[Q] MZ601 Not Charging - Xoom Q&A, Help & Troubleshooting

Hi,
I disassembled and repaired a Motorola Xoom I bought off a friend for cheap as it had a cracked screen. I have repaired it, and everything was great until I noticed it wasn't charging on the charger. Now, the difference is that it's not like the other not charging issues. The charger works fine, as evidenced by the "charging" on the lock screen. Also, AC is registered as connected in an app, but the battery is registered as "not charging". Logically, it's not a battery issue, as the battery still gives power when not on charge. Nor is it a connector issue due to the AC being recognised and the charge just sitting at its level when on charger. When in RSD mode it also states that OneWire is not connected? I wasn't sure on what that was. Is it something I've stuffed when I put it together?

dead SP5m, not charging either

help people....
dropped my SP5m two weeks back and ever since it is not powering ON
ne idea what I could do to check what is wrong?
tried switching on the phone minus the battery, but it does not switch on (correct me if this normal)
I even tried get the voltage checked of the battery, but it also shows zero, maybe there is no left in it.
Checking voltage on the phone four pins in the back also shows no signs of any volatage, even when charger adaptor is connected. (I use Moto razor charger)
any help/idea is welcome....

Have you tried powering up with USB plugged to a PC? Also, try powering up in BootLoader, sort of to make sure the motherboard is responding. Can you get a loaner battery from a friend? Your battery might have just broken internally(seen that happen on other devices).
I don't think it would be a hardware failure though. Trust me, If you only saw what I did to my SDAII, literally squezzed it between the 5th door and frame of my Van. Broke screen lens and LCD, warped housing, broke D-Pad(joystick) and, i pulled out battery, placed battery back, turned on phone, and re-dialed using bluetooth and it was working fine
For one thing, don't use any other charger except the one for the SP5m!! There are several posts in this forum that refer to problems using other chargers. If the battery is more than 50% charged, then your charger might work. Otherwise there isn't enough current output in the Motorola charger to kick-start a dead battery. So test with an OEM charger!!

Really? My experience is that Motorola chargers will charge HTC devices but that HTC chargers will not charge Motorola devices so I always assumed the Motorola devices drew more power.
Motorola charger have approx. 0,5A when HTC chargers got 1A.

[Q] TF101G - Charging issues

Hi all,
Sorry in advance if I'm asking for something that has been answered before.
I have seen lots of threads that talked about the Asus Transformer tf101 and tf101G that doesn't charge correctly.
My TF101G stopped charging after it was fully drained after the kids played some games on it. When I plugged it in to charge the TF screen came on with a big battery indicator which showed a empty battery with red at the bottom. Then it just goes off. When trying to switch on again it just briefly flashes this battery and goes off again.
I left the TF to "charge" overnight and this morning after about 6 hours of charging it had +-14% battery life.
So it appears that the charger still trickle charges the TF when it completely off, but doesn't want to charge when it powered on.
Also, the TF recognizes the cable when it gets plugged in. If off and with some power in the battery the TF starts to boot up, but no charge indicator is showed when booted and battery drains as per normal.
Could it be that this is a software issue? I would guess not, but then again I ask myself if the charger or USB cable was broken then it wouldn't trickle charge. right?
Anyone came across this yet?
I know that some people suggested the freezer trick, but I don't want to do that before I checked on this with the community members here.
Many thanks in advance for your assistance and sorry again if I missed a similar thread.

It could. The charger cable got 2 red wires thats connected to the same point on the TF.
One of the wires is your normal +5v USB power, while the other is connected to a USB3 pin to tell the charger to spit out 15V instead of 5V.
If that particular cable is broken, the charger will only send 5V.
The odds that that small wire is broken though, is... well, very slim.

Why did it discharge, and why won't it charge anymore?

Two days ago, I turned my Infinity off and docked it. Both batteries were fully charged. A few hours ago I picked it up again, and the tablet wouldn't turn on.
I plugged it into the wall outlet. It started charging and I was able to turn on the device. It had 0% charge, and the batteries on the dock were also dead. What I don't understand is: how can the Infinity and the dock discharge completely in that time even though it was supposed to be off?
I left it plugged in so that I could use it while it charges. After some time, it asked me to connect the charger and then turned itself off due to almost dead batteries. Cable was still plugged in, though the charging light was off.
Tried connecting the cable to the dock, no light. Tried connecting the cable to my computer, it didn't work. So, the cable must be faulty, right? I can still turn the Infinity on, it'll boot normally and turn itself off after it's reached the lock screen. There's a red exclamation mark on the battery icon that wasn't there in the first time I turned it on, does it mean anything serious?
I had it drain to zero once overnight. Wasn't completely charged but it was strange... hasn't happened since in fact it generally has very good battery life.
I would definitely try a new cable and or charger.
Yeah, I've asked the store for a new cable. They'll have to mail it to me, so my tablet will stay dead for a few days. Now I know why propietary connectors suck.
Anyway, it seems I'm not the only one that had problems with the charger. Many people have reported overheating, but that never happened to me. The adapter that came with my Infinity seems to be a newer model; the plugs can't be folded or detached.
Charger: I had that happened several times to the SL101. Turned out I had something else plugged into the USB and the adapter was overloaded and tripped. Unplugged for a little while for it to cool down and reset itself.
What do you mean you had something else plugged into the USB?
Anyway, I've left my adapter alone for quite some time. I'll go see if it works as soon as I get home.

