Hello,
i've got a big problem...
I've bougt a used EEE Pad with Prime 1.7 and it doesn't charge.
I tried USB-PC, the original AC Adapter and one from artwizz.
The Pad has 13% power, wenn i put it off and plug it in it reboots like it's charging but it says: 13% remaining please plug in...
What should i do?
Thanks in advance!
Try leaving it charging for a while with screen off. If when you turn it on after several hours the battery has charged a little, then the charger is only delivering 5V and not the 15v needed for fast charging. The 15V is triggered by an gnd connection on pin 7 of the USB connector from the TF. Are you using any kind of USB extension? Std USB 2.0 extensions will not work. If all else fails get a Dynex DX-UA universal camera charger ( most electronics big box stores) and set output for 11-12 V.
I had the same issue couple of weeks ago (I posted here as well) and even got an RMA from Asus to send it in; but I didn't have to. In my case the battery was empty and when I plug in the adapter it would work but would not charge - the battery had an exclamation point on it and would not change to the "lightning bolt" indicating that it is charging. Since it works from adapter, that most likely means that adapter is ok. I also have a dock and when I plugged the adapter into the dock, the dock was charging so I knew that adapter is good. However, TF was not charging regardless if it was docked or not so I thought my battery died. The day before I sent it in for RMA I had it completely off and plugged in for a day or so. After that when I turned it on the battery showed full charge and it has been charging fine since then with no issues. So as Rumbleweed suggested below, as long as your adapter is good, turn your TF off completely and leave it plugged in overnight or longer. See what happens.
Good luck.
Will the Transformer show charging with 12V and 1500 Ampere?
At the moment it charges with a 5V 1 Ampere wenn its off.
The original adapter seems to be defect, but it works two days ago...
I've orderd a cheap 5V 2A to charge it over night. I found on amazon an adapter with 12V and 1,5 Ampere. Will it charge with it wenn i use it?
The original adapter costs 39€ and with a RMA i've to send the whole tab.
edit: An adapter with 12V and 1,5 Ampere should be working?
Mine has stopped charging today while the TF in on. It's only charging when the TF is off.
It will be soon three months I have it and it's the first time it does that.
When I touch the adapter, it's hot as it used to be before today.
I've tried to power it off and on many times.
hi all
i change my charger today ... same stuff, seems recurent problem.

Hi,
I bought a wall charger for my N1 today. I was searching for one with 1000 mA output so the phone would charge twice as fast, but after having it on for a long time and seeing that it was only 22% charged, I looked at the battery status and it said "USB". I unplugged it, plugged the stock adapter and it said "AC", and started to charge at the usual speed.
Is there a way to have wall chargers that are NOT the ones provided by HTC charge at a normal speed? thanks!
Interesting... it happens the same thing with an iPhone charger, which have the same output characteristics as the stock charger. I never thought looking at the battery status
FWIW, you can easily see if your phone is charging fast or slow by installing the quick system info app (AC=fast, USB=slow).
I'm using the 1000 mA charger with the USB to micro USB cable that came bundled with the phone. Might it be the cable limiting the power?
I've been trying to figure this out too...
I bought a USB car charger to charge my phone in the car whilst driving.
However even with my phone on standby it still loses power.... I don't know whether it's because I'm using the USB cable or the charger is inferior.
It is rated a 1000mA (the charger).
I bought the HTC car charger from expansys.. bit costly at around £20 for a charger but it works perfectly for me. Drove 4 hours with copilot running, and battery remained perfectly charged
As well as the stock charger, I often use a pikie USB charger with a Nokia micro USB cable... phone reports an AC charger in use.
So my 16gb Asus Transformer has a very strange problem. I have not seen it mentioned anywhere. When I plug my unit into the supplied charger there is NO indication on the device that it is charging. It takes about 10 hours to fully charge.
Here is the really strange part... When I put the device into the keyboard dock, I get a charge symbol on the battery and it says charging. To make things even more strange the cable and wall wart provided with the tablet quick charges the keyboard dock, light is red then turns green when fully charged (no longer then 2 hours so far).
How could the charger charge the dock no problem but not charge the unit itself? My thoughts were that the dock may seat farther into the tablet then the cord does so I took a small file and took off a little of the plastic on the eee pad connector side, that did not help at all. Any ideas?
I have flashed the latest software update, and I have done a "Factory Data Reset" and it will still not "quick charge" from the supplied charger, only from the dock.

