Short Circuit on the Main 19.5V Rail ( +19.5V_VIN ) ipkbl-sr 35w schematic
Because the board is rated for 35W, the schematic will show a simplified power phase design.

The screen flickered one last time before the board finally glowed cherry red and melted into a puddle of silicon and solder. I was a tool, the final line read. Now, I am a memory.
Includes a standard protection circuit with dual MOSFETs to prevent reverse polarity and overvoltage. 🛠️ Repairability & Diagnostics
The entry point of the power circuit features two N-channel isolation MOSFETs acting as a protection gate. If the board has no standby lights and draws zero current, look at the schematic's charger IC section. Measure the gate voltage of these input MOSFETs; a failure in the charging IC or a shorted ceramic capacitor downstream will pull the gate voltage down, locking out the 19V supply.
