Sorry, continue my questions here:
1. If I have BartPE boot CD on hand and "authorised code of the day", what should I do when I want to decrypt and recover the data on my HDD?
2. What is the detailed steps?
A attached my HDD status here and hope any one professional can give me a hand on this! Many thanks in advance!

You should post questions in the data protection forum rather than here, but as your problems are with a HP product, you really need to discuss with HP.
In theory you could use WinTech to decrypt your old partitions, but this is a HP product, so there's not much help we can give you.
