Find the LCD_VCC rail (+12V or +3.3V depending on the panel) on the JEDP1 connector. If missing, look for a blown pico-fuse or a shorted MOSFET in the backlight circuit using the schematic. 3. Fan Spins But No Image (No POST)

: Typically supports Intel 10th Gen Core processors (Ice Lake). Board Revision : REV 1.0 is the most common version cited.

Here’s an informative feature on what the LA-H103P schematic is, its typical uses, and how to work with it legally and safely.

The schematic is a critical technical document for technicians and engineers repairing the Lenovo IdeaPad S340-15IIL Go to product viewer dialog for this item. (Ice Lake) laptop series. Specifically, the Compal LA-H103P board (Rev 1.0) Go to product viewer dialog for this item. is designed for 10th Generation Intel Core processors.

The "Always-On" voltage rails generated by the primary PWM regulator buck controller. These rails supply power to the Embedded Controller (EC) and power button circuit before the laptop is even turned on. Secondary Rails (S5, S3, and S0 States)

A schematic is a symbolic representation of the circuit, while a file (.brd or .asc) shows the physical layout of the components. Using them together allows you to:

Ultimate Guide to the LA-H103P Schematic: Repairing the HP 15-DY Laptop Motherboard

The LA-H103P does not use a traditional charger IC like the BQ24780. Instead, it uses a (e.g., TPS65987 or CYPD5225). The schematic reveals:

Note: If you are looking for a schematic file to download, try searching for the part number printed on the main BGA/QFP chip (e.g., RTD2025, TSUM56, etc.), as schematics are often indexed by the driver IC rather than the board model LA-H103P.

The designation is often found on:

Be extremely careful with free file download sites (e.g., "easyrepairfree.com", "pdf-manuals.com"). Many serve malware or ads. Use an ad blocker, and never download .exe files. Board files should be .pdf or .brd format.

If you need help tracking down a specific component value or testing a specific pinout on this motherboard, let me know:

You might wonder if you can repair a laptop without a schematic. For simple issues (like a broken DC jack), yes. For anything else, no.

Many specialized sites index Compal schematics for Lenovo S340 models. If missing, look for a blown pico-fuse or

The primary power rail generated directly from the AC adapter or battery. It distributes voltage to all major step-down switching regulators.

It is used by repair technicians, engineers, and advanced hobbyists to troubleshoot motherboard failures — such as no power, no display, short circuits, or damaged ports.
