auto-sleep don't work no more

[Shoe]

For no particular reason, you just reminded me of a period when I couldn't
get sleep to work automatically, and when sleep wasn't set, even the screen
saver would fail to happen.

I then noticed that if I set the timeout to less than 5 minutes, screen
saver or sleep would work, and eventually I began to suspect my wireless
mouse and keyboard. I plugged in my original wired items, and the problem
went away. I had already turned off the Wake on LAN and similar settings to
no avail.

Other KB/M brands were OK.

To summarize the above long story: some devices (in my case a wireless
mouse/keyboard combo) call home periodically, which would wake Windows up
or make it think the computer was in use.

Interesting. I use a Logitech wireless keyboard and mouse, but that
must not be the problem because sleep sometimes works automatically
and always works manually. This does bring to mind another issue
though. When the computer sleeps, USB shuts down, so I cannot wake it
with the mouse. I have to push the power button. Any thoughts about
how to get the mouse to wake it up?

Have you looked at the two options "Allow the computer to put this
device to sleep" and its companion "Allow this device to wake the
computer"?

(Link is probably not Win7 specific, but the options likely still
exist.)

Oh, good. Then I'm OK until January 1st!

In Device Manager under Human Interface Devices, everything labeled
"HID-Compliant ..." has the Power tab with that option on this Win 7 Home
Premium.

I also have a heck of a lot of devices there, left over from plying with my
problem above, I guess. Wish I knew which ones to kill

For information purposes (I would be grateful if people who come here in
order to be sneery and rude would just ignore any message I write and
instead ponder awhile on why Usenet is dying) if one visits the command
prompt and type:

powercfg -energy

you will generate a Power Efficiency Diagnostics report. powercfg has
several other modes of operation as well as -energy.

Of particular interest might be powercfg -a

which will tell you what sleep states are possible. Not all PCs will allow
all and using the command that way will tell you what is available on your
machine. It is of course pointless setting any power options without first
doing that (unless of course there is another way which I don't know about).
You will probably have to be in admin mode or elevated or whatever the thing
is called in order to use some features of powercfg.
