My Charger

So my charger just quits... but not before I hear a little zzzt, zzzt. After that sound coming from the charger box the Xoom no longer charges. Anyone else having the same problem? Oh, and after some time it seems to come around. Totally weird and frustrating.

Your charger is obviously faulty, you might want to return it to motorola.

im suffering charging problems too, although I havnt noticed any funny noises.... but that's not to say they are not there.
Ill plug my xoom in to charge at night, and i see the little charging indicator in the battery display. I go to sleep thinking all is well, but when I wake up it has stopped charging at some random point before being full.
Usually when I do plug it in at night, it does start charging right away, I have to switch off the charger first, then back on and it works.
Is this normal for xoom users, or is my charger also faulty? Its very frustrating

[Q] TF101 NOT charging

Is anyone else having an issue with charging? it worked fine for a week or more. now when i plug it in, to any outlet, it wont charge at all.. they are considering RMAing the entire unit, and im going to be torked off if i have to wait weeks to get another. argh.
just curious if anyone else is having charging issues.
thanks

My unit doesn't charge if the battery is above 90%. I see no problems there, what % is your battery at? That is expected behaviour to an extent to prevent overcharging of the battery.
Sent from my Transformer TF101 using XDA Premium App

Mine did that once and I just left it alone for awhile and it started to work again on its own.

i only noticed it because its asking me to connect to charger now.
so its at 11% right now.
Tech wanted me to trickle charge to see if i get anything out of it. Its not working.
Is there any lights on the adapter? i cant remember? but i think the unit may be bad.
SOOOOO pissed, now i have to wait weeks for a replacement to show up.
Has anyone else had a unit they have had to RMA??? is so, did they send a brand new one, sealed in box? if so, i have an extra here, ill just use it and sell the RMA one when it comes in.
thanks
EDIT: i had it trickle charging in the off position. just turned it back on. then plugged it in to wall. seems to be charging now.. WTH. wonder if its something with the dock?

Thanks
Hi
Nice to have found your thread on this - mine was doing the same thing after I had if docked. Connected it to my PC and synced and then put it back in the charger and everything is fine.
Weird.

Since you guys seem new to this forum, I suggest you read the stickies. The "Ultimate Transformer Information Thread" mentions some specific adapter issues you should be aware of.

TF101 not charging after run flat issue - SOLVED
Hello
I also had this problem. The tablet drained the docking station dry, and then neither device would charge from the adapter.
I solved the problem as follows:
1) Remove table from docking station.
2) Turn tablet off completely.
3) Plug tablet only into the charger, at this point the tablet turned on, and began charging.
4) Allow the tablet to charge completely!
5) Reconnect tablet to docking station, and plug docking station into charger.
Voila, all charged Hope it works for others who have this issue!

Mine also had charging problems. When I charged it, it never reached 100%. I took it to the Asus repair center, and they called me today and said they got it to reach 100%. Also, above 90% it reports the battery status as full.
I also to them about the battery drain problem, and gave them my tablet with the dual battery widget installed. Told them to charge both the tablet and keyboard to full, dock the tablet, power off, and wait until morning to see the results.
I'll find out what happens tomorrow when I go see them in the morning.

TF101 not charging today...
It happened already once some time ago, but leaving the power adapter disconnected from the wall plug for 10min solved the problem.
Now it's happening again... and previous workaround is not working.
Tablet is TF101, no docking keyboard, last version of ICS installed.
I've checked the various threads for suggestions: of course I tried the various reboot options; the only thing I'm missing is the refrigerator, but the power adapter is cold (tablet is not charging since 2d, and battery is still alive...).
I've not checked the cable, but have cleaned with air the connectors (just to avoid dust inside).
Any suggestion is welcome.
Thanks

I have had my charger stop working twice in the past 6 months. Both times I put the wall adapter in a zip-lock bag and placed in my freezer for 30 minutes. Upon removing I plugged the usb cable back into the adapter and bam, everything was working fine again. From what I remember, there is a temperature sensitive circuit breaker inside the adapter that sometimes gets stuck. Even if the charger is cold or has been left alone it takes the dramatic temperature of the freezer to unsieze it. Good Luck it worked for me, twice.

[Q] [HELP]Phone will not charge

Today my Triumph seemed to be draining the battery faster than normal, though I was also making a lot more calls than normal. I have a cable plugged into my PC at work which I plugged into my phone but the driver install window didn't pop up like it normally does and my PC's network connection got very slow. I unplugged it and my PC connection was fine again. I left my phone unplugged for the most part after that though I did plug it in once or twice. I don't think it was ever truly recognized by my PC at work today (it has worked before) though I'm not certain.
When I was about to go home I noticed my phone was off. I knew it was low on battery so I assumed that it had turned off due to low battery. It couldn't have been off any more than 30-60 minutes. I didn't think it should have turned off already for low battery yet though.
I plugged it into my car charger and my phone refused to turn on. About 20 minutes later i unplugged my phone and the red charging light was still on. I had to pull the battery. I then turned on my phone and it was working, but low on battery.
About 45 minutes later I drove home with my phone plugged in, but I didn't check to see if the charging light was on. The phone was still on. When I got home I tried plugging in the phone and I noticed that it was not charging. It still isn't. I have tried the following:
Restarting phone
Plug in while it is turned off (charge light comes on but not charging animation, must pull battery for light to go off. phone will not start while plugged in or charge light is on)
Try plugging into computer rather than wall
Try car charger
Swap battery to stock battery (I use an Anker battery rather than the stock. I haven't used my stock battery for a few weeks to a month. It should have been fully charged but only had less than 50%) and try everything again with same results
Right now I have my Anker battery in which was nearly dead (below 10%) plugged into the wall with it off hoping it will charge. My phone is mostly stock other than I rooted it using the b_randon14's method, installed b_randon14's tweak mod, and flashed in the Sprint PRL using a method from howard forums with the 60681 version. I had links but had to remove them due to not previously posting on this forum.
I noticed the usb cable is not solid in the prot on my phone, but it never was and doesn't seem any different. For example I can move the cable back and forth a little bit while plugged in. It remains plugged in when I do this and while the phone is off it knows it is plugged in obviously. Any ideas?

