I have recently built my computer. This is the first time for me. It is up and running just fine however one feature I like to have is the ability to put my system to sleep. How do I make this happen. My keyboard has the sleep button and of course I should be able to access that option through the start button but it does not work. I have looked through all options in the bios and see nothing that pertains to this. Am I overlooking something in bios or do I do this some other way? Please help.
