The phone is switched off due to a fall impact which caused slight movement to the battery interrupting the power. Is there any way to boot without those important keys? It's stuck on the battery charging screen when I plug in the cable and I can't think of any other way to bypass that to access recovery or download mode because if I do, I can boot the phone from either of those two using adb or fastboot commands. I can't do anything on the battery charging screen. Is there a reset pinhole or something in this phone? Is this a dead end?
Should be able to short the power switch pins, I replaced the switch in my nexus 5 ages ago and couldn't tell you which pins did what, but it's 100% possible with a small length of wire/paperclip.
Run fastboot oem off-mode-charge 0 on the bootloader the next time you can and you'll be able to turn on your nexus just by plugging it in into a computer or charger. Quite useful when your power button doesn't work.
And yes, shorting the power button is the only way you're going to turn it on, careful though.
To access the bootloader without volume down you can use adb reboot bootloader

Pulled my bone-stock (with current OTA updates) Nexus 5 out of my pocket and the screen was already on. It was asking for an encryption password to decrypt the data on the phone. I figured it may have turned on in my pocket and the pocket movement caused too many pattern unlock attempts. I turned it off and went about my business for a bit. Now the phone won't turn on.
It does not respond to being plugged into a known working usb cable and usb charger.
It does not respond to being placed on a known Qi wireless charger (the charger does indicate a connection).
My computer recognizes it as a QHSUSB_BULK device, but cannot find/install drivers for it.
Tried every power combination of vol-/power, vol+/power, vol+-/power.
Any suggestions?
Sounds like you busted your bootloader. I guess even the secondary won't come up?(Both volume keys and power button)
secondary bootloader fix attempt
Unfortunately my phone did not respond to those combinations of power/vol buttons.
Hello.
My power button is broken. The only way I know to turn the phone on is removing the battery and connecting it quickly. I could get into the stock recovery pressing vol + and connecting to the charger but I need the power button to select any option, I installed TWRP recovery but I cannot use it, the button combination is different to get into (vol + & power button).
Is there any other way to turn on or use recovery when the phone is off?
Thanks
Fastbooting it from the computer is a solution..
Fastboot is disabled in android marshmallow. Now, how can we boot the phone ?
One last resort option is to send it to Alcatel. I had issues with my power button failing and they resolved it. (FTR I was still under warranty)
I had this problem. Eventually found a video for it on YouTube. I couldn't return my phone to Alcatel as I had dropped it in the toilet ? and then taken it apart to dry it out.
If its still under warranty I would return it to Alcatel. If not then the way to turn it on is a bit of a pain at first but quite easy when you've done it a few times. You do have to take the back off your phone.
If you are happy there is a reasonable amount of charge already in it then plug it in to a charger whilst holding the volume up button (or down button I forget which!) This should start the phone in the recovery mode.
Then unplug the phone.
Then very quickly disconnect and reconnect the battery.
Phone will turn on.
Put phone back together.
Keep battery charged!
Some kind person made a video:

D2206. Got into a bootloop (the phone only shows the Sony and Xperia logo but ain't starting the system and just restarting forever doing it again and again). Can't get into Fastboot mode because volume buttons and power button isn't reacting at all. The only solution to force it to show some traces of life is plug him to PC or to a charging device but nothing happens except the charging lightning animation appears. And after connecting to PC, it seems like Flashtool recognize him, but nothing can be done because of the periodic 5-7 second interval disconnects.
Any solutions or tips?
You need to power off before connecting. Here's how.
I don't know if you figured this out or still need the help now, but I'm answering because it's the one thing here that I do know the answer to.
From your description, it sounds like you are trying to connect your phone to PC while the phone is still in boot loop. This will not work. You need to power it off first. Since your power and volume buttons won't respond during boot loop, you will need to use the hardware override that is provided.
Under the back panel of your phone, between the SIM2 and microSD slots, you will see a small punch-hole about 2 mm in diameter and labelled "OFF." Use a pen or precision screwdriver to gently press the off switch located inside this punch-hole for about 1 sec. Phone should switch off.
Wait about 15 sec before connecting to PC in Flash (Vol Up pressed down) or Fastboot (Vol Down pressed down) mode until the LED flashes the respective colour and then you can follow whatever instructions you are following.

(I'm noob)
Option 1: Unplug battery from circuit board, and unplug usb plug. At this stage, the phone is off. With battery unplugged, press VolumeDown button and plug in usb cable (the usb cable must be powered either from charger or computer). The phone should start in bootloader mode. If you want to enter recovery, you must plug back in the battery connector to the circuit board, other wise the phone will just turn off. Then proceed with ADB/Fastboot as you suggested. (Tested this method right now to make sure it worked before posting)
Option 2: You may have a chance a starting the phone by short circuiting the pins to which the PWR and/or VolumeDown buttons are soldered to on circuit board.
I tested this method because my PWR button was broken and was acting like it was always pressed which forced a reboot each time. I unsoldered it and dismantled the button, clean inside it by scrapping off dirt and recreating the bend or dome shape of the button mechanism. I then finished by re-enclosing the button and then soldered it back to the circuit board. It worked fine, until next morning upon wakeup I decided to resolder the button because it wasn't perfectly parallel to the side of the board. By re-soldering, I destroyed the solder pad and was never able to solder it again. The phone is not usable as a daily anymore, only usefull for surveillance cam or server...
Edit: found this thread that may be usefull for you.

I have had my OPO for about 4 years and am currently running Lineage 18.1 with no issues. However the Power button on the phone stopped working and will not do anything. I inadvertently put it in Fastboot and cannot get out of Fastboot and reboot to normal. I have tried adb to see if I could do a reboot there but it is not detecting any devices. Before this incident the phone was unlocked, in developer mode with usb debugging set. Is there some other sequence to try. I have tried vol down and plug in usb, and vol up and plug in usb, and held vol up and down and plug in usb but none have worked. Any suggestions please.
Update: I just got Fastboot on the PC to reboot the phone. Yea. The Power button is shot. It has been in a case for years and I hardly ever use the Power button anymore. Don't know why it has failed, no abuse, maybe lack of use. Thanks anyway.
If I take the button out, does anyone know if the inner switch could be pressed with something to turn it on and off. I assume there would be somethin like that although I have not been inside one of these before. If I ever lose power on the phone I will not be able to turn it back on without the power button/switch.
