Technical Specifications
Technical Summary
This Compal LA-H791P motherboard, revision 0.2, is designed for the EH7LW/EH5LW/FH5TW/EH7LC/EH5LC platform and dated 2019.05.29. The platform is built around an Intel Whiskey Lake U or Comet Lake U processor paired with a Cannon Lake PCH-LP. Graphics are handled by a discrete Nvidia N17S-G0/G2 GPU with GDDR5 memory. The system memory architecture includes one DDR4 SO-DIMM slot and onboard DDR4 memory configured as 4G or 8Gbx16 in an interleaved dual-channel setup. The embedded controller is an ENE KB9022. The BIOS is stored on a 128Mb SPI ROM. Audio is provided by a Realtek ALC255 codec, and networking includes a Realtek 8111H Gigabit LAN controller with CNVi wireless support. A Realtek RTS5140 card reader is also integrated.
