The KB9022Q is frequently used on this board. It manages the power-on signal (RSMRST#) and keyboard/touchpad interface.
Switched on only after the Super I/O validates the initial power button trigger sequence.
To help you resolve your specific hardware issue, could you share what the board is exhibiting (e.g., completely dead , spinning fan but no display , not charging the battery )? I can provide the exact component designations and voltage values to test next. Share public link lad711p rev 10 schematic top
The center of the board is occupied by the AMD APU, which combines the CPU and GPU. This is usually the BGA component, requiring precise heat management. 2.2. Power Management IC (PMIC)

(often referred to as BDL51) is a widely used motherboard, specifically designed for HP Pavilion 15-BA and 15-AF series laptops, which primarily feature AMD APUs. For laptop repair technicians, a clear LA-D711P REV 10 schematic top
boards, a weak soldered RAM connection or a failed MOSFET in this area causes this issue. 5. Finding the LA-D711P Rev 10 Schematic and Boardview To help you resolve your specific hardware issue,
Positioned directly adjacent to the SoC to keep trace propagation delays minimal. It supports low-voltage DDR3 modules. 2. Power Management & Charge Control (The Charging Section)
Measure the voltage at the source and drain terminals of the input isolation MOSFETs. If 19V halts at the first transistor, verify the gate bias voltage.
