ME301T 10' Won't Charge, Constant Green LED - Transformer TF300T Q&A, Help & Troubleshooting

Well one day it seems the tablet won't charge. Typically the LED by the power button will glow orange when its plugged in. It doesn't anymore and it doesn't show that its charging. The LED is also constantly green now...
I've managed to somewhat charge it (by accident) by loading it into bootloader mode (i think its charging) as the LED is orange when its plugged in.
WTF happened and how can I fix this piece of ****
Owned it for 3-4 years, never had an issue, rarely used it for prolonged hours.
Its rooted and is on beanstalk rom.

[Q] Help!! [Solved]

Hi Guys,
Does anyone have an Idea what fast blinking amber light means on DS?
My battery was low around 2% and I connected it to the stock charger and started watching a movie, after 10 mins or so my phone switched off and amber colored light started to flash, I am not able to switch it on now and after 30 mins or so even the blinking light went off.
Had Aplha CM10 ROM flashed and was working normally till now keeping my fingers crossed that it is not bricked. Please tell me it is not:crying:
EDIT:
Solved: Finally revived my phone by directly charging the battery from the USB port of my laptop. Seems the battery went too flat to charge itself in the phone.

Did it start charging when you connected the charger? when the desire S has no battery at all, and you connect the power, the light blinks, meaning that it hasn't got enough power to boot
So just make sure the charger works and leave it charging for a couple of minutes untill you get the classic charging LED on, and then try to boot again

Thanks TataoValverde, so I guess it is not bricked. I had left the phone connected to the charger overnight but still it doesn't boot so it means it is not charging. Now nothing happens not even blinking light
So is there anyway i can revive it??
Make sure the battery is making connection - use a piece of paper to hold it firmly in place if necessary.
Try a different charger - any USB one should be fine.
Or buy a new battery as its much cheaper than a new phone.
If the charging circuitry on the phone is screwed then there is nothing you can really do unless you fancy changing the main board.

[Q] anyone have their battery LED blinking after charge?

On my replacement tab running latest 3.1.1 my battery light blinks green orange after charging overnight. Once I open the smart cover, it shows charged and then the light changes green. No other problems I can tell and the battery temp seems OK in gsam. I am using an Anker charger that I used previously with the old tab. I am going to disable xposed and charge with the stock charger to see if it does the same thing.
Anyone else experience this? Thanks.
I have seen this when charging the tablet in the OFF state. It seems to blink when it's done charging. Went away when I booted it.
I also have a similar problem. The led light of my replacement tablet:
1. blinks all the time (orange green) when tablet is fully charged. This happens when the replacement tablet during charging is switched off.
2. is aproximatly 30 second green then starts blinking (orange green) and then is orange and after a while is again green then again starts blinking and this happens over and over again. This happens when the replacement tablet during chargning is powered on.
There is never solid green charging led light even if I have tried to use diferent chargers
I hope this is not a serious problem which could damage the battery of the replacement tablet. I have never seen something like that during charging of different android devices.

I had the same problem. Then it quit charging completely. I did some searching online and found a solution. Turns out the green wire from the battery had come loose. Soldered the green wire back in to place and it works. No more blinking and it's charging.
If you are going to do this, please be careful when removing the black tape strip. You may accidentally pull some of the other wires soldered to the board.
Hope this helps.

Water damage only orange led

Hey guys,
a few days ago I accidentally dropped an HTC One E8 in water and obviously it doesn't work anymore. Before buying a new one I wanted to ask, if some of our "HTC experts" may have suggestions on what else I could try before giving up.
The situation: I dropped it in water, didn't turn it off (dumb, I know) and it worked for around 10 minutes until it powered off. I left it in rice for a day and it didn't turn on or charge. At this point I nearly gave up.
I left it for in rice (about 48 hours) and - the orange led was flashing while charging. Even the screen turned on and it showed a charging symbol first and after a few seconds it showed a red circle and a white exclamation mark. After some time I could power it on and the touchscreen worked and I could use it, but it still was around 1%/0%. The screen flickered, but it was usable. I wanted to plug it in my computer then to rescue some data, but 5 seconds after I took it off power (to switch from the wall charger to my PC) it died.
Now I tried it to power it on for like 2 days, but with no charger connected nothing happens and when I connect the charger, the orange led is on constantly. I tried power/volume- and power/volume+, but nothing happens. Not even the charging indicator comes up, the screen is completely dead.
Are there any steps to try before giving up? By the way I don't want to disassemble it
Thanks in advance

Kindle keyboard - charging led goes off

Hi
I have searched for solution everywhere but didn't find any. The problem seems to be very rare since few people asked about it
I have an old keyboard kindle which i haven't used for a long time. It's Screen is completely blank.
When i plug in the charger (i've tried different ones) orange light lights up (as it should) but after 10 seconds it goes off. Kindle says nothing what this is supposed to mean.
Here's what i tried so far:
Leaving on charger for a few hours even though led light was off.
Resetting (nothing happens)
Taking off battery and testing with multimeter (it seems to hold at least some charge as it showed 4V)
Testing battery socket (it also showed 4V so no problem there i guess)
When i put battery back, green led lights up for 5 seconds but after that everything is same as it was before.
I am pretty much out of ideas at this point. You guys are my last hope
sorry for my abortion of an English

Nexus 5 won't boot, 8 blinks

I have never had any problem with my Nexus 5. It is now my standby device. Accordingly it doesn't get used much. One day I left it ON and didn't use it for 2 weeks. When I picked it up again it was OFF and didn't want to turn on. Naturally I thought the battery had drained and put it to charge.
Instead of the battery symbol on the screen (indicating it is being charged), I get a sequence of 8 red blinks on the bottom notification light (which is just above the charging port), each blink lasting 0.5 seconds, then 0.5 seconds off (so total duration of blinking sequence is 8 seconds), then 1.5 seconds off, then blinking sequence starts again.
I left it connected to the charger for 2 weeks. Nothing changed.
I then replaced the battery with a brand new OEM battery, same thing again.
I cannot get into recovery mode nor is the phone recognised when I connect it to the PC.
Any ideas? Anyone knows the meaning of this blinking sequence?

what is the current state of the phone? do you just get the blinking when charge cable connected? no boot loop ?
So currently the phone doesn't switch on and cannot be charged it would seem.
There is no bootloop.
And yes, the blinking only goes on whilst a charging lead is connected or whilst it's on a wireless charging cradle. No blinking when removed from the charger.

you said you replaced the battery , I would check that connection , try removing the battery if possible and reconnecting it. Try the old battery too if you still have .
In my experience i'v seen that blinking light in other devices when they overheat.
I only replaced the battery because of the blinking problem as I suspected a deep discharged battery. Anyway the connections are good. 100%.
I never had overheat issues on my N5 as it was just used for basic functions, no gaming etc. I wouldn't imagine the device had overheated while it was left unattended on my desk, and there definitely is no overheating happening now as it doesn't even switch on...

sounds like your hammerhead finally checked out ... the old saying goes " if you don't use it, you lose it " .... try all combinations like hold power and volume down at the same time for 10 seconds , power and volume up ..etc
other than that i'd take a multi meter and make absolute sure you have power to the motherboard , then if you still do, it could be a short ..
if you want to go even further, a complete tear down of the phone, check for corrosion ( whitish residue on terminals and motherboard ) clean off with toothbrush only ( no water or liquid of any kind ) be careful removing ribbon cables and re-inserting them ... you can find lots of stuff on youtube for that.
good luck
