If you disable the Resume on Time field in System Setup, the same field in
PowerProfiler is also automatically disabled. An easy way to work with these
two fields is to set the resume time to 0 in System Setup and set the actual
resume time that you desire in PowerProfiler.
For more information on PowerProfiler, see the Help option in the PowerProfiler
software.

PowerProfiler maintains the accuracy of the system clock
when the computer resumes from rest mode. If PowerProfiler
is closed or removed from your hard drive, your system clock
may not be accurate when your computer resumes from rest
mode.
