Statement of Volatility - Sprout Business PC

HP confirms that Intel-based business desktop HP Sprout systems contain DDR3 volatile memory (memory amount depends on the customer configuration). In addition, the motherboard in the condition originally shipped without subsequent modification or the addition or installation of any applications, features, or functionality, contains the following nonvolatile memory: Real Time Clock battery backed-up configuration memory (256 Bytes), DIMM Serial Presence Detect (SPD) configuration data (256 Bytes per module, 128 Bytes programmable), Serial Peripheral Interface (SPI) ROM for System BIOS (16M Bytes) and Super I/O’s: masked keyboard ROM (overall 2K Bytes).
The following procedure shows the steps that should be taken to restore the Non-Volatile memory found in the Intel-based HP Sprout systems.
  1. Download the latest BIOS (system ROM) from the HP website.
  2. Follow the instructions to flash the BIOS that are found on the website.
    Flashing the BIOS will reset it back to factory settings.
  3. Turn on the system, and while system is powering on, and after the HP splash screen, press the F10 key to enter BIOS setup screen.
  4. Select Security > System Security from the main menu. If the Embedded Security Device Support option is set to “Disable”, skip to step 7.
  5. To erase all security keys from the TPM:
    Under Embedded Security Device in the System Security menu, configure Reset to Factory Settings to Reset.
    Although the TPM security keys will be cleared, data in the non-volatile memory indices may not be. Data stored in these indices should not contain security sensitive information. If an application locks down and secures the non-volatile indices, these indices cannot be cleared.
  6. Press F10 to accept changes.
  7. To clear the secure boot key database:
    1. Enter the F10 setup utility.
    2. Go to the Security menu.
    3. Select Secure Boot Configuration.
    4. In the Key Management section, select clear Secure boot keys.
    5. Use space key to select clear.
    6. Press the F10 key to accept changes.
    7. From the main menu select File > Save Changes and Exit.
  8. If the Ownership Tag or Asset Tag is set, manually clear it under Security > System Ids.
  9. Select File > Save Changes and Exit.
  10. To clear the setup or power-on passwords if set, and clear any other settings, power down the computer and remove the AC power cord and the computer hood.
  11. Locate the CMOS+PW header and jumper.
    The password jumper is blue so that it can be easily identified. For assistance locating the password jumper and other system board components, see the system board components image at System board callouts.
  12. Remove the jumper from pins 4 and 6.
  13. Place the jumper on pins 2 or 4.
  14. Replace the memory cover and rear cover and reconnect the external equipment.
  15. Plug in the computer and turn on power. Allow the operating system to start. This clears the current passwords and disables the password features.
  16. Enter the F10 setup utility.
  17. Select File > Default Setup > Restore Factory Settings as Default. This will set the default settings back to the factory defaults.
  18. Select File > Apply Defaults and Exit.
  19. Shut down the computer, unplug the power, and disconnect the external equipment.
  20. Remove the rear cover.
  21. Place the jumper back on pins 4 and 6.
  22. Replace the rear cover.
If Computrace is enabled on the computer, see the service provider for instruction to disable the feature.
