We have several Dell Optiplex GX520's on the network running Windows XP pro. They randomly fall into sleep mode. Moving the mouse will not wake them - you have to push the power button to get them out of sleep mode. Also we are not able to remotely wake them to do patch updates or remotely use them in general. The power scheme is set
to 'always on'. Hibernation is disabled. Hard disk set to never turn off. System set to never go to standby mode. And pressing the power button is set to power off. With all this the machines keep going to sleep. The BIOS settings are also set to WAKE ON LAN.
Has anyone else experienced this issue? Any ideas or suggestions? Thank you for your time.
I've encountered that problem with several other makes and models - including some Dell Optiplex models.
I generally just go into the control panel Power applet and disable those options.
Not much insight, but fewer problems afterwards.
