Dead Unit :(

Hi Guys,
I am hoping somebody can help me out here. I came home from work this evening to find that my Transformer was not powering up? At first I thought the batteries (both in the tablet, and the dock) had died, so I plugged it into the mains....nothing
Not even the little light on the side to show it is charging. I have checked different power sockets, and tried to see if my PC would recognize it...again, nothing.
I have tried charging through the dock and direct into the tab...nothing.
I was running the Prime ROM so if I sent it back to Asus I am sure they would reject any warranty claim. Can anybody think what the problem could be or give any advice?
Thanks in advance
Ben

Press power button for like 25 seconds to see if the tablet will restart.
Check if you can go on APX mod and try nvflash.
If this doesnt work i think you can easily RMA your unit without worrying about warranty.

Hi, have tried all this but nothing at all. I will try and send it back (any ideas how I go about doing that?) and hope they don't realize I had a non standard system on there.
Unless anybody else has any ideas?
Still have no idea how it happened though, both the tablet AND the keyboard? Both were working fine less that 24 hours ago!

actually sounds like you may have broken your charger (the cable) as you said BOTH devices wouldn't charge. I would look for another charger (find someone who will loan you theirs) or buy another online, just to check and see if I am right. Dunno what else to say, if it isn't the charger and your tablet won't turn on or charge, then there should be absolutly no worry about RMAing it.

I second trying a new charger. I bought one TF and the charger was DOA, after some research, apparently this is the weak point of the Asus...they make really junk chargers. You PC won't charge the TF either, at least not in the standard sense, the TF requires +12 volts to charge, if you plug into a PC over night (5volts or.whatever) you may only get a couple of percent.
If both dock and tab aren't charging, and Asus is known for crap chargers, then logic would dictate that you have a bad charger... That or you have a bad dock and tablet... A less likely scenario. Radio shack sells a 12v charger with a USB end that will charge your TF perfectly... I have one as a backup, cost 25 bucks. Good luck.

I agree with both you guys! I think its the charger also; my reasoning behind this is I left the cable plugged into my PC and every now and then it attempts to boot, it even got to the lock screen once and then turned off.
As you say USB charging does work...just very...very...slowly!
I assume it was just a bad coincidence that both dock and tablet got drained at the same time as my charger dying! I will try and get my hands on another charger to see what happens
Cheer

I got the same problem. Since I have two TFs in the house, the charger was quickly ruled out. I had Prime loaded at the time.
I tried to get the TF into APX mode to nvflash (blindly as there was no display) back to stock. I could hear the unit went to APX mode (thru the PC's speaker). Nvflash saw the unit but couldnot finish loading the bootloader.ini.
I suggest you to try the same and maybe got better luck.
Anyway, I returned (took the chance) the unit with Prime still on it. They didnot find out eventhought they didnot replace anything but putting back the stock ROM, saying NoTroubleFound (the story didnot ended here ---> another RMA).

Hi, Ok..So I left it plugged into overnight and through the day (about 18 hours) and it charged to 60%. This gave me a chance to test a couple of things; the first thing I did was to install another ROM, in this case, Revolver.
Once it had finished installing...it booted fine, and guess what...The charging worked!!! YEY for Revolver!
I can only assume by this that the Prime ROM I was using somehow managed to get corrupt and kill the battery AND not allow charging.
I am so so so glad that the Revolver ROM has sorted things. I may go back to Prime though as I have never had problems before and like the ROM.
Cheers guys for all the help that was offered!

Ok...Spoke to soon! It isnt charging from the mains, so now I do suspect the charger. However the reason I initially thought the problem was fixed is that when I plug the tablet, into the dock, the battery charging light flashes on the dock?!?!?
Almost as if the tablet is charging the dock, but I didnt think this was possible?
Oh I dont know anymore, my little brain is getting all confused!

I'm pretty sure that light flashes regardless, when the tab is mounted to the dock, but don't quote me on that. Also, try the freezer trick, seems like to me that your charger isn't quite 100% dead. put it in a zip lock bag and toss it in the freezer for half an hour and then try it again.

Oh my lord! This actually worked! lol. I have to admit to being a bit skeptical but thanks for the advice, I appreciate it loads!

No problem man, it has to do with a built in temp switch in the charger. You'll still need a replacement but at least you are operating now. Like I said previously,I recommend the radio shack 12v charger with USB end, its the enercell 12v adapter cat# 273-358.

