[Q] Horizontal lines on the screen - Nook Touch General

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...

*Please be aware that if you have rooted your device you may get undesirable results from daily use that I haven't covered here. That is a risk you take or something you have to put up with or solve/workaround yourself, or with your rom provider.*

Have a problem with your dock/battery?
Read THIS first.
My FOTA update keeps failing to install.
You have to fully return your device to stock (not just unroot). Use NVflash to do this. Then go to the asus ftp server and download any update file. Update your device using that file and this should allow your device to update FOTA properly.
Get a tingling sensation when plugging in a charger?
Flip the charger over and plug it into the wall so that the S in asus is on the side with the fat slot on the plug to fix. Seems to be a faulty adapter issue.
My screen isn't displaying anything:
Make sure none of the side buttons are stuck. Press them and make sure they 'click' ok. Force power off your device (10-12 second hold of power button, then release). Wait for about 30 secs. Then power it on normally (6sec power button hold and release). If your screen worked, then stopped, try discharging the battery to 0%. Then re-charging it. This has seemed to clear screen responsiveness for lots of people.
My dock battery is dead and it won't start to re-charge:
Try this tip HERE.
My speaker volume is stuck at a certain level:
Force power off your device (10-12 second hold of power button, then release). Then wait for about 30 secs. Then power it on normally (6sec power button hold and release).
My device/dock battery isn't charging OR my device/dock battery isn't holding a charge:
Make sure the charger is 100% clipped together properly. It's a very tight fit and may need slight force to snap together. Also make sure you have inserted the usb cable the right way up in your adapter. Sometimes unclipping, and re-attaching the adapter parts fixes problems (some come pre-assembled already so this may not be your issue). If your dock battery indicator doesn't ever go green after about 8hrs of charging (not for the first charge) then it may need RMA'ing. A normal charge of the tablet itself, from empty to full, should take about 3hrs maximum (not for the first charge).
My battery is draining very quickly:
Some apps run fine in the background, but there are others that may be 'keeping alive' certain functions, such as gps, sensors, etc. In order to get around this you can use free task killing apps from the market. It's recommended to be selective about which apps you choose to auto-kill. Don't just put them all on auto-kill (unless you are using a 'safe' option in the app) or your system may become unstable. If you have wifi on when you put the tablet in standby, it stays connected. If you then leave the network coverage area, the tablet will continually search for any network around it, draining the battery further. So when leaving home, remember to switch it off. Another possible cause of major battery drain is a badly coded/incompatible app. Get a battery monitoring app from the market and keep a close eye on the logs it produces. Don't watch every little blip/spike in the readings, try to take an average reading, over a few hours/days to get a better idea of what's happening.
Why isn't my device charging when I plug it into my pc?
It will only charge when the display of the device is off. And it is extremely slow and will only trickle charge. There are ways to boost power to your usb port, but the risks far outweigh any benefits.

My wifi signal keeps dropping:
Update to the latest firmware. Set your router/modem to a specific channel (set it to 1-11, NOT channel 12 or 13). Failing that, it's probably time to buy a newer wireless N router/modem (the TF does not support 5ghz, only 2.4ghz).
One of my speakers stays on even when nothing is playing from it:
Put your device into standby mode for 5+ seconds. Then turn on again.

My battery died very quickly while the tablet was in standby:
If you have wifi on when you put the tablet in standby, it stays connected. If you leave an area of wifi coverage, the tablet will continually search for a network, draining the battery.

You can modify that behavior in the wifi settings. Take a look at the sleep settngs.
I have not seen this mentioned so it probably is not too common a problem but my wifi was initially invisible to my transformer. Switching the channel from 13 or maybe 14 to something lower fixed the issue.

Yes, and I want to stress: wifi performance on standby is problematic and needs a fix. On the Xoom, wifi can be kept on when the screen turns off and standby performance is in the <.5%/hour battery use range. The Asus needs to have wifi set to turn off when the screen is off to achieve this kind of performance (otherwise, it burns about 3%/hour).
I'm hoping Asus is aware of this issue and will fix it soon in a firmware update.
some very good points, thank you
Touch screen stopped responding to touch
Brand new unit after about an hours use the touchscreen stopped responding to touch. It did this on Friday, May 13th, between Noon and 5pm eastern DST. The unit was working when shut of and was in a safe spot. I went to turn it on and no touchscreen. I noted the time as I think there may have been an OTA update then but I never saw anything on screen.
No monkey business, rooting, tinkering etc. Just learning about unit.
I have wiped the memory and cold booted several times, no change. I note that after a forced off the unit turns back on by its self. I saw earlier when I started the browser for the first time, the right 25% of the screen was over bright then went dark. Exiting browser, screen returned to normal and never saw this behavior again.
Screen may be somewhat dim now but cannot get past setup screen as only power key is responded to.
Already asked B&H for RMA but any magic gratefully accepted.

