Schematic — La-e801p Rev 2.0

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 adapter’s LED blinks or shuts off entirely when plugged into the laptop. The laptop shows no signs of life.

VIN passes through the entry protection MOSFETs. The schematic dictates the subsequent release of specific

motherboard . This specific board powers popular 15-inch budget and mid-range laptops, most notably the series and the HP 250 G6 . Equipped with 7th and 8th-generation Intel processors (ranging from Core i3-7100U up to i7-8550U) and DDR4 memory slots, this motherboard is prone to predictable electronic power failures.

The "LA-E801P" is the board number (PCB code) for a series of motherboards used in several HP laptop models, including the , HP 250 G6 , and HP 240 G6 lines, from around 2017 onwards. Specifically, the versions include CSL50 and CSL52 . Understanding the "REV 2.0" designation is crucial, as it signifies a specific revision of the board, and earlier versions (like REV 1.0) have different schematics.

Locate the +3VALW and +5VALW step-down regulator (often a Richtek or Texas Instruments IC).

The LA-E801P motherboard typically features an integrated System-on-Chip (SoC) architecture, combining the CPU, GPU (in UMA configurations), and Platform Controller Hub (PCH) into a single package. Core Hardware Specifications
