Anyone else having this issue...
When plugging my phone in to the laptop no matter what mode I have the USB setting set to (PC Mode, Windows Media Sync, USB Mass Storage, or Charge Only) my touch screen becomes extremely buggy. The scrolling is very rough (if I can get it to scroll at all because it decides to select something instead), selects items that I'm not even close to touching, just doesn't respond to touch briefly, or locks up briefly.
It's instant too. As soon as I unplug the phone from the USB connection the responsiveness is back to normal, only needs a very light touch, and no jitters and locking. When I have the phone plugged into just a regular home or car outlet everything is fine as well using the same usb cable.
I get this in Windows XP, Vista, 7, Debian, and Ubuntu.
Edit: btw, I did the latest updates on the phone as well
Found over on the Motorola DroidX support forums an issue with the smart profile.
Turning off the smart profile helped a lot. I turned off the smart profile and powered off the phone. Disconnected the usb cable and powered the phone back up. Waited for the phone to completely load and tested the responsiveness and worked great. Plugged in the USB and seemed pretty good but with a slight hit on the sensitivity of the touch and needed a slightly more pressure. Went back into the settings and turned off the double tap to silence the phone (both smart sensor settings now off) and the phones responsiveness is now 100% back to normal in Charge only mode which was the worse mode to be in before.
PC Mode was about the best mode to be in before with the motorola MFC drivers installed but still took a hit on responsiveness. Seems like the Smart Sensor settings on my phone do not like USB. Hopefully that is fixed in 2.2.
Next question, now with all this fiddling around, every time I plug and unplug my phone even in charge only mode the verizonwireless media manager web page comes up on my laptop. Now that's annoying.
Found it. It was the MotoConnect software that was installed along with the drivers. Drivers are still installed but uninstalled the MotoConnect and the verizonswireless media manager page no longer pops up when connecting my phone.

The MotoConnect software puts a small system tray icon on as well. Right click that and you can turn off the VZW page if you want. Of course, un-installing MotoConnect completely works as well
New TF out of the box, charged (apparently), and it will not "turn on".
Note, this is a gift for my father, so my sister is in possession of the TF.
She charged it overnight and this morning, she pushed the power button ... nothing.
She went into a dark bathroom and could see the backlight on... nothing on the screen.
Went through the following:
1. Held power button down for 20 sec - nothing
2. Held volume down + power - nothing
Questions:
1. Is there supposed to be a light indicating that the TF is charging?
2. Is there a way to "reset" the TF?
3. Could the TF be in SLEEP?
4. The AC adapter ... is this 2 pieces? does the outlet portion separate from the cable portion?
5. Is this unit DOA?

Check that the 2 parts of the AC adapter are firmly pressed together. It sounds like it wasn`t charging.

She cannot separate the two parts. Is this supposed to separate easily?
Heard reports of damaged AC adapters. True?

Just tried to separate mine and couldn`t.There is a post about chargers but i`m afraid you will have to search for it. It was related to chargers not working i think (sorry i didn`t pay much attention as mine was fine)As far as i remember there are two different serial numbers for the charger. One was ok the other dodgy.
Sorry i can`t help more,
my tablet turns on as soon as I insert the charging cable... I don't need to press the power button
She tried a different USB charger, and no go. Still acted the same.
System did not boot...just a blank screen (visible in a dark room).
Sending it back to Amazon.
I have the same issue except that the backlight won't even turn on. Quite upsetting.
did you ever find a resolution?
Make sure you hold the power button for at least 8 seconds. If the battery is charged it should turn on. If it still doesnt you probably have a charging issue. (like a bad plugin trandformer). Try another power source. You can also hold down power and then plug in power cable and see if that wakes it up.

