If Windows XP is hibernated while Emacs 23.2 is running, Emacs gets
the <sleep> event which by default is undefined, so Emacs beeps before
hibernation and displays "<sleep> is undefined" after Windows is
resumed; I think <sleep> should be ignored by default. Also, if the
Emacs window was maximized before hibernation, it isn't restored to
quite as it was; its size is reduced slightly and it's surrounded by
the usual window border.

(I'm going through old bug reports that unfortunately didn't get any
response at the time.)
This seems like a reasonable thing to add to global-map (i.e., ignoring
[sleep]), but is it common for Windows to send a [sleep] keystroke to
apps before hibernating?

I don't know, FWIW, and couldn't see where we any w32 code to inject
that event when the system is about to hibernate. Maybe I'm missing
something.

Is it possible that the OS just sends a [sleep] event to all clients
when it's about to hibernate? It would be a pretty simple interface for
notifying apps instead of using signals or a message bus...

Maybe, I just don't know. AFAIK, the message sent in that case is not
processed by Emacs to generate a 'sleep' function key, we only
generate that when the actual "sleep" key on the keyboard is pressed.

On GNU/Linux, it's easy enough to inject events into the event queue of
a process that's indistinguishable from an actual keyboard event, so I
was assuming that Windows also had such a thing.

It does. It's just that I don't see that particular message handled
anywhere in our sources which handle various Windows messages, so I
wonder how did the OP get the 'sleep' function key in the first place.
Maybe he just pressed the Sleep key...

It's possible.
Does anybody here have access to a Windows laptop that goes to sleep
when you close the lid? Could you try to do that and see whether Emacs
gets a [sleep] event that it then complains about?

I do at work, what must I do? What should I inspect when coming back
from sleep?

The bug report states that Emacs says
"<sleep> is undefined"
when the lid is opened (and Windows has resumed from sleep).

Had my normal Emacs running and started one emacs -Q. Closed the lid for
a while to go to sleep. When back I
could not see anything about sleep in the instances. I checked the
messages (`view-echo-area-messages`).
Here is some info from the emacs -Q instance:

Thanks for checking. Since this problem seems unreproducible, perhaps
it was just something Windows did in one particular old version? So I'm
closing this bug report.

The OP says nothing about a lid. (And I wouldn't expect opening a lid
to wake up from hibernate, though maybe it's possible to configure
things that way)
