New Prime won't charge via power adapter - Asus Eee Pad Transformer Prime

C series serial number prime worked for three days now won't take a charge. Device will connect to pc or mac via cable, just won't take a charge. Any ideas for me?

there have been other threads about this. usually its the charger overheating and putting it in a ziplock in the freezer, resets it.

Mine did that too, just leave the charger and everything unplugged from the wall for a day. That fixed mine.
Sent from my ADR6425LVW using XDA Premium.

The other issue I've seen is poor contact in the USB socket on the wall adapter. I had to unplug the usb cable from the wall adapter. Then, look at the usb socket on the power adapter. The gold pins are the usb contacts. Directly opposite of them, there should be two silver prongs. I had to use a small flat blade screwdriver to pry both of them out a little further to ensure they did their job of firmly pushing the usb cable against the socket's usb contacts. Once I did, my TF201 was able to get charge from it, again.
If you decide to replace the wall charger, I believe Fry's and Office Depot stock the asus charger.

Same thing for me.. PC recognizes it as a media device, but will not charge with wall charger. Wall charger works with my HTC Phone, so it works.
I don't think it has anything to do with the latest update, since the Dock wont charge either, and there's no OS in that, right?

Just experienced this today. I have had it unplugged for about 10 hours now, we'll see if it charges.

I had the same issue few days after I got my prime. I connected my sgs to the charger and it worked. Then connected the prime and voila-works.

Which C model do you have? C1,2,3? Just asking.

C1. There are some good suggestions here I need to try.

Wrap it in a towel and bang it against a table. That will fix it usually. Then get some pc heatsinks and some arctic silver adhesive and you can attach them to the charger to keep it from happening again.

The plug has two options, 5V (standard for USB?) and 15V. I used the plug on my old HTC phone (Ozone) and then plugged it back into my Prime and it worked. Thanks for the great tips guys.
Since the charger works in two modes, I wonder if some charges became confused and started dishing out 5V when they should be dishing out 15V. Thoughts?

Hi, I got the same problem. The charger indeed seems to be stuck in the 5V mode, since, when plugged in the tablet does get charged, even though it is not indicated, but very slowly. It is charging as if it is plugged in to a pc.
I tried plugging it into (old) phones, but I still can't seem to get it to switch back to the 15V mode.
The freezer didn't help either.
Any other suggestions?

I waited about 4-5 hours before plugging into my old phone. My other suggestion is to allow the phone to charge for a short bit (30 minutes) unplug and wait, then plug into your Prime.
I have a feeling that its a transistor toggle that isn't flipping at the correct voltage.

I've had the same problem yesterday. In my case the problem was with the charge socket on the keyboard itself. Some copper pins were deformed and that stopped the device charging. I took a magnifying glass(also for checking if any of the copper pins are bend) and a small tool to bend them back. After this it charged again. Hope this helps.

My charger suddenly stopped working from today. The Prime is detecting the connection as the screen turns ON but it is not charging. I charged my sensation using the same adapter and USB cable and it is working fine. Why can I not charge Prime via PC like phone? Is it possible? I am in India and not sure if the power adapter is easily available as Prime is not yet launched in India.
Kindly suggest.
Thanks in advance.

Hi,
I've started to have this problem today, plug it in and it does come up with the charge icon but it doesn't charge - or doesn't seem to.
However I left it connected last night from midnight until 8am this morning and it went from 13% to 17% so it is charging VERY VERY slowly although the unit doesn't actual seem to think it is.
I have it plugged in to my phone right now and its working perfectly, I borrowed the charger to my g/f last night to charge her iphone and i'm thinking this might have done something to flip the voltage as since then it isn't working.
Anyone have any ideas on this??

