NEC Scores a Battery-Life Breakthrough - Page 2


It Keeps Going …

The DayLite is powered by a removable, three-cell lithium-ion battery and an internal, nine-cell lithium-polymer battery. In tests using Ziff Davis Media Inc.s BatteryMark 4.0 benchmark, the duo yielded more than 7.5 hours of life between charges with the backlight switched off. With the backlight engaged, the DayLite lasted more than 4 hours—an impressive figure when compared with the 2.5 hours of life weve come to expect from comparably sized ultraportables.

The DayLite features a 10.4-inch reflective TFT (thin-film-transistor) display with a maximum resolution of 1,024 by 768 pixels. The reflective display is similar to those of Compaq Computer Corp.s iPaq 3600-series and Hewlett-Packard Co.s Jornada 560-series Pocket PC handhelds.

The DayLite is built with an integrated NIC and 56K-bps modem, a 20GB hard drive, one PCMCIA slot, two USB (Universal Serial Bus) ports, an external VGA port, an IrDA port, and standard audio ports. External USB CD-ROM and floppy drives ship with the DayLite (neither drive type is built into the unit). The notebook measures 10.4 by 8.3 by 1.3 inches and weighs 3.3 pounds—size and heft typical of ultralight notebooks.

The DayLites keyboard is large enough for extended use, but the feel and action of the keys are nothing to write home about. We suggest that NEC sit down with one of IBMs ultralights for inspiration.

We tested the DayLite in a 192MB configuration, using Ziff Davis Medias Business Winstone 2001 benchmark, which measures performance on common office productivity applications. The DayLite turned in a score of 11.7—well below the marks of other lightweight notebooks. However, Transmeta officials contend that benchmarks such as Winstone do not fairly measure the performance of its Crusoe chips.

Without entering that argument, we can say that we could multitask with media files, productivity applications and file search operations without experiencing poor performance.
