* Memory speed is processor dependent.
NOTE: Due to the non-industry standard nature of some third-party memory modules, we recommend HP
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 Windows Vista Business 64-bit 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).
