A faulty keyboard on a laptop computer is a death sentence for the computer, if the keyboard is one of those kinds where the power button is a button on the keyboard and not a dedicated button on its own PCB.
Because such keyboards are usually glued to the laptop housing and cannot be replaced.

And good luck trying to find which pins to short on the motherboard's keyboard connector. That is, if it's even possible to short pins that are so fine and densely packed together on the connector.
Bring back dedicated power buttons and boards!
