[Q] Black screen but charging led lights up

[snooze1973]

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.

 

[snooze1973]

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?

 

[snooze1973]

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

 

[snooze1973]

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]

1. Plug it into the charger
2. Hold the VOL DOWN key
3. While still holding the VOL DOWN key, press and hold the POWER key
4. 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.
5. After holding the keys down for more than two minutes, release them.
6. The Flash Boot screen will display, and the Normal Reboot option will be highlighted
7. 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 hv been facing the same problem since past 2 days, it was working gud wen suddenly it went bad. i remember using it and putting it back into my pocket & after like 10 mins wen i tried to open it, it didn't respond. i tried to hard reset it (by pressing vol down n power button) & by forced reset but it didnt work. now, i have put it on charge on a source of 5v 1A charger. i hope it works and works well. now my question is that i remember my cell was nearly 50% charged wen all of ds happened, so i wish to know that is dre some hardware problem or dead battery problem?? thnx in advance

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.

Same Problem to me not for me this problem is faced by several moto g users are facing this if they unlocked their device bootloader.

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.
