Backing up the TPM Key

The information required to decrypt the TPM key can be backed up in USB memory, taking into account cases such as when the TPM chip needs to be replaced.

1. Insert a USB memory device into the USB port of the machine.

2. Tap [Utility] - [Administrator Settings] - [Security Settings] - [TPM Setting] - [TPM Key Backup].

3. Tap [Restoration Password], then enter the password to decrypt the TPM key (using between 12 and 64 ASCII characters).

4. Tap [Start].

   The TPM key is saved in USB memory.

   Do not remove the USB memory device during the backup process.
