Dell OptiPlex 3010 Statement of Volatility - Page 2

Description RTC CMOS Reference Designator BATTERY Volatility Description User Accessible for external data Volatile Battery back-backed No CMOS memory 256 bytes Stores CMOS information Remedial Action (action necessary to lose data) Removing the on board Coin Cell battery Video memory - type - see next column UMA architectureuses system DDR3. Volatile memory in off state. No UMA uses main system memory size allocated out of main memory. Hard drive User replaceable Non Volatile magnetic media, Yes various sizes in GB Enter S3-S5 state below. Low level format CDROM/RW/ DVD/ DVD+RW/ Diskette Drives User replaceable Non Volatile optical/magnetic Yes media Low level format / erase 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. DELL CONFIDENTIAL Page 2
