[Q] My Prime Will Not Charge - Asus Eee Pad Transformer Prime

I discovered today that, for some reason, my prime will not charge. The LED at the top isn't on either. I recall first using it this morning around 9am and it had 25% left but I needed to travel so I didn't use it. When I wanted to use it again, hours later, the meter showed that it had 36% which didn't make sense. However, I am able to connect it to my computer to transfer files.
Here's some info just in case:
-My device is unlocked
-I had the current Primalicious Rom when I discovered the problem
-I did a factory reset in hopes to solve the problem (didn't work)
-I installed a different rom (AOKP, but didn't work)
-I installed another rom (Virtuous, hasn't worked either)
-I've tried charging my phone with the Prime's power source and that works
Does anyone have any advice?
Thanks in advanced.

Either the cable or the charger is bad. You can try the various "fixes' in the forum such as bending pins, freezer, etc just in case. In my case, I could transfer data and trickle charge via USB but nothing else. Turned out to be a cable problem.

Maybe I have the same case as you but I decided to leave it on the charger to see if anything would change and I was able to go from 17% to 82 % in 5 hours but I usually takes a shorter time to fully charge. The weird thing is that I never get a notification that the battery is charging and in the battery portion of the settings it says the battery isn't charging even when I'm plugged in.

Well, I went to Best Buy today to see if their cable would charge my tablet and it did so I'm off to get a new cable. Thanks for the help!

It may not be the cable. Check the charger as well. A lot of the chargers have gone bad and caused the same problem

If you are trying to charge by usb, you have to have a usb 3, not 2 port as the Prime requires 15v to charge and the usb 2 port does not provide that.
If you search these forums, it has been discussed in several threads, so that may be your problem. You need to use the charger that was included with your prime. Even car chargers not rated properly will not work as well.

Actually, that's false. It does not need 15v....it will work with 18 watts at 12x1.5 and 15x1.2. The Prime by itself will charge on USB 2.0, but very slow. The only difference with 3.0 is higher amps (.3-.4 average higher) from usb 2.0. The voltage is the same. It has been discussed, but I don't think you read the posts. Wikipedia has an excellent article on USB you should check on. Also, the charger that came from Asus have a variable rate from 5x2 to 15x1.2 based on resistance via the wall adapter. It's the same charger used on the 101. The 201 has better power management and can even take a charge through USB 2.0 with low usage, or at least keep the battery at a stable number. OC users will not have such success under use and wifi other than a slower dissipation of the battery. Check the 101 forums regarding the use of other chargers, both car and home, that work well. I use an adaptaplug from Radioshack that is 12x1.5. Unlike some of the problems people have been having with faulty no-name 3rd parties and the high rate of OEM failures, there have been some conventional and not-so-conventional projects that have been successful and not damaging to the tablet. Note: With the dock, you will need 12 volts at least for it to register correctly and charge since the dock battery is rated (if i remember correctly) at 7.5 volts. Maybe my results may differ based on OC kernels and their voltage tables as well as rom choice as far as battery usage. Just some facts to throw out there for readers and the OP for a better idea of what will and won't work.

Its the cable. I was also able to/charge my phone. I've found that the cable is quite delicate and doesn't like to be tied up, etc.

I have just had the same problem. Stock charger worked yesterday then wouldn't work today. Just stopped. Wouldn't light up or charge did not know why. I read a few of these forms and they kept talking about pins in the usb.
I got a torch of and looked at all the connection on both sides of the cable and the wall charger. Looked fine for my untrained eye
But i thought i would play with the pins in the usb cord side anyway. Plugged everything back in and it worked fine. Job done thanks to xda forums.

Mine stopped working a few months ago, so I unplugged it from the wall for a few days and left it alone. Decided to try it a few days later and it worked no problem. No idea what the issue was lol... Everything was plugged in fully and properly, and the outlet I used was the same both times.

