[Q] Battery completely dead - Eee Pad Transformer General

It seems my power cord is not charging the unit or there is something wrong with the battery, this happens after I upgraded to 3.1, any help would be much appreciated.

By any chance, did you use an extension USB3 cable on the charger at some point? I tried one last week, and immediately had the charger completely fail.
I finally concluded that the card may have caused one or more of the 5 pins on the charger base to deform.
I was able to restore it by carefully reforming the pins, very slightly upward, using a very sharp needle and a jewelers loupe. Knock on wood, it's been working fine since then.

No, did not use any other USB cord, the package only comes with one USB cable.
Asus support will send a RMA to me, hope BestBuy carry the transformer so that I can try their cord.

take the country adapter off the charger and reinstall it. Sometimes the small pins get bent and do not make contact.

I see more people having the same issue - the charger does not charge, I got the RMA from Asus, but really want them to send me a new charger.

How long hasn't it charged? Sometimes the charger will just stop charging out of the blue, then work a few hours later.

JasJar won't charge any more...any ideas?

I just posted on the accessories forum about my experience with the Brodit active holder that I purchased. Mounted it in my car, and plugged the brodit charger in. Fuse in car charger went bang (not literally). Now I know it's not my power adapter in the car, as I've been using another JasJar charger and GPS charger for ages, so I went to Halfords and bought some replacement fuses. Tried them in the charger. Every one died too instantly.
I assumed the charger must be faulty, and arranged to send the holder back to Clove to replace it. It wasn't until I plugged my JasJar into the normal charger last night that I discovered it was no longer charging at all. I tried unplugging and replugging. I tried using the USB cable in my pc. Nothing works. Even the other car charger won't charge it any more.
I'm guessing I now have to send my JasJar to HTC for repairs and be without it for a couple of weeks. I'm not too happy about it though, and thought I would ask here first if this has happened to anyone else and if there might be a way to get it charging again without having to send it away.
i had a similar problem, i went to france with a charger that had a changable head, with pins for the different countries on click in plates, and on the top was a usb socket.
i took a standard usb to mini usb cable with me figuring this is a usb charger like the one that came with my phone but no, i couldnt get it charging, then after 12 hrs of it refusing, it eventually kicked back in, i sussed you had to use it like plugging it into a pc, ie, it turn it off, wait, then plug it in. bingo it started charging again.
its working like activesync, right pain, shoulda just taken me charger and a mains convrter
sorry it doesent really help but its poss related

similar problem. but i change the port miniusb. 30 dolares in mexico.
no problem, is easy. and now is working ok.
Well I've sent it in for repairs now. Couldn't get the thing to charge.
this forum is amazing...if there is an information available, you can bet it you can find it here...:
thanks carnivor: I had the same problem, but just was not smart enough to get the idea to shut it off and then on...with your help i solved the problem...i still don't get it, why it did charge with the original charger or with the usb cable from the pc and not with the generic usb charger and that same cable....and actually: it depended on the ROM installed: with the qtek rom it did not matter, with the t-mobile it did..
anyway: now it works. thanks!
I notice that the power lead is thinner than a usb lead so there may be less wires inside, ie 2 + ground instead of 4 + ground, the lack of TX and RX connections may well be what causes it. Im not going to hack into the charger cable just yet to find that out.
Intresting about the rom versions changing the fact if you can have device on before sync or not. Im not going to reflash now with an update around the corner im just going to wait for that.

yes, but interestingly it also doesn't work with the same cable that syncs and charges from the pc, when this cable is connected to the lighter or the generic USB charger...so the mess starts already in the charger.
but bottomline: as long as there's a workaround...

