Windows 10: my windows key, shift key and alt key turn off my pc

i really need help as these are the keys i use the most

Both shift keys

Hello.
I have problem with Lenovo Idea Pad 100 laptop (OS: WIN10). After replacing HDD into SSD I faced a strange problem. Both Shifts of the keyboard doesn‘t work .
I have tried to:

• Check if sticky keys are off. They are off.
• Connect external keyboard via USB port. Shift keys on external keyboard works good.
• Check the keyboard on online tester which indicates pressed buttons. It can‘t indicate press of the shift
• Change several different input languages. The problem is on all of them.
• Reinstall keyboard driver
• Check if connection is OK. It is OK.
• Tried to run computer without screws (I have read in one forum that screws could touch the keyboard from the bottom and it wouldn‘t operate normal)

I believe that keyboard is not damaged because connector damage could cause just exact part of keyboard failure, while it is impossible to do physical damage for both shifts. Any solutions?

 

Both shift keys

He's already tried an external KB and the shift keys work fine.

 

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?
