  1. Hi Guys, I too have a Optiplex 755. I have almost all hardware functioning in the DSDT - USB/USB2, nVidia Graphics, SBUS etc. However, I still can't get it to wake from sleep. I just get the black screen and have to hard reboot. When it reboots (after sleep only), the BIOS changes the Ethernet setting to either OFF or PXE. I assume that it is the integrated Ethernet causing the wake issue. Is there a DSDT patch for the integrated graphics? I can't seem to find any reference to it in the DSDT. Thanks again Rob PS. I tried all the DSDT's in this thread - no soup. I have Bios A19 Desktop version of the 755.

    EHCI Details Missing in DSDT

    Hi All, Has Anyone found a way to add USB2 EHCI to an extracted Dell Optiplex DSDT? I have the same problem with my 755. Perhaps it was b/c I extracted A09 BIOS? I have recently upgraded to A19 - should I re-extract DSDT? Thanks in advance!