@easyrotor
Unfortunately it sounds like a clear case of a faulty unit. Don't know of anything that can help in that situation im afraid. Not what you'd want to hear of course, but at least it should be a simple exchange for a new one.

Good point, I'm not sure. I assuming that no matter what, the led on the keyboard dock would show just it's own charge.
Will have to monitor it for a bit and get back to you.
Hopefully later once Asus release another update, it will contain the dock battery vs. tablet battery (that got taken out from the .12 beta build) for us to monitor both.
just wanted to say that this thread is awesome...thanks so much for putting in the effort to document all problems/solutions that may come up with our TF's.

Transformer won't Charge
I received my eee pad transformer from hh gregg yesterday. When I opened the box I noticed that there was a scratch that appeared to be under the the screen. The scratch is very long, but also very fine and you can only see it when the screen is dark and you hold it up to the light. So I figured what the heck, not that big of a deal. However, when I went to charge the transformer, I cannot get it to charge. No light, no nothing. I've tried everything. Plugging it up to the computer, plugging into the wall, taking apart and putting back together, still nothing. I'm trying to figure out what to do. Does anyone know what could be causing this? Asus said I can send to them and they will look at it or I can send it back to the store, however, the store does not have anymore of the transformers in stock.

If you are taking apart and putting back together the wall charger then you likely haven't put it together properly yet; it will not come apart easily at all if it is fully together.
Try pushing harder than you think you should until the pronged portion is snapped in to place and you cannot easily remove it again. If it doesn't snap down, the contacts on the back side don't line up and it won't charge.

[Q] Boot problem I can't seem to find a fix for

I've seen a few people with the exact same problem around the web, but no one has ever posted a solution (if they ever found one).
The kids were playing Angry Birds on the Nook before dinner, when I went to turn it back on after dinner it wouldn't boot (was working when I put it down).
When I plug it in the wall charger the light is always green.
When I plug it into a computer USB port it is momentarily detected as omap 3630 instead of Nook Color like it used to, then windows reports that it's been disconnected.
It had been running CM7 for a few weeks off of emmc, but now I can't even get it to boot from a uSD card into CWM.
When plugged in (computer or wall charger) I can see the backlight turn on and off every few seconds.
No combination of button presses seems to have any effect (power, power+n, power+n+vol+, etc.)
Try holding the power button for a full minute... release and try turning it on again... see if that don't do it.
Thanks for your reply.
I wish that worked, but I don't even see the back light flicker on for a split second unless it's plugged into the wall or a computer.
It's a shame too, I got it as a Christmas present from the wife and our toddlers really loved to play the games on it. They keep asking where "bad birdies" went
Your problem sound similar to an issue I had with charging. I has a bad charger/usb cable. Its a known issue and BN will replace it for free. If you are registered, call BN support a request a new one. I have done this twice. Once when the end bent and a second time when I had a green N but not juice (just flicker and/or a 'plug in the charger' symbol). The NC requires more power than the typical usb charger/cable setup, thus spares usb chargers AND cables around the house do not work.
I hate to do this because it was so maddeningly frustrating to see the same thing posted in the thread about boot problems here and elsewhere, but it turned on today and I have no idea why.
I'd been messing with it for a few days and finally after an unsuccessful morning I left it on my dresser. I was in the kitchen making hot chocolate after playing in the snow with the kids when my two year old comes walking down the stairs with the nook and drops it at my feet. When I went to pick it it, it was in the process of booting. Whether he had done something to it or the short fall jarred something that was loose I can't say, but it now seems to be fine.
It had about 50% battery and the lights on the charging cord now respond like they should.
I have no idea what happened, but I wish I did so I could help others in my boat.
Still could be your charger/usb cable. When the charger/cable start going bad, it takes for ever to charge. Like all day just to get enough juice to boot up. If it dies again and doesnt reboot after its been on the charger for a few minutes or you're only getting a partial charge over night, its the charger and or cable.
It charged fine overnight.
There definitely must be something loose on the inside. If I give it a fairly significant whack (nowhere near a punch, but harder than a tap) it will reboot. I think it was a refurbished unit. The newer units seem to have serial numbers where the first four digits correspond to the year. The first four digits of this one are 2004! Looks like they never fixed what was wrong in the first place.
You just ran it too dead. It won't power on until it's established a decent charge first.

[Q] Nook Simple Touch not responding?