Charger issue

I haven't seen anyone else complain about this, so it might just be a small defect or isolated incident.
I always charge my phone during the night while I sleep and just recently woke up to find the phone only at ~70%. For some reason the AC adapter seems to be malfunctioning. Since the issue has started, I managed to get it to charge to full one night, but the rest of the time it seems to stop charging. It recognizes it being plugged in initially but then it pops up with the notification saying that the charger has been unplugged. I've tried reconnecting both connectors which will sometimes get it to start charging for 15-30 seconds before it shows as disconnected again.
It works fine via USB connected to a computer so I can only assume it's an issue with the wall adapter. I'm not sure if there's much I can do if it is an issue with the adapter but wanted to see if anyone had any ideas that would be worth trying before I give up on the adapter. Also wondering if anyone else has had this happen.
I don't have that problem. Call and get it replaced. All you news is a USB AC adapter.
Have you checked the socket you are plugging the charger into? Have you tried a different wall socket or socket on the power strip?
Are you using a Motorola brand wall outlet and usb? I was using an aftermarket cable and had this issue. So I got a branded cable and now it's fine

i had same issues
my atrix would only charge also to 70% so i was about to return it. i forgot that it also came with a stand alone battery charger to charge just the battery. charged it and then put it on my atrix and said 100% again. hope this helps..
Yeah get the wall socket and make sure that's not the problem. Also I can't imagine it being the cable I use a 15 foot after market cheapo cable I got off newegg for like 3 bucks and it charges my phone all the way and I don't even use the wall adapter moto gave me I use some random one that's for one of my old phone or my nikon camera I don't remember. Also moto cable is crap it doesn't let me use adb doesn't seem to push enough power to my phone.
But thats just my 2 cents

Transformer stuck with "Connect your Charger", charging slowly

Hello.
I m having a problem with my transformer. Right now it is charging slow as if it was connected to the computer and not the wall plug. Also the message "Connect your Charger" won't go out of the screen, even if it is connected or fully charged. I flashed a custom ROM to see if it fixed something, but I had no luck. The cable works fine to connect the transformer o my PC the only thing wrong is that is is not charging properly and the message won't go off. Do you have any idea of what could be happening? My wall charger is model OB-1LF, which I believe is not the one with the known fault. Any ideas?
the adapter is surely broken.
This will sound nuts but, put your wall charger in a plastic baggie [push out all the air and then seal the bag] and put it in your freezer compartment for say 3hrs. Take it out [still in the bag] and let the charger warm up to room temp.
The charger may now work. It is worth a try. You would be trying to be sure the thermal fuse inside the charger is reset. I brought one back to life that way.

the TF uses pin 7 in the USB connector to signal the charger to use the 15v output. If the charger does not see a gnd on pin7 it will only charge at 5V as ypou are seeing. Are you using an extension usb cable? If no then check the pins on the TF and cable for bent or damaged pins. Also try the freezer as the charger may have gone into safety reset.
Thanks for the answers. I will try the bag and freezer to see if it gets fixed.
I know that this freezer trick works (also with broken hard drives too apparently), but what's the physical reasoning behind it? I swear I've seen a good explanation of it before but I can't remember..
Same problem here... Even had the charger replaced but of no use. It does charge wth a different (do it yourself) charger usig the same cable.Maybe that doesn't have the 5v/12v mode or something...
Going to order a new adapter and hope thatll fix it otherwise I'll send the entire transformer for repair i guess :/
I just got one today (got a good price on Amazon)
it just will not charge, tried all the fixes! not too happy as i went for the asus over the ipad and apparently quite a few people have charging issues with it.
charges very slowly through my laptop
From reading posts on forums is sounds like a few people are having it and Asus should of recalled the charger.
phone call to Asus tomorrow

There is overtemp protection circuit that should reset once the charger cools, but apparently it needs to cool down past room temp. The freezer is cold enough to reset it. I would not buy a new TF charger search for devcakes discussion there several aftermarket chargers that work well
Check the cable. I had the same problem. At first I thought it was because of faulty charger and had it returned and got a new one from Asus, but still had the same issue. Then I returned the cable for a new one, it worked flawlessly.
A plus: Asus gave me new cable which was much longer than the original one.
the cable is fine, used it to charge via my laptop
I had the same issue with my charger. I called up Asus and was able to send it in for repair, after a couple days they mailed me a new charger and cable.

