La-e801p Rev 2.0 Schematic Online

If you are working on a Dell Latitude 5289 2-in-1 or a similar Kaby Lake-based laptop, you’ve likely encountered the . For technicians and DIY enthusiasts, the schematic for this board is the "holy grail" of documentation, turning a guessing game into a precise repair process.

Since this board supports Kaby Lake processors, the power requirements are highly regulated. The schematic shows the multi-phase buck converters responsible for feeding the CPU.

If the laptop won't turn on, check the first and second MOSFETs (usually located near the DC jack) to see if they are passing the 19V rail through to the rest of the board. 2. The 3.3V/5V "Always-On" Rails la-e801p rev 2.0 schematic

If these rails are missing, the Super I/O chip (EC) won't have power, and the laptop will appear completely "dead." 3. CPU Core Power (VCC_CORE)

When you open the LA-E801P Rev 2.0 PDF, you should focus on these critical power rails and stages: 1. The DC-In and Charging Circuit If you are working on a Dell Latitude

The LA-E801P (often branded as the ) is a specialized motherboard designed for Dell’s ultra-portable 2-in-1 laptops. Because these devices prioritize a thin profile, the board is densely packed with surface-mount technology (SMT). Without the Rev 2.0 schematic, identifying a blown capacitor or a faulty MOSFET is nearly impossible by sight alone. Key Sections of the Schematic

Ensure you are using the Rev 2.0 file. Using a Rev 1.0 schematic for a 2.0 board can lead to incorrect voltage readings as components may have been moved or values changed to improve stability. the power requirements are highly regulated.

This article breaks down why this specific schematic is vital and how to use it to troubleshoot common power and display issues. What is the LA-E801P?
