I saw a similar question to this in the general section from back in July but no replies, so I will try this again here and see if anyone has seen this.
Sometimes when I try to power on the phone, the power button seems to do nothing. I press and hold or just a short press and the phone will not turn on. Then randomly it will just turn on. I have noticed in the past that unplugging the charger cable (either wall or USB) seems to help it power up after a few tries. The most recent time this happened, I pulled the battery and tested the voltage with a multimeter set to DC and it displayed the OL (over limit?) similar to what it does when the value is out of range. I tested all the combinations of the 4 connections and the same thing happened on all the proper +/- combinations. I set there for a minute trying to decide if I was crazy and when I tried it again, it showed 4.30V. I put the battery back in the phone and it powered right up.
Anyone else???

i rarely turn it completely off. generally, i reboot thru adb shell which avoids the issue.
on the few occasions i've turned it completely off, i have noticed that pressing and holding the power button didn't turn it on. i had to just tap the power button and it turned on.
i'd agree, there is something odd about the power on button compared to my ns4g and old evo ...
i don't think you're crazy, it is probably a consisently odd issue. hopefully the reassure helps!
HTC, intermittently brilliant.
Maybe something to do with this issue:

My 3vo was doin that also.the only way I was able to power on was through adb reboot bootloader then select reboot.after a few times of doin this it works fine

I too have had the same issue since i upgraded to CWM 5.0.2.0 don't no if your using the same recovery? I have also read in a couple of the development threads in the gsm section that holding the camera button whilst turning on works if it doesn't power on normally
Worth a try if it happens again.
Hey Y'all,
I helped a friend of mine root his NT awhile back, and it was working fine for months. I showed him CM7 running off of the SD card and he liked it, so I set it up for him on Friday. I did a factory restore on the NT, and he reentered his BN account info. I then booted off the SD card and everything was working fine as I could tell.
He brought it to me this morning and it won't charge. The "n" is always green when plugged up to the wall and it never goes orange to indicate it is charging. But when I attempt to power it on, it is always displaying the low power message and says to plug in the charger.
What I have tried:
-I removed the SD card, and it still won't charge... (not that it would matter).
-I have 3 chargers and my own NT. When I plug a charger up to my NT it works fine and the "n" goes to orange. But when I plug the same charger into my friends NT, the "n" is green and I can't get past the low batter warning.
-I have had my friends NT connected to a wall charger for about 3 hours this morning and I still can't get it to boot.
Any ideas on what might be wrong and how to fix it?
Thanks for your time.
I found this thread and tried both of the suggestions and my friends NT still won't charge or boot.

The same thing happened to my wife's nook this evening. I think the battery is completely run down, but won't receive a charge for some reason. Her charger showed green also.
I tried, removing and reinserting the SD card and also holding power for 20 seconds. I finally was able to hold down the power and the N button down for about 20 seconds. This did the trick. It showed that the battery was too low to turn on. After about 10 minutes, it booted.
Hmm, I get the battery is too low to power on every time I hold down the power button and the "n" is always green on the charger.
strandedinar, did you have the power cord hooked up when you held the power button and "n" button down for 20 seconds?
So connecting the STOCK charger and the STOCK cable and leaving it alone for an hour or so isn't doing the trick? That's really the most that many of us have had to do... No "n" button needed either.

Yes. The nook was plugged in and the "n" was green. The Nook wouldn't power on - My wife was convinced it was my fault for rooting it...
I left it plugged in like that for 20 minutes, but nothing happened when I tried to start it. The charging light was green. I finally tried the power + N button trick and then I received the notice that the power was too low to turn on. This was the first time I received this message. After this, the color of the charging light changed from green to red/orange and I could tell that it was receiving the charge. After 10-15, it power on and has worked normally since.
I tried every thing I could think of and google and nothing worked. I took it to BandN yesterday. They thought it was a typical issue that they see a lot of, but after 3 folks at the store couldn't figure it out, they called 1800 support. Support said it was a bad usb port and swapped it out for a refurbished model.
I still think I could have fixed it, but after a couple of days my friend was getting antsy for it.
Thanks for all of the responses.

How did you do that? I was trying to hold the buttons and never got anything.
My NT has no juice to boot, but when I plug in a power cord (stock), plugged into stock power charger, it tries to boot up. Power indicator does turn orange, but then it runs out of power once it starts booting and turns off. After a few second it turns back on, and repeats same cycle again. It never boots to the point where it can actually sleep, seems that boot-up process takes more energy than charges could give it.
Try charging it from your computer. Just as suggestion not sure if it will help.

