H Statement of Volatility
HP confirms that Intel-based HP 200 G1 MT personal computer contains DDR RAM 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, contain the following non-volatile memory: PCH Real Time Clock (RTC) battery
backed-up configuration memory (256 Bytes), DIMM Serial Presence Detect (SPD) configuration data
(256 Bytes per module, 128 Bytes programmable), and Serial Flash IC for System BIOS (64M Bits).
The volatile memory is cleared by removing power from the system for greater than 30 seconds. The
non-volatile memory on the motherboard is restored by following the steps below:
1. Download the latest BIOS for this system and operating system off of the HP website.
2. Follow the instructions on the website to flash the BIOS.
3. Enter F10 setup.
4. Select Default Setup > Reset Factory Settings as Default , and then select Apply
Defaults and Exit . Setup and Power-on password can be cleared by the BIOS Password Clear
jumper.
5. Power down the system and remove the AC power card. The RTC and Super I/O battery backed-
up memory is cleared by removing the battery found on the motherboard, allowing the board to
sit for greater than 60 seconds, and then replacing the battery.
The DIMM SPD EEPROM is not readily available to the user, however there are tools publicly available
to read and write this part. To eliminate the possibility that it could contain sensitive information,
remove the DIMMs or use one of these tools.