This was what happened - my N2T went dead, and I charged it up to 100%. It has previously been rooted with TouchNooter, and since my market wouldn't open, I overrooted it with TouchSalsa. Or so I remember. It may be different. I just remember that I used 2 different roots over each other. Didn't think anything would happen...
Anyways, all was fine and dainty with the N2T till the day the battery's charge was depleted. Charged it to full - Battery Indicator went green - and then proceeded to unlock it.
It was still responding at the lock screen, but once I unlocked it, it went straight to my Android home screen, and it just hanged. It has been showing the Android homescreen for quite a while now (probably due to the static e-ink screen, I believe it has died for a long long time), and nothing I do will make it reboot. I thought about forcing the battery out, but it was not user removable.
n2T-recovery wouldn't work too, as I can't make it reboot.
Any answers as to how I could make it rebott and/or restore the firmware like how I could force an iDevice into DFU mode?
Any help would be appreciated, as I imported this device into my country and it is not possible for me to send it back .
If anyone has encountered this problem before, feel free to shout out here too. My Nook Simple Touch has died for around 2 weeks now. I was hoping that the battery would run out and I could charge it but.... the battery indicator STILL shows green when I plug it in.
Also, whenever I plug it into my computer, the connected sound that happens when you plug in a USB drive just sounds - followed immediately by the disconnect sound. This happens in a loop until I plug out the Nook.

Same issue, i already open the cover and remove battery, the screen still display screensaver. Then I plugged NT into wall charger , then removed (to try make it reboot). Plugged battery into again but , plugged charger . But nothing happened, still the same.
Any other solution?
Just a hint: It appears that the Nook won't boot without the battery in.
I don't know if it's an interlock with the temperature sensor on the battery.
The chip that does the power management is capable of powering a CPU with a dead/shorted/missing battery.
Guess no one had a similar issue?
It is the same with my NST. It was bricked when I root it back to factory restore. The battery light is green, do everything you did to the battery, still no respond. I am not in the US so I can not take my NST to the local B&N store.
I get my NST only 1 week...

Dead Nook Touch Fix - showing green light on charge

Thought I'd pass this fix along.
I have a rooted nook that would not power up (stuck on last display screen). When I'd plug it in -- it showed a GREEN light (already charged). I tried all of the reset fixes (20 seconds hold, 1 min hold, wait a minute, 15 secs) -- nothing worked.
Finally, I pulled it apart using this tutorial on Youtube:
[Can't post link because I'm a newbie --- just search for "How to Take Apart a Nook Simple Touch"]
Very easy to do if you have a T-6 torx driver. I unhooked the battery. Held down the power button (white button if disassembled) for about 30 seconds to discharge the board. Then hooked the battery back up, reassembled, plugged in -- and it started charging (orange light).
It looks like the issue was -- the nook was registering the battery as fully charged -- and it was completed depleted. The above fix seemed to reset it.
Hope that helps someone.

However, for Nook to have such a problem and we need to fixed it in such a complicated way is not acceptable.
Fantastic. I had the same problem and now it is solved. Thank you.
After I bought a Nexus 7 my NST was resting for a while. Now, when I wanted to use it again, it was totally dead. Then your tip bring it back to life.
Thank you. When plugged, instead of "Charging (AC)" my nook was showing "Not Charging" in device info/battery. And in the end, it went dead.
After your fix, it works

It's now showing the "Your Nook's battery charge is too low to power up. Please wait 15 minutes! screen and a loading animation :good:
I was seriously worried.
This is really weird...is there any reason for this issue?
I am quite new to the nook in general. (Nook simple touch glowlight in my case.)
Maybe we can check for similarities and find what was causing the problem.
So what did I do to my Nook:
Rooted, Nook Manager
Nooks gapps flashed, market downloads work (search not)
Installed a bunch of apps
Installed a custom Launcher (Lightning Launcher)
Installed Swiftkey as a custom keyboard (needed several language charactersets)
Left Wifi turned on all the time
Used the feature to restore the glowlight setting after being woken up again
Used the setting to skip the lock-screen swipe
Used a custom screensaver/lockscreen text
Changed button links in the main menu (n-button) to adress the original home, as well as the custom launcher home
That's what I can remember :/
And as far as I can remember I had more than 15% of battery (at least).
With the 1.2.1 software there is an automatic shutdown that kicks in at around 20% battery.
It doesn't work very well.
It will also give you warnings when it's under 20% but plugged into the wall and charging.
Green light issue, fix not work
I recently got a brand new nook simple touch and after trying various fixes to try and start my nook up I came across this. I was hoping this would work but it is still on green when battery is plugged in and charging off mains. The light is also green when plugged into mains without battery attached. It wont go past the "Fully charge before first use" start screen and can't find any more information on what to do.
Any help would be greatly appreciated.
Thank you for the fix. It worked the first time I tried but after only one day the problem presented itself again and after that the fix doesn't seem to work anymore. I'm leaving the battery disconected a few hours in addition, to try if it fixes this problem completely (but I'm not too optimistic).

