Did it work before? Have you installed any optional windows updates. You may want to try rolling back the graphics driver. You may also want to check if their is a firmware update relative to this issue for your computer at the support page.

Make sure you have Vista Service Pack 1 installed first.
You can reinstall all of your original driver through the program called Recovery Manager if an HP update truly messed up sleep mode.
It could the video card driver that got updated.
You you don't neccesarily need sleep mode then turn it off in the power options.