Charging with your laptop does not involve pin 7 and supplies 5V. If pin 7 or that conductor is bad or you use an incorrect USB extension cable, the pin 7 signal will not get to the charger and will not supply the 15V charge voltage for normal charge.

Cheers will send the cable as well to be sure but am pretty confident its the power adapter.
Hopefully i will have an adapter for next week.
I had a brief play on it and i was quite impressed, the stock browser was surprinsignly good and may unistall dolphin.
I tried the freezer trick, but it didn't worked. I ordered another wall charger to see if it works. What's really weird about this is that the Connect your Charger message will not go off the screen. It doesn't matter if it has 100% charge it will still show "Connect your Charger".
In my case my Transformer didn't want to charge at all. The red light never came up while connected, the only way to fix it was to drain my Transformer all the way until shutdown and then plug it in and voila! It started charging again ever dince.
Great tips by the way!
Thanks

Just an update, after ordering a new adapter (with cable) it now works... Appearantly the cable was the problem afterall...
New cable with old charger = ok, new cable with new charger = ok, old cable with new charger = no go, old cable with old charger = no go.
And old cable with 3rd party adapter supplying 12V = ok, heh...
New cable is longer indeed, now I just need to think if I wanna go through the RMA process again for the old cable. But yeah, cable was the issue (out of nowhere btw).

The Pin 7 Connection I referenced earlier is bad. This prevents the charger from outputting 15V.

Yeah, I read your posts about that... couldn't see anything wrong with it on the outside though (with my eye) so unfortunately no clearly bent usb-pins or anything.
Any tips on things I can check? Could easily be on the inside as well of course in which case I can just forget about fixing it. At least it still works with another (non asus) adapter.
Mine was also doing a slow trickle charge. I ended up getting a new charger, but found that the problem was with the cable, not the "wall wart". I can still use my old one with the new cable and works fine as well.

Arrrgh!!! Charging Issues

Had my first issue with charging. It hasn't been on the charger for 24hrs now, finally got down to 28% and decided to charge it up while I take a nap. Went to pull it off the charger and it was down to 17%.
I tried unplugging and plugging in, tried a different wall socket, same issue. Tried my PC, it would connect so I could see the tf101 storage but would not charge, not sure if its supposed to. I tried different 5v wall chargers hoping I would see some kind of a reaction, nothing. I went back to the stock wall charger, plugged everything in and it started to work. I know people have suggested freezing the wall charger, not sure if that's the issue or not since it started to charge. It almost sounds like maybe a sync cable issue bad pin connection. Your thoughts?

the common 5v usb wall charger will not charge the asus transformer, needs 11v irc
some earlier transformers had problems with their chargers, I don't know if this still happens. I had to return my first transformer because the charger packed up, That was in August and I have had no problems since.
if it happens again you could try taking off and reseating the bit with the country specific pins, as they have been known to come lose.
two posibilities
the wallwart uses a snap in male country adapter. sometimes the connection is intermittent and it will not charge. plugging in and out moves the contacts and makes it work.
other possibility the charger senses a gnd on pin7 of the USB connector to tell it to output 15v on the positive pin. if it does not see the gnd, it delivers 5v which will charge the TF in about a day if turned off.

I'll check to see if its snapped in properly.
Mine stopped charging and seemed to trip the temp safety sensor inside the charger. I popped it into a freezer bag and stuck it in the freezer for about a half an hour. Once removed from the freezer and bag, it started working again. I haven't had issues since.

How come sometimes I am using my transformer tf101 while it's being charged, instead of charging the battery gets used up???
On the TF try blowing hard on the connection port. Dust has been known to stop charging.

What you are actually doing is using your TF while it is plugged in. It is not charging. The battery discharges because it is not charging.
Could be one of several reasons Most likely three are ( in no particular order)
1. Over temp protection in wall wart has tripped ( unplug and stick in freezer for 20 mins
2. The male country adapter ( power prongs) is not making a good connection where it connects to the charger. Wiggle or unsnap and reinstall
3. Pin 7 on USB is not seeing a GND signal from TF causing powersupply to supply %v only instead of 15V. Clean /inspect connector on TF and corresponding plug. This will also occur if you use a USB extension cable that does not have all the connections for USB 3.0

Weird charging issue...

