as i tire of hunting for hours for a thread i post. here goes...
for some unknown reason my g4 8125 wont charge. it went dead on the charger and i was thinking that my wall charger had freaked out. well after about a day of sitting i hit the power button and the lights came on! well it was a built up charge so i know the phone didn't brick. i put it on the usb cable to see if the red light would come on and no such luck.
any ideas? r they known for suddenly ignoring the charger??? any help is great!
oh and i haven't modded anything but the carrier unlock.
*i found on ebay a few that were selling with the charger port "broken" ... this a common thing? it able to be fixed if so?

I had a similar issue a few months back. It happens that the wizard needs a minimum charge on the battery in order to being able to charge. It´s like the charging connection is made by internal software.
Probably you drained too much the battery to a point that it no longer can sustain the cellphone on enough time so it recognizes the charger and it starts charging.
The workaround would be to jumpstart the battery.
There´s a post on thiss matter but in order to give you a straigth answer, you will need to find a low voltage source (better of 5volts or less, DC). Many users have used the usb port on their pcs, cutting out a cable.
Then you will need to remove the battery from the phone, and find the (+) and (-) sing. Probably you will find that there are more than 2 power connections on the battery. I assumed that the + and + were the most outer ones and it worked for me.
Then you would need to "connect" the power source cables to the battery. Beware of the polarity. keep the cables there for about 5-8 minutes so the battery would have a charge on it.
I personally used as a power source, a small 4 AA NiM rechargeable battery pack that gave me 1.2 volts x 4, meaning 4.8 volts. So even when the battery is only 3.7volts, a 5 volts power supply as the USB port, would do the trick. Just be carefull not to overcharge the battery. If you feel that the battery is getting hot, then probably something went wrong and you must stop and recheck the polarity. After 5 minutes the battery shouldn´t heat up too much on a 5volts surge.
To use the USB you just need to cut out an old usb cable that you don´t use (from an old mouse, or anything similar. Find the black and the red cables (the green and white are data cables, so don´t mess with those). and use them to connect to the battery with your fingers.
Tell us how it went.
thanks as always you guys are like the boy scouts...always prepared!
at least i think that's their motto...isn't it? anyway thanks a million
Strange as idea but i try to post here hoping that someone can help me.
Basically i buyed times ago this desktop charger http://cgi.ebay.com/Battery-Desktop...ewItem&pt=PDA_Accessories&hash=item414fc27090
Unfortunatly yesterday i don't know what happen but it get burned.
Is it possible to connect somehow the usb cable directly on the 2 tooth where allocate the battery?
I tryed to open it and seems that only the part with Ac alimentation get burned, via usb is working as well the only problem is that opening it accidentally i removed als o the 2 small cables that go from the internal board to the thooths.
I wouldn't connect the usb cable directly to the terminals to charge the battery since USB is 5V and the battery is 3.7V without an overcharge protection circuit.
Doing without could result in damage to the USB on the computer or adapter which you are charging from. It will damage the battery and could cause a fire.
I use that exact same charger... can you explain the "burn" part? I am slightly concerned now as I leave this to charge over night while I am asleep.

Desktop Charger
This will give you a dock and spare battery charger. I was bored and browsing last night and saw it. I haven't used it. I may get one myself. Deal Extreme
Here is just the charger for a little less $$ Best Offer Buy
Today I obtained a XDA Mini S. I plugged it in with the charger they supplied with it and it seems dead, no charging light on the front. I'd been told it did power up.
When I checked, the charger is 5.2v but the battery is rated at 3.7v. I thought it might be down to this but I looked at my current Android phone and it is the same situation.
The charger has a standard mini-USB connector, the Mini S having a bespoke-shaped connector. I wasn't too worried about this as it was the same for my Touch Diamond when I had that a couple of years ago. The charger works, I tested it on another appliance
So what could be the problem? Dead battery? Dead phone? User error?
hi there, unfortunately I went through the same. Basically it's constantly discharging at moment. looks like theres a issue with some that don't keep charge in the lithium battery, it goes beyond a certain level and Bye bye Wizard.
I'm looking to upgrade my Wizard to latest rom and OS if I can, then I think this issue should be overcome. But for the moment, make sure you're charging with a decent ampage charger, something 1 Amp or over as the device can draw more and will eventually kill the battery.
Reg'rds.
Jon.

Hi all
Long time Android addict and just got myself a transformer at the weekend. I have been puzzling the best way to charge it in car (read the threads on the subject) when I happened to wander in to Asda and spotted a mini 75W 12-230v power inverter on sale reduced from £20 to £5!. They are exactly the same as ones that sell on Ebay for 2-4 times that price out of Hongkong e.g.
12V to Mains 75w Car Van Mini Power Inverter Adaptor | eBay
I bought one and tried it on the way home from the store with the Asus AC charger and the transformer and it worked perfectly.
As a bonus it has a usb port built in not only rated at 1000ma but wired to be recognised as an AC charger (many arn't) which means it will do full speed charging on an android phone. So it should supply enough current to charge my HTC Desire even when using it as a satnav (many don’t). The only downside is that the flange on the Asus mains charger covers the edge of the USB port on the inverter so you cannot use both the AC and the USB at the same time without trimming the flange on the Asus a little.
Anyway I thought this was too good a deal not to share it with you guys.

