Not turning on - Nexus 7 Q&A, Help & Troubleshooting

Guys, I can't turn on the device since 2 weeks ago. IIRC, the battery was empty and hence the device turn off. I charged it overnight but couldn't bring it up. I have tried the below(which is not working):
-Hold power button for 30 seconds(or more)
-Hold power button + volume down with charger plugged or unplugged
- Hold power + volume up+down butoon
- Left 2 days of charging
- There were blinking in LED for 5 times in random day when i plug in charger but still couldn't boot or boot to bootloader
- Remove and put back the battery
- Tried different charger (ori and non ori)
- Tried USB charger through PC and can hear the "usb plugged in" sound from my laptop but can't see the storage from My Computer. Tried holding down power button and there was a sound that alerts usb plugged in/out
ANy idea what's wrong?

Won't charge

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.

Nexus 4 Red light Problem

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

[Q] Nexus 4 Does not turn it on, Red Notification light blinks only

This morning my nexus 4 (Android 5.0.1) having some issues about crash of google applications. I decided to do factory reset so i went to settings and apply factory reset, it was showing power turn off then after it has not been started again. I tried to plug charger and everything but nothing is worked out.
Now, when i plug my nexus to wall USB charger or laptop USB charger then i can not able to see any charging icon. I tried to hold down power + volume down keys but nothing happen. But when i hold power+ volume down keys and plug it to any charger it shows red notification light which blinks for 10 seconds when i leave power+ volume down keys red notification light went off.

Problem to power on Leeco Pro Elite after battery is fully discharged

Hello to all,
can someone help please.
my battery discharge completely and my phone turned off, after that I can't to power on. When I use power button I only hear vibe and nothing happens, also same problem is when use combination with volume buttons. When charging phone via adapter and USB cabal via laptop nothing happens - no led charging red light or picture on the screen that battery charging.
I managed with combination power + volume button to go in bootloader mode (on device manager on PC it shows "Android boot loader interface")) but on the the screen of phone nothing.
Also sometimes when use combination of buttons I managed to power up red led for signal that battery charging sometimes but when I plug off cable it still flash, it is on.

[Help] one plus 6t not vibrating or turning on after being plugged up

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.