But if the charger works fine when charging a phone it cant be the connection at fault..
It does seem to me that the power it is outputting has dropped especially the I managed to gain 5% over the course of a night where WIFI was off and screen was off even though the charge icon doesn't come up.
Is there a way of forcing the charger back in to 12v mode??

damnit... I had the same problems a few days ago and I thought it was in the cable instead of the charger... not realising the charger has to put out 15v instead of 5v.
Does this mean the Transformer won't charge with for example, my HTC charger?
I totally messed up my cable, because I thought it was broken... when I opened up the USB plug, I noticed the yellow wire was not connected anymore, but this didn't solve anything. Eventually I messed up the cable that bad, that I've ordered a new one from ebay... but when I read this... I should have just banged the charger a few times... shait.

Has anyone actually ever managed to fix this problem? I've just contacted ASUS about it to see what they say - hopefully they'll ship me out a new charger plug or something, what a useless charger!!

Don't buy the cradle for the Sprint Touch Pro 2, stupid design

So, bought the following cradle from DayDeal's ebay store:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=350284094212
The product description says the following:
* Custom-fitted Docking Cradle
* USB connection/charging cable
* AC power adapter
* Stylus
Now the issue is with the second line. What is NOT explained here is that the unit when plugged IN to a wall jack AND the sync charge cable is plugged in to your computer, the sync/charge cable gets no more power from the wall jack and wants to get it from ONLY the sync/charge USB cable. All of this leads to the unit being grossly undercharged and therefore, complains that there is not enough charge coming from the power source and that you need to shut down and therefore the whole idea of a wall charger is useless after this.
WHY would a sync/charge USB cable which by the way is physically attached to the unit and cannot be removed, while the wall jack plugs into a proprietary mini-USB cable. I know it's proprietary because I tried first to use the wall charging cable that came with my TP2 from Sprint.
So, I'd recommend not buying this cradle unless you want to do what I'm doing now, have a USB sync/charge cable dangling from the unit and NOT plugged into the computer, but instead only plug in the wall charger and sync and data transfer via USB which is what I was doing before except now, I have a cradle to do it in.
Not a good trade-off to me. I bought this specifically to be able to sync/charge FROM the cradle.
One last thing, don't think about using the cradle if you have a skin or a hard case on the phone. The connector is so flush with the back of the charging stand that if you try to put anything BUT the phone into the stand it can't connect.
EDIT: December 5, 2009:
Been in touch with the vendor. They are going to swap out this unit for another one. They say that the unit doesn't do this at their site and that this one may be defective. I'll gladly swap this one out for one that works as unstated or at least expected. I'll post when I've gotten the new unit if this is actually a defective first unit or if this is the actual way these units work. And, I'll also try this on multiple machines so that I know it's not just my home desktop.
Another bad cradle from ebay DELUXE CRADLE W/2nd Battery Slot FOR HTC TOUCH PRO 2
When AC plugged in and USB to PC the PC USB sucks the power so the phone charges slow or not at all. Also doenst seem safe for the USB to send the power back out to the PC from the cheapo AC plug in this cradle. When used as a standalone charger AC only it sometimes fails to charge, about a 50-50 success rate. Stay away from it.
That's good info. It is the exact cradle I bought, but i bought it just for charging. I have not used it for connecting to the PC yet, but i needed a cradle that had a slot for a battery in it too.

I purchased this cradle and my complaint has to do with the USB cable that is attached to cradle. I need a long line to reach back of my PC. This attached one does not reach unless I want to view the phone from 5' away! Very disappointed. I've only had it a few days but didn't know this, sanjsrik:

It does seem slow to charge but I'll run a couple of tests to confirm.

AC adapter failed, Asus won't help

Today while I was plugged in I noticed my TF was not getting charged. I checked all the connections, rebootedthe device, and still no luck. I plugged it into my laptop and it was recognized as usual, and even charged up 1% over 10 minutes. I then plugged it into an old iphone charger and it charged a bit faster.
I tried the Asus AC adapter again and it didn't work. I called Asus and explained the issue. I was told I could order a new charger through estore.asus.com. Of course they don't have them in stock. I called the store and they recommended I contact customer support again. I called them back and they said my only option was to wait until the estore got them in stock. They said I couldn't RMA the Adapter at all. The rep said he couldn't confirm if the adapter was covered by the warranty!
I'm really frustrated right now, sorry for venting.

