I have a B50 keyboard dock that was older so didn't support the new battery saving mode in newer firmwares. I sent it in to Asus for upgrade and just got it back today.
Upon putting my Transformer on it, it asked to update the firmware, I did it.
The battery saving mode works now, but my keyboard dock won't charge!
I plug it in and the light turns on like it's charging, I use a couple battery widgets and it would say it's charging and 2 seconds later it stops.
I unplug the cable and the keyboard dock light blinks like it would if it's out of juice/very low.
My keyboard dock is stuck at 35%. I took the Transformer off and kept the keyboard dock plugged in for about 2-3 hours, put the Transformer back on it and it still says 35%!
So, is it broken? Do I need to call Asus again? sigh.
Have you tried blowing very hard at the connection port on the Dock?
The slightest bit of dust can effect the current required for a charge.
Hahahahahaha.
I've been tearing down the hell out of my TF and dock. I know the hardware inside out.
There is a small switch in the dock that controls the charging ability of the dock battery. It sits right on the side of where the chip that they replaced is at. It is very easy for them to accidently flip the switch, turning off the ability to charge the dock battery.
You can either RMA it or you can just open it up and flip the switch. Your choice.
Personally, I have no idea why the switch exists at all.

Hmm Ok, I'm pretty good at taking things apart, know of a guide to take this apart? I'll try and do it myself. Thanks!
First and foremost, doing this and telling asus about it will void your warranty.
Warning: Failure to follow my instructions right down to the letter will result in your in-laws camping out at your place for a month.
(1) Take out anything that's in your full size sdcard slot. Flip your keyboard upside down so that the keys are facing down.
(2) Gently but surely remove the 2 rubber pads that are the closest to the connection between your TF and the dock.
(3) Under there, you will find 2 small screws. Unscrew them. Please don't lose the screws.
(4) Flip the dock over so that the keys face up towards the sky.
(5) Write me a check for $3000 USD.
(6) Use your right hand and hold down the part where the TF makes the connection. Curl your left fingers into a hook, put it under the dock, and pull up. After the left side of the dock is severed, reverse and do the right side.
(7) Now that both left and right sides are off, continue to lift up the top of the dock until the side towards you loses the connection as well. Be careful not to remove too fast. There are wires connected between the 2 parts.
(8) With the connection point between the TF and dock facing away from you, the switch is a tiny black thing on the side of the left board. Look at the following picture.
(9) Flipping it away from you = on. Flipping it towards you = off.
(10) Write me another check for $5000 USD.
(11) Before you close up completely, plug in to make sure it now charges.
(12) Close up and screw in.
Here is a picture of where the switch is.
Thank You! It works!
And yeah, agreed, what a stupid function that switch is for!
You checks' in the mail!
That was fast.
Added by edit.
People, please spread the word if other people have this problem and I'm not here. This isn't the first time I've seen people complain about this.
In order to replace the chipset to allow powersaving mode, they have to work around the area of that switch. I did similar work around that area, too, and found myself keep flipping it back and forth by accident.
I had a similar experience... I just got my dock back from RMA which fixed the battery drain.
However the dock was returned, completely drained and won't charge (the light indicator on dock blinks orange) but my tablet charges fine.
I was just wondering if this is due to the switch preventing the dock charging?
I've heard that once the dock hits below 3%, it won't charge and I'll have to RMA once again...
I've also checked with dual battery widget and it shows (when my charger is plugged in) the tablet at 100% and dock being N/A (even though it also says its still charging as well)
So yeah was wondering if it was due to the switch?

It probably is the switch.
Goes to show us asus is hiring some really cheap technicians to do the job. I'm ot even an electronic technician. What I do has nothing to do with electronics at all. And by now I know the dock inside and outside intimately.
The least they could do is spend an etra micro second to check the switch before they close it up and send it back to you.
One question. How hard is it to remove the top cover of the dock... I'm trying to but it doesnt seem to budge