This firmware, does it still count even if you have rooted the device? If so, do you think a downgrade to 1.1.1 would fix the problem? It is rather funny that I didn't have this problem until a couple of days ago, even if my NST is only 2 months old!
Update:
It seems that my battery is not yet dead after all. It turns out that I was measuring it wrong (thank you Engineering degree) and now it reads 4.15V as it is supposed to.
So, that brings me back to the theory that there is something wrong with my software. Right now it can boot for a few seconds but as soon as it goes to sleep mode (either by clicking on the "power" button or just waiting), it freezes. I recovered the official firmware and the problem persists.
Thanks, this trick fixed mine too!
Does anyone know if this fix can be achieved by simply charging the nook for an extended period of time? I have the exact same problem but I'm not so sure about opening the back cover as it voids my warranty and I only purchased this device in early June, and the problem appeared by the end of June :/
I have to confess, I never did charge my nook fully when I bought it as recommended, and simply dived in to using it as soon as the battery had a sufficiently high enough % as I was too excited lol

However, for Nook to have such a problem and we need to fixed it in such a complicated way is not acceptable.

I find it acceptable. After all, if we weren't messing around with the devices in the first place, we wouldn't ever need to do this.
Plus, really, it's not that complicated. A couple of screwdrivers and it's open. I mean, should we expect it to open itself with a voice command or something?

Thanks, this method worked ok with mine.
HI dudes,
it seems I've got a similar problem, green light on usb and stuck on "YOur Nook has turned off completely"
I take it apart with no success ... any idea ? Mu NST is nearly brand new, ever used a lot ...
thanks
I had the same problem, the reason was completly dead battery. After bat replacement nook works great!.
When battery have to small voltage, noow won't start to charge. You can try with external charger, to bring battery to life.
I think some nooks was matured in stock, thats why battery was completly discharged...and wont charge with nook.
Nook showing green light, main board drain and nothing
My Nook shows the green light when plugged in either to the pc or wall charger. I've held down the button twice for 30 seconds and disconnected the batery holding the power button 30+ seconds. Neither worked. Any more suggestions? I do notice a slight flicker of amber whilst holding the button down with the power cord plugged in.
Any help would be greatly appreciated!

[Q] Nexus 7 dead?

I was on my computer when i remembered i has something written in my tablet's notes that was important. I took it out of my bag and noticed it wouldn't turn on, it was out of battery (hadn't touched it for about a week). I just plugged it in the proper asus charger and put it down and went straight back on my computer.
I decide to check on it after 2 hours thinking it would be near or fully charged. I pick it up and noticed it was on a blank back lit screen. I unplugged it and then the screen turned straight off. Wondering if it didn't charge at all i re-plugged it in. There was no google logo (rooted), instead it turn on with a lit black screen and off and repeating a few times and then small thin artifact pixels run across the screen (red, blue and yellowy colours) and then stay at a black lit screen like when i first picked it up. I had just noticed a small buzzing sound while this was happening and still does so when stuck at the screen. I'm pretty sure it was buzzing when i had found it.
I redid what i had done (unplug, replug) and watch to see if it did the same thing. It did. I tried to power it off while it was at the black screen and it did, but then it would turn back on and etc. Same if i tried to enter boot loader or any key combinations.
I've tried disconnecting the battery and reconnecting and same effect (tried it without battery attached also)
I have a feeling it is dead now and i have no other ideas (checked many forums but got nothing).
Any help would be appreciated.

It's surely hardware failure, have take some humidity or something like that?
Try press power for 60 seconds, if you wont see any Google logo there's some hardware failure you need to RMA ( http://en.wikipedia.org/wiki/Return_merchandise_authorization )
found the fix
I found away to fix my nexus 7. You could be right how it might have a minor hardware fault, live in australia in the high hot tropics (high humidity). I decide just to plug it into my computer usb charger instead of the proper charger since it had a lower max amp output. Against my ear, a much fainter buzzing is still heard but this time, there was nothing. No power, no back lit black screen, just a very faint buzzing. Decided to let it sit just to see what happens. After an hour or so, i decided to press the power button and noticed there was a battery charging signal. To my delight, I'm sure it was in working order now so i powered it on and oh how relieved i was.
I determined that my device might have had a small hardware fault that made it draw to much power from the 2 amp original charger and thus why the tablet could not boot up properly (from battery depletion). Either that or my charger could be bugged to. But the thing is, since it charged to slow from the usb, i plugged in the proper charger and it worked fine. Just have to try not deplete my battery i guess.
Thanks.
