I have a IBM t-22 laptop that when you press down on the top of the lcd sreen it will send the laptop in to standby mode. It works almost like a button , you can simply turn it on and off of standby by pressing down on the laptop screen. Wierd thing is i have replaced every part in this laptop, from the lcd to motherboard. The only thing i have not replaced is the battery or the cpu and of course the plastic case. any ideas or crazy theories are welcome. Let me also say that b4 i replaced all the parts you could make it go in to stand by by moving the lcd back and forth some. Now it takes direct pressure on the top of the lsd but it still does it.