Yeah, that part is kind of confusing, do i dig my fingers between the gap? Because pulling it up from "under" the dock doesn't make too much sense

yeah put it just underneath the metal side lip/gap and just pull hard.
I RMA'd it second time... when I got it back, the dock was fully charged, plugged the dock into the Transformer and it showed the correct percentages, however as soon as I plugged the charger in, I suddenly get the N/A dock on my dual battery widget and the LED notification light on my dock is solid orange... guess I'll have to try open up the dock myself and see what is wrong with it...
Here is a video I made showing you how to open up the dock.
thank you so much!
This didn't work for me. My battery is stuck at 89% and will not charge or discharge for that matter.
works like a charm!
My dock was recently RMA-ed (battery was completely dead) and upon return it shows 19% charge but will not be charged. flipping the black switch completely solved it!
Cheques are in the mail.
hey guys just wanted to let you know my dock batery sussenly stopped working this morning and flipping this switch off and on again solved my problem so thanks guys
On my Nexus 5 the wireless charging and NFC suddenly stopped working..
Everthing worked properly until yesterday but suddenly my NFC tags have not been recognized and i just tried my wireless charging pad and it is also not working..
I expect a hardware problem because all the nfc-based apps are working if nfc is turned on and aren't working if nfc is turned off.. Is it a problem with the NFC/wireless charging pad or with the pcb? I guess i have to replace one of the parts but which - is there any way to find out which one? When i lay it onto the wireless charger the indication led of the charger doesn't change the color and also doesn't seem to recognize the phone, so i guess it's the charging pad which is located in the backcover?
Everything else is working properly..
Is there anything i can do about it or do i have to change any component?
Back cover, I'm pointing at you ...

My Nexus 5 has developed the same issue with both wireless charging and NFC. Previously I've had no issue with Qi chargers or NFC, now both have stopped working.
If I gently press the back cover of the phone, in the centre just under the camera it will often work again, sometimes only for a short time before failing again.
Have a look at the iFixit teardown, you can see how the back cover housing the antenna interfaces to the logic boards via a number of contacts. I believe that there is a slight flex in the back cover that causes this contact to become poor, causing NFC and wireless charging to fail.
I have the white version of the phone, wondering it the different types of plastic used on the different color version of the Nexus 5 plays a role in the rigidity of the rear cover.
Curious if anyone else experiences the "fix" of pressing the rear cover and which color N5 you have.
I had the same problem, which lead me to this thread. Based on SunburntChicken's post, I started pressing the back of the phone around the camera. Right in the middle of the phone at about the camera level, there is some give. When I pressed a bit harder, it clicked and now NFC and wireless charging is working again on my N5.

This. If you remove the back plate you may need to do this to regain NFC and Qi charging.

I'm having a similar problem with my Nexus5.
Up until yesterday both Qi charging and NFC was working, but yesterday the Qi charging became sporadic (switching off after 10 minutes, then 30 seconds, and finally not recognising the charger at all). I tried three different chargers with the same results.
NFC is almost broken. I can't beam to a friends Nexus5, but I can read some NFC tags, if I hold it very steady and in the top left corner of the phone (near the camera).
I've pushed as hard as I dare on the cover, but not heard (nor felt) any clicks. Suddenly, however, Qi charging works again. NFC is still equally patchy...
It's tempting to open it up and clean out the connectors properly, but I'm worried that I might break more than I fix...
I'm also having trouble with NFC (haven't tried wireless charging yet) - as mentioned, putting pressure on the back will make it work, but only as long as I keep the pressure on. Can you fix it with card stock, like the GPS contacts? I tried pressing hard on the back cover, but there was no click, and as far as I know my back cover has never been opened.
Thanks for the info - the charging on mine has started failing recently (very annoying to put a low battery phone on the charger at night, see the light come on and it start charging, but then it quit sometime during the night so you wake up to a completely dead phone!)
I squeezed on mine, but no clicks. Also didn't start charging. Guess I'll have to pop the back off and check the contacts. I don't have any NFC tags here to work to test with and see if both are out, but I can check when I get home.
When I got home I pried off my back cover. Looking at the contacts for the QI, they're VERY worn and basically the contact point is worn through to the plastic below:
IMG_8266.jpg by mostlytechnic, on Flickr
I bent the spring contacts on the phone side a little so they made fresh contact and now it's working great again. If it starts failing again, I'll probably just replace the back cover.

