The thin and light HP ProBook 5310m offers business-class features and performance, as well as the ability to get to a browser or Outlook without booting up the operating system. However, some questionable design choices smear (at times literally) the otherwise nicely built system.
The HP ProBook 5310m is a thin and light notebook with business-class
features and performance that sometimes trips up because of design choices that
mar the otherwise nicely built system.
The small, smeary trackpad-the first I've used that lacks an oleophobic
(skin oil-repelling) coating-and squared-off key caps made mousing and rapid
touch typing an unsatisfactory experience. Not affecting performance but a
constant source of annoyance was the smudge-loving glossy plastic interior
surfaces and exterior anodized aluminum case.

I tested the $899 model with an Intel Core 2 Duo SP9300 processor, 2GB of DDR3
memory and a 320GB 7,200-rpm SATA hard drive. An Advanced Micro Devices
processor option is available.
The system, which was released in October, also can be outfitted with an
ultra-low-voltage Intel Celeron processor. The Celeron should increase battery
life by several hours. There will also be a decrease in performance, although
this configuration would be more than adequate for e-mail, word processing and
My test unit came prebuilt with Windows 7 Professional and myriad standard
add-on software packages from Hewlett-Packard, including Protect Tools,
Advisor, Biz Solutions and Printing, along with a trial version of McAfee
Using the FutureMark PCmark Vantage tool (using the PCMark Suite test), the
ProBook 5310m scored a respectable 4,100 when run on the system with all the
aforementioned preloaded packages. The system is intended for modest-size
organizations that have small IT departments or consultant-only IT support. In
these cases, preloaded software often stays on the system, so I benchmarked
only with the preloaded software. (A system without the software would almost
certainly perform faster.)
The ProBook 5310m incorporates touchpad gestures, a feature already found in
HP consumer notebooks. Gestures are disabled by default but are easy to enable,
and allow for zooming, rotating and movement of on-screen images.
HP also has equipped the ProBook 5310m with two quick keys that enable preboot
access to a Web browser and the Microsoft Outlook mail client. During tests, I
configured the Outlook quick access function to synchronize my mail every 15
minutes. When the ProBook was turned off, accessing my mail by pressing the
button took about 5 seconds. Web access was available in a similar
The ProBook 5310m is well-equipped to keep wireless road warriors connected.
The system can be configured with either Intel or Broadcom 802.11a/b/g/n, as
well as optional EV-DO/HSPA mobile broadband wireless access. The system also
supports Bluetooth 2.1 connectivity.
The ProBook isn't much to look at, however. Compared with the premium
display on a MacBook Pro 13-inch system or other PC-based thin and light
systems, including Lenovo's T400s, the ProBook 5310m is dull and flat. For
business applications, however, the screen will suffice.
As with other thin and light (less than 4 pounds) notebooks, the ProBook
does not have an on-board optical drive. There is, however, a full complement
of external connectors and optional docking stations that enable the ProBook
5310m to provide all the functionality of larger notebook systems.
The ProBook 5310m has three USB 2.0
ports, one of which is powered, and a DisplayPort with an optional dongle to convert
to VGA. It also has the usual network, headphone/mic and power connectors, as
well as a Secure Digital slot.
With the ProBook's dropped-hinge design, all ports and connectors are placed
along the side of the system. This makes for some inconvenient connections (the
wired Ethernet port is far forward, on the left side). In addition, the
longer-life, six-cell 62WHr lithium-ion battery increases the depth of the
system. (A four-cell battery is also available.)
HP just keeps pace with other notebook makers when it comes to design
choices in the main user input area-the keyboard and touchpad.
During normal use in tests, the ProBook 5310m developed warm, but not
uncomfortably hot, areas near the wrist rest area. The recessed touchpad did a
good job of rejecting stray palm inputs.
It seems like HP has mimicked Apple in adopting a Chicklet style of
squared-off key caps, with a shallow and unpleasant key press depth. Most keys
on the full-pitch keyboard were effectively placed for accurate typing, but the
short space bar was easy to miss during rapid typing.
