La-e801p - Rev 2.0 Schematic
Before diving into the schematic, you must understand the board's layout. The LA-E801P is an Intel-based board, typically paired with:
The "Rev 2.0" designation is critical. Dell and Compal (the OEM manufacturer) released multiple revisions of this board. A schematic for Rev 1.0 may have different resistor values, missing test points, or altered power rails compared to Rev 2.0. Always ensure your schematic matches the revision printed directly on the PCB.
If you cannot find the file after 30 minutes of searching, reply with "boardview needed" and I can describe the exact resistor/transistor locations for common failure points without the diagram.
I'm looking for a specific type of information!
It seems you're looking for the schematic for the LA-E801P Rev 2.0 motherboard.
The LA-E801P Rev 2.0 is a motherboard model, and schematics for specific motherboards are usually only available through a few channels:

LA-E801P Rev 2.0 schematic is a critical document for repairing HP 15-BS series laptops, which use the Compal CSL50/CSL52 motherboard architecture
. While a Rev 2.0-specific PDF is difficult to find publicly, technicians often rely on the Rev 1.0 schematic
for most power rails and signal paths, as the core engineering remain similar Key Technical Details Motherboard Model: Compal CSL50 / CSL52 Common Applications: Primarily found in laptop series Major Components: Intel Kabylake/Skylake (often U-series) Dual-channel DDR4 slots Integrated UMA or Discrete GPU options Common Repair Points
Technicians working on the Rev 2.0 board frequently encounter "no power" or "no lights" issues Before diving into the schematic, you must understand
. Key areas to check based on community repair logs include: Primary Power Stage:
Verify 19V at the first input MOSFET. If it's blocked, check for shorts on the (a dual transistor often marked Power Rails: Confirm the presence of 3.3V and 5V standby voltages Component Testing: Low resistance on coil may indicate a fault in the PCH or related power ICs Where to Find the Schematic

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
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
: Includes HDMI (supporting up to 297MHz), USB 3.0, and Gigabit Ethernet (via RTL8111HSH). Critical Circuit Sections
Repair technicians frequently reference specific segments of the LA-E801P Rev 2.0 schematic to troubleshoot common power issues: Power Input (19V Rail) The "Rev 2
: The primary 19V line enters through the DC jack and passes through protection MOSFETs. A known troubleshooting point involves the transistor and the
chip (a dual PE642DT transistor) which often fails, leading to "dead" or "no light" symptoms. 3.3V/5V "Always-On" Rails
: The schematic details the step-down converters responsible for these standby voltages. Lack of 3.3V on the power switch is a primary diagnostic step for non-responsive boards. Discrete Graphics Conversion
: Technicians sometimes use the schematic to perform a "UMA conversion," which involves disabling the dedicated AMD GPU power rails (such as
) if the chip is shorted, allowing the laptop to run on integrated graphics. Troubleshooting & Common Faults La E801p | PDF - Scribd
A proper schematic file (usually a .pdf or .brd file) is not just a single page of lines. It is a detailed blueprint comprising:
Verdict: A competent, utilitarian design focused on stable power distribution and basic I/O management.
In the world of modern laptop repair, attempting to diagnose a dead motherboard without a schematic is akin to sailing across the ocean without a compass. For one specific, highly popular motherboard—the LA-E801P Rev 2.0—this document is the holy grail.
The LA-E801P is the primary motherboard used in the Dell Vostro 14-3458, Dell Inspiron 14-3458, and several other Dell 3000 series laptops. These are workhorses found in offices, schools, and homes worldwide. Consequently, they flood repair shops with common issues: no power, no display, fan spinning but no boot, and short circuits.
If you have searched for "la-e801p rev 2.0 schematic", you likely have a non-functional board on your bench. This article will explain what this schematic contains, where to find it, how to read it, and the most common faults you can fix using it.
