4-pin ATX 12V connector located near the CPU socket. CPU Fan Header: 4-pin PWM header labeled CPU_FAN .
Used for dedicated graphics cards. (Gen 3.0 speed requires a 3rd Gen Ivy Bridge CPU).
You will never find a 300-page PDF manual for the 2AD5. Manufacturers do not print guides for a single radio chip. Instead, this chip is a component inside your laptop (e.g., an ASUS Zenbook or HP Pavilion). pegatron 2ad5 manual
The Pegatron 2AD5 is a micro-ATX motherboard built by Pegatron (a former manufacturing division of ASUS) for Hewlett-Packard. It serves as the foundation for many mid-to-high-end HP ENVY and Pavilion desktops, including the H8-1xxx and H9-1xxx series. Based on the widely-respected Intel Z75 chipset, it was designed to support Intel's 3rd-generation "Ivy Bridge" CPUs (Socket 1155). The board was typically paired with processors ranging from the capable Intel Core i5-3470 to the high-performance Intel Core i7-3770K. It represents a high-quality OEM component often found in capable and durable desktop systems of that era.

Remember: because this is an OEM component, always cross-reference with your HP computer’s service manual. Keep the CMOS clear procedure handy, know your SATA settings, and never flash an unverified BIOS.
The board features two 240-pin DDR3 DIMM slots configured for dual-channel architecture. 16 GB (2 × 8 GB modules) (Gen 3
Understanding the physical layout of the Pegatron 2AD5 is crucial for installing upgrades, troubleshooting hardware, or migrating the board to a new case. 1. CPU Socket & Power Delivery
