What's the cause of this problem ? Can anyone give the relevant solution please ? If i left the function key my laptop get turned off does this problem have anything to do with operating system? I can't do my work properly because of this problem do I have to go to third party shops to solve this problem or anything else like that ?

PC Key Power Switch

Hey! I'm how do I make a PC key power switch? This is the keylock I'm going to use: http://www.biltema.com/no/Bil---MC/Bil-tilbehor/Bilelektrisk/Strombryter/Tenningslas-43076/
It has:

• Universal threepositioning ignitionlock. Has following functions: off, ignition and start (rebounding/momentary).
• Delivers with 2 keys.
• Screw-connection.
• Mountinghole: 25 mm.

So I want it to be exactly like this: You turn it on like a normal car. You twist the key to a certain point, and it springs back. Like in the video
The normal power button should not be involved. You just turn the key to start and stop. And I was wondering, in this situation the way I want this, it is possible to take the key out without turning the power off and do you turn it off by twisting it in the same direction again?
