Lae801p Rev 20 Schematic Better ((full)) [ 5000+ HOT ]

A frequent complaint is that 19V reaches the first input MOSFET, but nothing comes out on the source side. Beginners often replace the input MOSFET blindly, only to find the new one gets incredibly hot or continues to block voltage.

Light on DC jack turns on, but laptop does not post or spin fan.

When troubleshooting a "dead" or "no power" LA-E801P Rev 2.0 board, diagnostic efforts should focus on these primary rails and components:

Turn on only after the power button is pressed and the EC sends out the SLP_S3# and SLP_S5# sleep signals to transition the board into an S0 (full on) state. 3. Common Failure Modes on the LA-E801P Rev 2.0

If you are currently troubleshooting an LA-E801P motherboard on your workbench, tell me: A frequent complaint is that 19V reaches the

If you find a shorted rail but cannot see which component is failing, use a DC laboratory power supply to inject a safe, low voltage (e.g., 1V) into that dead rail. Watch the board under a thermal camera; failing capacitors or shorted MOSFETs will immediately glow hot.

The is an invaluable piece of diagnostic infrastructure for anyone serious about repairing modern HP laptops efficiently. By utilizing a matured schematic revision, you eliminate layout confusion, trace lines with confidence, and resolve tricky circuit issues far faster than using guesswork or outdated documentation.

laptops. It typically features an Intel 7th Gen (Kaby Lake-U) processor, such as the i5-7200U, and may include dedicated graphics like the AMD Radeon 530.

A high-quality schematic allows you to find the main current-sensing resistor directly after the input MOSFETs. Desoldering this resistor lets you isolate whether the short-circuit is at the input stage or deep within the main +19V distribution rail. RAM Controller Confusion ( G5616B )

It provides a more precise map of the power-on sequence, which is essential for diagnosing "no power" or "power-on, no display" scenarios.
