P71 won't go to sleep when using external monitor


I have a P71 with Windows 10 Professional. It is set to go to sleep after 15 minutes when plugged in. When I am using the laptop screen that actually happens; however, when I use an external monitor (and the laptop cover is closed) nothing happens when the deadline is reached. Any suggestions?

Re: P71 won't go to sleep when using external monitor

Dear bostjanv,

development team had tried to duplicate your symptom but no success, they can enter sleep after 15 min. at their environment.   ( Win10 Pro version 1703, Graphics driver Intel: & nVIDIA:, BIOS: v1.05 / v1.11, Ext. Monitor: LG 27MU67-B, Lid Closed, Ext. Monitor via DisplayPort/HDMI/Type-C to DP, no network (Ethernet, WiFi, WWAN) connected, no USB device connected )

If you connected any network devices or USB devices, can you try to disconnect/remove them ?
