I ordered 8 Optiplex 390's, fast track, in December. Out of these 8 and 3 replacements, I have had 4 failures.
The units failed to boot after about 3 to 7 days of burn in. After escalation, Dell Engineering said "Until a permanent solution is provided, changing the BIOS setting for Power Management->Deep Sleep Control to “disable” may prevent this issue from occurring. " When the tech came out to replace the motherboard, he said that he has never seen a system with this setting enabled. And, it is true that the default is disabled. (Dell replaced 3 units and the last one, they sent a tech to replace the board). He had more to say, but I don't know if it was the straight story. It doesn't make sense. He said that with the setting enabled in the BIOS, the user must press the power button multiple times within a short time to effect a power on. While this would explain the systems failure to boot, it does not explain why they would first work, then stop. Or, that some of the units never quit. Go figure.
Anyone else in the same fix?
