PC wakes itself up

Hi,

Often when I hibernate my PC, it then takes it upon itself to wake
itself up shortly after. How can I find out what is causing this?

Thanks

Open a command prompt with elevated privileges and enter this command:

powercfg ?lastwake

The last device that woke up the system will be shown.

To find out which devices are enabled to wake up the PC, enter this
command

powercfg -devicequery wake_armed

In addition to Ken's advice, it's a good idea to
disable the mouse for that functionality and only
use the keyboard. Small vibrations can often
cuse enough mouse movement to cause a startup.

I would do the mouse and the NIC.

In Device Manager (right-click Start to find it), there
will be an entry for the mouse, and one for the NIC.
You do Properties on the particular mouse entry, and
there is a Power Management tab. *Untick* the
"Allow this device to bring the computer out of standby".
Click OK.

On the NIC, there can be two tick boxes. The "Allow the
computer to turn off this device to save power" only
applies in the sleep/hibernate state (the NIC LED should
go off on the router, at shutdown). If that box is ticked,
and the NIC has power while sleeping, then you want to *untick*
"Allow this device to bring the computer out of standby".
Click OK.

And you only need to disable keyboard waking, if you own a cat :-)
The keyboard can wake the computer too.

And mice come in different flavors. My Logitech, the optical
sensor is totally disabled in sleep, but the mouse buttons
still work. My Logitech, I don't have to untick the box for
it. The Microsoft USB mouse on the other hand, the blue LED it
uses, it flashes about once a second while sleeping. And it
is armed for vibration, and has to be disabled in Device
Manager.

The LastWake method is good, for reducing your work
to a minimum. But while you're in Device Manager, you
can also check that your mouse/keyboard/NIC are the way
you want them.

Disabling wake up for mouse and NIC seems to have done the trick.

The command prompt thing doesn't work, even when I run as administrator.
I get the error "invalid parameters"

I think there was a typo, should be:

powercfg -lastwake

powercfg -devicequery wake_armed

On a particular OS, you can try

powercfg /?

as those two symbols are the canonical help request
for Windows applications.

Linus has "--help" or "-h" and depending on
where a Windows program has come from, it might
use options like that. But if Microsoft writes it,
then expect /? to work.

Once you consult the help, you can discover whether
the parameters to be passes are delineated by
a leading "/" or by "-". By changing how this is
done, from one OS to the next, it can lead to a
lot of confusion.

Using the actual application help, should show
you how to use it.

On much older Windows, some packages include a .chm
help file. Clicking on one of those, can give you
various bits of help too.

Even "dir" has help, and I'm not afraid to use it.

dir /?
