Would appreciate anyones help. I have windows XP. When I hit start >turn off computer >stand by, the pop up disappears and I go right back to the desktop. The "restart" and "turn off" functions work but not the "stand by" function. I have already checked control panel >power options and all those settings work and are fine. My computer will eventually go into "stand by" and "hibernate" per the settings. I just want to be able to "click on" the stand by button and do it manually like I used to be able to do.