Ok... I left it plugged in while off for an hour then it started working... very odd. Nevermind then I guess, lol.

Saw this thread, was going to suggest that. Your issue seems to be one that happens across all sorts of devices that have rechargeable batteries, even Android phones (and especially $&!t MP3 players that you'll find at K-Mart). I once made the mistake of buying a $30 MP3 player that refused to turn on once its battery dropped to a certain level. Twice. From K-Mart, of course.
Thank goodness for returns.

I am still having issues and it is really frustrating. Sometimes it will charge when on, some times it won't. The only thing I think MIGHT be common between when it does and doesn't work is how much battery is left. I think it might work more often when the battery is closer to a full charge. What I often do is plug in the phone, shut it off, it will charge but charging animation isn't there and I cannot turn it on until the charging animation shows up. I think it only shows up when the phone is fully charge or close to it (I've only ever seen it when it is fully charged).
Unfortunately I don't have a lot of concrete information on this as i haven't had much time to troubleshoot and verify any of my suspicions. I do know that USB Debugging has nothing to do with it and clearing my battery statistics didn't have any affect either. This issue is very frustrating and I believe are all software based, not hardware.
Any ideas or pointers?

Out of curiosity, have tried a different USB cable? I know that you talked about switching chargers, and I couldn't tell if this was just the base unit and you plugged the same cable in or, if it was a completely different charger and cable.

I have a wall charger with a usb cable at my office, a wall charger with a (different) usb cable at my house, and a car charger with its own non detachable usb cable. All have the same issue.

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.

[Q] Sudden charging issues.

I just picked up a used TF300T on Craigslist yesterday. It was completely stock, running 4.2.1. When the lady handed it to me to check out, both the dock and tablet were fully charged and everything was functioning normally. It wasn't til later that I tried to charge the tablet/dock that I noticed the dock wasn't taking a charge, but the tablet was charging. Eventually, the dock battery went down to 0% and that's when things got worse. Now, neither the dock nor the tablet will charge. Even when the tablet itself has the cable plugged directly into it, it still won't charge. No matter which port I plug the cable into, my PC recognizes it and mounts internal storage; but the stupid thing won't charge.
I've since unlocked the bootloader, installed the latest TWRP, wiped data/factory reset, rooted, etc. Nothing has made any difference. The fact that everything was fully charged up seems to support the original owner's claims that she never had any issues with it. I just don't understand how it could be fine one minute and suddenly have issues once I take possession of it. I'm pretty anal about caring for my gadgets, so it didn't suffer any bumps or any kind of mishandling in the 24 hours that I've owned it. I'm at a loss. Any ideas?
The only activity I've seen from the dock's charging LED came after the dock was fully discharged. Now, if I have the tablet docked and the charger plugged into the dock, the LED blinks orange. I've never seen the LED do anything without the tablet docked. No idea if that's significant, but thought it was worth mentioning. I did some searching and found that some people had charging issues with their docks, but didn't stumble across anything that seems to match what's happening with mine.

The USB cables have been known to go bad, and regularly at that. The wall wart's quality is stable, but you can never tell. Now if you plug the cable to the dock and it blinks orange, leave it for a few hours. If on inspection, it persistently shows 0%, that means 2 things: either the charging port soldered onto the mainboard is kaputt (unlikely if the charger charges the tab through the dock); or the I/O controller chip (Nuvoton781) has gone AWOL (this is situated on the back of the dock's main board). The inner circuit that burned the charging part still allows for other functions such as USB and SD card and keyboard, and give you the false impression that ube alles, just for the fun of it. But don't be fooled. It has died.
If you plug the cable directly into the tab and the (a) the led shines solid orange, it means the charging circuit is good; or (b) blinks orange, it means it's charging but the battery voltage has gone too low for the tab to be useable. Normally such situation requires at least a few hours of charge. If it don't do nothing, again either the charging port (cable) has gone bad, or the cable and/or brick are. One time I plugged the cable in upside down, and accidentally forced it a bit, which resulted in my bending 2 pins inside. Had to replace port. So use a loupe and look inside all the connectors to make sure nothing has been twisted out of place. It might be tedious work, but since you're anal, you might enjoy it (lol).

Your tf300t will not charge from your computer. You need to get the USB adaptor to charge it. The Blinking orange light usually means you have an empty battery.

Thanks for the response. It was thinking along those lines that ended up leading to me figuring out the issue.

While not entirely true, my issues are actually along those lines. The TF300T actually will charge from a PC's USB port. It just charges painfully slowly. From what I've been reading, unless it's connected to the correct power adapter, it'll trickle charge, but the system doesn't know it's being charged and the LED won't acknowledge the trickle charging.
Well, after more panic-stricken reading, I figured out the problem, and it was comically simple. Apparently, neither of us had noticed that the lady accidentally gave me the wall wart (adapter) that came with her Samsung 7" tablet. It was when I was inspecting all the various connection points that I noticed the adapter said Samsung on it.
Apparently, it's as simple and stupid as the 5V output from the Samsung adapter being too weak to properly charge either the tablet or the dock. Oddly enough, it'll trickle-charge the tablet, but doesn't seem to do anything for the dock. Until proven otherwise, I'm gonna be optimistic and assume that, once I have possession of the proper wall wart, it'll charge normally. Can't wait to find out.
