cannot unlock tablet - Transformer TF300T Q&A, Help & Troubleshooting

Update below
my security unlock screen method is "pattern", i went to setting -> security and uncheck "show the pattern" or "visible pattern" (or something like that. i was curious what is that setting about)
then i press the power button to put it into sleep mode, it turned off the screen, then now when i press the power button again to wake it up and nothing happens.
also last time i tried connecting it to pc it automatically woke up, but now i connect to pc nothing happens, on Computer there's nothing like "Asus transformer pad TF300" either. i don't even know is it turned off or not?
i assumed it was turned off so i tried pressed and hold the power button with no luck.
tried 3 times. battery was 67%. it was working ok before i changed the setting.
also yesterday when i got it i couldn't power it on because there was no power in the battery, i had to plugged it to charge and wait 2 hours then i was able to power it on. so is the battery empty right now? it shows 67%, or is this something related to the setting. i also have bad battery life.
now can't do anything, if i want to return it i can't even do a factory reset to erase my personal data.
UPDATE: i read someone's post hay says he usually have to press and hold the power button for 12 seconds for it to boot, so i tried that and it booted up. yes i said it booted up, which means it turned off when i pressed the power button to lock it. and the battery went down to 63% (from 67% i said above).
so what does this mean? why do i have to press and hold for 12 seconds, (normally 1.5 seconds)? and why did it turn off automatically? battery still drain about 1% every 5 minutes.
so far i have too much problems

Boot Screen Looping

So this is a weird problem I just started having today.
After putting my phone away during practice, I came back to find that it had only 1% battery.
It died en route to my room, and when I first plugged it in to my PC, it turned on and worked normally. After a while it turned off.
Now, when I try to turn it back on, the htc Raphael screen comes up, and it makes a short vibration, then goes to black for about 1 second, and then repeats. It has been doing this nonstop.
However, it only does so when it is plugged in to a power source. When it is not plugged in, it is completely unresponsive.
I have the elite RC2 ROM that I flashed back in November.
Any suggestions?
hard reset to start things off.
Hold down the volume down button, center button and then press the reset button with the stylus until you see a screen that says something like "this operation will delete all your personal data, and reset all settings to manufacturer default. Press VolUp to restore manufacturer default, or press other keys to cancel." then press volume up. Remember you will lose all data, phone numbers and anything else stored on the phone.
i know this problem
I have had several, i solve it taking press the power button long time during the boot.
Of course, the phone must be plugged in to a power source.
Problem solved.
I left it unplugged with the battery out overnight, and then plugged it in to charge, and it did not attempt to startup.
After letting it charge again it worked as normal.
I suppose the battery was so run down for some reason, that even plugged in, it did not get enough power to complete the boot.
It works now. About to flash Elite RC3 and a new radio.

[Q] TF Powers Up, but Touch Screen is not working so I cant get past the lock screen

I did a search but no solutions came up.
Basically, when I touch the screen to move the little lock icon over to unlock it nothing happens.
I powered it off by holding power for 10 seconds and then powered it on again.
No bueno, nothing happened.
Anyone else run into this and was able to solve it?
yes, i had the same problem, you will not like this..
do one step at the time and check if it works, if not continue to the next one
1. cold reboot (hold power button for 30-60 seconds),
you can try step 1 several times
2. turn it off, let it charge for 2-3 hours, turn it on
3. reboot to safe mode (this not really sure how i did it..lol.. i think is, turn off and turn on and quickly hold both volume keys until it boots up, if you did it correctly it will boot and say "safe mode" at the bottom left corner).
4. reset to factory settings, hold volume (-) and power key at the same time, (this will erase everything)
when i had this problem, i actually had to cold rebooted several times and reboot into safe mode after step 4 to have the touchscreen working again..I was about this close () to give up and return it to walmart..
I had the same thing happen to me, and all the rebooting in the world couldn't fix it. I don't know if you're still on stock rom or not, but what I did was reflashed the Prime rom and it worked again.
Nothing helped, even hard wipe.
Returned the TF.
I had this same problem... Unfortunately the only thing that worked was letting the power drain out. That was a huge pain because the Transformer has a killer battery and there are only so many times you can turn the screen on and off to drain it. It took about 4-5 days to fully drain. After that point I had upgraded to 3.1 and it has worked flawlessly since then... definitely a firmware problem not hardware.

Moto G bricked or discharged I don't know

My moto g battery was drained and it wouldn't switch on, i looked for help in XDA and the people said leave it to charge for 3hours and i did. After, 3 hours it showed a battery screen showing it was charging but it was on 0%.1hour later it is still on 0%. Then i pressed the power button and it showed a screen with options like "boot", "factory reset", "hard reset". I first choice boot but nothing happened just went back to the battery screen again and i left it for 10min, and it is still on 0%. Tried the boot option several of times but nothing happens. Later, i choice factory reset and then the screen went blank and now it won't switch on. I done all the procedures of how to force a reboot but none of them works, and i think my phone might be bricked.

Leave it on charger the whole night. If still nothing works get a replacement.

My N5 looks dead, but..

I dont think my Nexus 5 died because the last I saw it still had above 20% to 30 %, but it did just turn off on me and now it will not turn back on. I tried holding down the volume up+volume down+power button for more than 10 seconds and nothing. also tried vol+ + Power and vol- + power. Here's where it start to get werid. I tried to plug it into my PC, but it doesn't recognize it. It's just trying to install the "QHSUSB_BULK" driver (and fail). Also when I place my phone on the charger, nothing happens. I know you cannot take the battery out which really annoys me. After few hours, I tried just turn on with power button and voila, it worked. but i don't know why. it happens randomly. i am root user and tried different roms but still happening. any ideas?
Your battery seems to be near limit of it's age. Try calibrating battery..

Phone won't boot up

I have researched the "related threads" and none are similar to the issue I am having.
The phone turned off midcall and fails to turn on afterwards. I thought it was the battery, but it still fails to turn on after charging over night.
It boots up to show the logo, after a battery pull and turns back off.
If I I press down the power button + down volume+ menu, I get the warning about a custom install of an OS may damage the phone and if i want to continue to press the volume up, or cancel.
The phone only lasts about 5 seconds, after every battery pull, other wise it won't turn on again.
I haven't gotten a blank white screen nor the Android logo.
Thank you.
Update: I believe I confirmed it is a power button issue.
What I used to confirm it was pressing the volume down button and menu without the power button and was able to see the Warning as if I had pressed all three. Also, the phone vibrates as soon as I place in the battery.
Issue now is: Supposedly the cause is due to a stuck power button, but physically the power button is not stuck. It clicks when pressed.
