Searching for a schematic using only "E93839" is like trying to buy car parts using only the name of the steel mill that supplied the metal. You must find the true motherboard model name. How to Locate the Real Motherboard Model A repair session should always use both together
Gives you a searchable logic map. It outlines component links, resistors, capacitors, and IC part numbers. You must find the true motherboard model name
A high-quality schematic allows you to trace these rails from the 24-pin ATX connector all the way to the CPU.
While specific layouts change across generations (such as LGA 1155 for Sandy Bridge vs. LGA 1150 for Haswell), Dell desktop motherboards sharing this UL marking follow a standard ATX/Micro-ATX power distribution architecture.
Technical information for this version includes details on the Intel Q45 chipset and support for up to 16GB of DDR3 RAM.
