[Q] Buggy TF Bad Touch Screen

After all the excitement of my TF arriving I fired it up to find that the touch screen has issues. Say you are in landscape mode, about an inch from the top there a half inch wide strip that runs all the way across the screen that will not respond to a finger touch. I either have to have it docked and use the mouse to do anything in that area or turn it to portrait to change the orientation so what I want to touch is not in that area. That same area of the screen is dead in portrait mode too.
Also, it won't charge through the USB ports. I was in on the TD sales so a return is not possible. I'll wait till more are available, buy another from a different local vender then do a swap and a return.

when connected to your PC,it won't charge through the USB port unless you turn the screen off

I left it sit with the screen off for over an hour and the battery level dropped. I also tried it completely powered down and the battery level didn't change.

Wasn't that by design? I seem to remember hearing that the power supplied via USB is so little that you can't charge there, but have to use the a special cable?

It was like that outa the box. The first thing I tried to do was drag a few icons to the removal area. As soon as I slid it up the screen and hit that area I couldn't drag it any farther. It was like I took my finger off the screen. It took me a while figure out what was going on.

Hmm... Now that you mention it I think I read that somewhere too...... Time to do more research.
The problem I have right now is I am leaving for camp this afternoon and I have no electric there yet. So I guess I better have it fully charged before I leave. It's going to be tough getting a whole weekend out of a new new toy.

One more thing, I left my wall charger at home so I borrowed a coworkers Thunderbolt wall charger to see if I could top it off before I left for the weekend. It won't charge it either. So something must be pretty special about the TF's wall charger.

Although the problem seems different from mine, it does show ASUS has some quality control problem with the touch screen no TF. See this thread: http://forum.xda-developers.com/showthread.php?t=1068569

I had exactly this with my first TF, except it was a 1/2" wide strip about 1" up from the dock connector. Factory reset and unplugging from the charger had no effect. Asus was willing to do an RMA but I returned it to Newegg instead and hunted for another one.

Ok, after reading all the new posts this morning from a lot new purchasers I guess I am not the lone ranger with some issues. I guess that is to be expected for us early adopters. I'll get this unit switched out when they become more available and I'll just deal with the screen problem till then.
I love the TF. The screen is beautiful, seems very responsive in the area that it works and is extremely fast. When it's hooked up to my Bolt using 4G it surfs amazingly quick. I can deal with a bug or two for a while.

I've got the same thing but about a third of the way from the bottom of the screen. It doesn't respond to touch when I lay the tablet down, but when I hold it in my hand it will respond better but still not great. Strange.

Upgraded Keyboard Dock now won't charge!

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

It was hard until I read goodintentions' directions in his post

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

[Q] screen activation

1st, I'm spanish I'll try you understand what I say
I see that the tablet with the screen off (locked) can be activated without pressing the power button. Only need to put "near the dock"*
*making like you open the tablet+dock, but is not needed that the tablet was connected with the dock, I dnt know if someone else was noticed that... but I'm a bit curious about that and i want to know how its work? (magnet?, gyroscope?, magnet+gyroscope?) if someone knows it
and I say it to other people that dnt now this, THANKS
SOLVED MISTERY!
Like some says here its a magnet near the backspace key, exactly the "¿/¡" key
here is a really good cover mod idea: http://forum.xda-developers.com/showthread.php?t=1507548 thanks to MrNago

nobody has any idea?

I think there is a switch in the hinge maybe? Seems that would be the easiest way to have the screen turn on while opening the lid while its on the dock.

I test one more time and I noticed that the system is only at the right side of the tablet and dock, like u see in this image. And its not needed any contact, but it need tablet and dock really near.
I think is a magnet system, but i havent any magnets at home to make a try...
edit: i have an error in the image, looking the camera i can see that the tablet is in the wrong side, we must see the camera down. Not at the top like in the image xD

ww.youtube.com/watch?v=k-6dKsGJ4VY
I see nothing in this disassembly to make this activation, this is curious, i want too know how it works

turning on via opening.
i tried looking using a magnetic viewer screen there are several places in the screen and in the keyboard that show magnetism, on the screen the two speakers are the main places and in the keyboard below the backspace key is quite strong as well.
i tried replicating the action using a strong magnet but i could not get it to work only when help above the keyboard does it work so there may be more then one place it looks at, i will try again when i have more time and then post results.

