3.31 BIOS SETUP 3 Tests and Diagnostics (a) TPM This setting enables or disables the computer's Trusted Platform Module (TPM) security controller. Disabled Disable Trusted Platform Module security(default) Enabled Trusted Platform Module security. (b) Clear TPM Owner This setting is used to erase the data stored as part of the Trusted Platform Module, as would be required, for example, when disposing of the computer or when the owner of the computer changes. Once this operation is carried out, the Trusted Platform Module configuration settings are erased such that any encrypted data can no longer be decrypted and the files can no longer be read. In view of this you must ensure that you backup or delete the data as necessary before carrying out this operation. The procedure to follow is as detailed below: 1. Move the cursor to the Clear TPM Owner setting and press either the Space key or BACK SPACE key. 2. A message is displayed at which you should press the Y, E, S, and ENTER keys in sequence - the Trusted Platform Module information will then be erased. 3. The Trusted Platform Module setting will then change from being Enable to Disabled and the setting no longer displayed. Note: When using TPM, please refer to the Infineon TPM Installation Guide from the C:\TOSAPINS\Infineon TPM Installation Guide and ensure that the user reads as it contains usage information and notes on using TPM security. 12. Display This group of options configures the computer's display. (a) Power On Display This option is used to select the display when booting up. Auto-Selected Selects an external monitor if one is connected. Otherwise it selects the internal LCD. (Default) LCD+AnalogRGB Selects both the internal LCD and the external monitor for simultaneous display. PORTEGE R500 Maintenance Manual (960-634) [CONFIDENTIAL] 3-95
