PLEASE TRY TRY if who is using SAMSUNG device (especially Galaxy Note) !! Thanks !!
I am out now so not able to test this.. but I guess it happened with me (not sure) when I was flashing my rom, my Note is turned off and it was plugged in USB and charging indicator was on... and i couldn't start the phone coz it was charging... but I really didn't give it any attention... maybe its in purpose or a bug.. but for me it was no big deal... I may try it again to confirm
Most of the Not-Wakeup problems are related to the wifi,tun off the wifi and try again that way.
it is the same with my old Streak. I think it's pretty normal
I wait for the charge battery to show up then I hold the power button for two seconds then screen goes blank and it boots.

when the big battery charge icon shows up, i can turn my device on by holding the power button for 5 seconds or so.
Has always been that for me, cant start it when its charging, dunno why its like that.
send it to samsung and reclaim a new one?
After owning a Galaxy S i9000, an S2 i9100 and now a note I can safely say this is normal behaviour for the Galaxy line, never once been able to turn any of them on properly if already being charged.

I have to wait a few seconds after the charging icon shows up before it will power on.
as long as it powers on its no problem

i've done the JB original ota update.
one day, when i was calling my friend, the display become black and never turned on. if i press the power on button, it vibrate.. but i don't see anything..
i tried to repair software with pc companion but... nothing.

Press the power button and volume up button for 20-30 seconds untill it has vibrated 3 times.
Turn it on.
If it does not turn on, plug it into the wall charger and leave it over night.
In the morning try to turn it on, if it doesnt then it is fubard.
Also, when you say "One day it just didnt turn...." what had you flashed to it? Have you rooted it? Have you unlocked the bootloader? Which ROM are you on?... All usefull info for people trying to help

Did you try to turn it on after it vibrated?
If the LED is green whilst connected to the wall charger, try to turn it on again.
Try the power and volume again.
If you ring the phone from another phone does it respond or is it unavailable
1 put wall charger
2 presset power + vol up
3 vibrate one time.. then 3 times.. led RED. if i dont press anything became green. if i press power on remain green.
don't boot anyway..

The phone boot... the touch work... but the screen is black..
Sounds like a hardware issue. Did you drop or damage the phone just before that happened...
No drop.. no water.. just like i said... after finished a phone call,the display was black and never turned on..
Take it back to the shop. If you have not modified it and it "Just Happened" they will have to replace it.

[Q][Solved] Htc One does not respond after charging over night

When I disconnected my phone from the charger this morning the LED did not shut down. The phone does not respond, now several hours later the green LED still is on (solid green). the buttons on the screen is lit but the screen is black. If I press and hold the power button the buttons on the screen starts to blink after a few second, but nothing happends. The same if I try to do a hard reset by pressing vol-down and pwr button. Nothin except the blinking from the buttons on screen. If I try to connect the phone to a computer nothing happends, the computer does not find the phone. If I try to call the phone notheing happends....the phone was turned on when connected to the charger.
Any idéas?
Problem solved, after2,5 hours the LED shut down and I was able to reboot the phone.
If you keep the power button held down for 10 to 15 seconds it will power off, because you can't pull the battery in this device HTC built in a power down feature to the power button

XT890 doesn't start at all.

