Subject: Statement of Volatility – Dell OptiPlex 3010

To whom it may concern:

The Dell OptiPlex 3010 contains both “volatile” and “non-volatile” (NV) components. Volatile components lose
their data immediately upon removal of power from the component. Non-volatile components continue to retain
their data even after the power has been removed from the component. The following volatile and NV
components are present on the Dell OptiPlex 3010 motherboard:

All other components on the motherboard will lose data once power is removed from the system. Primary power
loss (Unplug the power cord and remove the battery) will destroy all user data on the memory (DDR3, 1600/
1333MHz). Secondary power loss (removing the on board coincell battery) will destroy system data on the
system configuration and time-of-day information.

In addition, to clarify memory volatility and data retention in situations where the system is put in different ACPI
power states the following is provided (those ACPI power states are S0, S1, S3, S4 and S5):

S0 state is the working state where the dynamic RAM is maintained and is read/write by the processor.

S1 state is a low wake-up latency sleeping state. In this state, no system context is lost (CPU or chip set)
and hardware maintains all system contexts.

S3 is called “suspend to RAM” state or stand-by mode. In this state the dynamic RAM is maintained. Dell
systems will be able to go to S3 if the OS and the peripherals used in the system supports S3 state.

Windows 7, Ubuntu support S3 state.

S4 is called “suspend to disk” state or “hibernate” mode. There is no power. In this state, the dynamic
RAM is not maintained. If the system has been commanded to enter S4, the OS will write the system
context to a non-volatile storage file and leave appropriate context markers. When the system is coming
back to the working state, a restore file from the non-volatile storage can occur. The restore file has to be
valid. Dell systems will be able to go to S4 if the OS and the peripherals support S4 state. Windows 7,
support S4 state.

S5 is the “soft” off state. There is no power. The OS does not save any context to wake up the system.
No data will remain in any component on the system board, i.e. cache or memory. The system will require
a complete boot when awakened. Since S5 is the shut off state, coming out of S5 requires power on
which clears all registers.
