Lae801p Rev 20 Schematic Better Hot! Jun 2026

But the killer feature? Rev 20 introduces a (C5, 10nF) between the two planes right at the controller IC. This provides a low-impedance path for high-frequency noise without creating a ground loop. This is better because it allows the module to pass EN55032 Class B emissions testing without external shielding—a feat earlier revisions could not achieve.

High-quality schematics include a Bill of Materials structure table outlining exactly which components are "Stuffed" (soldered) or "Un-Stuffed" (left empty) depending on whether the board is an Intel UMA or AMD Discrete graphics model.

Ensure the 3.3V and 5V standby voltages are present. A common failure point on this board is the source side of the power-in MOSFETs showing unusually low resistance (e.g., 7Ω), which often indicates a short circuit in the downstream rail. No Display Issues:

Good for viewing online, though searching requires a premium account. Search for "LA-E801P rev 1.0" or "1.1" as they often share 80-90% compatibility with rev 2.0. 5. Tips for Working with LA-E801P Schematic But the killer feature

Trace to the PQB11 MOSFET. If the resistor in the gate circuit is blown, the laptop won’t turn on. B. Power On, No Display (No DRAMRST) This is a very common issue on the LA-E801P rev 2.0

Video walkthroughs for common issues (like "dead" boards or charging problems) are available from repair educators like Laptex . This is better because it allows the module

: 19V stops right at the first or second MOSFET. The laptop behaves as if it has no battery or charger connected.