[Q] Not charging? :S

Hmmm, this is a weird one guys.
I can charge my X10 only if it is plugged in to the USB port via the computer. However, when it is plugged directly into the power socket, it does not charge. Now, I've tried two different chargers, and both work when charging another device (my iPod Touch).
I don't understand. The cord can't be broken, since it works when charging from my computer? Yet, the charger (the thing that plugs into the wall) can't be broken either, since another charger didn't work and also both have the ability to charge my iPod.
What's up? :S
Thanks in advance.
NOTE: Even when charging while off works on the computer, just not when it's plugged in (and I am not using a custom kernel either). I doubt the ROM matters (since it still has the above problem while charging when off), but even so, I'm using v061 of Wolfbreak's 6.1.3 ROM.
Bump bump, bump it up!
Do you use the original SE in-wall charger? If not, thats the problem, if yes I recomend to test with a different wall charger (eg. from another device)
May be the cable it faulty? Because the PC charging uses a less amount of Volts (to my knowledge) and the charging while connected to PC is very slow. Did you try with any other Official cable?
It could possibly be your cable as mine broke a few weeks back (Same Problem), I just replaced the cable now its fine
Guys :-/
Went out and bought a new cable, and still not charging from the power Only from the slower laptop USB port :'(
I think it may be the X10 itself..
I am still suffering from this problem And sometimes when it's connected to the PC and displays 'charging', it instead discharges

Rockdale? 6 weeks?! Not going that far. :-/ I can live with just charging from the PC at the moment.
Thanks though Sad news indeed
Is is still under warranty? It will eventually stop charging from the PC too. I was waiting for parts to arrive so maybe they have them in stock now. That was 6 weeks from melbourne and back.
Going through the same thing in the US. I was told repair would be 5-7 days, but I'm sure I'm looking longer. If it comes back within the time frame they gave me I will be pleasantly surprised. I hope you're still under warranty and do your self the favor and send it in or soon you will have a very expensive paper weight. Good Luck!
I went through the exaxt same thing. It stopped charging from the wall but could only charge from computer but eventually stopped charging altogether.
Did you try taking out the battery and plugging in with the original se microusb cabe to the wall. After 5 min. put the battery in. First time didnt work for me but then i took out the battery again and put it back in immediately and then it turned on.
try getting a usb-to-wall charger, and plugging your computer usb cable into wall.

Out of curiosity, how long before each of your X10's stopped charging altogether? :S
Because, for me, it's been longer than two months and throughout that time I've managed to keep charging it via the computer.
Thanks.

I've 3 usb-to- chargers here:
From a MP20 phone, generic charger that can't charge my phone and also can't charge most of other devices, output power and voltage are low.
From an old Ipaq(not ipad) it does charge my x10 for some reason takes longer than the original, it says on it 1000mA and 5V, I don't remember the real amp and voltage on it.
And the original one, always charge really fast(2 hours for a full 0 to 100% when the phone is ON)
Conclusion, buy and original charger if you not using one, which seems to be the case.
OR, update your baseband if possible, as battery issues are normally related to baseband are normally the cause of this errors.
To make sure you can always try to do a SEUS repair.

Sorry to say this, but your are wrong man.
My charger says 5.0V which is exact the same voltage as any USB ports(exception for some internal USB ports used commonly for bluetooth and other low consumption devices that use 3.0 to 3.3V).
The difference is mainly on the amount of power amp it can supply, the original usb cable + wall charger provides 700mA, while in the PC USB 2.0 ports provide 500mA, 1.0 USB provide 100mA and 1.1 I don't remember now, generic usb wall chargers say sometimes they provide 500mA but they mostly provide 30l0mA and sometimes they do not provide on 5.0V they oscillate between 4.6 to 5.2V a good usb port have to provide 4.95V to 5.1V any difference from this may even burn a phone if higher and not charge or reduce a battery life if too lower.
Everytime a battery is not charged up the end of 100% they battery life gets a bit reduce as next time even if you leave it to charge up to 100% it won't really be at 100%, this can only be seen by measuring the battery voltage after the charge, fully charge it must reach up to 4.7V
on the battery or something like this.

If the cable is too thin(like 1.0 usb cables they can't handle 500mA if connected to an already extended usb port it may not get recognized and also not even charge.
Laptops usb ports may not allow 500mA it different for every laptop, some work, some doesn't and others your have to set that on bios.

Always when connected to the PC it should say charging, if it did say discharging at some point then there was something wrong.
But charging on the pc is very slow and not good.

