This Video About How to Fix PWM Glitch With an Oscilloscope
Problem -: Sometimes On and Off
How I Fix -: First I Checked with Multimeter 19v, 3.3v 5v STB Showing OK
When I press the PWR Button Laptop does Not Power On Properly
So I decide to check STB Supply With an Oscilloscope.
Then I Found a Glitch in the 5V Standby [ALW] PWM Section of the Motherboard.
I replace that Capacitor with a 330uf Tantlom Cap.
Then Issue Fixed :)