So I've made a bit of a discovery that leads me to think the unit is defective.
When I use the method you mention I hear a clicking sound which I think I've correctly identified as the tablet turning off. Once I hold the button 2 more seconds, Windows recognizes the tablet and has installed the proper drivers so the tablet is on at least at some low level.
The screen however remains black even in a dark room (no backlight visible). I have looked but I cannot seem to find an Asus tech support number for this tablet. Also because I can not get the screen to turn on I can not activate debug mode so I cannot get into ADB.
Try Nvflash, should fix any brick. If Nvflash doesn't work it's pretty much a DOA for sure.
Hi, I start this new thread as a new user and my first message because I'm really really worried about my samsung galaxy 10.1 tablet, It is a wi-fi only tab I bought through Amazon, and has just arrived to my country, Costa Rica, so, as any normal person, I opened the box, readed the manual and turned it on, and started checking everything in the tab, and when finished, (because I don't have wi-fi yet) I turned it off, and started to charge it with the factory charger (AC conector) it has been 5 hours since then... It has not turned on again, no matter if I press the On button 30 seconds, nor turning it on conected to a computer, or to the AC, or without anything, so I called support, and they said the same thing I was expecting, charge it and see what happens, and nothing happened, I'm really really worried about my tab, 600$+shipping is a BIG amount of money to have invested, the computer is brand new, as you will buy it from the second link availabe in amazon when you type samsung galaxy tab 10.1.
Can you help me?
Tab does not turn on..
What finally happen did it turn on...If not there is a why to reboot it by holding the vol. button and the Power.
Hope it went well, don't give up..
That is why I made this thread, I already tried the volume technique, with +, with -, with both, with + and shaking, with - and shaking, and all those with also touching the screen, an nothing!!
when you turned it off and plugged it in to charge, did you notice anything appear on the screen indicating that it was charging? Normally when turned off and plugged in a battery will appear on the screen. even if the screen turns off you can touch the power button to show the battery again.
If no battery ever appears, then it looks like you were not receiving a charge in the first place so the tab can simply be dead of juice.
Yes, the first time I turned it on I saw the battery, but when I turned it off, I never saw it again, even in this 10 hour period that has been charging on different outlets to see if the outlet is the problem.
Even I used a pencil tipe voltage tester, that tells if an outlet has voltage current, and the voltage could be felt around the tablet when charging.
But the screen does not turn on when pressing the button, nor touching the screen.
as a test, use just the usb plug and connect it to your computer. it shouldnt receive alot but see if that will initiate the screen turning on displaying the battery.
No, it does not turn on even when conecting it to the computer, it appears a message of no controlers found in the computer, but the divice does not turn on at all

idk then man, it could be the wire or it could be the tab itself
Besides something wrong with the GTab, I guess it could still be a defective cable.
Yes, it could be a possibility, that the wire is bad, but also, I can mention that in the time it was on, and working, I exchanged a couple of photos for my wallpaper, photos that I took with my camera long ago, so, if conection means, the cable I think works ok.
this happened to me.. tab is finished, send it in for repair and you will receive a refurb....

Did you press power and volume down at the same time for at least 31 seconds for samsung logo to come on?
Sent from my GT-P7510 using Tapatalk
I've tried with the volume key and the power key at the same time for almost a minute, without being conected to the charger, and being conected, also tried conecting it to the computer, and downloading the drivers that samsung offer in the support page, and samsung kies, but they don't recognice the device, when checking the hardware of my computer, I see inside the tab of "other devices" one called APX that I know that is my tab, and says no controller is assigned to it.
Mackie, yesterday (today) I chatted with a support agent of samsung until 2am, trying to see for a solution, but he couldn't find one, so, we ended up in making a request for service, to use the warranty for them to repair/give another machine to me, but, I don't want to do it, because, it would be enormously expensive for me (100$ for a Costarrican is very expensive) so, I'm trying to find a solution to the problem before I send the tab to the US with a friend that lives there, so I can use the warranty, but that courrier charges would be really expensive for me.
In summary, I'm trying and trying to look for a solution, testing your comments and suggestions, and also at the same time looking for myself for an answer.. before december 8, when I plan sending my tab if anything works.
Once, this happened with my nokia e71, but because it ran out of battery, and won't turn on again, but... cellphones are easy, you can change the battery, and actually, it worked, and when I had time to take him to repair, they checked him with the old battery, and it worked again... Tabs are horribly sealed tight and I would lose the warranty if I try to open it to change the battery, and it might even not solve the problem!
i don't know if this would help.
I had the same situation and i thought mine was dead.
I pressed the volume button as long as i can. Took about almost a minute.
Sorry if this doesn't help
people please read previous comments, Coliner has stated numerous times in different posts that he has tried the power+volume method and has had no luck so please stop suggesting it
Coliner, the only other thing short of paying the money for the exchange/repair is to attempt using a different cable. you stated before that you used both the usb partial charge and the actual A/C charge method and have received no results. The only thing I can suggest is to try a different cable, if anyone else you know has pretty much any of the galaxy tab (7", 7+, 8.9", 10.1", 10.1v) then you can attempt to charge it. Or hell, see if any store has any of them on display charging, explain your situation and ask to let you give it a shot and if it works buy the cable from them if possible.
Short of prying the thing open to play surgeon, these are your only options.
NyPlaya, today, I'm going to the capital (the only place you could find something similar) and look for stores with tablets, and also directly to a samsung store, ask for a charger, and to see what happens, and try again to turn it on at my house, I've let her charging for 2 days now, continuosly, lets hope it worked!