Fast Charge Kernel

So I am eagerly awaiting S-Off and flashing new ROMS/kernels/radios and I started to think about how slow my Rezound seems to charge. I know that the Thunderbolt had some kernels that included fast charge capability. Just think of the extra juice we can get in a short amount of time with FastCharge, UnderVolt/UnderClock, and more precise power management.
Does anyone know if this is in the works for the Rezound?
My Rezound charges up pretty fast, especially compared to my Droid Charge.

if your charging on USB it wont be giving the phone full power, to remedy this get a spare cable and disconnect the data so only the power is working
not sure if it works on the computer, but in my car it definitely worked
yeah definitely do a search for USB AC Charging. You can take those car chargers and wall chargers that don't give you the full 1A and do a quick solder job on them to make them work. I just did it with two of mine and it works great. Battery info now says Charging (AC) instead of charging (USB) and they both pull north of +700mA while charging instead of ~+300mA when on regular USB.
Yeah they called it the charge cause its always on the charger

i did that. opened one up and clipped the green & white data cables. the phone still says "charging usb" though and doesn't seem to charge much faster...
Yea, I have tried every possible method of grounding out the data pins. I currently have my phone connected to a computer power supply I converted to a desktop supply with 4 USB charging ports. It can supply up to 13A if the device needs it. The data pins are all shorted and the housings grounded. The phone still says USB Charging....It does seem to pull more current and does seem to be charging faster.
I know that there is some hardware limit on the charging current, but with an SBC kernel (please someone make one...) I think that this bug will be fixed. I am going to try the Trickle Charge technique from previous HTC phones to get a full 100% charge. I will let you all know how it goes.
Or ...
Fast charging is built in ...
... turn off your phone when charging, and use a 1A charger.
DONE.

So I tested this idea that Fast Charging is "built-in", I used a usb cable that I split connected through an Ammeter to test how much current the phone was drawing from the charger in the one and off state. From my tests I found that my phone, no matter what the state does not draw more than 400mA from the supply. My charger is capable of supplying up to 13A to the four usb ports I installed. I also tested this with the HTC stock charger rated at 1A. This had the same results. I think that there is a hardware/software limit built in.
Just to be clear and justify its place in Dev, this thread is asking if there are any developers out there who are working on an SBC (Superior Battery Charging) Kernel for the Rezound. I fully understand the workings of power supplies (I'm an Electrical Engineer) and am just trying to see if anyone is working on this.
And it still belongs in General. That doesn't justify it. If YOU developed a Kernel, or were posting it, then it could be posted here. Questions, suggestions, complaints, ideas, etc belong in General.
Not sure accurate battery monitor widgets are, but mine has shown upwards of 850mah on charging and over 700 on draw (never saw that on my thunderbolt).
It does seem to slow down as it gets close to full (over 90%), then I never get more than 200mah charge.

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:
http://www.sonymobile.com/gb/products/accessories/quick-charger-ep851/
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:

Nook Tablet will not turn on

Hello,
I have a Nook Tablet, 16GB model, that I received during the 2011 holiday. This summer, about 4 months ago, it stopped turning on.
I have flashed it with CM7 Alpha from CelticWebSolutions, but that was at least a month before it stopped working. CM7 ran fine while it was working. There is no physical damage to the device. The Tablet does not even get warm when plugged in and the screen does not turn on. Windows does make a noise when the device is plugged in but nothing is recognized.
I am not sure what other information I can give. I would have posted this immediately to the forums if I was not so preoccupied this summer. All help and advice is greatly appreciated.
Cheers,
Not to be super obvious, but have you tried holding in the power for 20 seconds? Then plugging it into the wall charger and letting it sit all night?
Sent from my Slider SL101
Thank you Solar.Plexus,
I had tried charging overnight, and holding down power for 20 seconds. However, your post had me think of trying the stock nook cable - the one with the extra pins. I charged overnight and sure enough, it worked!
Now, when I try a microusb cable to charge, it still works. Why would a microusb cable still not charge the device before, but does now? What could the extra pins have possibly done?
Anyway it is working now. I am sorry if this post has polluted the forum. Please remove if necessary.

FWIW - The B&N USB cable has the extra pins because it provides a higher charge rate (more current) that the USB "standard" allows. In theory, a standard USB connection should charge the Nook, but it will take much longer. I'm wondering if the Nook was so discharged that the charge circuit wasn't being triggered by your USB connection. Was it your PC or an external charger? It's also possible that your USB connection voltage is too low. A fairly common problem. My Droid X is really picky about charge voltage.
From feeble memory, B&N charger = 1 Amp or 1000mA. USB = 500mA max.

