* The Enhanced Outdoor-viewable Display is a 12.1-inch XGA Wide Viewing Angle Display with Digitizer
that provides enhanced viewable improvements like:
12% increase in front of screen display brightness with no loss of battery life
Up to 235% increase in contrast, resulting in better viewability, at wide viewing angles
25% less specular reflections in bright light
91% less diffuse reflections in bright light
67% more contrast in bright sunlight
NOTE:
This data is based on typical measurements by the display manufacturer. Actual measurements
may vary from panel to panel.
Memory
Standard
512-MB, 1024-MB or 2048-MB 533-MHz or 667-MHz DDR2 SDRAM; two
SODIMM slots supporting dual channel memory
Maximum
Upgradeable to 4096-MB maximum (2048-MB SODIMM in slots 1 and 2)
Dual-channel
Maximized dual-channel performance requires SODIMMs of the same size and
speed in both memory slots.
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. Above 3-GB, all memory may not be available due to system resource requirements.
Communications
Broadcom NetXtreme Gigabit PCI Express Ethernet Controller (10/100/1000 NIC)* with HP Smart Power
NIC technology
56K modem** with digital line guard
* The term "10/100/1000" or "Gigabit" Ethernet indicates compliance with IEEE standard 802.3ab for
Gigabit Ethernet, and does not connote actual operating speed of 1 Gb/s. For high-speed transmission,
connection to a Gigabit Ethernet server and network infrastructure is required.
** Designed for downloads from 56K modem compliant sources. Maximum achievable download
transmission rates currently do not reach 56 KB/s, and will vary with line conditions. Modem availability is
subject to country regulatory approval.
