broken sleep

Anybody else having trouble with sleep mode after "upgrading" to 8.1?

Screen sleeps ok, but PC doesn't. Hybrid is set to On, Hibernate to
Never; have tried wake timers both enabled and disabled.

The annoying part is that it was working perfectly before the upgrade...:-(

Does the video card have a driver ?

My backup PC has an old video card, and there
is no Win81 driver for it. The OS uses a VESA fallback
driver of some sort, with fixed 1024x768 resolution.
(Even though my screen native resolution is 1440x900.)
The screen is a bit slow to update/animate, due to
everything being emulated in software.

And that PC isn't showing a sleep option. While
this PC has a video driver, and it does show a
sleep option.

That's about all that stands out here, on the
"PC with no Sleep".

One potential reason for the driver situation being
a bit screwy, is they keep changing the version of
WDDM :-) Win81 uses a newer version (1.3).

The video card is an nvidia geforce gtx 460 with latest (331.65) driver.
Not exactly state of the art, but good enough. The odd thing is I can
manually put the damned thing to sleep (and I don't mean a hammer).

Same thing happened to me. I figured the power profile had been reset, but
it looked good so I made a random change, saved it, then reversed the change
and saved it again. So far, so good, after about 2 weeks.

That is a method that has worked of me in many similar settings
problems. I have no idea what kind of bug causes that sort of behavior
:-(

In an admin command prompt, try:

powercfg -requests

This will tell you if anything has requested a hold of your system and
keeping it from sleeping. Address anything that doesn't read "None."

In rare cases, it could also be your keyboard/mouse driver. You should
check the mouse driver/keyboard driver and make sure they are current and
will let the system sleep.

As a last resort for the keyboard/mouse problem, in "device manager,"
right click on the mouse or keyboard and choose properties. You must be
admin to see the tab. Click on the "power management" tab. Sometimes
unchecking "Allow this device to wake the computer" will let the system
sleep if you have a mouse/keyboard driver problem.

Of course if you do this to both, you may need to wake your system with
the power button, so it's better to get mouse/keyboard drivers that let
the system sleep properly.

It's probably not the mouse/keyboard, but that's a wild stab at it, if
powercfg doesn't turn up a hold sleep request.

Thanks for the inputs.. for info, powercfg returns system:none
awaymode:none, exe3cution:none, perfboost:none.
So no help there...

Will try the check/uncheck next and report back for any other hapless
sufferers...
