Schematic — La-e801p Rev 2.0

: Often fails at the first input MOSFET. If 19V enters but doesn't pass the first stage, check the gate voltage and surrounding resistors.

Often bundled with the schematic on repair forums like Indiafix or Facebook repair groups .

The features outlined above provide a general idea of what might be included in a laptop based on the LA-E801P Rev 2.0 schematic. Actual features can vary based on the specific laptop model, manufacturer customizations, and market region. This list serves as a reference for understanding the capabilities and design considerations of laptops built around this platform.

The schematic will show the inductor (PL..., e.g., PL401) for these rails. A common diagnostic trick is to desolder or measure the resistance to ground at these inductors. If the resistance is very close to Ω (e.g., 0.2 Ω), a capacitor further down the line is shorted. 3. Power Good (PWR_GD) and the SIO Chip la-e801p rev 2.0 schematic

models. This revision typically features Intel's 6th or 7th generation "U" series processors (Skylake-U or Kaby Lake-U) paired with DDR4 memory. Key Specifications & Architecture Processor Support : Supports Intel Skylake-U Kaby Lake-U 15W processors with integrated PCH. : Dual-channel DDR4 SODIMM slots supporting up to 2133MHz at 1.2V. Graphics Options : Integrated Intel graphics. Discrete (DIS) : Supports dedicated GPUs like the AMD Radeon R17M-M1-30 R17M-M2-50 with up to 4GB of GDDR3 memory. I/O Connectivity

The schematic outlines several critical power states and rail addresses for troubleshooting:

: Integrated Intel HD graphics, or discrete AMD Radeon (e.g., R17M-M1-30 or R17M-M2-50) via PCIe 3.0. : Often fails at the first input MOSFET

No. While many manufacturers use Compal-made boards, each brand's schematic is proprietary. A Dell LA-D801P board is completely different from an HP LA-E801P board. Using the wrong schematic will lead you to incorrect diagnostic conclusions. Always ensure the schematic matches the specific motherboard model and revision for the laptop you are repairing.

LA-E801P Rev 2.0 (also known by the Compal project names ) is a motherboard schematic used primarily in HP 15-BS series laptops and some Dell Latitude 3580

Troubleshooting a dead or shorted LA-E801P board requires mapping out the fundamental power rails. These voltages must be generated in a specific sequence for the laptop to post. Power Rail Nominal Voltage Purpose / Target Area Primary input from the DC jack before protection MOSFETs. +PWR_SRC Main system power bus distributed to all buck controllers. +3VALW

: Technicians often report low resistance on the source side of the first MOSFET (PQB1) or the PQA1 chip, even when the MOSFET itself tests fine.

LA-E801P Rev 2.0 is a motherboard/mainboard reference/schematic designation used for certain laptop or compact-system PC models (often found in service manuals and repair schematics). The schematic documents the board’s electrical design: power rails, CPU/SoC interfaces, memory interfaces, charging and battery circuits, audio, USB/PCIe lanes, power management ICs (PMICs), voltage regulators, clocking, and major connectors.
