La-e801p Rev 2.0 Schematic ((top)) -

Today, I wanted to take a moment to break down the schematic for this board, discuss the common failure points that aren't always obvious from a visual inspection, and explain why having the Rev 2.0 diagram specifically is crucial for a successful long-term repair.

Check the high-side MOSFETs connected to the phase coils. If a high-side MOSFET shorts out, it can bypass the regulator and shoot 19V directly into low-voltage components, which often destroys the CPU.

Unified Memory Architecture (UMA) using integrated Intel HD Graphics, or configured with a Dedicated Graphics chip (AMD Radeon variant depending on the BOM option).

: Following the schematic to the charging circuit, he found a charred resistor, PR702. It was supposed to be 10 ohms; it was now an infinite void. The Resurrection 💡 la-e801p rev 2.0 schematic

If the machine displays nothing, a clean bios dump (such as those requested on Badcaps ) is needed to re-flash the SPI chip. Where to Find LA-E801P Rev 2.0 Documents

Always-on rails that should be present as soon as the battery or charger is connected.

Search for "schematicslaptop" for repositories containing PDFs and .brd files.

Integrated Intel U-LV CPU (BGA package) handling both processing and Platform Controller Hub (PCH) operations.

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. Unified Memory Architecture (UMA) using integrated Intel HD

Use the "Find" function (Ctrl+F) in your PDF reader to locate the component ID (e.g., PL401) on the schematic.

: He probed the drain of the first MOSFET. Zero volts.

If you have a "Dead" board, start by checking the and the Charging IC (often an ISL or BQ series chip). The schematic will label these as PQ-series components. 3. Common Failure Points on the LA-E801P
