Hi Rich and John,
that is partially right. For connected
devices like serial ports the power save options are not in play
as having a connection open is enough to stop power saving. For
audio streams there is no connection as such, an application
requests or subscribes to a device stream. Those streams source or
sink data to a shared resource and Windows will power that device
down without regard for any application using it. Applications are
not notified when audio streams are shut off by power saving.

There are settings that can and should be changed to prevent
Windows from putting USB devices to sleep unexpectedly. There is a
nice summary at
These settings changes should be applied on any Windows computer
that is being used for real-time amateur radio activities.

Ask yourselves, why in the hell are these
computers going to sleep at all?
The affected components are obviously being
used; as proven by the fact that wsjtx quits working when
those various components (audio, video, usb, etc.) go off
into never, never land. Since wsjtx is constantly running
& using resources - nothing should be timing out!
Given, ms sucks and they have made a crappy
system that doesn't work well most of the time.
Is there perhaps some coding that wsjtx can
use to send more robust signals thru the the computer
system, so that it can't go to sleep?

I was just
about to follow up on a post I made earlier, actually
several. My receive was locking up after a period of time
with new Windows 10 computer. I'm not an IT guy so I was
confounded. I finally discovered it was the sleep mode on
Winows 10. I don't think I never had my Windows 7 desktop
or laptops go into sleep mode. In fact, I'm not sure I knew
it existed. I leave them on all the time. Anyway, I
started fooling around with sleep mode and it appears that
was the problem, I hope. Just actually came to that
conclusion this morning. Thanks to all who tried to help me
