Fujitsu's "Green" Notebooks Achieves 18Hr Life

By - Source: Tom's Hardware US | B 22 comments

It's not easy being green.

Just one day before St. Patrick's Day, Fujitsu has revealed a batch of new laptops and desktops in its proGREEN line: two ESPRIMO PCs, two LIFEBOOK notebooks and two CELSIUS workstations. All devices feature pre-installed management and Energy Star 5.0 certification. Several also sport power optimized processors such as the Intel's Core i5 and Core i7 vPro.

For starters, Fujitsu's two energy-efficient desktops, the pro GREEN ESPRIMO E9900 and P9900, use Intel's latest Core i5 vPro processor and a power supply with up to 89-percent efficiency. The motherboard is halogen-free, reducing the amount of toxic chemicals needed for production.

The company's "green" notebooks, the LIFEBOOK E780 and S710, will arrive in 14-inch and 15.6-inch Energy Star 5.0 flavors. Fujitsu claims that the notebooks are 25-percent more energy efficient than previous models, with an added energy savings achieved by using an AC adapter with 87-percent efficiency. The E780 notebook even supposedly runs on 18 hours of life using two batteries.

To round out the "green" package, the CELSIUS workstations consist of a desktop (W280) and a laptop (H700), both of which feature Nvidia graphics. Both models achieve high performance while conserving energy, taking advantage of Intel's Core i7 processors. Fujitsu said that the CELSIUS models are also energy Star certified.

Currently pricing is not available, nor did the company release detailed specs on the machines.

    I'm guessing the systems use the recently released ULV Core i7 and Core i5 processors. The efficiency is a great idea, but using two batteries to achieve 18 hours isn't what some people consider green. 9 hours alone is often more than enough for most people's needs.

    Well....thought the battery life was 18 hrs per battery from the article title.

    That's still pretty decent though. Pricing will be interesting.

    I love that 18 hours on two batteries thing. People would be plenty impressed with 9 hours on one, since standard laptop battery length is 3 or less.

    is anyone else tired of things being referred to as "GREEN"

    its not that i don't care about the environment or whatever my thing is that is has become annoying, can we not call it energy efficient, or environmentally friendly instead of putting a label on it? are we that lazy as to have to use a shorter word?

    bleh, in anycase, 18 hour battery life laptop seems interesting to me... long road trips anyone?

    I love those laptops with two batteries. The best thing in my old d800 laptop is that I can just hotswap the optical drive for an extra 2.5h battery and when it runs out hot swap another without restarting. I'm looking for a replacement and it's good to know there are options.

    My girlfriend would like it. She uses her laptop while watching tv and movies. Battery winds down quickly for her

    see, now that is intriguing a laptop that you can hot-swap batteries out of, i didn't even think about that being true for this... that's actually very useful. EVEN LONGER ROAD TRIPS.... sorry got exited...

    You got that right! I barely manage 3 on a Dell Studio XPS 16 with a 9-cell.

    Who needs optical drives these days right? I'd happily drop the disc bay in my laptop for a extra battery and use a external drive.

    Though really, I think they could have done better for those power supplies.

    I'm skeptical about 15-inch laptop actually working for 18 hours on two batteries. Unless cases pictured are not workstations, but batteries.

    Well, the Studio XPS 16 is built for performance/power, not battery life.

    I'd like to see how they incorporate two batteries into the casing of the laptop. Otherwise, there are laptops out there with over 9 hours of power per battery.

    Every laptop mfg always states the operating hours on the very mimimal power settings. Regardless of the power management, bottom line every laptop acts sleepy when in a power-mizer scheme. But if this has 18 hours on two batteries... I'd have to assume that real world use with reasonable power settings one could get 8-10 hours. That's not too bad without having to resort to a netbook.

    The e780 detailed spec sheet is online; I guess the author didn't look for it. http://sp.ts.fujitsu.com/dmsp/docs/ds-lifebook-e780.pdf

    The 18-hour battery life comes from the combination of an 83 watt-hour battery (8 cells) and a 41 watt-hour battery (four cells). That all works out to an average power consumption of about 6.9 watts, which is unusually low for a full-size laptop but within reach of modern chipsets. The 18-hour figure is based on testing with MobileMark 2007, which means the laptop is doing almost no work at all beyond just staying awake and moving small amounts of data around. The network doesn't even have to be connected. You should expect to get more like 9 to 12 hours of real-world operation, which is still very good. The machine probably weighs seven to eight pounds in this configuration, so that's something to think about.
