Got up this morning and noticed that the monitor and keyboard on the machine I updated last night were both still lighted even though they should have been in sleep mode. The monitor screen was kind of dim and not brightly lit as when everything is active. I just now checked power settings in control panel and noticed that the option to set a time for the computer to enter sleep mode is gone. There is a setting for the monitor. In advanced options there is an option to turn off the hard drive but no sleep mode.