Thanks a lot, it work, I change my backplate to a white one and all of the sudden NFC didn't work, been changing ROMS several times. And then this thread came along.
Thanks a lot.:good:
After my fix, it worked for a few days but then started failing again. I assume the springs just bent back to their normal position. But I called the google and since it's less than a year old (and bought from the play store) they're replacing the phone.

Can confirm, it worked for me as well!
Thanks. Bought a replacement cover from eBay. Was about to return it as faulty as NFC and QI charging wasn't working. Clicked the back cover in as described, and it it all works again.
Many thanks to the OP for this.
Same Here
My N5 has never been opened or dropped but started not charging via Qi as well. Pressing on the back just below and to the right of the "s" has got it working again for me. There was no click though so I don't think the snap lock has come away. Just too much flex in the back cover.
Is anyone having issues with wireless charging only when the phone is on? My phone charges fine on my nokia charger only if the phone is off. While booting it also sees the charger but as soon as it says "Android" it decides it doesn't want to charge wireless anymore.
just had the same problem
without seeing this thread, i figured out the fix was pressing the back until i heard the click.
I posted the fix (with a photo) on my blog but it seems that the info was already here
Here is a link if anyone is still interested (it will show the area you need to press for the click):
http://me-ol-blog.blogspot.com/2015/08/faulty-wireless-charging-on-nexus-5.html
Google replaced my phone just under a year ago for this problem. Now the replacement has just started doing the same thing. Qi is barely working. My current plan is to buy a new back cover to fix it and then sell the phone when the new Nexus phones come out soon... was probably going to do that part anyway
I guess I just need your help... I have tried everything: pressing on that spot, replacing the back cover, cleaning the qi and NFC contacts... It all just helps for a few days, and then my N5 refuses to be charged by qi again.
Is there anything else I could try? Could it be a software issue (I'm using Terminus ROM)?
My M8 for the past week has been entering car mode for no apparent reason. Could it be there is something wrong with the USB port on the phone or something else?
It's the charger/cable you're using. My M8 does it as well with a cable (that's a power-only cable, no data pins) I use to charge my phone from my PC with. I've had 4 replacement M8s (all for separate hardware issues) and they all did the same thing on the same cable. It hasn't done it with any of the other several chargers I use at home. But when it does to it on that one cable, it only seems to do it when I try to use any demanding apps/games while plugged in. It won't do it if I'm just poking around the launcher or browser.
Mine is happening when not plugged in also.

Ahh, well then yeah, I would have to say there's definitely some hardware issue with your USB port then.
Yup, my phone is screwed its stuck in car mode, tried everything. Is there a way to edit a system file to completely disable it? Replacing phone is not an option for me.

I've tried disabling/freezing anything with the word "car" in it in Titanium Backup to no avail on my M8, it still does it with that same cable. When it does it and the "Car Mode Enabled" notification shows up in the notification shade, I can long-press it and go to app info, where it takes me to "Android System", so it appears to have hooks deep into the Android OS and something you can't really disable. This Xposed module may have some options to disable it or at least keep it from being so invasive if you're rooted.
But I guarantee you that you can get the phone replaced under warranty, even if you have it S-Off'd/unlocked, because I have done it. Unless your phone is physically damaged..? But even then, they may not charge to repair the USB port or motherboard if that's the only issue. Can't hurt to ask HTC.
I seem to have "fixed" it by plugging it in about 20-30 times and violently yanking out the cable... Not sure how long this fix will last since looking into the port I seen nothing wrong with any of the pins or any contaminants in there, also high pressure air didn't work.

