Hot!: La-e791p Rev 2.0 Schematic Diagram
For troubleshooting "no backlight" or "no display" issues.
The LA-E791P (often codenamed C5V01 ) is a DDR4-based motherboard typically supporting Intel Skylake or Kaby Lake processors.
The (or similar) Super I/O chip is the brain of the motherboard's power management. The schematic shows exactly which pins handle the power button signal ( ON/OFFBTN# ) and the "All Power Good" signal, which tells the CPU it is safe to boot. 4. Signal Mapping and Connectors The Rev 2.0 diagram provides pinouts for: La-e791p Rev 2.0 Schematic Diagram
Understanding the Compal LA-E791P Rev 2.0 Schematic Diagram For laptop repair technicians and electronics enthusiasts, the is an essential roadmap. This specific motherboard—often found in the Acer Aspire A315-51 and A315-33 series —is a complex piece of engineering. Having the schematic allows you to move beyond "parts swapping" and perform precise component-level repairs. Technical Specifications Overview
2.0 (Includes specific circuit refinements over the 1.0 version). Architecture: Integrated SoC (System on Chip) design. For troubleshooting "no backlight" or "no display" issues
For data recovery or drive recognition problems. USB and Audio: Pin-to-pin mapping for peripheral ports. Common Troubleshooting Scenarios The "Dead" Motherboard
Laptops that won't charge or don't recognize the battery often have faults in the charging area. The schematic identifies the (commonly a BQ-series chip) and the MOSFETs responsible for switching between battery and AC power. 3. Super I/O and BIOS The schematic shows exactly which pins handle the
Using the schematic, a technician will first check the at the entry MOSFETs. If the 19V is present but the laptop doesn't start, the schematic points you to the 3V/5V Regulator IC . By measuring the Enable (EN) pins defined in the Rev 2.0 document, you can determine if the IC is faulty or if it’s simply not being told to turn on. Short Circuit Detection
Always pair this schematic with the Boardview (.CAD or .BRD) file if available. While the schematic tells you how components are connected electrically, the Boardview shows you exactly where they are physically located on the PCB.
