Poor Battery Life Undercuts Powerful Processors and a Blu-ray Drive

The Samsung R540 seems to target a demanding audience

, since its CPU, GPU, and all-around performance can drive powerful applications and games. But a mediocre display, a weak battery, and a stingy allocation of ports keep it from hitting the mark. If you're looking for a midrange PC, the R540 is still worth considering, but don't expect a high-end system on the cheap. compaq laptop battery

For about $950 (as of September 20, 2010), the R540 delivers some impressive specs, including a 2.4GHz Intel Core i5 450M processor, an AMD Mobility Radeon HD 5450 GPU with 1GB of RAM, 4GB of system RAM, and a 400GB hard drive. The R540 scored a respectable 107 on our WorldBench 6 benchmark test suite, and fared well in real-world performance testing. From productivity software to demanding games, it can keep up with any program.

Regrettably, you won't be able to enjoy the R540 away from an outlet for long; The laptop lasted only 2 hours, 27 minutes in our battery test--a weak showing, but not sufficiently dismal to negate the machine's virtues entirely. Acer laptop battery

The input devices feel good in a plain, understated way. The keyboard comes with a full number pad and no other extras. (I prefer this arrangement to laptops that are littered with special buttons.) Keys feel snappy enough for typing, and the matte texture beats too-stylish competitors that overlook substance in pursuit of slickness.

The touchpad sits slightly below the surface of the wrist-rest, so you can feel when you've moved off the active surface, without having to look down. Pointing feels responsive, and you get separate buttons for right- and left-clicks. In addition, you can click the entire button surface, beating competitors' see-saw designs that require you to push on the ends.

The big, 15.6-inch glossy screen doesn't quite have enough resolution, at 1366 by 768 pixels. Another drawback: The screen's contrast and saturation trail off if you reduce its brightness. Though the brightest setting may strain your eyes, colors lack commitment if you turn it down.

The adequate speakers favor high tones. Wide-ranging audio gets scrunched together, yielding extra treble and no bass. Compared to competing machines, the laptop offers average sound--but the bar for portable audio is quite low.

The combination Blu-ray player and DVD burner is the system's stand-out extra feature. Students on the prowl for a multimedia laptop might like this feature enough to overlook the average speakers and sound. CyberLink movie-playing and -creating software controls the hardware intelligently. apple laptop battery

The R540 strictly rations its ports and connections. At least it covers the crucial basics: HDMI, VGA, three USB 2.0 ports, audio-in and -out, and b/g/n Wi-Fi--but no eSATA or FireWire. The Webcam with mic can capture clips or handle videoconferencing, and a flash-memory reader lets you import pictures. But you're limited to 100Base-T Ethernet, not gigabit.

Though the R540 has the processor specs and Blu-ray drive of a multimedia powerhouse, its average-looking screen, indifferent audio, and weak battery life prevent the R540 from achieving greatness.
