In ePO 4.5, EEPC 6.0 policy=>product settings=>Log on tab=> make sure that box " enable accessibility" is checked.
But according to help:
Enable Accessibility This option is highly helpful to visually impaired users. If selected, the system gives a beep as a signal when the user moves the cursor from one field to the next.
I'm sure that OP does not want that function, but rather operational sound device once OS is running, not in pre-boot.
Thanks for the suggestion but as mentioned above, that option should have no bearing. My case was opened yesterday and escalated to Tier III yesterday. I'll keep ya'll posted on their findings.
I am in the process of encrypting another E6500 running Win7 x64...don't expect to experience same issue as all my Win7 x86/x64 tests have resulted in flawless EEPC tests.
