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.

Hey, my Nexus 4 died a month ago. i have tried many things from the internet, and none of them worked.
When i'm holding the volume down + power button, and inserting the USB cable, the red light is coming up, and it's Solid Red Light, and after about 10-15 second, it disappear. i sent it to one private lab, and they didn't succeed to fix it.
what can i do??
*Note: i'm going to give the device to another Lab - but i still want to hear you people
Simulate a battery pull by holding volume UP and power button simultaneously for one minute, see if that helps get you back running to the point you can at least charge it up and factory reset.
I've had the Red light of dead yesterday because i had critical battery level and didnt charge
I responsed immediately and pressed volume down + power and it entered

And then connected the charger and pressed power button again to select START
It booted and started charging

I know this proccess, but it's not working for me!
I don't know any other fixes. New battery? :/
My wife woke up this morning to an unresponsive phone. It's been on the charger all night.
The screen is off, and the led blinks blue about every five seconds.
power+volume keys has no effect - neither power + vol down nor the standard recovery- or download mode combinations, even holding down for half a minute or more.
The phone hasn't even been flashed - it's still on the original ROM.
Never seen this on any Galaxy device before, I'm completely clueless.
Have you seen this before? Any ideas on how to force it to power down?
Thanks!
force restart is power button and volume down for 10 sec if that's not helping you have a broken phone.
Thanks. As I wrote, force reboot didn't work.
But it seems I was wrong - it did work, but I had to hold the vol down and power buttons pressed for over a minute!
So problem solved, for now.
hi
my little brother made a pattern lock and forgot the pattern, after many tries the phone erased everything
he doesn't know the email he used it on phone or the password
now it boots welcome screen and asks for the old email, i did tried make new but it doesn't works.
so i figured i should just wipe everything with hard reset
from what i read and saw some videos, i should turn off and then connect to power then wait a little, then press power and vol up for 10 seconds then release my finger from the power button.
i tried it many many times but it doesn't works.
any help?
Switch off your phone,then connect the charger to your phone and quickly press and hold volume up and power buttons,after the screen is blinking a bit release power button,but hold volume up until you are in recovery mode.
it doesn't works, it's like the vol up doesn't work when the phone is switched off, but when i power on the phone and finish booting i can vol up.
i can enter download mode (vol down + power) but it doesn't do anything.

Unplug the phone, hold the power button.
It will eventually reboot.
If not hold power and volume down.
There is a known problem after rooting, don't turn the device off and plug it in.
Unlock warning screen stuck "Reboot" fix.
Mine did the same thing the other day and after all the research found out it's Volume UP +Power press for as long as possible, for me it rebooted in 15 seconds. But I'd advice holding it as long as you feel vibrate and reboot. Tried more than few times for mine works Everytime. Don't plug it in while it's off and turn it on to prevent it from getting stuck again.
So I have a rooted oneplus 6t that was doing quite well for a little while now but for some reason today it died when it was hooked up to a charger. When I unplugged it and plugged it back in it did its usual vibration to signify it was connected but then it showed a qualcomm crash error (died too quickly to see it fully but it was small so I at least saw some of what it said) now when I try to let it charge it doesnt vibrate and doesnt even turn on when I left it on charge for a good hour now and when i hold vol up +power,vol down + power,both vol +power,or just power for their respective seconds to get the phone to respond. Tried looking for a answer online but none are similar to what i am having atm. Also my computer wont even see it either while it's like this. I've tried other cords as well to see if it was a cord issue and wasnt it's been sitting on the charger since 10:55 am est. Help?
It usually just takes some persistence. Usually the power + volume up will force it off, and then power it back on does the trick, sometimes it seems like it's all three buttons (which shouldn't do anything?) . I've had a couple times I've been just about to give up when it finally boots back up to fastboot.
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Make sure you hold the buttons much long than you think you should have too.