I was charging a small 700 mAh battery through the USB. That was enough to trip the AC adapter.

Strange charging issue

Right, going to work so I plugged my car charger into my HTC One X but it didn't work. After a bit of footering it seems that with just the charger in the cigarette it seems fine, the htc sign lights up on the charger, but when I connect the phone the htc sign goes out and it doesn't charge. Turned the phone off and on, rebooted phone but no difference.
On arriving at work I checked it in another guy's car with my phone and got the same issue but when we connected his android phone it charged no problem - so it seems the issue is with my phone.
Plugged it into a wall charger and it no charge either. Still think it is strange that with the car charger it turns the light off on the actual charger. Any ideas folks?

Might be an issue with your USB port. Try cleaning it once.
If you are still unable to charge using different chargers, USB cables etc then its time to visit service center or a local mobile repair shop.

Fast charging stopped working

My S6 is 2 weeks old today and I noticed that fast charging (using adaptive charger I got in the box) has stopped working
Yesterday at work I put my phone on charge and went back to it after 20mins and noticed it had stopped charging.
I thought maybe it the 2pin plug point so I changed plug points and it starts charging.
Come back later and it stopped charging.
Changed plug point again and the same thing happened.
Getting irritated I put it on my wireless charge mat instead.
Today I decided to test the charger and low and behold it's now working but it's charging at the normal rate.
I tested this by using my old S4 charger and I got the same time to full message.
Before when I plugged in my adaptive charger it said fast charging now it just says "Cable charging"
Do you guys think it's my phone or my adaptive charger?
I don't have another adaptive fast charger to test with
EDIT: I was running XtreStoLite ROM, I used ODin and reloaded the latest AOD8 Vodafone SA firmware but still fast charging isn't working.
I'd say it's the charger. There have been instances of them shorting. The last Note 4 I had did the same thing.
Perhaps a silly question, but am I right in thinking that the fast charging only works when the battery is below 20% or so? I tried plugging mine in yesterday when at 40% charge and it just said 'cable charging' (using the out-the-box charger and cable)

When you use the fast charger, it'll say fast charging no matter how full your battery is.

Geez boet, how much does an S6 go for in SA?
I am having the same problem with my S6.
The fast charge doesn't work afree a week.
Last night I plugged in @ midnight with the original charger and cable at 5% and all apps shut down
It said "charging" and not "fast charging".
530am....only 97%.
This is pretty frustrating. It seems to have stopped in the last couple days.
Thoughts?
If you connect the USB cable to your PC and it detects your phone, it's proof that it's the adaptive charger. It happened to me on my Note 4, and I had it replaced with the warranty. Problem solved. Try it and you won't have any more problems. Garanteed!

Thanks - have now realised that I had to push the USB cable extra hard into the charger - that switched it from showing 'charging' to 'fast charging'

Oddly...when I connect it to my computer...it charges (slowly of course).
But the computer never detects it.
Update
@Biggenz the S6 32gig is around the R9000 mark
@BoondckSaint try another Adaptive Fast Charger, apparently even the Qualcomm ones work too. If it still doesn't fast charge take it into SCC.
@alanjrobertson my problem started out like that, I'd have to unplug and re-plug the cable in then it would work. Now more often than not it just doesn't Fast Charge
So, I took my phone in to Samsung Customer Care and after trying numerous chargers my S6 would just say "Cable Charging" and never show "Fast Charger Connected" in the notification bar.
They tested my charger on another S6 and S6 Edge and they both worked fine and Fast charge was working. Had the correct "Fast Charger Connected" in the notification bar too.
I had to leave my S6 there and they will repair it. The technician said it's either the USB connector is faulty or the mainboard needs replacing.
I'm abit disappointed now as my s6 is only 2 weeks old and it's already had to be booked in for repairs.
Hopefully no such issues for me - it seemed to be very much linked to the USB plug at the charger end not being the whole way in but will be keeping a close eye on it!

I hope its just the USB plug m8. I'm suffering without my S6

Have you tried depleting battery all the way down until S6 goes off by it self? Then charge it while is off all the way to 100% or leave it all night. Then see difference. Also one hint which is not quite related to your problem,but just for people to know. Fast Charging is NOT working from 50% and up to 100%. This is normal. So Fast Charge works from 0%-50%,NOT ABOVE!

The Samsung Care Center replaced the USB port on my phone and its fast charging again perfectly. Wasn't anything to do with the battery thankfully.
Before replacing the USB port the phone always showed "Cable charging" whenever it was plugged into the fast charger.
Now it shows Fast Charging in the notification area.
I am also having the same problem with mine it can be seen in odin but no mtp no matter which computer i use ... (yes drivers were correctly installed) also not showing fast charging with stock charger and about 4 different cables that i know work with it in the past. My phones been flashed will this void my warranty for usb repair ?

I took mine in and they fixed it. This was at the Samsung centre in my city. Took them a week because they didnt have any USB ports at their branch and had to wait for it to be couriered from Johannesburg
I'm having the exact same issue with my S6. Only a couple of months old and only showing Cable charging and intermitantly stops charging. I'd say definitely charging port. I've tried the samsung fast charger, the sony z4 tablet fast charger, my aukey quick charge 2.0 car charger and my aukey portable quick charge 2.0 portable battery. Bit annoyed
Same issue here. comp does detect it then it drops over and over. same with whatever charger im using or cord. 2 months old 920W8.
i see one of these in my future.........................
