Firmware update stuck at 100%

im using a dell latitude e7270, yesterday while checking windows updates, I saw a optional firmware update 0.1.36.3 so I decided to do it, but after it went to 100% it was stuck for hours so I removed my charger and let it drain down. After that it went to normal boot up because charge was too low to do the update and then I got notification saying “Restart to set up this device: Firmware 0.1.36.3” the update was still there I can’t cancel it, so I decided to restart and hope this time it won’t be stuck BUT IT GOT STUCK AT 100% AGAIN, I waited overnight this time and still don’t work, the power button is unresponsive so I gotta wait for charge to go down if I wanna check my pc... how do I fix this please
