*The optional Outdoor Viewable Display is a standard 12.1-inch XGA Wide Viewing Angle Display with Digitizer that provides enhanced viewable improvements like:

z12% increase in front of screen display brightness with no loss of battery life

zUp to 235% increase in contrast, resulting in better viewability, at wide viewing angl

z25% less specular reflections in bright light

z91% less diffuse reflections in bright light

z67% 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	256-MB, 512-MB, or 1024-MB 400-MHz or 533-MHz DDR2 SDR
		two SODIMM slots
	Maximum	Upgradeable to 2048-MB maximum (1024-MB SODIMM in slots
		2)
	Dual-channel	Maximized dual-channel performance requires SODIMMs of the
		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 s
	will perform at the lower memory speed.
Communications	NetXtreme Gigabit PCI Express Ethernet Controller (10/100/1000 NIC)* with HP power dow
	technology

56K modem** with digital line guard

*The term "10/100/1000" or "Gigabit" Ethernet indicates compliance with IEEE standard 80 for Gigabit Ethernet, and does not connote actual operating speed of 1 Gb/s. For high-spee transmission, connection to a Gigabit Ethernet server and network infrastructure is required

**Designed for downloads from 56K modem compliant sources. Maximum achievable dow transmission rates currently do not reach 56 KB/s, and will vary with line conditions. Modem availability is subject to country regulatory approval.
