TPM 1.2 (Trusted Platform Module) Security Device This device (identified as U_TPM) stores TPM configuration data used by the hardware and the security software offered by Dell. Encrypted user keys generated by the TPM device for use by the security software are stored in this NVM. SAS Controller The SAS Controller is identified as U407 U408 on the motherboard. U407 is a 16Kbytes EEPROM device, and U408 is a 16 Mbytes NOR Flash device. The U407 contains required configuration data to initialize default PLL settings, clock dividers, PCI-E configuration settings, and various other configuration settings. USB3.0 Controller EEPROM The USB3.0 Controller EEPROM is identified as U97 on the motherboard. It is a 64 Kbyte device. The USB3.0 Controller EEPROM stores firmware with vendor specific configuration data. All other components on the motherboard will lose data once power is removed from the system. Primary power loss (unplug the power cord) will destroy all user data in the main system memory (DDR3 DIMMs) and the on-board graphics and storage interface devices. However, the user should note that under some circumstances (for example, cold temperatures) the DDR3 DIMMs may retain their data for a significant amount of time - up to several minutes. That may potentially allow the DIMMs to be removed from one system and installed in another without loss of the data contained in them. Secondary power loss (removing the on board coin-cell battery) will destroy system data in the PCH (platform controller hub), including time-of-day information. There are other volatile and non-volatile components on the devices or peripherals attached to the motherboard: The Video Card contains volatile and non-volatile memory components. The volatile frame buffer memory will lose data once power is removed. The nonvolatile memory (Video BIOS) stores only video card setup information. The video BIOS is not accessible by the user. The CD-RW/Diskette Drives/DVD-R/W/Blu Ray DVD-R/W are input/output devices, whereas the DVD-ROM is an input device only. All data is processed through cache (volatile) memory. Any associated internal NVRAM is factory programmed, does not contain any user data, and is not accessible by the user. The SAS and/or SATA Hard Drives and optional storage controller cards store nonvolatile data. All data is processed through cache (volatile) memory. Any associated internal NVRAM is factory programmed, does not contain any user data, and is not accessible by the user. These devices may be removed. The Monitor may retain "Burn-In" images after long periods of displaying static data. If any burn-in images exist, they can readily be seen using simple procedures. NV memory components are used for storing monitor calibration/configuration data & are not accessible by the user. To help clarify memory volatility and data retention in situations where the system is put in different ACPI power states, the following information is provided regarding ACPI power states 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.