Man that sucks & what a ****. Try calling again & hope you get a better CS rep. GL to you.
Apologize for asking a trivial question; have you made sure that the wall adapter has locked into the charger correctly? There are two prongs in the adapter that need to click into the charger unit. I ask since I had a hard time figuring this one out
Does your TF battery discharge when plugged in? I have noticed others on here and some other sites talking about a charging problem. I got my TF today and plug it in right away since it talks about charging for 8 hours. It went from 35% to 100% pretty fast. After it got to 100 I put it on the dock and plugged the dock in. At some point the dock got a green light. At that point I hit the battery icon and saw it said 98%. It has stayed there for the last three hours with everything plugged in. The thinkpad I have at work has a preset threshold for when it starts charging. Supposidly this is for the battery health. I wonder if the TF wont start charging until it drops to a certain level. Even though my TF doesn't show charging at 98% if plugged in directly or through the dock if the dock is plugged in the dock shows a green light.

Yup. Devices will only start charging at 89-90% until full. If you disconnect the charger before it's full, most will not continue charging, until again depleted below that threshold.
OP, try turning the device off completely with the cable out (hold the power button for about 15 seconds). Then, when off, and the cable plugged into the charger, plug the charger in to the device. If the charger is working, it should power the device on, and hopefully, you'll see the charging icon.

Don't know where you are in the world but in the UK they _can't_ exclude an integral part like that from the warranty. If the person on the other end cant verify if it's under the warranty I suggest you tell them to get someone that can. their lack of internal communication is not your problem.
I got the same problem.
I got my Transformer last week and I encountered the same problem. When I first called the Asus support, the guy told me that my option would be to send the whole thing to them because I did not know at that time that it was the adapter. I told him that I would return the machine to the store that I bought instead. Then, I started testing by plugging it to my PC and it worked. I also plugged a USB light to the Asus adapter and it did not do anything, so I called them back the next day. I got a better support person this time and he told me to send the adapter back to them. I got the RMA number. I know that they probably don't have the replacement yet so I will have to wait and see.
In the mean time, I find out that the iPad AC adapter will charge the Transformer a bit faster than plugging into a computer. However, it is still not that fast. It takes several hours before charging from 60% to 100%, but it is not too bad. I will have to leave with it until I get a replace adapter.
I have tried completely powering the tablet off and plugging it in, it does nothing. The adapter worked fine for about a week, but now it's toast. I'm going to try and call Asus again today and see what I can do. It's sad that others have had the same issue!
I'm going to try and find an iPad charger in the meantime.
Replacement adapter?
As I said before, the iPad AC adapter will charge the transformer but it will be slow. I tried to find a replacement adapter but I could not find anything that will provide 15V and 1.2Amp. I think the iPad adapter will provide 5V and more than 1.2Amp. Does anyone know an AC adapter that will provide more voltage?
FYI I've tried emailing Asus about getting a spare power adapter. They weren't particularly helpful:
The Travel kit is currently not available for purchase. Unfortunately we can not give a time estimate when this product will be available for purchase. For availability and price please contact your local retailer.

Even if you happen to find a 15v PSU with a USB connector on it it's unlikely to work as it would nee dto put that 15v on the right pin. The USB3 socket is not supposed to have 15v anywhere so the pinout can't be anything like a standard, they just happen to be rolling in 2 uses (USB sync/+15v Power) into one port.

AC adapter won't charge the Prime

I plugged my Prime in this morning and nothing happened. I was worried it was the USB cable or the port on the Prime so I connected the USB cable to my computer and it recognized it.
So I plugged the USB cable back into the AC adapter and still nothing. I search around and found this post about the original Transformer: http://www.transformerforums.com/fo...rmer-no-longer-charges-wall-wart-adapter.html
The post suggests to put the AC adapter in the freezer to reset some overheat cut out. It also suggests to unplug the AC adapter from the outlet and let it rest for a bit.
I did both, I put the AC adapter in a ziplock bag and put it in the freezer. I didn't want to damage the AC adapter by making it too cold so I pulled it out after about 15 minutes and tried it....
It worked and my Prime is charging again. I hope this helps and let me know if anyone else has this problem.

