We just completed a deployment of the HP Elitepad 900 using CM2012 Standalone Media. I wanted to share an issue and solution I encountered: out of the box, the data/time was far off from the current time. This caused the task sequence to pause indefinitely, since the system time preceded the time the base WIM was created. Smsts.log displayed "Waiting for job status notification..." Set the current time on these if running from standalone media!!
