branded memory to ensure compatibility. If you mix memory speeds, the system will perform at the lower
memory speed. Full availability of 4 GB or more of memory requires a Windows 64-bit operating system
or Linux. With Windows 32-bit operating systems, the amount of usable memory is dependent upon your
configuration, so that above 3 GB all memory may not be available due to system resource requirements.

Keyboard

The HP spill-resistant keyboard is designed using a thin layer of Mylar film under the keyboard and a
drain system that funnels fluid through a hole in the bottom of the notebook. This minimizes the risk of
damage to sensitive components underneath. The 101/102-key compatible keyboard features a full-pitch
key layout with desktop keyboard features, such as the isolated inverted-T cursor control keys, editing
keys, both left and right control and alt keys, full separate numeric keypad, and 12 function keys. US and
International key layouts are available. Other features include hotkeys for instant access to power
conservation and brightness, and 19.05 x 19.05 mm key pitch (center-to-center spacing).

HP ProtectTools is now centrally manageable with the capability to manage notebooks from a single
point. Security is management ready out of the box, in partnership with Digital Persona. New features
address requirements that customers expect from a centrally managed security solution such as user
provisioning, credential reset, and credential revocation.

HP ProtectTools provides two separate management solutions, targeted at the enterprise and the SMB:

Digital Persona Pro AD: Designed for the enterprise customer. Integrates with Active Directory and
gives IT Managers the ability to provision users, create login policies based on passwords,
biometrics or smartcards. Management features also include remote credential recovery in case the
user forgets the password, loses the smartcard or cannot use the fingerprint reader for any reason.
In addition, advanced auditing capabilities are also built in. Digital Persona Pro AD is available
now.
Digital Persona Pro Workgroup: Designed for the small business customer. Provides features similar
to the Active Directory version, but for workgroups. Workgroup activation is built into HP
ProtectTools, and activation of up to 5 seats is completely free.