Interesting discovery! I don't thnk anyone actually tried this, though many speculated there were magnets in the base, many users said (and I agreed at the time) that the mechanism to wake the device was located in the hinge, though having a function like this actually does make more sense than an actual hardware switch that could fail at some point.
You should make a video and I will add this information to my epic noob thread!

thanks for replies, i tried with a small magnet without results, and try in other positions with the dock and negative results too...
I'm sure that the magnet of the backspace key its the "switch" or one of them, they are 2 maybe....

Guessing here, probably not just a magnet, maybe even an RFID chip of some sort..

Its a magnet that does this. Don't doubt. Believe. Removing the magnet and putting it back in is part of my hard drive soldering procedure.

it is a microswitch in the hinge, all experimentation I have done supports this, the only thing left for me to do is pull apart my dock and take high res pictures of the microswitch seeing as you all seem to need proof of it

Stevie, i did think so as well, but the device will wakewhen placed on the dock and removed even if it is not affixed in the hinges and even if the hinge does not move, i don't think you are getting what poster is saying, i will make a video myself and post to demonstrate.
HERE
Thereis also probably a switch in the hinge as well for sure, but this does seem important information, wonder what the mechanisms in the body of the tf are..i enjoy solid state switches like this

Oddly enough this is confirmed using Paul's ICS and my dock not connected. Totally bypassed the lockscreen. Held it as close as I could for about 5-7 seconds then on came the screen. Tried this at least 10 times (five of which I just was amazed) and everytime opened right up. Nice catch:thumbup:

You guys are right, there is some kind of magnet. For those that doubt it, like I did, try this:
First off, undock the tablet, so that you have the 2 items apart.
1. Lock the tablet, so that the screen is off.
2. On the dock, rotate the hinge outwards, so that you can put together tablet+keyboard without docking.
3. Actually put them together, so that their position is exactly the same as docked, except they aren't.
4. Screen should turn on. Mine certainly does!
Edit: as you can see, there is no connected circuitry between them and the tablet is waking up. Don't know about locking though, but I hope this gets things clearer and Modding nearer!

This is the same way to unlock that Im saying since the first post. Only need to test to know what kind/power/number of magnets or "sensor" is needed

[Q] Dock to Tablet connection loose

Hey everyone, Since i got my transformer I've only had one thing bug me and that is the left bracket on the dock holding the tablet in place feels loose and wiggles around slightly even though it seems to click in place. where as the right side is fine.
I brought it second hand for cheap so this kind of this was expected. Just wondering if anyone's having a similar issue.
Cheers

thats normal all the connectors are a little loose my tablet sits at about a 2-3% angle

Wireless charging quit

After opening the back of my phone and taking it apart to get a stuck sim tray out, my wireless charging quit working. What could I have done? I did remove the battery, but I made sure to plug everything back in. Was there a connector on the backing that I missed?

Make sure to press the back down toward the upper middle of the back (all around the "S" in Nexus). There's a clip there that must fully seat, or the wireless charging connectors won't make contact. It's pretty common to miss that one.
Note: I think it's actually a bit to the right (or, a bit "beneath" the letter S, when held in landscape), but I can't remember the exact location, so just press down all around that area.

After putting my phone back in its Spigen case, I seen a couple clips came loose. I pulled it out of the case and made sure they were all seated and tried it on the charger again without the case and it still isn't working. I really don't want to pull the back off again but it's looking like I might have to, otherwise I gotta see if I can get the phone replaced through my carrier and hopefully they don't find out the back was off.

Judging from the picture in that link, the clip I was talking about seems to be directly across from the flash, just to the right of center (as you're looking at the back of the phone... so, just to the left of center in that picture), so that's where you want to press down to make sure that clip gets seated. (I guess I didn't realize it was that far up.) You can see by the proximity of that clip to the wireless charging pins how not being fully seated will cause the pins to not make contact.

OK, I didn't realize there was a clip there. I'll give it a try. Thanks.

@jt3, thank you so much. That fixed it. Working now. I'm having some display issues though, don't know if it's related. The whole screen becomes a bunch of lines but goes away when I press the power button. I've seen it before and it might be Multirom related but I'm not sure.
And thanks @Henrock11 for providing the link to the picture to figure this out.

No problem. Glad I could help.

Glad to hear. Like I said, it's VERY common for people to miss that clip when replacing the back cover, so I figured that was a good place to start.
Just out of curiosity, what prompted you to remove the back cover? Button Rattling? Weak Vibration?