Hello. This morning I've turned off the alarm, turned on WIFI and went back to sleep. I can't tell for sure, but I think the battery was low. During the next 2 hours I checked the time several times. I don't remember accepting any OTA. Eventually I got up, tried to check the time and the phone was off. I tried to turn it on, no effect. No matter how many times and for how long I pressed and held the power button, the green LED only flashed for a split second and that's all. I plugged in the charger, and the LED stayed lit -but- there was this barely noticeable flickering. Charged it for about 30, 60, 120 minutes, didn't start plugged or unplugged. I went to work, 8 hours later (phone was unplugged) I tried to turn it on again, this time the LED doesn't even flash, but when charging there is no flickering. No combination of buttons works. Windows doesn't find the device, neither does RSD.
I've never done anything 'custom' to the phone. The last change I made was setting the alarm to turn off by shaking (yesterday, never used this option before).
Is it dead?
Try taking SD card out and holding Vol down and then Power for 20 secs, then let go of Power,
Already done that, nothing. No matter how long I charge it now, after unplugging and pressing power button the LED doesn't even flash. Could it be a battery problem (before its death, it would last for a day)? Is there any way of recovering my data without buying a new one?
Try opening and disconnect battery for a bit.
I'll do that as a last resort, on weekend maybe since I don't have the tools with me. Any other clues?
Nobody knows how to help me?
I'm going to make a factory cable. Will this alone allow me to recover the data? Or if I'll be able to flash the phone, can I recover the data afterwards?
Also, I'm not sure if I understand correctly: does the factory cable recharge the battery or not? Is there a way to recharge it when removed from the phone?
Try to use medfield unbrick script. If You have only green led it seems to be bootloader error so this script should bring Your phone to life or Your phone has broken emmc and You can start looking for a new logic board. Good luck.
I've installed the drivers, but Windows and XFSTK don't recognize my device at all. Factory cable also didn't help. I liked my phone very much. :angel:
Did You enter medfield mode using combination with camera button??
By a combination you mean holding the camera button and connecting the phone to a pc? I tried that.
Disassembe Your phone, pull out battery, push power button for a 10 sec, plug in battery, push camera button and connect USB. If it wont help You I don't see any hope for Your phone.
Well, new option to try is a new hope. I'll try that on the weekend. Could you please be more specific:
1. Pull out the battery.
2. Press the power button and wait 10 seconds.
3. Insert the battery: should I be still holding the power button at this moment?
4. Press the camera button.
5. Plug in the usb cable (factory? regular?) - should I be still holding the power and camera buttons?
Battery trick is only to discharge capacitors. Sometimes even phone is dead it can turn on in some strange mode and then You can't boot it to flash. Thats why You need to pull out battery, push power for a few sec to completely discharge motherboard and just release this button. After that You can just plug in battery and continue normal unbrick process - so hold camera button only and connect regular usb cable.
You can also try reset option instead of pulling battery out. To do that do not disassemble Your phone but just plug in regular USB, when phone starts (green led) hold power and vol- until green led goes off and then quickly start holding only camera button.
I have no more ideas.
Ok, I've tried everything. Nothing brought my phone back to life.
Thanks for all your help.

Tab not charging or turning on

I have the SM T815 9.7 32 gb variant. It worked completely fine. Two days back i connected a USB OTG and the tab recognized it, but i couldnt explore it inside the file manager, so i fonally diconnected it. Now the tab was charged to atleast a 20 percent. After removing the usb it showed 5 percent. So i connected the 1.8 amps charger i had. It generally charges it correctly and the charge doesnt fall even in use. I started watching a movie. Even tho the charger was connected the charge kept falling and finally shut down. So i left the tab on charge. It was stuck at 0 percent. At first the screen would show whenever i connected it to the charger, but after mutiple tries it has stopped doing that. I tried the stock charger as well, held down the power button and the volume up key for a minute, connected it and then kept holding the buttons for another 30 seconds. Still doesnt work. If i connect the charger now, the screen doesnt turn on or show any signs of charging.
1) connect the tab to PC;
2) press Home, Vol Down and Power simultaneously up to a screen appears;
3) press Vol Down to cancel and reboot the tablet.
Did this. Now the screen shows the charging icon. The chraging is extremely slow, after about 25 minutes its 2 percent. And the battery side is all warmed up. Should i be worried?

srry for reviving this thread but did your tablet eventually went back to normal?
my galaxy tab s2 does not turn on nor charging.. I connected it to my pc and tried home vol down and power but didn't work
And another revival - did you find any solutions to this? - mine did the exact same things, and none of the suggestions worked
Here we are again.
Another device, same problem.
Had around 40% suddenly went black and since then now sign at all no matter what I connect to it or button combo I use.
Edit:
After nearly one hour of testing different combos I could access download mode and from then on everything worked fine.
