[Q] NC not booting unless plugged into computer? - Nook Color Q&A, Help & Troubleshooting

Rooted and using CM7. Not a big annoyance since I always have access to my usb cable to plug it in but is there some way of fixing this?

Can you be a little more detailed, do you have any other problems like a faulty power button or does everything else work fine. If that's the case you should probably do another cm7 install by re downloading it.

Don't know how to be more detailed then the title.
Until I plug the NC into an outlet or via usb to my computer it will not turn on. When on however I can put it to sleep and hit any button to wake it.
Not really that big of a problem but just wanted to see if it was a fixable bug or something.

It's easy to be more detailed THAN the title!
What happens when you hold the power button for 5 or more seconds?

One of the bloggers on Droiddog.com had the EXACT same question. Yes it's possible... read her method here:
http://www.droiddog.com/android-blog/2010/06/nexus-one-power-button-failure/
Basically:
Plug the phone in– USB or AC works fine.
Wait until the charging light comes on.
Remove the battery, while leaving the phone plugged in.
Replace the battery.
After about 3-4 times, the phone should boot.
i need to know if i can turn it on via usb command, ive already called in for the device swap.

[Q] Bricked or jusr dead?

Hi all,
I got a Samsung Galaxy S (i9000) from a friend who wanted to toss it away since he says it is broken.
I want to see if it is or not.
When I try to turn it on, complely nothing happens. When I put the charger in (or the USB cable fot that matter) a battery sign appears with 5 dots under it which move from left to right. When I try to switch the phone on nothing happens
When I wait a while, the screen goes black. When I try to switch on, nothing happens.
When I push the home button, the green charging battery appears again and the back an menu button light up.
A factory reset is not working at all. Can it be that the power button is broken??
Any help would be greatly appreciated!
Regards,
Vincent
Fixed it!
Hi,
I was able to fix it.
Thanks to this sticky: http://forum.xda-developers.com/showthread.php?t=1134975
This is what happened:
I tried just about anything, nothing worked. Then I saw a reply in this thread someone mentioning you should plug in the usb cable, push both volume keys and then maybe it could work. But of course, mine didn't.
Then I started experimenting, what did work was this
- take out battery
- connect usb cable to laptop
- push volume down + home simultaniously and then put battery in
Now i got into download mode (yellow robot and triangle + warning not to turn off target) and with Odin I was able to start the phone.
I then found out that the power button was indeed broken!
Phone works like a charm. Only thing is when I have a dead battery that I have to use Odin to start the phone. I will seek for a way to fix the defective power button.
Hopefully it will help other people with this problem!
BTW, thanks all for all the help

[Q] MT4g Not Booting

My MyTouch 4G powered off one day and won't power on anymore. I've tried pressing the volume down and powering up at the same time, but no response from that. I've checked and made sure that the buttons are fully functional. When I plug the phone in to charge it or to connect it to the computer, the back, Flash LED lights up. Help please?
I've tried looking for other posts and seeing if anyone has had problems like I'm having and there seems to be no one else. Thats why I'm making this post. Anyone know how I might be able to fix this?
The phone was running the stock MT4G OS. I tried establishing adb connection but nothing happened.
Thank You!
Your power button might be dead.
Or you have a brick

So, the phone's dead now? There's nothing I can do about it?
Connect to charger, then put the battery in.
Try several time.
If it's power button failure - this might bring it to life.
If not - there's nothing you can do, give it to someone to fix.

Nexus 7 won't turn on

It seems there are already several threads about this seemingly common issue with this tablet, but I've tried the normal checks and still can't get any life out of my dad's nexus 7 whatsoever.
I've found several threads stating it's just a loose battery, but in this case it isn't. I've checked absolutely every single connection I can get to without removing the void if removed bits, and can't find anything suspect. However it still won't turn on, won't charge, etc. It's not a faulty charger or cable either, we've all got android in my immediate family and we can't get any life out of it with any lead or charger. It was simply working one day, it was turned off the way it always is once my dad had finished using it, and now it simply won't come back on again.
I also saw some people say to get it into bootloader mode by holding volume down and power straight after plugging it in, but that too does nothing whatsoever?
Does anyone know of anything else I can try, short of sending it back to Asus?
How long have you had it?
This sounds like something that should be addressed as a warranty situation, as anything else may be kludgy at best, and may fail again just after your warranty runs out.
I wouldn't really waste any more time.
JMnsHO.... :beer:
My dad has had it about half a year, maybe a little more. But he bought it from Comet, who no longer exist since they went under just after Christmas, so he can't return it to them now. Unless it'd just go straight to Asus instead.
I had exactly the same issue.......I fixed it by disconnecting the battery and reconnecting which by the sound of your post you have already tried.......you should be able to go straight to Asus for repair.......good luck....
Sent from my Evo 3D GSM using xda app-developers app
After probably 30 days it would need to go back to ASUS anyway.
As I'd said, I wouldn't waste more time fussing with it.
They'll take care of it and still preserve the balance of the warranty.
If you messed with it too much, you may find yourself with none at all, and on the hook for the cost of the repair.
Make the call.. :thumbup:
Well I've not done anything that shows I've been in there like I say, so any manufacturer warranty should still be intact. Same goes for the software too, not rooted, on the standard rom and kernel, etc.
I was just hoping I could fix it for my dad without having to send it off.
Not yet, but anything else would be more 'intrusive'.
How long have you been working on it?
Not long, only 10 minutes here or there to see if I could find something loose. I might check the voltage of it's battery to see if it's flat, and also check to see if any power is getting to the battery while charging. That'll help prove if the battery or it's control board is dead or not.
Just checked the battery over. It's a 3.7v battery according to the label, and my multimeter shows 3.7v, so the battery is fine with no loose connections. At the connector for the power button ribbon cable, I get the 1.8v that should trigger the tablet to power up when the power button is pressed, and the power button is good too, only showing continuity when pressed. Again, no loose connections. But the bloody thing still won't turn on.
Any more ideas?
When you say that you "tried all the normal checks", does that include all of the fixes listed in the sticky dedicated to this subject?