[Q] Atrix2 battery issues , seems hardware

Searched all over but never came across a similar issue posted anywhere.
When I connect the charger while the phone is on... it "shows charging". But is does charge "real slow" .
Then when I "take off the charger" , It "still shows charging"(lightning sign).
After I "reboot" to get rid of that , it boots up with red "Low battery". But it doesn't turn off for a while ,which hints the battery itself has no issue.
Whereas when I connect in and then disconnect the USB from my "PC" , it still indicates the USB connected sign.
When charging while the phone is "off", it shows charging (with the large battery sign) but the charged level keeps @ 0%.
PS: If I keep the phone turned off while the battery is inside for 2,3 days.. the batteries drain without any clue , the phone won't turn on.
Tried all factory reset & calibrating stuff , I start to wonder if this is an issue with my USB port or the battery connectors. I might be needing experts help ..Please help
[I do not hv any warranty left for this]

Maybe you need to try a new battery.That's all.

Yeah thnx bud, I could try that If I know for certain . Else it would be a waste.
What worries me is the issue with the "USB connection to PC". Which has nothing to with the battery circuit.

Have you tried another cable?

The issue seems to be probably with either the USB cable or the port.try another cable to be sure..

Discharge while off sounds like a bad battery. Does it lose charge if you charge it and take it out of the phone?

Yeah tried another cable . Made no difference . I think I should try replacing the port . Hope that's not very expensive .

Updates for my problem, (still no clue though).
I messed up with some MOTOMIZER app and happend to change the dalvik heap size to default(don't remember the value) . Just after this the phone boots only up to "Rethink possible" screen.
It won't let me flash via fast boot , "battery low cannot program" comes up.
Then I bought an external charger and a 3rd party battery . Fully charged the battery via the ext; charger and went to fast boot. No surprises , "battery low cannot program" came up again.
It seems the phone does not recognize the full voltage of the battery , even it's fully charged.
Now If anyone with some clue, pls help me out here.

I would suggest flashing with a factory cable. With it you pull the battery and the cable powers the phone so you can flash. I have one and it's been very handy. Give me a little while and I'll post a couple of links. You can make your own or buy one from xda member sKoRpn for like $10 shipped in the U.S. if you dont want to wait on me jump over to the kindlefire general forum.

Nice..Really appreciate man. I really didn't know about these factory cables. But just now I did my research.
Then again I doubt whether my phone recognizes the voltage. Anyways , definitely worth a shot.
I found some cables for sale. There are not recommended specially for Atrix2 but for Kindle Fire , Atrix , Droid Razr etc . Will those be compatible with A2 ??

Yeah man, It works on all moto phones and the kf. Really useful when you don't have a full charge on the phone.

Sounds to me like you need to get a replacement phone via warranty. Possibly the battery too. If you are with AT&T call the warranty department. If not, then call motorola and try and use their 1 year warranty to get this fixed.

Battery simply won't charge, have a few hypotheses

So lately I've been running into a rather annoying and inconvenient problem with my beloved S3. The thing doesn't charge well, at all. Plugged into the wall, via USB, via fast charge USB...I just can't get it to charge. I went to bed last night with the phone at around 30%, plugged it into the wall, and when I woke up 7 hours later it was at 55%....not ideal. Same result when I left it plugged into my computer overnight. At first I thought it was the wall charger, but that was ruled out when I found that I couldn't charge over usb either. My current suspect is a faulty usb cable, and unfortunately I don't have another one to test. What are the odds its damaged contacts on the inside of the phone? is there a way to test/look for that? FYI I'm running beans jellybean build 2, but this problem started when I was still on ICS. Any ideas as to what could be causing it? I've noticed high android system usage (over 50%), but I doubt that accounts for the drain I'm seeing. Any help figuring this our would be appreciated.

I had this exact same issue, eventually it stopped charging at all.
Turned out to be a fault of the phone. Called Verizon, they sent me another battery to try, didn't fix anything, they then did a warranty exchange. Got a refurb phone and it works great.

Thanks for the intel. Im actually on a refurb right now due to some issues with my launch device. Was your replacement covered under warranty at no cost? Unfortunately for me I'm abroad so I can't exactly go in to a Verizon store or call them to ship a replacement.

Do wipe the battery stats and see - wouldn't probably solve the issue but worth trying !

I too have USB problems. A normal car charger will work but when I use my USB wall/laptop/car it won't charge much. When i sleep it stops charging and I wake up to 70% battery or so. I don't know if its my cable (which it probably is) or if its my phone. Where do I go about replacing my USB?

For me I think it is my AC adapter. My phone charges faster plugged into my macbook than my wall charger.

I'll try to find a new cable and see if it works. Other than that I'm at a loss. I think I've had this problem before and fixed it with a complete drain, followed by a full charge from the wall (with phone off). I can't remember if it was this exact same situation though, and also have no idea why said solution would work.

thats crazy...my device charges in 2.5hrs plugged into the wall.

Does Samsung sell the USB on their site? I don't like things that aren't exactly made for my phone.

