Bdl51 Lad711p Rev 30 Schematic Work !!hot!! -
If you can provide the specific issue you are facing (e.g., "no power," "stuck on screen"), I can offer more tailored troubleshooting steps, such as specific voltage points to test or which components are most likely to have failed.
HP 15-ba009dx, HP 255 G5, HP 15-af series. Processor: Integrated AMD (UMA). 2. Key Schematic Areas and Component Identification
A shorted USB port can pull down the +5V rail.
This article is for educational purposes. Always refer to manufacturer service data where available. Voltages and component locations may vary between production batches of REV 30. bdl51 lad711p rev 30 schematic work
: In liquid damage scenarios, common components to check or replace on this board include the (charging IC), (Multi-IO/EC), and MOSFETs like the Power Rail Verification
Contains the functional diagram and component values.
A reading close to 0 ohms indicates a critical main rail short. Do not plug in the charger. If you can provide the specific issue you are facing (e
Before consulting the schematic, visually identify these common elements on the REV 30 board:
Subsequent rails initialize in order: Memory power ( +1.35V or +1.2V depending on DDR3L/DDR4 layout configuration) followed by the SoC controller power ( +0.9V / +1.X_SoC ).

Power enters through the DC jack and must clear the protection logic before traveling to the rest of the board.
Press the power button and observe the multimeter. The voltage must pull down cleanly to 0V and spring back up to 3.3V when released.
