Some verified high-quality schematics are shared via Google Drive links in specialized repair groups. 3. Key Technical Specifications (LGA 1155 Version)
Dell hides this jumper in obscure places. Older docs said it’s near the SATA ports. The updated schematic explicitly places it at – located behind the PCIe x16 slot, near the battery. JMP1 pins are normally open; shorting them for 10 seconds resets the ME region. dell e93839 motherboard schematic updated
Look for a small white sticker with a barcode. The DP/N is usually a 5-character code (e.g., GM819 or 01LM431 ) following the "CN" country code. Some verified high-quality schematics are shared via Google
Once you obtain the schematic, focus on: Older docs said it’s near the SATA ports
According to the updated service guides for the E93839, the primary point of failure is the .
: Uses the 0YNVJG board with an LGA1151 socket, Intel Q370 chipset, and DDR4 memory.
A common failure on the E93839 is the SATA ports dropping offline. The updated schematic reveals two zero-ohm resistors (R607 and R608) on the +5V_SATA rail. These act as fuses. Old schematics omit them entirely. Now you know to check continuity across those resistors first.