Yes, your thread is about a faulty or loose battery. As I've said, it's not a loose connection and I've now tested the battery too. Unless you can think of something that I've missed?

That sticky has all of the well-researched methods of addressing the collection of related issues (won't turn on/won't turn off/battery status). It is not only about a faulty or loose battery - there's much more.
Give it a read and let me know if there's a fix in there for you.

I have read it all, and unfortunately there's nothing in it for me.
If your able to get to bootloader maybe try to power off then let it charge for awhile then boot, or hold the power button for a good min
It won't turn on at all, so it can't get into the bootloader. Tried already.

I know you tried almost everything in the box, but when you plug it in the wall and press and hold the power button do you see the screen light up but still black?
If yes ( hopefully ) then continue holding power button then press VOL down til arrow pointing with START appears. Cycle through with VOL down til you see power off and select.
After it shuts down unplug from wall and replug and let it sit for a long awhile
If this didn't help at all sorry......good luck....warranty?

Nothing happens whatsoever mate, even while plugged into the charger. Tried the original charger, my s4 charger, my old HTC chargers, from the pc via USB, etc. None of them make any difference.
Got a feeling it might be the motherboard, as it has power. Can't be the display since I've tried getting a logcat from it after holding the power button for a while to make sure it would have turned on. ADB just kept saying "waiting for device" as if it wasn't plugged in, confirming it isn't even turning on.
Can anyone think of anything I've missed?

Can the pogo pins be used to charge? bit of a long shot and you`d need to buy/borrow a dock of some sort. Definitely sounds like a hardware failure issue.

It already seems to be charged though.

Rooted now frozen in Installing Screen. Cannot restart.

Few weeks ago I found wife's old NST (non-glowlight model) in working order and decided to root it. Rooted it, played around with it. Wasnt too impressed, so just threw some ebooks for my kid to read while on vacation. Left it on my desk for a few weeks as I got busy with work. Today I picked it up as my son's vacation is next week and it's frozen on the "Installing... A new software update is being installed This will take a few minutes" screen.
I mean I googled for several hours, the hold the power button for 20 sec method....the hold the power and the "n" button method, I charged it, indicator light is green. I even opened it up and pulled the battery cable..... NOTHING WORKS...]
Please help. So weird...it was working fine and now frozen.

The real question is whether it is actually still on or off. What happens when you connect it to a PC via USB?

Only the green charging light goes on. I do not hear the little sound it should make when making a successful USB connection.

And I guess the drives don't mount successfully. Well, disconnecting the battery should certainly turn it off. If reconnecting makes it start spontaneously (should not), you could prepare a Nook Manager sdcard and insert it before reconnecting the battery. But this sort of sounds like the ability to boot is lost. Hmmm. I'll have to think about it.
unfortunately disconnecting the battery does not appear to do anything... screen continues to show that 'Installing... " screen. Hoping to get this thing figured out with someone's help

E-ink screens stay the same unless there is a new powered input so it could simply be off, having run the battery down completely during an update (maybe Wi-Fi was left on? That would run down the battery for sure). So if all of this happened during an OTA update, it could be really messed up
When my NST is off, plugging in the power pack turns it on. Initially the LED is green and then changes to orange as charging begins. I'm assuming nothing happens when you do the same. If the OS is scrambled from losing power during an update it may not be able to boot. You didn't say how you rooted. If you used Nook Manager you could try putting in that card and then connecting to the power pack, hoping for a boot from the SD card. If you got that far you could try a factory reset.
My power button is sometimes really cranky and a few times I've run through my entire stock of words that do not come from children's books trying to get the device to turn on. So you might try, but if it's really off the power pack should turn it on.

When I plug in the power cable the light just becomes green it never (not even for a split second) turns orange. Yes, I'm rooted using nook manager. I just suck my Nook Manager SD card in the nook but nothing happens. I'm not sure what you mean by using the power button, in my original post I mentioned I tried the power button with no luck. What do you mean by power pack?

Power pack = charger.
So if the Nook is actually off, attaching the charger with the NM card inserted should make it boot. Did you try the procedure in the link above?
Just tried the procedure of unplugging the battery, holding the white power button for 30 secs, then connecting battery and connecting to charger. There is a split second orange light and then green the first time i plug it in....subsequent plugging results in always green....the issue with the frozen screen on "Installing" remains. Tried the holding x 20 secs method to promt a restart....nothing.... what else can I do?

If the battery is actually "dead" (not impossible on these old devices), the NST will not start, even if plugged in. Do you have a voltmeter of some sort to check the battery? If it's actually charged, it should show a solid voltage. If not, that may be the issue. If the battery is actually charged then there's a pretty serious issue that can't be fixed without access to the OS by ADB, or the ability to boot from the SD card. Beyond my "pay grade", at any rate, I'm sorry to say. There are batteries available online but the price may not make sense.
I don't think it's a battery issue. I had another NST with a good battery but a bad screen (lines all across screen) . I fully charged it using the bad screen reader and used the battery from it for the frozen nook... no luck.. oh well... I guess this is a paperweight now... thanks for your help everyone.
