LA-E801P Rev 2.0 (also known by the Compal project names ) is a motherboard used primarily in HP 15-bs series laptops. The schematic details the electrical architecture for boards featuring Intel 6th (Skylake) 7th Generation (Kaby Lake) U-series processors Core System Architecture Processor Support : Integrated Intel Skylake-U or Kaby Lake-U (15W) SoC.
: Utilizes integrated Intel HD Graphics or a discrete AMD Radeon GPU (tracked on dedicated circuit sections like the R17M power rails). la-e801p rev 2.0 schematic
This comprehensive guide breaks down the architecture of the LA-E801P Rev 2.0, details its vital power rails, maps crucial Integrated Circuits (ICs), and offers step-by-step diagnostic workflows for repairing this specific motherboard. 1. Board Specifications & Architecture
When diagnosing a "no power" or "dead" laptop, you must start at the power supply chain. The schematic provides the "road map" to follow the voltage:
The is a solid, workhorse board. It does not push the boundaries of technology, nor does it need to. The schematic reflects a mature design philosophy: keep the power clean, protect the inputs, and route the signals clearly. For integrators looking for a reliable intermediary board for power or signal routing, this revision is a significant improvement over 1.0 and comes recommended. Based on hundreds of repair logs, here are
The LA-E801P Rev 2.0 schematic is likely used in various industries, including:
The high-current processor core voltage rail, managed by a multi-phase PWM controller, active only in the S0 state. 3. The Power-On Sequence
A schematic tells you how components are connected, but a Boardview file (.brd or .cad) tells you where they are physically located. Using both side-by-side is the professional way to navigate the LA-E801P. : Utilizes integrated Intel HD Graphics or a

If you can tell me the (e.g., "power light flashes 3 times," "no sign of life," "turns on but no display"), I can provide a more tailored diagnostic approach using the LA-E801P schematic. For specific component advice, Share public link
Technicians working on the LA-E801P Rev 2.0 frequently report a few common failure points. When analyzing the schematic, make sure to cross-reference these sections first: The Input Protection Circuit
Generated right after passing through the input protection MOSFETs (typically dual N-channel transistors like the PE642DT ). This acts as the main high-voltage highway that feeds all buck converters on the board.
