£350 Acer Aspire Timeline 5810T Core 2 Solo ULV SU3500 1.4GHz / 4GB / 320GB

There's no time like the present for making important changes to help the environment.

With this in mind, Acer's beautifully crafted Timeline Series of energy-conscious notebooks, proudly feature lower power consumption for long-lasting, energy-efficient portability.

Charge up once and go all-out from morning till night! The Acer PowerSmart key provides one-touch system-wide energy conservation, delivering 9-plus hours of on-the-go notebook action.

What's more, Acer ComfyCool technology cools down the processor and the notebook case -- even when running for a full day the notebook remains cool in your hands or on your lap.

The TimeLine features an ultra thin and light design, ideal for portability. At just 1" thin, rising 5mm at its thickest, the TimeLine series fits neatly into your hand or in a bag.

And at just 2.4Kg for the 15.6" Aspire 5810T, it is light weight for pain free all day mobility.

The Acer Aspire Timeline Series boasts real energy savings whether on the road or plugged in at your desk.

While on the go, up to 40 percent more power is saved as compared to typical notebooks; and with the Acer PowerSmart adapter, savings of as much as 66 percent can be realized while your notebook is plugged in and in sleep mode.

Buy it from Play for £350. It comes with a Core 2 Solo ULV SU3500, 4GB DDR memory, 320GB RAM, a 15.6-inch screen, Windows Vista Home Premium and more.
