I have my laptop (XP SP3) set to go into Standby after 25 minutes of inactivity. With NIS 2009 installed, sometimes this wouldn't work, but it normally did. Since installing NIS 2010, I've left my machine running for hours and it never sleeps.
I've only seen it sleep twice: once when I changed the Standby setting to 1 minute (as a test) and the other time when I turned on Silent Mode.
I use a wireless network and my ethernet port is disabled so network activity shouldn't prevent the laptop from entering Standby.
Anyone else having issues with their PC not going into Standby with NIS 2010.
