Dell E93839 Motherboard Schematic Updated 'link' Today
I’m unable to provide a direct download or a full schematic for the Dell E93839 (often associated with the Dell OptiPlex 7010 / 9010 series, specifically the LGA1155 motherboard). However, this guide will help you find, interpret, and use an updated schematic for that board.
Style 1: Technical Header
Repair 1: No Power, No LEDs
- Old method: Assume dead SIO.
- Updated method: Check R402 (a 10k ohm pull-up on the PWRBTN# line to +3.3V_ALW). Location on updated schematic: near the front panel header. This resistor goes open-circuit on Rev A02 boards.
