HP 15 EPV51 LA-G078P Schematic
Technical Specifications
Technical Summary
This Compal EPT51 reference design, documented as PCB number LA-G078P revision 0.3 dated January 5, 2018, is built around the AMD Stoney Ridge (FT4) processor platform. The discrete graphics subsystem utilizes an AMD R17M-M1-30/70 GPU with GDDR5 X2 or GDDR5 X4 VRAM configurations. System memory consists of two DDR4-DIMM slots operating in single-channel mode at 1866 MHz. The embedded controller is a KB9022, and the system BIOS is stored on an 8M SPI ROM. Audio is handled by an ALC3227 codec, while wired networking is provided by an RTL8111HSH-CG Gigabit Ethernet controller. A G753T11U thermal sensor monitors system temperatures, and an SLB 9665 TPM module is present for security. The design also includes an AK6485RB card reader, an AM1153 USB to SATA bridge, and a PI3PCIE3212 multiplexer for PCIe lane switching.
