Performance and Benchmarks

The LifeBook T580 won’t win any awards for processing power, and doesn’t fare well against recent tablets in our benchmark tests. But in fairness, those are larger machines more suited for performance. We’re confident that the T580 would compare well against the Lenovo S10-3T “netvertible,” but we can’t be sure since we did not review that product.

The T580 is more than capable of handling day-to -day tasks with its core I3 processor. Business users won’t have trouble running several Office applications at the same time while clicking through multiple browser tabs, and they should be able to log into webcasts and video conferences without any major hiccups.

The T580 also handles streaming standard definition video well, but HD pushes the limits of the machine, which could present issues for professionals come presentation time.

Intensive gaming is also out of the question, and not only because business users should shy away from wasting company time!

We should note however, that one advantage of Fujitsu business machines is that they are easily upgradeable and highly customizable before purchase. While our review unit had an Intel Core I3 processor, Fujitsu offers a Core I5 option.

Fujitstu claims the three-cell battery on our review unit provides up to 3 hours and 25 minutes of juice. We came close to that mark with moderate use on a balanced power setting with Wi-Fi on and the screen brightness set to 70%. However, we only managed 2 hours and fifteen minutes before the T580 went to sleep with constant video streaming and the same settings. As with the processor, Fujitsu offers a better option, this time in the form of a six-cell unit (5800 mAh), which the company claims provides up to six hours and fifty minutes of power.

Heat and Noise

Heat and noise are nonfactors with the T580, and the review unit stayed cool through most use cases. We finally got the fan to kick on when running the benchmarks, and only then did it produce a tiny whirl. Just like any good business machine, the fan noise won’t disrupt a meeting or presentation, and the T580 won’t burn any thighs should it rest on a lap.

For serious road warriors and business pros who want both inking and a full keyboard, the Fujitsu LifeBook T580 is the only small form factor convertible on the market. Luckily, it’s also a solid option.

Fujitsu LifeBook T580True, both Dell and Lenovo offer netbook-sized convertibles, but neither offers the security, stability or upgradeability of Fujitsu’s LifeBook series.

We have a few gripes with the device, including the dearth of USB ports, underwhelming battery and performance, to say nothing of the price. But the T580 provides a great overall inking experience, and its build quality is apparent after spending only a few minutes with it. Also, Fujitsu allows for a great deal of customization when ordering, giving customers the option of a more powerful processor, which we reccomend.

In the coming months, the T580 will have market competition in the form of the mobile Windows 7 slates, sliders, and transformers announced at CES. But for right now, this LifeBook is the number one mobile convertible for professionals… and not just by default.


  • Fine inking and display
  • Decent keyboard
  • Good security features
  • Easily upgradeable


  • Only two USB ports
  • Default pen pressure sensitivity too low
  • Design heavy on plastic, too bulky
  • Battery life only adequate