Hand my Nexus 6P three days now. Everything has been fine until this after noon.
Came home and put it on it's stock charger took it off a few hours later and noticed it was at 78%. I put it back on the charger and say it was not taking a charge. Here is where it get strange. The phone will charge off other chargers and the Nexus Charger will charge my LG G5 but the Nexus xharger and the Nexus will not work together.
Don't know if this matters, but I have noticed that the USB-C port of the Nexus 6P is a bit tighter than that of the G5.Don't think that should effect anything, but thought I'd mention it.
As i just got it I'm considering taking it back to Best Buy, but it's the 128gb model and I'd have to wait for a replacement.
Any ideas or should I just exchange it.
OK, this is a new one...
I rebooted the device and it seem to be charging with the stock charger again.
I'll have to keep my eye on this.
In the past I've noticed charging issues (on the 6p or previous android devices) can be caused by a dirty usb port (sometimes it's even caused my phone to restart over and over). I *carefully* used a bent paperclip and a *small* piece of cotton soaked in rubbing alcohol (I used ripped the end of a toothpick) to clean out the port. I got a decent amount of gunk out of it. (Caution though, I've also broken several ports and had to send for an asurion replacements when I wasn't extremely careful while pressing down on the middle tab/contacts of the usb port.)

Hummm.... I might just use compressed air every so often to try and keep things out of the USB port. Don't wanna be sticking things in there that might break it.
But the phone is just a few days old so I don't thin that was my issue.
I have a new Nexus 6P, and mine seems very finicky when charging over USB using a Benson Leong approved Type C-to-A connector. In fact, I end up losing a charge quite rapidly sometimes, as if my Nexus is trying to charge my desktop computer (i.e. "power supply" mode), even though it's in USB charge mode. However, it will work fine on a wall charger. I try to avoid wall chargers since it's hard to beat computer power - I mean the wall charger isn't a 650W 80+ Platinum PSU with all the fancy safeties and ripple suppression. Any idea what it could be? I think it might be a software bug.

First, just use the wall charger.
"I try to avoid wall chargers since it's hard to beat computer power - I mean the wall charger isn't a 650W 80+ Platinum PSU"
you are very wrong with that statement!
Depending on the trype of USB you computer has it will only supply a fraction of the power your charger will. USB 2.0 will max out at 500mA (.5A) USB 3.0 will max out at about 900mA. Many of the ports on you PC will supply even less power, usually one one port will actually supply the the full power of the USB standard. The PSU on you computer has nothing to do with it.
It is generally recognized that that using a computer to charge you phone is very slow and only if you have no other option, and even then you have to plug it into the main port to make sure it has enough power to charge (slowly) you device. Unless you lucky enough to have a new computer with USB 3.1 type-C that can deliver up to 3A, stay away from charging from you computer.
I just tested on four on my computers USB ports on my computer and only one gave me a little over 1A and that almost 1/3 of what the Nexus wall charger can do.

My 6p did this after I used a cheap usb a-c cable off eBay to charge my device in the car, after a reboot and a replacement a-c cable (belkin this time) I've never had issues again. Like you I only had issue with the original nexus charger when I went to use it at night, other chargers were fine, and a reboot did solve the issue.

You're very wrong in your interpenetration of my statement. The low amperage is precisely what I want. If I'm in a hurry, I'll use the rapid wall charger, otherwise I charge my phone overnight; it's habbit and convieniet for me since I have a small room and sleep next to my computer. The slower charge puts less wear on battery and it doesn't trickle as long either. There is also a redundancy of protections - the surge and overvoltage protection of the motherboard, from the PSU itself (including ripple/noise suppression) and then there is the surge protector the computer itself is plugged into - there isn't any safer or cleaner power in the house for charging my phone.
