My YB refuses to boot. Symptoms:
- when plugged into charger, white indicator light pulses slowly (about 3 sec on / 1 sec off); doesn't matter if lid is open or closed
- If I hold the power button down for 11-12 seconds, I get a short "haptic feedback" buzz, but no other response.
- If I then press the power button briefly, I immediately get a short buzz but no other response.
- No combination of button presses does anything different.
All of the above is with the charging cable connected. If I unplug the cable, the white indicator light continues pulsing until I press the power key for 12 seconds, then it goes out (no haptic buzz, though).
All of this happens with or without an SD card installed.
Windows doesn't see it as storage, and adb doesn't see it at all.
Any suggestions (aside from "it's dead")?
It could be an issue with the screen. Most likely a problem with the power of the screen. Your YB turns on, but displays nothing. Is its guaranty still valid?

So I started writing this post as I though my phone was bricked. Anyway the story:
So, I'm calibrating my battery. Battery was totally flat so I plugged into AC. Was working on assignments and watching TV for about 40mins answer phone call talk for 10mins (still plugged in) go watch TV for about 30mins come back, all the button lights are on. WEIRD. Red led Flashing. WEIRD. Press power to unlock. Nothing. Press power again nothing. Hold Power nothing. Power + Vol = Nothing. Oh sh!t. take out power, lights go off. Try to power on as before = nothing. Oh crap what now? Take out battery, sim and sd. Replace battery after 15 secs. Power on nothing. Plug in lights come on again. Power = nothing. Eventually after stressing out for a little while and repeatedly unplugging and plugging in. It booted into charging mode. and now weirdly all my GO widgets (and only the GO widgets, not facebook, etc) are gone WTF is going on.
this is so weird that no one has experience....
I just had a similar experience. I was charging my Ideos x5 on front usb connector of an old computer. I guess it didn't had enough voltage because the phone suddenly went dead. And than ... led blinking red and softbuttons started glowing on and off. When plugged in normal charger for a couple of minutes, the led changed colour to normal and there was a picture of battery on the screen.
Hello all,
My mother got an a500 about seven months ago and the other day she put it to charge and the next day it wouldn't turn on at all, just a black screen. When the charger is plugged in, the power button glows white. Take it off charge and the light goes out and that's all it will do.
I have tried searching through multiple forums and I have tried all the solutions I have found. I tried pressing the reset button near the usb plug, I tried a hard reset by holding the power and volume + buttons multiple ways, i.e. I held them both for thirty seconds, held the vol button and pressed power for three seconds and about every other iteration I could find. Nothing happened not even a vibration like from what I've read it is supposed to do. I downloaded the update.acer.zip file and put it on an sd card and tried flashing it by holding the power and vol - buttons, still nothing.
The tab has not been moded in any way, however, God only knows what apps my mother way have downloaded to it...
I am at my wits end and I don't know if I'm doing something wrong or what. Any help would be greatly appreciated. I am a noob so it wouldn't surprise me if I am not doing the flashing right or if I have the wrong files, all the links I found on the forums were non functional and I had to download it from filecorp.com.
Thanks in advance!

The white light when plugged to the charger just indicates it's fully charged.
Test 1. Press and hold the PWR button for 7 seconds, release, wait a couple seconds to see if it responds, then press and hold for another 7 seconds. See if it responds.This is to check if the tab is in Sleep of Death (SOD)
Test 2. Using a paper clip, press and hold the pinhole reset (near USB) and then press and hold PWR. After 4 seconds release PWR, 1 second later release pinhole. See if is vibrates and goes into APX mode, (tab should vibrate once with a black screen and white PWR button) if it does, press and hold PWR only for a few seconds. Wait a couple seconds, then PWR on tab by holding PWR about 6 or 7 seconds.
Test 2 is just to see if the tab responds to anything,
If you can't get any response from the above, then it's best to turn it in for repair.

