 15 minutes.
Proceed to Step 2 above.

It has been an hour on the charger of my Asus T100 Tablet (5V, 2A). Still no luck...
Due to the lack of other solutions, I guess all our phones are ready for RMA...
Update: an overnight charge on a 5V 1A charger did the trick. White led was gone this morning, booted normally.

I don't know why a USB charger and a PC connection should make any difference when the phone is not booted up.

I had the same problem. I solved it by removing the battery by opening the phone (mine was out of warranty) and taking it to repair shop where they charged the battery for an hour. Then when I put it back in, the phone rebooted normally with 10% charge.
But ever since, my battery life has deteriorated. Doesn't even last one full day. And I have had the same issue twice. I think I need a new battery.

I have a simple solution for that I have faced this issue long time ago and now I know a permanent solution. You all have usb cables in your house...just took a old one and cut it from the mini usb side..there are 4 wires...you have to care about red and black..open your moto g battery and took it off from the phone now connect the usb cable to your pc and touch the red wire to the positive and black to the negative ...just do this for 45 seconds and immediately connect the battery to the phone and connect the charger...phone will starts charging from 0 % pls do not wait to connect the switch and back cover just charge it upto 20 % the cover it up.....DO NOT LET YOUR BATTERY DRAIN MORE THAN 30% AS THIS IS COMMON PROBLEM IN LI ION BATTERIES...

Interesting, but how did you determine the negative and positive terminals on the battery flex? Can you, please, mark the attached photo of the battery of moto g to help the community?
Also, as a side note I think I discovered a solution - I connected the phone to my PC's usb 2.0 port and held the power button for 2 minutes - at which the LED blinked momentarily and then continues to shine. I left the phone connected and continued to browse for solutions to this battery charging dilemma - then about 5 minutes the LED stopped shining (and I breathed a sigh :silly: !!! becaue this is the sign of battery being charged!) and after about 30 minutes of charging I turned the phone on and it was 16% charged. Well I haven't been able to reproduce this solution (since, I have been extra cautious with the battery now!) but I would surely like to know if anyone can reproduce this solution:
1. Plug in your phone to USB 2.0 or 3.0 port with original moto g cable and confirm that the LED shines continuously.
2. Hold the power button for 2 minutes (which I discovered to be a long time if you just continuously stare at the phone!) after which you will notice that the led with blink momentarily before continuing to shine continuously. (I suggest you continue holding it for another 2 minutes after which the led will blink again momentarily)
3. Leave the power button and leave the phone attached to the port for at least 30 mins before attempting to power on.

[Q] can't boot / led blinking red

Hi all, have my xperia z3 for about two weeks, not rooted, not unlocked, without any modifications. Yesterday before sleep it was with more than a half of akku, today as im woke up and got it in my hands it was off, im plugged charging cable, was thinking maybe the battery was drained, but nothing happens still, its just blinking red (led).
Was trying to hold power + volume up, nothing.
Reset key near sim dont works for me either - i'm just notice 3x vibrations and thats it, its just repeat vibrate 3x times again and again but nothing happens, no boot.

Try to flash it with flashtool with an ftf file to the latest update and see what's happening, or just factory reset it with the pc also can be done with flashtool

Most likely the battery has drained beyond its limit Plug it in via wall and leave it on charge it could take 1-3 Hours for it to reach its limit until it will begin the charging Cycle, I recommend using the official charger that came with the phone

Flashtool seems to be not recognise my phone sadly, the only working key combination its - pressing small key near sim + power button, shortly i was able to get these vibrations by pressing power + vol. up, but its not works anymore.
Will leave phone on charge till tomorrow.

nothing happened, still blinking red being connected to wall charger whole night, might call O2.

Not 3 blinks, vibrations i mean, the led is blinking red whole time if i plug it to charger or leptop, its just , no changes at all, its still blinking same way after being plugged whole night. After my Google researches im thinking the battery drained completely off so its in a sleep mode, but i wont try to boost it because of warranty i do have. I dunno if charging dock can play some trick in this case, my bro have one.
P.S. but yea, called o2 ready and they mailed me DAT Repair retour form, just had no luck this time, will be wisely next time, but as i said last i saw it alive it was like 25% charged, **** happens.

When you press Power + Volume Up, are you still holding it after the initial 3 vibrations? I mention it because on my old HTC One X, you had to keep the buttons down for 3 sets of 3 vibrations. if you released beforehand, the phone would not reset.

Hi, as i mentioned ready, i was only able once to get vibrations by using power + volume up, its somehow don't work with my phone, maybe cause battery have very low voltage/charge. Anyhow, im using power + reset key near sim, its works always still and i can repeat it endless, its seems, till the battery will just drain off completely.
But yes im tryed 3-4-5 more resets one by one but no progress :/
Even if i get it fixed i will send it to DAT/Sony anyways, its a noway solution for the price i paid .

just for a log: got replacement - Mainboard defect. Report says they replaced the Mainboard and therefore its imei was changed, but im sure its completely new device. Whatever its working and stable, and can be completely drained off without any bs about battery sleepmod, how its was mentioned by someone on these forums. Sure this may have a place but its should be completely controlled by software/hardware, so i dont keep my eyes on the percentage of charge alltime.
At least there root nocking at the door

notification led suddenly turn on, and wont turn off

My notification led suddenly got turned on and and its not turning off. I didint apply any settings to turn it on. It keeps on, even when the phone is switched off. I tried clearing cache and dalvik cache, but no use. Please some one help me. Its been now around 12 hours.
Pls help

Unplug your charger... Should fix it.
Or if you're on a custom ROM disable it in the settings
Other wise install moto led app

Bro.. there is no charger connected. Even when the phone is switched off, the led is on. I tried the led app, nothing changes.

well than its a hardware defect. i heard it also turnes on when battery is to low to even power the display but idk,

Did the phone become wet recently? Sometime ago one person reported that after his phone was dropped in water, the led turned on and didn't turn back off. If even a factory reset dosen't turn it off now, sadly I guess you may have to send it to Moto.

