My Dell Optiplex GX520 goes offline
I have an Optiplex GX520 that goes offline when screen saver kicks in and when on idle for for than 30 mins. Power settings are as follows:
Turn off monitor: never
Turn off hard disks drive: never
System Standby: never
Notes: When the PC goes offline the EU does not have access to the LAN.
Are there any settings that I may need to check i.e BIOS? The EU has to reboot everytime she is away for more than an hour. Any suggestions?
