Boot without power button? - P8lite Q&A, Help & Troubleshooting

Hi guys
I have a problem - my vol+/- buttons are working just fine but I have problems with power button. It isn't working.
I tried to figure out a way to turn my phone on when battery dies and I found a way - I just need to wait for alarm clock The problem is that I have to wait till my morning alarm rings. Is it any way to turn phone on? ADB and fastboot don't work. Phone can be easily charged
Thanks for help

fastboot reboot
And done

weird power button operation-g3 wiz

Hi guys, I hope I can type this coherently.
I have a g3 wizard that I have flashed many times over the last year or so. Lately the power button has stopped working. I can get the phone to turn on by plugging it in, and then holding in the camera/voice buttons and THEN hitting the power button. It goes into the rainbow screen, and I just soft reset via the hole on the side. At that point it is on and running fine, but the power button does nothing.
The power button does nothing at all unless I plug the phone in, and then only if I go to bootloader. It seems to work just fine to do that-which is what is stumping me. I thought the button was just broken. The charge/battery lights do come on.
For now I have it set to never turn off, so I try to make sure it doesn't run too low. The battery life seems ok. Any tips? I want to be able to put the phone to sleep again...
thanks

I think you can get to Download mode by holding both volume keys simultaneously, then plugging a usb cable. Can't verify that right now but maybe then you can use adb or fastboot to reboot in normal mode (adb reboot or fastboot reboot)

[Q] Power Button Problem

Hello. I just notice when I update the firmware to NF4, the power button of my note 3 has a problem.
Here is the scenario.
I turned off the phone, remove the battery then insert it back. Trying to turn on or boot my phone using the power button but no matter how I try to press still no luck. When I charge the phone, of course the battery icon is in display. I press the power button then that's the time it boots.
Anyone been experience like this? What is the solution? I already tried to reformat the phone but still the problem is there.
Thank you for the help. Thanks.

If it was a power button problem it shouldnt be rebooting again and again? My phone works for 2 seconds and then its dead

Your phone should not turn on by itself after inserting the battery.
So it's definitely something related to the power button.

Black Screen Of Death!!! HELP!!!!

i have my phone for almost 7 months already. my phone went black and it wouldnt charge nor turn on. it wouldnt also turn on the LED blue light. been doing all the tips i can do. dont know if my phone is dead nor anything. cant feel no vibrate nor anything at all. i think my phone is dead dead. can you guys please help me. i got important phone calls and everything that i need to get it done. let me know asap. thanks!!!
If it doesn't charge, won't turn on, and doesn't vibrate, sounds like it's dead! Get in touch with Samsung about a replacement
Try a wireless charger
if you can charge it, can you get into download or recovery mode using button combinations?
Have you really tried *all* the possible 'tricks'? I remember the exact situation you just described happened to me a couple months ago. I left my phone charging overnight and when I woke the phone did not respond at all to any button smashing or resetting etc.. so what I did was, hold down the power button, Bixby button (not sure if that was necessary at all), and the volume *down* button all the same time (like you would press ctrl + alt + delete on a keyboard). I held it for 10+ seconds and at last my phone entered the recovery mode set-up which prompted me to press the volume down button once again to restart the phone. If you haven't tried this, give it a go!