TF201 / XDA premium
seems odd... but whatever works..
flip
I had the older transformer and the wall plug would let you plug in the usb upside down. That may be the issue.
I had the problem of the top part of the power adapter slipping out of its place... make sure that doesnt happen :\
I have yet to find anything that works
My situation:
Transformer Prime tf201 will not take a charge and they keyboard doesn't seem to be responsive to charging either. Connecting the cable will cause the device to wake/turn on, but no charge is transferred and it shuts back off immediately after telling me that the battery is empty. No LED lights light up when charger is connected.
Attempts to fix this:
- Made sure cable works (transferred data to the computer)
- Took apart the AC adapter, messed with the prongs, and put it in the freezer. It also works when charging my iPhone via the usb
- Charged the dock by itself, keyboard by itself, and both together, nothing worked
- Pushed the "reset" under the micro SD clot
- Also, it will not stay on long enough to perform a "hard reset" with the sleep/wake button and the Vol down button.
- Tried 15+ different outlets and made sure everything is plugged in correctly.
Any help? A post with this that I missed? Something I'm overlooking? I would hate to pay the shipping to RMA and then find that it was something I had just missed... Again, device is totally dead so no software fixes will work.

I have this problem also. I went to a best buy to test things out and figured out the cables are fine its the ac adapter. The reason why it can trickle charge is the usb has two functions: 4 pin 5v 2amp charge and a 5 pin 18v (i think) 1.2ish amp charger. the 5 pins in the ac adapter aren't working so it reverts to the 5v charging. Anyone know a fix? I am trying to just by a new charger for the time being but they are out of stock :/

Had the same problem found a site(can'tfind link now) that recommended taking the plug end of the charger and bending the contacts. I bent mine out and twisted the top out just a little on each. Started charging just fine.
The USB cover of mine slips off every time, I remove it from the plug outlet. It seems like they didn't put much thought into the AC adapter.

TAblet wont charge thru outlet but thru dock

Hello everyone,
I have my 32GB TF201 with docking that I purchased 3 weeks ago. After I purchased I was able to charge my table directly thru outlet twice and once thru the dock. This week the tablet ran out of battery. I plugged it to the outlet with an empty battery and yellowish light was on. In the morning (after 6 hours of charging) I checked and the light was still yellowish. I said 'what the hell' and left home for work. When I came back I checked and saw that the battery was only charged to ~9%. I re-checked the outlet and it was not charging. The battery icon appears when I plug the cable but the status is 'Not charging' and it actually is not charging. I could then charge the dock thru the same outlet and usb cable up to 100%. I also could charge the tablet thru the dock's battery. the only problem is between the charger and the tablet itself. I will still take it to the service but I can still listen to ideas to check in the weekend.
Thanks a lot.
You probably have a busted charge port on the tablet itself. Try plugging the tablet to the computer and see if it registers. If not, more than likely the charge port on the tablet is broken.

that was the one thing I did not check and I will today. but the tablet is being charged from the dock that is connected thru the same port.
I am having the same no charging issue, but I do not have a dock. The device recognizes the computer just fine when I plug into that, but into the wall, I get nothing. Even when connected to the computer, all the connection info pops up (usb debugging, asus sync, etc) but it does not charge. Problem started this morning.

