F6 key is out of control - No Standby
My F6 key is out of control. Without being pressed manually, it functions. F6 on my Mac is keyboard illu up. This comes randomly, every minute, every hour. But this is not the problem overall - due to that problem I cannot go into standby, cause when I close the Mac it goes into standby then wakes up cause "the key is pressed" and so on and on and on. I have to turn him off completely what for a Mac of course is a state of no-go.
I have removed the key, removed the nibble, nothing helps.
Can anyone help me and my 5 year old baby? New keyboard top case is 200 $. Cannot invest that.
