Expert Help Request: PC Wakes - "Unknown" Reason - same time everyday
All
Yeah yeah - I know - another "sleep" question :)
But this one - REALLY has me jacked up as I have pretty much investigated every possible angle here and have still come up dry:
Context - Windows 10 Pro 22H2 installed on a brand-new audio workstation (Jan 26, 2024)
Intel LAN - Wake on LAN is enabled for use with my endpoint management software. Of the three Power Management options - the first two are checked and only the "Magic packet" item is unchecked.
Wake Schedule - Endpoint software runs a script to "wake this PC every day at exactly 5:10am (which it does perfectly)
Sleep Schedule - Endpoint software runs a script to "sleep" this PC every day ay exactly 10:30pm (which it does perfectly)
Anomaly: At exactly 10:43pm - for at least the last week (but maybe longer) - the PC wakes and the wake source = "Unknown"
That is where I am at. What I have done so far - from most obvious to the very obscure:
1. Standard Power Settings adjustments (to ensure no wake timers or any other crap)
2. Dropping ALL sleep timers
3. Killing all possible device options (mouse, keyboards) that have a checkbox (or anything related to) "Allow this device to wake the PC etc etc"
4. powercfg /last wake
5. powercfg /wake timers
6. powercfg /sleepstudy (cool report that is so close but yet so far)
7. Deep Scheduled Task analysis with no obvious outliers (but this still my best guess)
8. Event Log analysis - daily/hourly exam with no clues
9. Several in-depth PowerShell scripts that try to pinpoint what task or what "unknown" force is occurring at exactly 10:43pm (Nothing found so far)
If this is NOT a mysterious scheduled task firing at 10:43pm - it can only be one other thing - a WOL request from my endpoint management system (Endpoint Central) which makes no sense at all as 10 other PC are part of its Wake/Sleep schedule and no others are waking at this oddball time. And ALL if them have the identical LAN interface power management options checked.
Or it is truly "Unknown" At my wits end here folks - is there anything else I can examine?
