: Some E93839 boards, such as those found in the OptiPlex 980, feature the LGA 1156 socket and support first-generation Intel Core i3, i5, and i7 processors.
You should search for: or "Wistron 13269-1 Schematic" (Wistron is another manufacturer for these boards, and the boards are often interchangeable/identical in layout).
: As previously noted, E93839 is a regulatory number, not a part number, leading to confusion when searching for documentation. E93839 Motherboard Schematic
Several obstacles make obtaining E93839 schematics difficult:
The designation "E93839" is technically a UL (Underwriters Laboratories) certification number assigned to Foxconn (Hon Hai Precision Industry). This means the number can appear on several different physical board layouts across different Intel socket generations (such as LGA 1155, LGA 1150, or LGA 1151). : Some E93839 boards, such as those found
If the PCH is satisfied with system parameters, it drops its sleep signals, releasing SLP_S3# and SLP_S5# from low to high. Step 3: Main Rails Activation
Because "E93839" is the board code, searching specifically for that string can sometimes be difficult in public archives. Schematics are usually indexed under the laptop model name. Step 3: Main Rails Activation Because "E93839" is
Storage and expansion
One of the most practical applications of boardview files is identifying unmarked or cryptic components. A Dell OptiPlex XE2 user with an E93839 Amo327 board found two burned MOSFETs marked simply "(01)". Through community investigation and comparing physical locations (QP50 and QP61) with known schematics, the component was identified as an FDN340P MOSFET—though note the confirmation that the marking on the actual part was "340" rather than "01".
For those who successfully obtain an E93839 schematic and boardview files, the documentation becomes an invaluable tool for systematic troubleshooting. The following case studies illustrate how repair professionals and enthusiasts have used these resources.
A common headache is connecting a new case to this board. The Dell E93839 usually uses a non-standard, 5-pin or 10-pin front panel connector.
