Lae801p Rev 20 Schematic Better Online

Technicians frequently use the LA-E801P Rev 2.0 schematic to resolve several recurring motherboard faults:

Managed by a complex sequence of VRM controllers, including dedicated regulators for +3VLP, +5VALW, and +3VALW. Common Issues & Troubleshooting Steps

The is a critical resource for technicians repairing HP 15-BS series laptops. While the Rev 1.0 version is more widely available online, finding the specific Rev 2.0 diagram is essential for troubleshooting newer iterations of this motherboard that may feature updated power rails or component layouts.

For boards with failing discrete AMD GPUs, the Rev 2.0 schematic provides the necessary jumper and resistor configurations to disable the dedicated chip and force the system to use integrated Intel graphics. Why Revision 2.0 Matters

Ensure the 3.3V and 5V standby voltages are present. A common failure point on this board is the source side of the power-in MOSFETs showing unusually low resistance (e.g., 7Ω), which often indicates a short circuit in the downstream rail. No Display Issues: Technicians frequently use the LA-E801P Rev 2

Repairing a Rev 2.0 board using a Rev 1.0 schematic can be misleading. Manufacturers often tweak the or swap out proprietary PWM controllers between revisions. The Rev 2.0 diagram ensures you are measuring the correct test points and referencing the exact part numbers for surface-mount components.

Problems in the Real-Time Clock (RTC) circuit can prevent the board from completing its power-on sequence. Graphic Conversion (UMA Enable): No Display Issues: Repairing a Rev 2

(also known by its CSL50/CSL52 design codes) typically features the following hardware:

Options for UMA (Integrated) or discrete GPU (AMD R17M-M1/M2) with dedicated DDR3L VRAM.

Verify if 19V is passing through the first and second MOSFETs (e.g., PQA1).
