My Win 10 laptop is supposed to serve as a server for another machine. So it needs to stay awake even if I am not on it. This is not happening and the machine may work for 2-3 hours or sleep after 5 minutes. No real pattern.
I have reset and tweaked Power Settings Plans to no great results.
What I do in the Events Viewer logs is:
Change Reason: System time synchronized with the hardware clock."
Information 2017-07-07 4:15:55 PM Microsoft-Windows-Kernel-Power 107 (102) The system has resumed from sleep.
Information 2017-07-07 4:15:53 PM Microsoft-Windows-Kernel-Power 42 (64) "The system is entering sleep.
Sleep Reason: System Idle"
Information 2017-07-07 4:15:53 PM Microsoft-Windows-Kernel-Power 40 (36) The driver \Driver\WSDPrintDevice for device SWD\DAFWSDProvider\urn:uuid:e3248000-80ce-11db-8000-30055c03575f/uri:e3248000-80ce-11db-8000-30055c03575f/PrinterService stopped the power transition.
The bit that is interesting is that \Driver\WSDPrintDevice always shows up before Sleep Reason: System Idle. I've disabled my printer driver, but that must not have been it because it's still happening.
I ve looked around some of the, many, sleep questions, but haven't found WSDPrintDevice mentioned.
How do I update/disable WSDPrintDevice?
Then again, maybe the WSDPrint is trying to resist going to sleep, rather than causing it.
As a work around, found @ http://www.softwareok.com/?seite=faq-Windows-10&faq=42, I am running powercfg -h off in the admin powershell console to disable sleeps.