@Moscow Desire: he pressed the reset button already so it is probably not SoD. Unless SoD makes reset button unresponsive too.
My tab does not vibrate when entering APX mode at all. Only the white power button LED turns on and the screen stays off.
@Core645: try this at first
- disconnect charger so the LED turns off
- hold power button for about 5 seconds
If the power button LED turns white and nothing else is happening then your tab is stuck in APX mode. You can confirm this by connecting micro USB cable from your PC. If you have windows it'll ask for drivers for Nvidia Download Mode or something like that.
Then check what Moscow Desire suggests with the reset button. I only ask you do my check at first because by holding reset you would achieve the same result and you wouldn't know if it is stuck in APX or you just forced it to APX by holding reset button.
I did a search and nothing was answered other than to try the whole "power off device via bootloader and BAM problem solved"...which doesn't work for me. I also have some issues not discussed. It seemed easier to just start a new thread.
So my wife let my N7 completely die. So she goes to charge it and it won't charge. She tries another cable and those don't work either. So here is what happens, and what I've tried so far. Also, I am rooted running CM10.1 I believe.
1- push the power button:
Up in the top left corner i get the text "show low low battery icon!" device turns off after about 3 seconds.
2- plug in charger:
When I do this, the little battery charging this comes on and the battery fills 3 times then the screen goes off (about 10 seconds)
3- hold power button for 30 seconds
if the charger is plugged in-> it brings up the battery w/lighting bolt, then says Google, then shows Cyanogen mod boot animation, then loads up my home screen, then instantly powers off because of no battery (0%). then starts all over and will repeat indefinitely (given that i continue to hold the power button down.)
charger not plugged in-> shows battery icon, says Google, then CM10 boot animation, then loads home-screen, then powers off, repeat indefinitely
4-if i take out charger after putting charger in:
it will still show the battery charging sequence for the ~10 seconds even though no charger is in
5- with charger in, pressing power and volume down:
takes me to boot-loader with the android laying on its back with its torso open. it says information in bottom left corner. it says start up in the top right by the power button, then has an up/down arrow by corresponding volume keys. Pressing volume keys does nothing. pressing power does nothing. I can hold the power button and it will restart, says Google, play CM boot animation, load home screen then power off.
6-without charger, pressing power and volume down:
see object 5
7- press power while charger connected.
Tablet loads with the whole Google->boot animation-> home-screen. while on the home screen, device starts powering off (0%) battery. while this is happening I can press the power button again to bring up the power menu. I can power off or restart:
a) power off: turns off device. nothing changes
b) restart-> boot-loader: restarts into boot-loader. see item 5
c) restart->recovery: tablet restarts, but then just goes to a black screen and then turns off. (sometimes it will also do a "normal" restart and load back to home-screen and what not)
d) restart->restart: restarts tablet normally back to where it will turn off immediately.
It does all of these things consistently. I am not sure what exactly I should do to try and fix this. any help would be greatly appreciated.
Thanks.
Hi guys. So this is my situation; my phone is currently turned off.
If I hold the power button, the Samsung Galaxy S4 logo appears in with the black background, then disappears and the phone turns off after 1~2 seconds.
If I hold the power, volume down button then I get the custom OS screen. If I then choose to restart from this screen, the phone restarts and the Galaxy Logo shows for around 6-8 seconds then disappears again.
If I go to the custom OS screen again, then press restart, I can then hold the volume up button and the lock button and the blue message saying 'Recovery Booting..' along with the same black Galaxy logo then the screen disappears after 1-2 seconds seemingly turning off, then it vibrates once after a couple more seconds then does nothing again
I can not get the recovery booting screen from simply holding Volume up and the power button, I need to do it after restarting through the custom OS screen.
My phone is also suddenly not recognising the charger being plugged in. There is no observed difference between attempts to turn it on with/without the charger plugged in.
The last time the phone was properly turned on, it switched itself off at around 4-6% battery left and from then on I have this result.
So, can you guys help?
Your power button is probably faulty. Try to wiggle it lose or replace it.
Please help I was using my phone when the screen suddenly goes off but the phone is on, the screen is blinking (lights up and off) continuously but it stays blank. I can open and close the screen by clicking the power button as you would normally do if you're checking the time on your phone. I tried pressing the power button for more than 15 seconds; tried the volume down + power button for more than 15 seconds, and tried the volume up + power button combinations. I tried it while it was connected to the charger and I also tried it without connecting to the charger. All it does is restart/boot my phone I know because it vibrates, but no logo, no display of the battery charging, but the notification light turns red when connected meaning it is charging. I can connect it to the computer also and it displays my device's model. But all in all the screen just stays blank and just keeps blinking (like lighting up and down). The phone wasn't dropped and it did not get wet by any liquid substance, when it happened the battery is up to 87% and I left the screen off for 4 hours before using it then it happened. I am out of solutions as I can't also reset it as there is no display even the logo and battery charging display are gone. But I know it is alive because I can turn it on and off and connect to the charger and pc. If anyone knows or can diagnose the root of the problem it can lessen my worries and maybe just resort to bringing this to a cellphone repair shop. Thank you. TT____TT