I re read your post and i think we missed a big clue. You said you can see APX device in control panel. Apx is nvidias debug mode and in this mode (usually reached via power and volume up) the screen is blank. it is waiting for nvflash command. Check this thread for more info http://forum.xda-developers.com/showthread.php?t=1324461
So wonder if volume up button might be stuck

Well, I tried the procedure, and got to step 17... How do I run that command, how, where? so I then uninstalled the controler, and now not even the APX error appears, and tablet is still dead!
Also I went looking for chargers in stores, and they did not have chargers! so I couldn't test it!
I was searching in other forums and found this other clue:
Taken from http://www.htcmania.com/showthread.php?t=274687 post #14:
"What you run "dead" after having it at night charging, is something that unfortunately is still quite common. It happened at the beginning and pulled by soft reset, ie power button volume button -. It has happened a few times and this has been solved. I think it is related to removing the charger. Unplugging from the wall and then the tablet does not usually fail, but if you disconnect first tablet, it "dies." I tried also to turn on the screen before unplugging and so has not failed me to unplug the tablet first. Clearly a bug, I do not know if Samsung or Honeycomb, but obviously it is a pretty annoying bug. regards"
I remember I did that same thing! because my tab was conected to the PC, and I discovered it was not charging, I conected her to the AC in the wall, and without taking the 30 pin conector out, and boom, never again it has turned on!
I continued searching and found another method, power button plus volume- 10 seconds, release and volume + for some seconds, then conect to PC, and the driver appeared again, in this case Nvidia USB boot recovery
I continued to try the method shown to me by animatechnia, and typed nvflash --bl bootloader.bin --go, it says then:

READ THIS, IT'S HAPPENED TO ME
Shortly after buying my tablet, before rooting, my tablet was charging and would NOT turn on. I read somewhere to do this:
Put your finger on the screen while holding the power button for as long as you must.
Don't let go til it comes on.
Edit: best of luck if that doesn't work. Things like this suck.
First time I tried with the finger, I forgot to disconect it, so, my pc started making sounds of conected device, disconected device, just like an USB stick, then I took the cable off, and tried for more than a minute both finger and power, and nothing happened
My nook is rooted. I nearly always use it plugged to the wall outlet to save battery live. I use it mainly to read pdf files using "OfficeSuite". When I start up my nook I activate to the app "Nook refresh" and "Smart Rotator"(to use my OfficeSuite in landscape mode).
Some days ago I installed a screen rotator app (from http://forum.xda-developers.com/showthread.php?t=1678431) and couldn't use it, so I uninstalled it. I do not know if this can have any relation with the problem that I am having with the screen.
Some days ago my Nook screen was perfect, no strange thing.
But one day I noticed a horizontal line (from the usual perspective, with the "nook" button below) that was dark/white (that is when the background is white, the line is black and viceversa). I did not give it much importance.
Another day, while I was reading a pdf file, appeared another horizontal line.
Today, while I was reading a pdf file, appeared another horizontal line.
That is 3 lines for now.
What could it be? Do you have any idea to solve this issue?
Thank you.
If you power off and then power on again, do the lines go away?
I would not recommend using the NST plugged in at all times - I think you will do better to let the battery cycle.
E-ink is attracted to and repelled from the screen by electrostatic charge, as I understand it. So if there's anything like a power surge or other mechanical issue affecting your unit while charging, possibly you could see an artifact in the display?

I did this with the wall outlet disconnect several times, but it does not work. The lines are there.

Why do you think that? I do it because a read that when the battery is fully charged, the light turns green and not continues charging the battery, so I suppose that direct energy is feeding the use of the device instead of charging my nook.

No, the only image that appears on the display when I power it on is a SD CARD image informing that there is a sd card.

They're probably permanent if after unplugging, powering off all the way, then powering on again they persist. If your device is still under warranty, I'd suggest resetting it to stock and getting a return.

I thought about that a little more. On the NC, if the device is plugged in, the screen tends to behave very strangely - detecting nonexistent touches or accepting input, but then repeating it (fast page flipping through a book, rather than turning one page.)
The charger on the NC and NST is not its strong point (the NC in particular, but I've never liked the fit of the NST chargers much - on both of my devices, they tend to seat at an odd angle and need to be pushed a bit to seat correctly) and I've always wondered how well the rest of the device is actually isolated from current when it's plugged in.

I've just had the same happen to my NST. First a single horizontal line, now two.
Did you ever resolve your problem?
Same here. One, two, three and yesterday appeared the fourth line! I have the Nook more than one year. I noticed the lines everytime after charging, so it could be connected. Discharge, charge, reset, nothing helps. When I will buy myself a tablet or a new reader. I will open it and pay with some display connectors.
I ended up returning mine to B&N as it was still under warranty.
But I'd be interested to know what you find if you take yours apart. It kinda sounds like a loose connection somewhere...