Amazon: OEM Cable
Although I don't think you'll have any issues with any generic cables, I've used many different cables from other phones, monoprice, amazon, etc and haven't had any issues with charging any phone I have.

Alright I just had my phone plugged in for over 7 hours to get it to 100%. I'll give a progress report when I try to charge it again. Fyi it just dropped 2% in less than a minute.
UPDATE: battery still horrible. Went back to tw nandroid to rule out the possibility of a JB leak bug

Doubtful that anyone will see this, but there's a new development. My phone's LED indicator turned green to signal a full charge while the phone was still at 91%.... whatever that means

Mine was doing that same **** before it broke when it stopped suddenly just after impact with concrete.
I was about to reflash the synergy rom I was on hoping that would fix it.
Did a reinstall fix the charging issue no now you've just got a wrong indicator or is the charging issue still there.
I totally attribute this to a degrading OS... Now I'm not so sure...
Tap'd

Still persists after multiple ROM flashes. I'm gonna get a new cable and see if that works.
Update: yup it was the cable. At least it's not the phone

Well, its back at it.
At 16% earlier today the phone was plugged in, charged fine, fell on its face. Unplugged, battery pull, charging again then slows. 6 hours later it was up to 75% where its slowly been losing charge while plugged in.
Any idears?

On Amazon you can buy a battery with a standalone charger you could charge and swap batteries till you can get a new phone if it is now warranty replaced

[Q] (Help!) My Galaxy refuses to start in any manor!

So I have a Stock Non-Rooted year old Galaxy s 4g that just turned off on me one day. I have tried everything to get it turned on. It does not bring up the battery charging screen when plugged in, and it refuses to boot into download mode. I suspect a hard brick, but I don't know what would cause it. Not only did it just turn off, it was at exactly 60% battery life and it shut down when I was trying to email my friend.

Take the battery out of the phone and put it on a flat surface like a kitchen counter. See if you can rock the battery back and forth and see if there is a bulge in the center, it shouldn't rock. Mine did this to me a year after I bought it and replacing the battery solved it.

I would jump on amazon.com and buy a battery....you can find them for $5-7.00 all day long there.
You can even buy the battery for the vibrant at that price or lower and they work just fine.
I have 4 vibrant batteries i use with an external charger.

I know that the battery works, because i tried it in my friends galaxy, and his worked fine.

Tried his in yours?
How's your cable? Try a different one. I've got a handful that won't charge my phone, but, will work on my wife's Samsung (and some that will/will not charge my company phone)...

Yes, and it wont go into recovery or download mode

Man that sucks. Best advice I can give you is to call Samsung. If it's under a year they will warranty it. If it's over a year they may charge you. There a pretty good company when it comes to honoring their warranty so it's worth a shot. Sounds like critical hardware failure to me.

[Q] Red 'x' on Battery when Unplugged

I've had a look and can't find anything specifically matching my issue...
I've recently acquired a Tab 2 7.0 off eBay, and I've updated it from 4.1.1 to 4.2.2, the official upgrade. The Tab is stock and unrooted. I've been using the original travel charger to charge it (5v, 2A). There is no issue with charging, and the Tab discharges normally, it lasts about two days per charge.
My problem is that while the device is unplugged, there is a red 'x' on the battery. So the device for some reason thinks it's charging, but not getting enough power. In actual fact, because it is unplugged, it is getting NO POWER. With GSAM Battery Monitor installed, GSAM advises "Charging: Time to Full: Calculating - check back later".
There is no other issue with the Tab. Any idea what this might be, and if I can repair it myself?
Thanks for your help...

I did not have this kind of issue with my Tab since one year.
I think you should factory reset your tab which will solve your problem.

I have an original Galaxy Tab as well, so I will swap around the leads. As I say, there's no issue with charging, it's just the battery symbol when the Tab 2 is discharging. And it doesn't give me an estimate of time left before the battery drains.
I've already factory reset the Tab, but may try that again if there is no other way in a day or two...
Thanks for your suggestions.

Even stranger...
When I plug the cable into the Tab, even though it is unattached to a power source, the red x disappears.
Then when I unplug it, the x returns.
To be clear, the cable is detached from the plug and carrying no power, at this point.
I tried a factory reset, no joy. I did try wiping the cache while in recovery but got an error.

Thanks, that would be a shame. As I bought it cheaply off of eBay, it's probably not under warranty any more, so I would have to pay Samsung for the fix - which kind of negates the benefit of the cheap deal from eBay...

Ohh.
I was also suffered from display issue out of the box fault.
My tab display is blinking very fast at 50% or less britness.
I requested to replace and give new but they did not give new and replace only display even though problem was not solved.
Finally i forgot that i have that kind of problem... Haha
