Short description Details Solution
Restoring Embedded
Security causes
Credential Manager to fail. Credential Manager fails to register any
credentials after the ROM is restored to
factory settings. The HP Credential Manager for ProtectTools fails to
access the TPM if the ROM was reset to factory settings
after the Credential Manager installation.
The TPM embedded security chip can be enabled in the
BIOS Computer Setup utility, BIOS Configuration for
ProtectTools, or HP Client Manager. To enable the
TPM embedded security chip:
1. Open Computer Setup by turning on or restarting
the computer, and then pressing
F10 while the
F10 = ROM Based Setup message is displayed
in the lower-left corner of the screen.
2. Use the arrow keys to select Security > Setup
Password. Set a password.
3. Select Embedded Security Device.
4. Use the arrow keys to select Embedded Security
Device—Disable. Use the arrow keys to change
it to Embedded Security Device—Enable.
5. Select Enable > Save changes and exit.
HP is investigating resolution options for future
customer software releases.
Security Restore Identity
process loses association
with virtual token. When user restores identity, Credential
Manager can lose association with the
location of the virtual token at login
screen. Even though Credential
Manager has the virtual token registered,
user must reregister the token to restore
association. This is currently by design.
When uninstalling Credential Manager without keeping
identities, the system (server) part of the token is
destroyed, so the token cannot be used anymore for
logon, even if the client part of the token is restored
through identity restore.
HP is investigating long-term options for resolution.
