          3.3v/5v present and power button led light glow for some seconds and turn off, check your SIO requirements.

          But before then check if standby IC pgood is available. Check if 3.3v/5v coil frequency is fine,output and input before moving to sio, check if rsmrst# is available (active low or active high) when power button is press.

            by DenK
            Dear all, I am trying to troubleshoot an Acer Aspire 5 A514-55 that won't power on. I'll describe the symptoms and my findings so far, and I would like to seek guidance and suggestions on possible suspects in terms of cause/component failure. My initial thoughts are battery charger IC and/or ideal diode/MOSFET (that switches between incoming DC and battery power), but I could be totally wrong on this.
            1) Laptop was working fine on battery, then user realised battery was running low. Plugged in AC adapter but noticed it was not charging (LED on AC adapter plug did not light). Eventually shut down