Okay, I first had this issue last night. Unplugging and plugging it back in fixed it at the time. Then this morning, I couldn't get it to charge at all (replugging it in multiple times) via AC or USB (though it did recognize the other USB things like it should). I managed to find a dock in stock nearby finally and picked one up today. Plugging the tablet into the dock charges off the dock like it should, and plugging in the dock charges it like it should. Now, miraculously, when I unplug the tablet from the dock and plug it back into the wall via AC, it works again.
So, don't know what exactly the issue is, or how exactly to fix it, but at least it seems to have fixed itself for the moment. And, now I have the dock if this happens again
hey there. i took the tablet to the service but to my luck the unit is flagged as 'defective on arrival' and I had to return it. I guess it was a ahrdware issue. I could not take a new one since the reseller was out of stock of TF-201. I am waiting for it to become available.
Wow - my tablet would not charge at all last night as I ran out of battery. I tried all the outlets in my hotel room and my PC, but it just seemed like the charge port was dead. I noticed that the trim around the charge port was a bit deformed, so the plastic part that abuts the bezel was not straight.
Anyways - I get to the office this morning and plug it in and now its charging - whew! This is eventually going for RMA since the HDMI is completely dead, and now it does seem the charge port is a bit loose. I am concerned it will happen again just when I need it!
Very frustrated with the quality issues - it's just harshin' my buzz with this tablet.
I've switched through three different primes (with issues unrelated to this) but I seem to notice that all of the chargers are like this. It seems like a security feature or bug (not sure) but if you keep the charger plugged into the outlet, it auto shuts off the charging adapter after being plugged in for a prolong period of time. If you take the charger out, leave it unplugged for an hour or two, then plug it back in. It will work again. All three of the primes I got do this. So I just remember to unplug the charger and don't leave it plugged in and the issue doesn't seem to happen anymore.
btw just a heads up:
- USB won't charge on computers unless your usb port is usb 3.0. If your usb is 2.0 it will only charge on idle (which you won't be able to tell really)
- Dock won't charge the tablet unless the tablet runs around 75% battery (sometimes higher sometimes lower) its in the FAQ

So, don't know what exactly the issue is, or how exactly to fix it, but at least it seems to have fixed itself for the moment. And, now I have the dock if this happens again

This is the exact replication of what's occurring with my TF201 with the exception that it is still not charging directly plugged into the tablet after I remove from the dock.
weird trick
I think this might be due to how some devices recognize power, i have the same issue with my iPod touch. I found that if you take the charger wire with adapter attached and plug that into the tab, then plug that into the wall it should normally work. My brother was having this issue also with his dock not charging, and this method makes it work.
Well, called ASUS support and got an RMA to send it in. Apparently something's wrong.

2m USB Cable

Does anyone know if there is an official 2m USB cable available in the UK? I bought a generic one off eBay, but it charges the phone extremely slowly....
I use the 2m cable that came with my kindle 3 and it works as well as the original one

Are you charging the phone from a USB port? If so, it's the limitation of the port, not the cable. Try with a proper charger an it should charge at a more sensible pace.

Charging speed doesn't depend on the cable but on the charger it is used with.

I'm afraid it doesn't work as well for me. I got a Kindle 3 cable, and while it does charge the phone (using the charger which came with the phone), it does it very slowly. So slowly that if I try to use the phone even for basic tasks whilst charging with it the battery still keeps heading south.
If I use the stupidly short cable that came with the phone it charges nice and quick, but every other cable I have used so far either doesn't charge or does so very slowly.
Any ideas as to why this would be?
On a related note, this sounds good, but again the cable looks stupidly short:

What are you using to charge your phone? An EP-800 or something else? I have a cheap 1500ma charger that seems to take ages to charge my Xperia. The cause was that for a full speed charge, pins 2 and 3 must be bridged. I dismantled the charger and put a tiny blob of solder on the usb port pins. It now charges like a demon.
Same story with my car charger. Before the mod I could actually lose charge when using satnav and streaming music over bluetooth.
I have a battery widget that says whether I am on AC charging or USB charging. Its name eludes me.
Oh, and a safer alternative may be to sacrifice a USB cable and bridge the pins on that.
Better than all those though is the official Blackberry Playbook charger. 2A and a long cable. Charges the phone like nothing else.
Yep, am using an EP-800.
Fortunately the latest cable I ordered works a treat, so I can happily recommend this one:

Double the length, double the resistance of the wire. Assuming the have the same cross-sectional area.