I had exact same issue. It is debris stuck in the port. Get some computer duster or air compressor and it will clear it up
Nice
Hey you guys need to go to app manager then swipe to (all) under that you should disable dock mode and car mode then reboot. Should fix problem for live. Some magnets and other objects will toy with the sensors in your phone expecially the ones by the USB connector
I've been having this problem too. The Car app and Daydream would randomly open and close. I've just performed a hard reset and it appears to have fixed the problem.
----------UPDATE 3 DAYS LATER.....
So a hard reset has not fixed this. The car app did not open for a couple of days but I have had the loud speaker turning on every time I answer a call. I've just used my earphones with the phone for the first time since I performed the hard reset and now the car app is opening again. I've tried to clean out the 3.5mm socket but its not making a difference. It seems strange that the hard reset did kind of fix it until the earphone socket was used. Now I really don't know if it's a hardware or software issue!
I had the same issue with my M8 unlocked version. Also had the problem where the speakerphone would go on and off during calls and some other issues but now since updating to the newest HTC build with Android 5.0 I haven't noticed anything.
Could it be that HTC were aware of these issues and have now fixed them?
Have any of you had progress with the new update or are the issues still apparent?
Will update later when I have had more time to test the new software out but as of now it looks like its fixed.
Mine just started doing this tonight too.. no matter what kind of cable gets plugged in to it, it goes into car/ docked mode and turns my wifi on, and rotates all around when I don't want it to. It's VERY annoying. I tried doing a factory reset on it and it's still doing it when I plug a charger in. It also is doing it just randomly when no cable is plugged in.
I'm wondering if a lot of people are having this issue recently, if it was something in one of the recent updates to the HTC service pack sent out by HTC via the Play Store. Anyone know???
Well, so much for that update...
After almost exactly a week without any problems it started acting up again this morning. In and out of carnode. Guess I'll just make use of my warranty and send it in for service.
yep.. me too. Did a reset and was working fine for about a week and just started doing it again today. WTF.
This was happening to me back in the fall. IIRC, my fix was to clean out the charging port. Look for how-to on web. I think the problem is some crossed pins with dirt making the phone think it's plugged in to dock.

I had my phone sent in for service and it turned out to be a faulty speaker. They swapped it and I haven't encountered any of the problems I had prior to sending it in.
How the speaker was interfering with the operating system I have no idea, my best guess it was shorting out something but it's just a theory.
phone keeps entering car mode
I have had this issue and completely fixed it, on your phone find car mode, scroll down to a hidden settings menu, in settings disable auto dock mode, auto connect, in fact disable everything, then exit car mode using the exit button. Restart your phone and hopefully it never enters car mode again and charges normally.
I had this issue for months and bought a new phone that I didn't like so came back to the HTC and eventually fixed it.
This is the flex USB cable. They go bad and cause car mode / dock mode like this. The cable itself is $14 and you likely will be replacing the sticker speaker grills which are $11. I have personally repaired this and it is the only permanent fix. Not disabling an app. Not removing an app. This failure is due to hardware and hardware only.
BTW.... way to dig up an old thread lol.

I have this issue since three days and it's driving me mad.
Tried all the suggested solutions and nothing worked so far.
I've ordered a new USB flex cable with charge dock pcb. I'll be sure to post my experiences with that, hope it fixes this annoying issue as Dottar suggested
I'm about to go insane over this issue.
FYI im running DH's GPE 8-3-15
Something seems to be wrong with either my software or the charge port hardware. The phone gets put into "car mode" randomly, sometimes unplugged but more often plugged in. Some charge cords seem to do it more than others but sometimes and on some cords i can't reproduce the problem no matter how hard i try and no matter how much i move the connector around, then sporadically sitting on the desk it goes into car mode!
I've tried cleaning the port with a dental pick and canned air with what i thought was success for about a day but then back to car more it goes. I've tried removing or disabling anything related to car mode or sense. When going into car mode it will sometimes display the car mode notification icon and it will usually turn on an ambient display/clock.
Does anyone know how to kill car mode in regard to how android is getting a signal from the charge port to go into care mode?
does anyone know how the charge port does this electrically? i read some place that the charge port might have some sort of magnetic sensor that car docks use.
I'm very familiar with troubleshooting technical issues and not being able to reliably reproduce the issue but then having it be so bad that i can barely use the phone make me go insane!
Edit: just found a very interesting post on cyanogen forum from 2011: http://forum.cyanogenmod.org/topic/26505-disable-dock-modes-entirely/
it sounds like it can be disabled in the kernel and that the kernel module from that app might be able to be loaded without the app, i tried the app demo just for the hell of it but no dice with my Elite GPE kernel

Yeah man. Had this with one of my m8. In end it was fixed with $14 part and $11 in new speaker grill stickers. The problem is that the usb flex cables go bad.

