I have a HP Slimline Pavillion. Windows 7.

I've been reading about sleep buttons and hybrid sleep buttons and hybernation and for the life of me I can't find any buttons.

I went on google and it said to go to Start, then find an image of a lock and then next to that image, click on hybernation.

What image? I have no lock image, no thing that says sleep, or hybernation.

I just want to learn where these things are.

Thanks so much
