E93839 Motherboard Schematic [2025]

If you cannot find the exact schematic, search for the (e.g., JMicron JMS567). A generic datasheet provides the pinout and typical application circuit, which is 80% identical to the E93839 implementation.

If you are moving this motherboard to a new case, the front panel header is often a proprietary block rather than standard ATX. For the most common Dell E93839 variants, use this typical 9-pin layout: Pin 1 & 3: Hard Drive LED (HDD LED) Pin 2 & 4: Pin 5 & 6: Power Switch (Momentary contact) Reserved (No pin) Pin 8 & 10: Often jumpered or ground-linked for proprietary sensing Some HP variants use an 18-pin P5 connector E93839 Motherboard Schematic
