Fingerprint Touchscreen

An Impressive Touchscreen Offsets Disappointing Battery Life

I tested the 2.53GHz Intel Core i5-540M version, equipped with 4GB of

RAM, a 250GB Hard Drive, and an Extra Battery mounted underneath. (HP

battery) HP boasts that the machine includes desktop-class

chips, and it shows in the performance and battery life; the laptop

feels speedy, but battery life is merely adequate.

The machine scored a strong 104 in our WorldBench 6 test suite, putting

it near the front of the pack in the ultraportable category, and

applications all felt responsive during general use. The EliteBook

provides ample power for Office software, image editors, and nearly

anything a mobile pro could install.

Integrated Intel GMA HD video processing lags in the most demanding

visual tasks, such as high-end GPU-accelerated 3D applications and

games. Audiences for either category should look elsewhere, since the

EliteBook 2740p targets another niche.

Instead of 3D mastery, the EliteBook impresses with its touchscreen. In

the laptop or tablet configuration, you can poke at the screen with a

finger or the stylus. The typical features of Wacom screen technology

are here, including 255 levels of pressure sensitivity and a stylus

with an eraser end for quick changes. The tool enables precise sketches

in addition to nuanced photo edits. The stylus slips inside the case

when unused, storing it well. The EliteBook automatically senses when

the stylus tip is close to the screen to disable fingertip input, but I

occasionally still managed to click with my hands when trying to

sketch. (You can manually disable nonstylus touch input in the Control

Panel.)

Touching with fingertips feels less precise by comparison, but it's

still accurate enough to navigate through applications. Once I got used

to the screen, I often just poked at icons instead of reaching for the

trackpad. The screen supports touch from two fingers at the same time,

letting you rotate or resize photos in supported software.

Unfortunately, few real-world tools yet take advantage of multitouch,

but with this laptop, you'll be ready for their arrival.

The 1280-by-800-pixel screen presents a good range of color and

contrast, although this is one of the laptop's weaker elements. Colors

lack the full richness found in competitors, and the screen begins to

wash out in a bright room. In direct sunlight, the image crumbles,

although HP says an optional outdoor-optimized display is available for

those who need to work outside.

Basic input devices work well. Flat keys bounce back tightly, and the

trackpad always feels responsive. HP also includes an eraser-style

pointing stick, similar to what you'll find on ThinkPads. I prefer the

concave shape on those competitors, but HP's take on the pointer still

quickly whisks the cursor across the screen. Two sets of buttons--one

for each pointing device--feel a little too soft, but at least they're

individual buttons instead of a seesaw lever for each click.

HP includes few extra buttons, but that's better than a laptop with

useless clutter. Touch-sensitive buttons control volume from the

corner. Two side-mounted physical buttons activate your browser or

e-mail application. A slider switch toggles on or off the 802.11n Wi-Fi

and Bluetooth 2.1. A few extra buttons reveal themselves in tablet mode

to reorient the screen and activate Escape and other common commands.

They're all well-placed and useful.

The EliteBook 2740p includes almost every significant port: USB 2.0

(three), VGA, FireWire, a headphone/mic jack, gigabit ethernet, and

analog modem. You can expand with ExpressCard/34, and an SD slot reads

flash cards. A Webcam and mic are ready for videoconferencing and other

media capture.

In addition, the laptop's security features can lock down your data. A

fingerprint scanner and SmartCard slot can authenticate users. Bundled

software can encrypt the drive or permanently destroy old data. An

option for the LoJack service can help recover a lost laptop or destroy

its data. These touches should fit business users well.

Several aspects of the EliteBook 2740p underperform. Speaker audio

sounds loud enough for a small group to hear, but it whistles out music

with shrill tones. Battery life is passable at 3 hours, 29 minutes in

our tests, but that's not stellar for an ultraportable PC. [hp laptop battery]HP sells a

flat "battery slice" accessory for $179 that adds about three hours of

battery life, but it also adds about a quarter-inch of thickness and

over a pound of weight. HP includes a series of firmware tools that can

include a Web browser or access to your Outlook data before you boot

into Windows. These would be great additions if Windows could boot in

the background, but since you still have to run the full startup

process to do anything else, they're rarely useful.

The EliteBook 2740p feels solid as a tablet or laptop. An HP

representative said the company put a lot of effort into designing it

to be rugged, claiming it can withstand 300 pounds of pressure on the

enclosure. Hopefully it'll hold up, since HP ranks dead last in our

most recent survey evaluating how companies handle problematic

portables.

While it takes an extra battery--and added weight--for the HP EliteBook

2740p to feel complete, this Small Laptop can handle mobile work

anywhere. It's quick, and the convertible touchscreen makes it

especially versatile. That touchscreen and the unit's all-around

performance make up for the shortcomings in battery life and screen

colors.
