EPA Energy Star Laptops

The Bottom Line: With an ultra-low-voltage CPU, the Dell Inspiron 1470-3282 runs longer but slower than competing laptops. We're not thrilled with the performance hit, but we still found lots to like about this well-designed, 14-inch laptop.

Specs: Intel Core 2 Duo (1.3 GHz), 4 GB DDR3 SDRAM, 320 GB, Microsoft Windows 7 Home Premium 64-bit Edition, 4.6 lbs, 14 in TFT active matrix, EPA Energy Star

The Bottom Line: HP's new Envy 15 packs high-powered components into a svelte 15-inch body. The result is an upscale status symbol that still shows a few first-generation rough edges.

Specs: Intel Core i7 (1.6 GHz), 6 GB DDR3 SDRAM, 500 GB, Microsoft Windows 7 Home Premium, 5.1 lbs, 15.6 in TFT active matrix, EPA Energy Star

The Bottom Line: The design and portability of the Asus UL50AG make it one of the slickest 15.6-inch DVD-drive-equipped laptops we've seen, but an ultralow-voltage processor compromises its computing power.

Specs: Intel Core 2 Duo (1.3 GHz), 4 GB DDR2 SDRAM, 500 GB, Microsoft Windows 7 Home Premium 64-bit Edition, 5.1 lbs, 15.6 in TFT active matrix, EPA Energy Star

The Bottom Line: The Dell Inspiron i1545-4374PBU is a good, if basic, laptop with a strong price-to-performance ratio.

Specs: Intel Pentium (2.16 GHz), 4 GB DDR2 SDRAM, 320 GB, Microsoft Windows 7 Home Premium 64-bit Edition, 5.7 lbs, 15.6 in TFT active matrix, EPA Energy Star

The Bottom Line: Sony's bold experiment--a high-end luxury system with essentially Netbook components--makes an enviable coffee shop conversation piece, but one that includes some serious sticker shock.

Specs: Intel Atom (2 GHz), 2 GB DDR2 SDRAM, 128 GB, Microsoft Windows 7 Home Premium, 1.6 lbs, 11.1 in TFT active matrix, EPA Energy Star, RoHS

The Bottom Line: Lenovo's Windows 7 upgrade to the ThinkPad SL500 keeps the price affordable, and features a consumer-friendly 16:9 display.

Specs: Intel Core 2 Duo (2.53 GHz), 3072 MB DDR3 SDRAM, 320 GB, Microsoft Windows 7 Home Premium, 5.3 lbs, 15.6 in TFT active matrix, EPA Energy Star, RoHS

The Bottom Line: Attempting to create a premium-priced version of a Netbook, Sony has added an HD display to the Vaio W. It's an attractive step-up package, but the internal components are the same as are in cheaper models.

Specs: Intel Atom (1.66 GHz), 1 GB DDR2 SDRAM, 160 GB, Microsoft Windows XP Home Edition, 2.6 lbs, 10.1 in TFT active matrix, EPA Energy Star, RoHS

The Bottom Line: The stylish design and high-end feel of the Toshiba U505-S2940 don't make up for mediocre ergonomics and performance that can be had for less in other laptops.

Specs: Intel Core 2 Duo (2.1 GHz), 4 GB DDR2 SDRAM, 320 GB, Microsoft Windows Vista Home Premium 64-bit Edition, 4.9 lbs, 13.3 in TFT active matrix, EPA Energy Star, EPEAT Gold, RoHS

The Bottom Line: If you're searching for a great-looking thin-and-light laptop at a good price, the Lenovo IdeaPad U350 bridges the gap between personal and professional and is worth checking out. But its design is more successful than its horsepower.

Specs: Intel Pentium (1.3 GHz), 3 GB DDR3 SDRAM, 250 GB, Microsoft Windows Vista Home Premium, 3.5 lbs, 13.3 in TFT active matrix, RoHS, EPA Energy Star

The Bottom Line: It may not inspire, but for less than $600, the Gateway NV5807u is a great value as an all-around 15-inch laptop.

Specs: Intel Core 2 Duo (2.1 GHz), 4 GB DDR2 SDRAM, 320 GB, Microsoft Windows Vista Home Premium 64-bit Edition, 6 lbs, 15.6 in TFT active matrix, EPA Energy Star