Thanks, wellersl. This summer I had tried charging overnight with my regular microusb cable, which I believe came off of a wall charger. Before my Nook died, I had last charged it on the road using the same USB cable, but with a car to usb adapter. You have a good theory, though. I hope if anyone runs into the same problem, they will find these posts and try out the stock cable. I never like to use it because it is incompatible with other devices while using up a USB port.
I have been using my Nook most of the day. I updated CM7 and have done a factory reset - all on battery. After roughly 6 hours on battery it says I have 81% battery left. I am hoping the battery life has not been negatively effected by a full drain and four months of neglect.
It has the extended pins because B&N wants to make money and proprietary cables enable this. It has nothing to do with the amount of current that can be pushed.
For reference, my stock galaxy nexus charger pushes 5V at 1amp.

Allow me to correct myself. The B&N charger is rated 5V @ 1900mA (Mine is, anyway.).
Anyway, I'll have to respectfully agree and disagree. Certainly B&N is in it to make a buck. But there's more to it than that. And I'll be among the first to point out the FUD that's been posted all over the web *because * of that proprietary cable.
Standards are wonderful. There are so many from which to choose.

Same here. Glad to hear it is not just me. I just got off with NA HTC Tech Support. There official stance is that they do not recommend or support using any device other than the official charging cable and plug in device. They went as far to say that they do not support charging in the car. I just about flipped my lid on the phone.
Here is the link to their site: http://www.htc.com/us/support/howto...783&p_name=droid-dna-by-htc-(verizon-wireless)
"Only the power adapter and USB cable provided in the box must be used to charge the battery"
I was told by Verizon that this was just a scare tactic, while HTC says I am not getting the right charge and they have no answer since they do not support DC charging in the car. Any info people have is appreciated. It works fine with Hard Wired DC -MicroUSB, but not with any USB Plug in.
Any apps that would help me measure the amount of charge it is getting?
Thanks in advance.
What are the specs on your car charger?

So odd that they would do that, especially with the power draw of the phone. However you can charge using the battery packs?
My car adapter is a Macally USB car adapter model carusb10 output 5v/2.1 amp x1 500mA x2.
As for my house adapters the RCA 2 port USB wall adapter. 2.1 Amp x 1 or 1000mA x 2 I believe.

Everyone with a stock DNA unplug your charger and flip it around. As in flip the prongs. It should give you this message even with the HTC supplied one. Or try this. When you use another charger and it gives you that message unplug it and flip it. It should straighten out. I dunno. Something about the way the power is drawn.

On the other hand, any direct Wall connection with USB cable attached seems to work fine.
Also, I have the Motorola p4000 battery backup and when I plug that in, it also works fine and views it as AC.
Swapping the pins didn't work for me, same issue. Its a pita for me especially charging in the car because when using phone for navigation it charges so slow that it can't actually charge my phone and my battery decreases. I've went the route in the car I use my nexus 7 charger connected to an inverter.

From my phone conversation with Seth from HTC Support, the slow charging warning is due to the update because the update incorporates the faster charging feature that qualcomm & htc have referenced too recently (can't remember what its actually called). The phone has a new type of charging setup that makes it charge faster than some other phones.
Unfortunately some chargers (wall/car) dont supply enough voltage to activate the charging feature so while the phone does charge fine (it charges at standard phone charge rate) it cannot charge at the faster rate due to the charger.
He states that this will not harm the phone and ther phone will charge fine and it a normal time. You can disregard the warning. For those that like the faster charge rate, you have to use the right charger/cable.
Before the update our phones were mostly charging at the slower rate and that's why most didn't see a warning unless the cable being used was below the standard rate of charge.
Hope this helps

Seems ever since I updated to the latest OTA update, if I plug my phone in on certain chargers I get a notification stating slow charging enabled please connect to your factory charger. Anyone else having this issue?
It seems to do it on any charger or 12volt car to USB adapter capable of outputting 2 to 2.1 amps
Stock ROM, rooted, unlocked, s-off

Why are there so many problems about this thing lately even me, I experience this most of the time
When I use the Best Buy 2.1 amp wall charger I still get the message.
I'll need to find my oem wall charger.
So far every one I have gives this message.
I haven't seen this message at all on any of my charges but I haven't charged in the car yet. My battery usually lasts for more than the while day so I just charge at night.

