HP has implemented the One Step Logon feature on its 2008 and newer commercial portable
The HP ProtectTools Security Manager wizard enables various security levels to protect the
computer system and the data. The security levels that can be set are:
HP Credential Manager – Protects your Windows account
Preboot Security – Protects your computer before booting to OS.
HP Drive Encryption – Protects your computer data by encrypting the hard drive.
Along with security levels, the user can select the security login methods for authentication at
each security level. The possible login methods are: Windows password, Fingerprint and HP
When the login method is set to Windows password and all security levels are enabled, the
One Step Logon feature allows the user to enter her/his Windows password in the Preboot
BIOS and drive encryption environment, which then logs the user all the way into the
appropriate Windows account.
The complexity arises when Windows support hundreds of Input locales. A user can enter the
Windows password using an input locale that's different than the physical keyboard. e.g. The
user can select to type German using the International US keyboard layout etc.
However, at the Preboot Security level and the HP Drive Encryption level, the input localization
support is limited. The purpose of this whitepaper is to help user understand the limitations
and also to set the proper Windows password to avoid the lockout situation when the Preboot
Security Level and/or the HP Drive Encryption level is enabled.
The HP_Tools partition feature described in this document is supported by 2008
and 2009 HP business notebooks.
