At p. 35 of the Complete Handbook of jv16 PowerTools 2008 I read this passage (see attachment)

Well, I might be wrong, but in version 2008 of the PowerTools that "System Health Indicator" is not showing anymore in the Scan Report.
That feature seems to be gone there...
The Handbook should be modified, but there are several other issues in that Handbook too :(
