Thanks for the suggestions. I've looked at the tutorial and have checked
power management settings for my network cards. I was able to start the UPnP
service and my computer can now sleep. I'm not sure what's going on with
that. I think whether or not a particular service was affecting the ability
to manually enter sleep was contextual or based on which other services were
disabled or enabled.
Basically, to solve the problem of not being able to enter sleep I first
used msconfig to disable startup items and services. I was able to re-enable
startup items and still enter sleep. Then I enabled services in blocks of
ten or so services. Both UPnP and Terminal Services were in the same block
of ten. I then started singularly enabling services in this last group. Both
UPnP and Terminal Services prevented sleep mode when adjacent services were
disabled. I was able to enable every last service except these two. At that
point, enabling UPnP no longer caused a problem (i.e. it only was a problem
with various other services disabled). I haven't re-enabled Terminal
Services yet so maybe that will work now. If I can re-enable this last
service, the net result will be that I haven't done anything to my computer.
Perhaps disabling and re-enabling various services altered the startup type
(e.g. delayed startup) and something along those lines corrected the
problem. Anyway, a pain in the a** but problem appears to be solved. And
after entering sleep, my computer will even automatically hybernate after
prolonged inactivity. Never had that working before.
It would be nice for MS to engineer an applet that can diagnose power
management problems given how pervasive they are for everyone.
