I posted a question about my laptop's LCD blacking out from time to time (only fixed by reboots). So now...
1) I ruled out a BIOS problem
2) I ruled out any other software problems
3) The LCD does not black out when I touch the screen or move it open and shut
4) It blacks out when I touch the AC power supply cable where it connects to the laptop
SO IS IT A DIRTY CONNECTION I COULD CLEAN WITH ELECTRONIC CLEANER, IS IT A BAD AC POWER SUPPLY CABLE, OR IS IT A LOOSE SOLDER CONNECTION INSIDE THE LAPTOP NEAR THE AC OUTLET?
or something else or combo of above?...