I got the same problem,i don't have the dock.I see a hole next to the camera but when i charge it there is no light,WTF

I must admit that I expected to see a charging light on the pad itself, I think the hole you mention may be the light sensor.
When I use the official charger, I get a lightning bolt symbol and it charges fairly quickly. When I used my Kindle charger or an HTC one and plugged the USB into them, I had no indication it was charging and it was really REALLY slow...

The ASUS charger is rated @ 15V 1.2A. Most USB chargers are 5V. USB itself is rated @ 5V. So I donno how it can use 15V via USB. I tried several different chargers with much higher amperage but no luck at all. Quite strange I must say.
Let me clarify, The ASUS Eee Pad has no charging lite on the unit itself. The only indication is in the taskbar on Android 3.0.1. The battery will change from a green battery symbol to a green battery symbol with a lightning bolt on it when it is "Quick Charging".
There are two ways that the device charges, the first is a quick charge (with lightning bolt on batt. symbol), the second is a slower trickle charge (no indication). A quick charge should take about 2 - 3 hours to fully charge. The trickle charge will take up to 12hrs. The ONLY two ways to get a "Quick Charge" is 1. To use the provided charger (came with the unit), and 2. Is to put it in the dock. A trickle charge can be done with ANY other USB port (ie. laptop, desktop, iPod AC adapter, ect.).
My ASUS Eee Pad Transformer will ONLY "Quick Charge" with the dock. The cable provided with the unit will NOT "Quick Charge" my device.
Anyone else have this? If so do you have a fix?
ThePCTech
FIXED!
Ok, so here is the deal...
I ordered a 32gb version and I'm givving the 16 version to my wife. I tried the new plug in the old tablet and the same thing happened. So I thought it MUST be the tablet and NOT the charger as I thought it was.
Looking into the bottom of the tablet I noticed a pin that looked like it was bent. If you look into the socket with the screen facing up. The 4th or 5th pin was bent up and not sitting in the track like it should have been. I compaired this to the new 32gb version. I used a needle to gently move it into place and tried again and it charged as it should with both cables. Newegg offered to replace the unit, but everything else works great on it and, now it chages just fine. I'll just keep it.
ThePCTech
If anyone else is having a problem take a look into the socket of the tablet, it could be a quick fix.
i fixed my charging problem by doing a factory reset.........wow...
Same problem
I have the exact same problem, but mine didn't start until I applied an update from asus.
I think I may have *had* the same problem. I returned my transformer to sears after it would not charge. After my return a clearance sticker was placed on it and now after reading this thread I am considering repurchasing the transformer and getting a new adapter. But I am concerned that it may be something wrong with the tablet itself. This thread leads me to conclude it is the former. But what do you think?
I was not able to charge through the adapter - however, when connected through the USB cord my laptop did recognize it. I did not leave it connected for longer than 10minutes -I guess if i left it in for 12hrs plus I would have a conclusive answer - but to late for that now..
I got the tablet today -it had 5% battery and after trying three outlets it shutdown- it would restart and not get past the homescreen (which had the time and stated to connect the charger and the lock) it would then shutdown.
In the 20 minutes I was able to use my transformer it worked great

The "hole" next to the camera is the light sensor.

