I really do believe it was the 1394 port that was causing the problem. I can now put my computer to sleep as I did with all the builds prior to 1903 and it will wake up and run when I wiggle the mouse or hit a key on the keyboard. Must have gotten a new driver is my thought. Windows took an extra long time to start. I reconnected the 1394 jack knowing this was the problem. Booted it, put it to sleep, woke it up and IT WORKED. I then disconnected the wires from the motherboard coming from the multifunction card reader which has 2 sound jacks, 3 usb connectors, 1 eSATA connectors as well as all the different card slots.

I then disconnected the wires from the motherboard coming from the front of the case (2 sound jacks and 2 usb ports.) That also did nothing. I opened up the computer and disconnected both DVD drives, my second hard drive, unplugged the sound cord, and disconnected the ethernet cable. Problem: When waking computer from sleep in Windows 1903, 1909, 2004 builds, the computer will wake but nothing will happen. (Well, annoyance, mild discomfort and slightly higher electrical bill, really.)

So fingers crossed someone over here knows the solution or at least shares in my pain. Turning to the internet for a solution isn't really helping either there's a lot of dodgy websites offering, uhh, 'advice' (and dubious software to install), seems full of 'independent experts' who just want people to reinstall all the stuff that wasn't touched in the update (or just Windows in general) and any answers here on stackexchange (sub)sites are all older then the most recent Windows 10 update which introduced the problem. Now since this update changed a few of my settings without my consent (apparently, my way of alphabetically looking at files and folders in the Windows Explorer needed reevaluating, as did my choice in image viewer thanks, buddies at Redmond!) I immediately checked my Power Settings.

If it doesn't then it will lock my PC, show the login screen and just. Ever since the most recent Windows 10 update (1909) whenever I try to either shut down or put my PC into sleep mode, there's a rough 50/50 chance it'll actually do it.

Windows 10 won t go into sleep mode
