Replying for others that may find this later. This is the correct solution if anyone ever messes up the BIOS and it won’t boot. Basically drain the battery by charging a phone or something with it via the USB port. ALL. THE. WAY. and then give it a few presses of the power button to be sure it’s completely drained, then plug it in and wait 10-15 mins while it gets some initial charge. Then hold down the power button for 8-10 seconds and it should boot up like nothing ever happened.
Basically resets the CMOS to defaults (BIOS defaults).