The ASUS AC charger is normally working very close to it's limits when running off fairly stable AC mains. Running off this modified sine wave poorly regulated device may be enough to push it past its limits. If you want a good mobile solution that you can use for the TF and other small DC devices, search for the thread by Devcake where he lists options and actual reviews.

Does your TF indicate charging, e.g. with Dual Battery Widget, using this bullet charger?
E.g. If it outputs 11V-12V it should indicate charging on the TF, but if less than 11V, say 5V-10V, it would trickle charge only (no indicator).
I got one from same guy, and it does not work. I measured 2.8V output.

Mine arrived today. I hooked it up to 12v and tested the pins, got 2.8v. Then plugged i transformer and waited about 20 seconds. The transformer said it was charging on AC. I havent checked to see how quickly it was charging, but it gave the charging indication with the screen on.
EDIT: Tried it on another vehicle and now won't charge. Weird!
Any update to this working?
$1.99
I use this one for my phone (HTC Desire HD). It should also be okay for the Transformer, right?

/edit 1A limit could lead to slower charging, worst case (?).. by the way, there also is a 2 ampere model : http://www.dealextreme.com/p/universal-2000ma-usb-car-charger-adapter-for-digital-devices-black-12-24v-72961.. at $4 something, twice as expensive

This one arrived today, there is one small issue with it, when you first plug it in the lighter the blue light gets bright and the asus orange light goes on and eventually green showing also the charging symbol, but if you unplug the cable from the charger and plug back in, it wont work, you have to unplug the charger from the lighter and plug back in. weird... But it works
This claims to be even more powerful. Just ordered but it will takes ages to get to me.

sorry, I don't think it will work.. the transformer needs 15V to charge, that one only is a 5V charger. i'd cancel my order.
OK, let's go over this again. The TF will charge with 5V at 1.5 amp but take forever to do so. The amps has nothing to do with it. It is the volts. If you feed the TF with 11V to 15V at 1.5 amp's or more it goes into the fast charge mode and charges in about 2 hrs. Anything that says 5V will charge the TF if you have several days to wait. If you have just hours you must charge using 11 to 15 volts at 1.5 amp or more to charge with. This is what the original power supply is doing. Please look at the specifications printed on the original charging brick. Note that it has dual outputs 5V and 15V if you plug your phone into the ASUS charger the charger is smart enough to know not to output 15V however when you plug in the TF the charger outputs 15V to charge the TF in the speedy mode.
Please read over "Dvecakes" thread for even more details and items you can use to charge the TF on the go and at home.
Hope this helps.

Has anyone by chance tried this car charger?
www.amazon.com/NTK-BULLET-CHARGER-T...Q4VU/ref=sr_1_1?ie=UTF8&qid=1324413368&sr=8-1
Also Does anyone have one of these replacement cables? I think I would probably order one directly from Asus though instead of trying to save a couple of bucks.

I want to put together a car charger to just leave in the car.
Hello
For the first time I let my XTZ drop below 40% battery.
I chargy only with the Sony's cradle since I don't really carry it around.
I get to putting it on charge when it reached 10% battery, but few secconds after it showed charge animation a pop up appeared that battery is low and should be charged. This kept showing every few secconds.
It looked as the charger contacts where not making good connection. So I tried moving it around, checked the contact pins and the lever if it pulls them out and springs where working. It all seamed to work ok. It was late and I had it wet 3-4 hours ago so I just left it off the dock till morning.
When I got up I tried to put it to charge again, but same buggy pop up started to appear...
Now I left to work, set sound off and left it to charge with hopes above 10% it will be ok...
Anyone else experienced this?

Well I have my problem solved lol.
As engineer I don't usually read everything about the spec...
So the charger I used was rated at 2A, industrial quality mind you, while the cradle is actually rated at 1.8A input and 1.8a output...
I tought the cradle is just two wires and some weights, but seems to be more than this.
Anyway the XTZ started to charge fine with the Sony charger at 1.5A.
The tablet also charges faster with the 2A charger, but only from the USB.

I don't think it's the rating of the charger - I had just posted this in the "battery broken?" thread in this forum :
GretaLewd said:
Charged mine for a while this morning in the Sony dock with power on, wifi on, screen off. Like others, I use an iPad charger (2.1A).
The battery went from 11% to 55% in about 2 hours, so about 22% per hour - though I think it slows down as the % gets higher.

I've been using an iPad charger for the last 6 weeks to charge my SXTZ either directly through the USB port or "indirectly" through the Sony docking cradle. I've had no problems - as you can see from the above quote.
By the way (not that it matters) I'm an engineer (electronic) too.