Hello Galets, did you manage to finally charge your Nook? I have the same problem as you have - when stock cable and charger are plugged in - device tries to boot and screen shows up but due to lack of power in accum it turns off and in a few seconds the cycle repeats.
I hardly understand - how it is possible that having mains power plugged it - there is not enough energy to charge and do other necessary things...
---------------
UPDATE: problem solved. In order to solve it, I had to disassemble the tablet and unplug the screen cord, then I put the power cable in, battery charged up for about an hour or so, then I plugged screen cord back in and turned it on without a problem. The down side of early charge attempts is that tablet decided that I had 10 failed boots and it reset my previously rooted device. Now I have fresh and clean stock 1.4.2 version.

how did you unplug the screen cord? I've looked up how to take apart the nook, but I'm not sure which one would the the screen cord. Did you follow a tutorial somewhere, or was it easy to figure out once you opened it up?

ACL3, check this link: http://www.ifixit.com/Guide/Installing+Nook+Tablet+Display/11148/1.
I did not really follow the guide. I was looking for first two bolts to unscrew. The rest was quite simple but challenging - i don't usually disassemble things.
I did not pull out any of the buttons or battery from where they are and simply unplugged their connectors too - you will see 3 small foam rubber black box-like pieces (in step 9 they only marked one of them). There are plastic connectors under foam rubber pieces.
Be careful not to short-circuit anything with metallic tools.
On the attached image I marked the screen connector. I unplugged it by gently hooking it with two small screwdrivers. When putting it back I gently pressed it until I heard a click. And make sure those small slots on connector match with corresponding ones on motherboard.
Also, when finishing assembly I ran into a small problem with corner flap (which covers sdcard) - it did not want to smoothly slide in and out. So, pull it off completely and after putting plastic cover in place and screwing last two bolts, put it back - some small help of small screwdriver will be needed.
Hope my explanation was helpful

thanks, looks cool. I've never taken anything apart before and I'm afraid of short circuiting something. I think I might try this.
Hey, new guy here.
So about 2 weeks ago my EVO 4g LTE's power button started acting crazy. I would have to push it really really hard to make it turn on. Sadly it has gotten to where now it just doesn't turn the phone on at all. I have since downloaded an app from the market to use the volume keys to turn it on from sleep mode, but cannot turn it off without being able to turn it back on (the app only supports waking the phone up). I've taken it apart, cleaned it and still no luck. No matter how hard I press it, it just won't turn on. The button also no longer gives that slight "click" when pressing it.
I ordered a new button, took it apart, replaced the button and still nothing. It still doesn't even click. I'm wondering what the part underneath the power button is called. Would that be the power button flex cable. I'm speaking of the part the button actually touches to produce the power on/power off effect and the mild click it gives when pressed.
I bought the phone used and when I took it apart, it appeared to be tampered with at this same location. It looked like this section had a black coating on it where the power button would touch but had been rubbed/scrapped off, showing copper.
If anyone knows what this part is please let me know so I can order/replace it.
Thanks in advance
Hey guys.
So I've been having all sorts of issues with my Note (first gen).
First thing is the usb charging port went out; so I bought another chipset and replaced it.
Phone was charging= SUCCESS!!
However, I turned the phone off and rebooted it; screen wouldn't power up, but my home screen buttons did.
Now, the screen is black and neither the home buttons power up.
(K, I know the phone is powering on because it vibrates and is discoverable by PC)
So what the crap did I do? I just simply replaced the chipset, I didn't go messing around with other components...
My phone isn't flashed or rooted either.
Any thoughts?
(....and I don't have the $$ to send it to samsung, out of warranty)
It it were me, i would open it back up. Its likely the square push down cables that snap in. Either push them down to insure they are connected or unplug them and plug them back in. I have seen it happen many times. Just dont tear the ribbons themselves. Sometimes they connect partially and are not fully seated. Hopefully this helps you out
Hello,
I bought a Z5c in black a week ago. I did not use it up to now as primary phone, I was barely using it. The day before yesterday I was using it until Battery was empty, after that I was charging it. It was approx. 24h at the charger. Yesterday it did not turn on. I tried now 3 different Chargers (Original, 5 Port 2A, Surface 3 Pro Charger) and 4 different cables, nothing happens. The screen stays off, the LED doesn't turn on.
When it was still on I did not root / hack / flash the phone or whatsoever. I only installed some apps and played some games. It did not get in contact with water or sweat, it did not drop or something. It was mostly lying arround.
Do you have any Idea? I tried to push that small off button next to the SIM, nothing. Pressing On Button for 10s+, nothing.
Tnx already!
Cheers
Have you tried another outlet ?

Hey,
yes, even at home and at work. I also tried my Laptop, nothing happens...
I was just in contact with the Sony Hotline. The support asked me to press Vol+ and Power, but nothing happened. I also tried Vol- and Camera Button together with Power Button, nothing happens
Cheers
Small Update: Got it back from Sony, its working again. I got my phone back, not a replacement. The Letter with the repaired phone says nothing about what was repaired. But I can see that the back of the Phone was removed somehow as my attached protection foil has now some dirt below it that werent there before.
Lets hope that from now on my Z5c doesn't give up that quick any more
