Dell Precision 7520 Ubuntu 18.04 laptop with xrdp installed. Self built Windows 10 makes RDP Remote Desktop Protocol connection to Ubuntu machine on local network. Exactly at 30 minutes connection is dropped, Ubuntu goes in Suspend mode. Hit keyboard on Ubuntu machine and no problem reconnecting.
On Ubuntu 18.04 Settings->Power->Suspend & Power Button Automatic Suspend is set to 45 minutes on Battery Power. When connected through Win10 RDP the Settings->Power->Suspend & Power Button in not visible.
Dell Bios Power Management->Wake on LAN/WLAN is set to Wake-On-LAN 
Any ideas on how to override automatic suspend setting when connecting from Win10 RDP
