HP recommends Windows 7.
ProBook 4720s Notebook PC
10.
Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.
11.
Maximum memory capacities assume Windows 64-bit operating systems or Linux. With Windows 32-bit operating systems, memory above 3 GB may not all be available
due to system resource requirements.
12.
For hard drives, GB = 1 billion bytes. Up to 8 GB (for XP), 10 GB (for Vista), or 15 GB (for Windows 7) of system disk is reserved for the system recovery software.
13.
As Blu-Ray is a new format containing new technologies, certain disc, digital connection, compatibility and/or performance issues may arise, and do not constitute defects
in the product. Flawless playback on all systems is not guaranteed. HD-DVD movies cannot be played on this device. Models with discrete graphics support Blu-Ray with
either Windows 7, Windows Vista, or Windows XP.
14.
Double-layer discs can store more data than single-layer discs. However, double-layer discs burned with this drive may not be compatible with many existing single-layer
DVD drives and players. LightScribe media required and sold separately. LightScribe creates a monochrome image. Note that DVD-RAM cannot read or write to
2.6 GB single-sided/5.2 GB double-sided—version 1.0 media. Don’t copy copyright-protected materials.
15.
Internet access required.
16.
Sold separately or purchased as an optional feature.
17.
Wireless access point and Internet service are required and are not included. Availability of public wireless access points limited.
18.
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/sec. For high-speed transmission, connection to a Gigabit Ethernet server and network infrastructure is required.
19.
Requires initial user setup.
20.

for more information.

Windows XP Professional is preinstalled on this system and includes end user rights and media for Windows 7 Professional. You may only use one version at a time. You
must back up all data (files, photos, etc.) before uninstalling and installing operating systems to avoid loss of your data.
8.
Dual/Quad Core is designed to improve performance of certain software products. Not all customers or software applications will necessarily benefit from use of this
technology. 64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers, and applications enabled
for Intel 64 architecture. Processors will not operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance will vary depending on your
hardware and software configurations. Intel’s numbering is not a measurement of higher performance.

Power calculations and cost calculations are estimates. Results will vary based on variables, which include information provided by the user, time the PC is in different
power states (on, standby, hibernate, off), time the PC is on battery or AC, hardware configuration, variable electricity rates, and utilities provider. HP advises customers to
use information reported by HP Power Assistant for reference only and to validate the impact in their environment. Environmental calculations were based on U.S. EPA
eGrid 2007 data found at
www.epa.gov/egrid/
. Regional results will vary.
