Windows 7 Ultimate 64 bit won't go in standby

The only other thing I can think of is look in Event Viewer after you click on Hibernate.
See if there is any error there.

Can i reinstall windows 7 without delete software an programm actually install.

With a usb key i can't update.

I agree with Layback Bear.

It's not normal to have W7 Ultimate on a pre-built (HP) PC.
Who installed Ultimate, and do you have the license key ?

Yes i have licence key

I have installed Ultimate 7 normally.

This is not the problem

Standby works normal

I don't understand the problem about the license key.

If you want i can send you photos for box and card with serial (serial license key will be hide naturally).

Thanks for you help :)

I didn't mean it's a problem.
I just said it's unusual and asked a question.
No need to send photos, and DON'T EVER post your license key or give it to anyone.

So the PC sleeps, but does not hibernate, right ?

You could try manually running the Hibernate command to see if it shows any errors.
To do this, open a Command Prompt window and run this command:
shutdown /h

strage message : "impossible to find specificate file (2)"

That is strange, i never heard of this before

Lets try adding the FORCE option to the command and see what happens.
Try this command:
shutdown /h /f