Your unit is working correctly. There is no charging indicator on the tablet only on the dock. The tablet show charge status via software in the lower right corner of the display or in setup which will show percentage.
When you connect the unit to the dock, the tablet is charged via the batteries in the dock. The goal is to ensure that tablet is as charged as possible so you can undock and go knowing the tablet is charged. The charging from the dock to the tablet will only occur if the tablet is below 97%. The indicator light on the dock only refers to the charge status of the battery on the dock, not the tablet.
Someone referenced the little light on the front next to the camera, that is not a light. It is an ambient light sensor for the tablet.
The colors for the charge light indicator on the dock are documented in the manual. As I remember it they are <10% quickly flashing orange, 10-50% slowly flashing orange, 50-95% orange, 95%+ green.
I am also having charging problems with my Transformer.
Everything seems to work fine when I used the supplied charger and the USB plug, both with dock and with just the transformer itself.
However I'm presently away and only took the USB cable with me. I've plugged the USB cable into my travel multiplug, which has a usb slot as well and I'm getting no charge at all, either on the dock or the transformer itself. Also the battery is showing that it is actually draining, even while connected to the multiplug. I've also tried connecting both the dock and the transformer to my juicepack (rated at 3.7V, 4,800mAh), but no luck with that as well.
Anyone else had these problems?

The Transformer will only charge by USB using the supplied wall adapter. Not sure why that is, but that's been my experience.
my problem too.. I got mine yesterday and updated the software straight away. it charged all night and charging worked on both the pad itself and the keyboard.
today it doeasnt..
the cable and the sockets are fine (my pc sees it and did some file transfers) so hardware seems ok. the charger gets quite hot though. does anybody experience the same? maybe its the charger? I wonder if factory reset would help...

the wall plug that came with the TF is rated for 5V-15V, 2-12A. This is a lot higher than normal USB, which is 5V,1A max. When you plug it into a normal USB jack, you are only in trickle charge mode, and i think it's only with the screen off.
I went out of town this week and made sure to grab my USB cable, but left the AC adapter at home figuring I'd just charge off my laptop via usb. Apparently not... I also tried plugging the USB cord into my iPhone AC/usb adapter with no luck. The only thing I've found is that when you turn off the Tab and connect to one of these devices, a green battery indicator will pop up showing that it is charging. Well, after about 16 hours, it made it from 15% all the way up to 48%. Does anyone know any way around turning it off to charge or why it is barely charging when it is off?

Well seeing as it has a 7000mAh battery, just about any run-of-the-mill USB charger isn't going to cut it. The amperage would have higher as well. Now i would hazard that an iPad charger (10 watts) would probably work just fine vs an iPod charger.
Your laptop's USB port isn't providing enough juice to charge fully. With the screen off it will only trickle charge and very slowly at that.
You'll need at least 5 Volt 2 Amp chargers.
You can also try this:

Or this:
http://cgi.ebay.com/190522553195?ru...ee-All-Categories&_fvi=1&_rdc=1#ht_3085wt_905
I've ordered both last week but neither have arrived yet. I'll report back.
You need a 5vdc supply that will provide 2A. 10W, not 5w as the previous post said. That adapter on ebay won't help the charge, it just disconnects the data line so it does not change its mode when connected to a computer. There are a lot of power supplies that will work and even more that won't, just made sure it supplies 2a. If you want to charge off your laptop then you will want a Y adapter similar to what is on usb powered hard drives but even then you will need to use 2 usb 2.0 or 3.0 ports and will provably only get 1a out.

So I left my tab on the multimedia charging dock overnight only to wake up this morning to the battery still at 4%! I did not turn it off though. Has this happened to anyone? The tablet is 10 days old.

The fact that it didn't completely drain to 0% makes me think that perhaps you didn't use the Samsung supplied wall plug?
The tab does not need to be powered off to charge, however you need to use a 5v 2a wall plug to charge the tablet. It sounds like your tablet was getting a small amount of juice that kept it from going to zero so perhaps the wall unit you used was 1a or .7a?
If not, I'm not sure what the problem was, but I never power my tab off and it has no problem charging with the supplied equipment.
I was using the Samsung wall adapter, but there is a USB cable extender (cable is too short) in between the adapter and the tab USB cable. I will try again later without the extender and see what happens...
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
