If the laptop charging brick's LED blinks or turns off immediately when plugged into the laptop, there is a short circuit on the main power rail ( VIN / +19V ).

An open-source, cross-platform (Windows, macOS, Linux) viewer that handles .brd files beautifully. string

Use the boardview to locate the Step-Down PWM controller IC (often manufactured by TI or Maxim) responsible for generating the standby +3VALW and +5VALW power rails. Test the surrounding capacitors and inductors for shorts to ground.

The most common motherboard platforms for this model include: (e.g., Rocky_48_4SI01.011)

Liquid spills often corrode the copper traces hidden beneath the motherboard's green or black solder mask, resulting in open circuits.

Use your multimeter to check if 19V passes through both MOSFETs.