Same problem with LED on Moto G 2015
My daughters phone has this same problem, just turned on one day and has never turned off even when powered off. I would like to avoid rooting, but would if needed in order to use some of the apps available but require root. Have not factory reset yet. Maybe opening it up and disconnecting the battery. Any ideas. Thanks

Same thing happened to me about three months ago. I had the phone in my pocket while working in the yard. I guess I was sweating too much, phone was wet when I took out out. The LED was on and stayed that way for a while, although it did get dimmer over the next few weeks. Finally after about a month, the LED went out and hasn't turned back on since. Just give it time and see what happens.
Sent from my MotoG3 using Tapatalk

same thing happened to me, I was unaware of the fact that moto g3 has a led, it would be on even when the phone is switched off, but after days the led faded away on its own but not completely I until I rooted and tried different ROMs, now on stock ROM and the led is no more shining.

Z3 Death discharge problem

Welcome, i've readed alot of topics on the internet about problems similar to this, but nothing fixed my problem. I've tried connecting to wall/pc charger, power button + volume down/up combinations, really all the thing.
Couple days ago after my phone fully discharged ( I rarely had situation like this, I usually charge when my phone have 10-15%, but this day I couldn't. ) I came back home and tried to charge my phone, red light was ON but it still didn't charge after alot of hours. I then tried to fix it, turning on phone etc. but screen was always black and phone didn't want to charge. At first when I tried to boot the Z3 red light was blinking, but after some time it stopped. I ordered new battery, replaced it carefully (though it's battery problem) - then when I connected the new battery for the first time I though I have fixed the problem, battery charging icon showed up for a moment on screen, I was very happy. Then I disconnected charger so I could assemble my phone. Now when I try to charge my phone problem is this same.. like with old battery - Just red light, not turning ON, not blinking. Powering up Key combinations with volume don't fix it. My PC Companion don't see phone. I disassembled my phone again, disconnected battery and connected it - It didn't showed any battery icon again, so why it did when I connected it for the first time? and why when my phone died for the first time red light was blinking, now it doesn't? I want to add that I never dropped my phone or used it in water - never, thats why I was almost sure maybe just battery died after it discharged.
Btw. Important thing is that USB port isn't broken, red light is always ON when I plug USB charger, but when I try to use my magnetic charger, phone never respond - no light. I also tried different cables, chargers etc. Could it really be something with the mainboard?
What could've happen? Why my phone went dead after fully discharged it ? Why battery replacement doesn't fix the problem? I don't get it, is mainboard damaged or something? Can I still try something? Maybe anyone can help me.
Please :/ I cannot afford a new phone right now, really want to try fix it, maybe somehow connecting USB cable straight without usb port can fix it? I heared people do something like this.

Poco F2 Pro does not turn on when charging

Hey!
Yesterday I've stumbled upon a very serious (to me) problem, to which I cannot find any solution anywhere - I guess nobody so far reported anything like that.
My phone went out of battery (discharged to 0% and turned off, it was when I really could not plug it to charging).
When I connected it to charging, there was no reaction apart from the red light at the top of the frame, indicating that the phone is charging, but has low battery.
Apart from that, the phone looks like it is dead. It does not respond to anything - cannot be turned on nor enter the recovery/fastboot mode. The screen simply remains black, while the diode located in the pop-up camera lights red. As soon as I disconnect the phone, the red light goes off too.
I've had exactly the same problem once in the past, but then it came back to normal after 2-3 hours of charging with the red light on. Then the light became yellow, indicating the battery is "normal" and the screen regained functionality and the system booted like normal. This time however, it has been charging for over 24 hours and the phone still plays dead and the annoying red light is still there, giving me hope that the phone is not entirely dead.
How can I fix that? Sorry if I'm posting in the wrong subforum, but that's my first time. I only used your custom ROMs and kernels back in 2015-2017, but never posted anything.
Any feedback on the problem will be greatly appreciated!

I take it you tested with another cable and or another charger?
Which rom currently?

thank you for answering!
The charger and cable does not matter, the issue is still there. The phone detects that it is being charged, right now it has been charging for about 25 hours with several breaks for several minutes (I tried turning it on with the charger unplugged).
ROM is the latest official stable MIUI release. On this particular phone I haven't unlocked bootloader or messed with software in any way.

don't bother, send it back to the seller.
.

okay, thank you. I will wait and see if anyone else got any suggestion.

Put some pressure on the right hand top of the phone or try to bend it a little bit on that spot.
When it is charging then, send it back to the reseller under warranty.|
It happened with a few users and they got under warranty a new F2 Pro. (EU).

How long did you press on power on to turn it on? It take less than 5 sec to power on normally.
Once I have to press for long time to turn it on.

I got the same problem just now. Did you discover a fix?
