H Statement of Volatility Thin Client products typically have three types of memory devices namely, RAM, ROM, and Flash memory devices. Data stored in the RAM memory device will be lost once the power is removed from the device. RAM devices could be powered by main, aux, or battery power (power states are explained below). Therefore, even when the unit is not connected to an AC outlet, some of the RAM devices could be powered by battery power. Data stored in the ROM or Flash memory devices will retain its data even if the power is removed to the device. Manufacturers of Flash device usually specify a period of time (in the order of ten years) for data retention. Definition of power states: Main Power: Power available when the unit is turned on. Aux or Standby power: Power available when the unit is in off state when the power supply is connected to an active AC outlet. Battery Power: Power from a coin battery present in the Thin Client systems. The table below lists the available memory devices and their types per the models. Please note that the Thin Client systems do not use traditional hard drives with moving parts. Instead, they use flash memory devices with an IDE/ SATA front-end interface. Hence, the operating systems interface with these flash devices similar to a regular IDE/ SATA hard drive. This IDE/ SATA flash device contains the image of the operating system. The flash device can only be written by an administrator. A special software tool is required to format the flash devices and clear the data stored in them. Please find below a list of steps that should be taken to update BIOS and use it to set the BIOS settings to factory default settings. 1. Download the latest BIOS for your model off of the HP website. Download the latest BIOS (system ROM) from the HP website. Download the latest BIOS for your model off of the HP website. 2.

Statement of Volatility
Thin Client products typically have three types of memory devices namely, RAM, ROM, and Flash memory
devices. Data stored in the RAM memory device will be lost once the power is removed from the device. RAM
devices could be powered by main, aux, or battery power (power states are explained below). Therefore, even
when the unit is not connected to an AC outlet, some of the RAM devices could be powered by battery power.
Data stored in the ROM or Flash memory devices will retain its data even if the power is removed to the
device. Manufacturers of Flash device usually specify a period of time (in the order of ten years) for data
retention.
Definition
of power states:
Main Power:
Power available when the unit is turned on.
Aux or Standby power:
Power available when the unit is in
off
state when the power supply is connected to
an active AC outlet.
Battery Power:
Power from a coin battery present in the Thin Client systems.
The table below lists the available memory devices and their types per the models. Please note that the Thin
Client systems do not use traditional hard drives with moving parts. Instead, they use
flash
memory devices
with an IDE/ SATA front-end interface. Hence, the operating systems interface with these
flash
devices similar
to a regular IDE/ SATA hard drive. This IDE/ SATA
flash
device contains the image of the operating system. The
flash
device can only be written by an administrator. A special software tool is required to format the
flash
devices and clear the data stored in them.
