BIOS.MiscSettings.InSystemCharacterization (Read or Write)
Description
When enabled, In-System Characterization (ISC) executes during POST upon detecting relevant
change(s) in system configuration to optimize system power and performance. ISC takes about 20
seconds to execute, and system reset is required for ISC results to be applied. The Enabled - No Reboot
option executes ISC and continues without applying ISC results until the next time system reset occurs.
The Enabled option executes ISC and forces an immediate system reset so that ISC results can be applied
right away. It takes the system longer to be ready due to the forced system reset. When disabled, ISC will
not execute.
R530, R530XD, R430, T430, R330, T330, R230, and T130 do not support ISC.

BIOS.MiscSettings.PowerCycleRequest (Read or Write)
Description
This feature allows you to mimic a one-time AC power cycle. You will rarely need to use this feature. You
may be directed to use it by Dell support. This feature is usually set to None. When you change it to
Virtual AC, the system will do its best to mimic a temporary removal of AC power from the system (the
AC Power Recovery feature will not be triggered by this action). The effect of this action is that some of
