Weird Power Button functionality issue (Aspire 5 A517 51 59v5)

My Dad turned on the laptop as always and left it on. After 10 minutes it probably went into sleep mode. An hour later I came and my dad asked me to wake the Laptop. After pressing the Power Key, nothing happened. Pressing ANY other key besides the Power key turns the Laptop on for about 5 seconds until it dies. Altough the power button is able to force shut down the laptop by pressing it 5 seconds long, if the laptop makes it past 5 seconds.

The weird thing is: When bypassing the powerbutton by shortening the connectors pins, disconnecting the keyboard and connecting a different keyboard, the Laptop works just fine. When reconnecting the keyboard to the Laptop while it is running windows/booting, you can even use the Laptop as intended. Its like the problem dissapeared. The Power buttons functionality isnt broken or anything. Putting the laptop in sleep from there is also no issue, but: When the old keyboard is connected, the power LED very quickly flashes red and the laptop completetly dies.

We have dissasembled the Laptop and tried many different methods:
>Remove Memory and SSD (upgraded, worked fine for months)
>Remove Battery
>Use SWG2 Battery switch
>Disconnect and clean keyboards ribbon cable
>Set Bios settings to default
>Tested contacts for shorts with multimeter
(I wont update BIOS, it could brick the laptop completely)

Its like the laptop is trapped in a sleep mode state when its shutdown.
I would appreciate any support. If you have any questions, lmk. If I find a solution, I will post it here!

    This is a 7-year-old model laptop that may have a bad power button contact and the battery probably needs replacement if still the original one. Forcing the system to shutdown with the power button corrupts some boot files that are not always replaced in Windows. I recommend bringing the laptop to Acer Services to check the booting issue, reprogram the EEPROM and reset the system to factory defaults for a small service fee.

    The Laptop does not have booting issues, rather starting ones. About the bad battery: The battery was unplugged and the Laptop was plugged in, so energy could not have been an issue. Both plugged in and battery powered had the same issues. I will consider bringing it into Acer Services or a third party, although I want to try and solve the issue, share my solution and maybe make someone's day. Sharing is caring. Although I thank you for taking your time to write that comment!