O happy day- got a keyboard dock. Happiness was short lived; after allowing the dock to charge overnight, I was unable to get either of my tf300's to work with it. The tablets will recognize it as a charging device (you can see the 2 battery icons on the status bar) but that's it- no track pad or keyboard functions. I haven't tried to see if usb is active, though. I've attempted the troubleshooting steps I've seen online, like cold booting a tablet while connected to the dock, all to no avail...
Anyhow, obviously there's no warranty in play here, so I was curious if anyone had any know-how on servicing the dock? I read on Tom's Hardware that the dock needs to be glued somehow after disassembly, so i'd like to consider that "last resort", but if that is what it's going to take, that's okay. Anybody have any suggestions?

Well, here's a status update... I've gone ahead and opened the dock, and nothing really looked out of place, so I went ahead and reattached the various cables and screwed the sucker back together. I now have the keyboard working. The trackpad, however, still is not working. I took it apart a second time and verified that the cables for the trackpad were plugged all the way in (where the black line on the ribbon cables are flush with the connectors on the boards), and still no go. Anybody have any experience with a non-functional trackpad?

Oh, wow! It didn't even take me an hour to break it again. Went and re-read threads on various forums, and people were having some luck with cold booting while docked. So I did, and yet again the keyboard ceased functioning. Despite having not even moved while reading/rebooting, I opened the dock once more. Of course, nothing appears to have changed, so I don't even know what to do at this point. The vendor has refunded my money, so at least I'm not out anything; it'd be really nice if I could somehow restore function, though.
I can get a replacement keypad/trackpad off eBay, but I'm concerned that my problem may be where the cables attach to the main board. Of course it could also be the ribbon cables themselves. Anyone know somewhere to get new cables at a reasonable price?
I've got the keyboard working again. Seems like once I plug it in to charge, the keyboard stops working and i have to go play with the cables to remedy that. that's only when charging with the tablet attached. haven't tried seeing what happens if i undock, then charge, then redock.
kinda surprised nobody's had any input... <shrugs>. and in regards to something i had said before, it seems i was a bit mistaken: i can order a replacement keypad, but not the trackpad. i'm wondering if i might need a new main board for this instead, though. would like to hear something out of someone who's replaced a board in the dock before i pull the trigger on one. anyone? anyone? Bueller?
new update:
had to set the dock to charge, and naturally, the keyboard didn't work. so i went and took it apart again. this time, though, I plugged the tablet in to the base prior to screwing everything back. I detached the cables from the mainboard, reseated, and checked-- no change. so I detached the mainboard cables again, and proceeded to reseat the cabling where the touchpad is. snapped the tablet back into place; lo and behold, I got a little circle on screen... hey! the trackpad's working!!! Excitedly, I screwed the screws under the trackpad button, and replaced the button, and proceeded to close the tablet so I could flip the dock over and replace the other screws/feet. Opened everything back up and unlocked the tablet and.............. <price is right tuba noise here> no trackpad. total freaking bummer.
I'm guessing now that maybe there's some kind of short somewhere. When I get to my destination this evening (or perhaps tomorrow, to be honest), I will further explore this new development. It's interesting at the very least. I do know the pad isn't totally dead in the water.
it's odd... charging causes the keyboard to stop functioning, and screws apparently cause the pad to stop functioning. very odd.
i've sat down and dismantled the entire thing. i decided to unplug the battery from the system board for a while thinking there might be some kind of situation where that could be helpful. let it sit probably 2 hours while i worked on something else. now i've reassembled, snapped it back together (but no screws yet), and the trackpad is working. has been working for the last hour, give or take. dock is down to 38% charge, so i'm trepidatious (is that even a word? lol) about which step to take next -- seeing what happens when i screw this thing back together, or try and see what happens when i attempt to charge it. i'll have to make some sort of decision, so once that happens, i'll post yet another update. hopefully a solve.
Problems with a dock? unplug that battery for a while!
I've rounded the last corner i think. i've got the charger plugged in to the dock as i sit here and type; trackpad still works too. all that's left is trying to screw it back together, so i'm gonna call this tenatively solved. because if i just can't have screws for some strange reason, i suppose i'm fine with that.
Still working... How does one go about marking something 'solved'? Ask a mod...?