Well with the faster charging enabled it does charge pretty quick especially using my nexus 7 wall adapter, even with my Nokia Qi pad. But man that last percent takes a while.
As of now I'm using supercharged hatka ROM slim 3.0.3 and getting good battery life. Even in the middle of nowhere where 75% percent of the time when I'm in the plant its searching for signal. I'll leave work after 8 hours and still be at 60%
Guess you can say its the only negative I have for the phone. Trust me the battery life is much better in the plant then my old bionic. I use to have to change the standard battery after 4 or 5 hours as it was completely dead.

Last night I received my daughters replacement Rezound from the warranty company. It came with a 1 amp wall charger.
I plugged it into my DNA and did not get the notice of slower charging and it charged quicker than I've ever seen it.
Too bad my 2.1 best buy one won't.
The quick charge capable chargers must output just slightly higher voltage to trigger the rapid charge mode.
I'll experiment some day and see.
This is a known issue. It all comes down to there being no set standard for USB charging. Android, apple, tablets, they all just seem to do their own thing.
The phone is checking the pins on the charger. If the data pins are shorted, then you get fast charging. If not, then it will default to the slower USB charging.
That last update that came through added that 'Slow Charge' warning. I saw it on my gf's DNA. My DNA is rooted and ROM'd so I don't have that. You can still check for the charging speed on a device by going to the Battery page in the settings. Up on top it with either say AC (which is fast) or USB (which is slow).
The supplied HTC wall chargers have the data pins shorted within them, so any regular USB cable will allow you to charge at the AC rate. You may remember some years ago there used to be Charging Only cables and they were regular USB cables that simply had the data pins shorted.
Most car chargers do not have data pins shorted. I have used a number of different ones from monoprice and none of them will charge at the AC rate.
There are videos on youtube showing how to open them up and solder the data pins. You can look for charging cables on amazon (but that seems lame), or you can find a car charger that just actually works.
There is a cheap Motorola charger on Amazon that will give you the fast AC charge.

I kinda figured it was something with the pins if I wasn't voltage offset.
I did find that one of my car chargers from best buy runs in quick charge. The cable I fixed, rather than using a usb cable in a slot on the charger.
The best number 2.1 amp wall charger uses a data type cable.
Maybe I'll check into shorting the pins on that sucker to get quick charge mode.

The phone is doing more than checking pins now. I have a 2.1 Amp dual charger with pins shorted and get the warning. It happily charged in AC mode before the update. The charger can also charge a nexus 10 at 2 Amps. I'm guessing the kernel devs will have to locate the source of the warning. I thought the resistance between the data pins might be the trigger, but there is no difference between the HTC charger and my dual charger. It does seem my car charger is unaffected.
I have found that to trick the phone into AC mode you have to short the the actual cable. Hence strip the insulation off the wires and short the data wires together. Has worked for me on all my chargers.

This message does not have to do with the update. I have still not updated my DNA and have been struggling with this for about 6 or 8 months. I am on 2.08. The issue has continually gotten worse since the first time I saw it. At first it would just appear about 1 in 10 times I plugged it in to a car charger. It then got to the point where it would only not show the message with a certain car charger. Now it is showing it on the one car charger that works, but if I mess around with it and unplug and replug it a few times it will finally charge normally. The last few days it has started showing the message on the OEM charger. I have cleaned out the port on the phone and cables quite a few times now, but it doesn't help. I found that doing that only helps if it gets really full of lint and the cable rocks in the port causing it to loose connection if you move it, but it does not change the slow charging message at all. The phone is also definitely not charging at full speed when that message is shown. If I have it plugged in and it shows that message my battery actually drains if the screen is on. With the screen off I only gain about 10% per hour. I am not sure where the issue is, but I think it is different in different circumstances. In my case I think it is the phone itself, but from what I have read about others experiences it seems their problem might be the charger/cord. I hope this gets sorted out soon.

It could be the charging equipment your phone or it could also be the power source not providing enough power to the device for it to charge fast so it charges slow.
