Created attachment 281701 [details] Output of hwinfo Hi, when the PC is sleeping and the TV gets powered on it resumes from S3. The board is an ASROCK Z370 Gaming-ITX ac with newest BIOS (3.30). I've narrowed it down to the HDMI connection between TV and IGP. Test: - Unload iwlwifi and btusb module, so PC can't be waken through WiFi or Bluetooth. - Suspend PC (S3). - During sleep disconnect all external connectors (except HDMI and power). - Power on TV Result: PC powers on Do the same as above, but also disconnect HDMI, and the PC sleeps on. There is no feature in the BIOS which refers to "Wake On TV" - like Intel NUC series. I've selectively disabled all wake up sources and succeeded with disabling XHC. I don't understand why HDMI/LSPCon is somehow connected to USB wake up. I'd like to wake the PC via USB keyboard, but of course this doesn't work when disabling XHC as wake up source. Best regards Marc
