I have a Dell Optiplex 755 mini tower pc and within the last month it keeps going into sleep mode even though I have the power options in xp OS set to always on and hibernate is disabled. I have checked within bios and the powers settings are like my other 755s that dont go into sleep mode.
This is a problem because I have to remote into this workstation and if it is in sleep mode it wont alow me to remote in. When I go to look at it the tower power button is flashing green and once i click the mouse a few times then it comes right up. It seems this may have started after upgrading the bios to A21, but I have other 755s that are upgraded to the new bios and do not have this problem.
Does anyone have any recommendations on keeping the pc from going into sleep mode?

Thanks for your reply!
The issue is not with remoting in, because I can remote in fine when the pc is awake, but with the computer going into hibernate/sleep mode even when it is not checked in power settings. This causes the pc to go offline, so I'm assuming it is going into hibernate because it seems to shut everything down when not in use. When I go to check the pc the tower power button is flashing green and if i touch the mouse a few times then it comes up.
