Best choices for low power consumption / high battery life


This fall I'm beginning to study master's course, and I'ld like to get a laptop to use while commuting, cause my new school is about 1.5 hours away from my home.

The most important points for me are, low power consumption, size & weight, a low profile generic graphics card which will work with any OS I throw at it (including weird linux distros). I will not be gaming at all with this laptop, except the occasional online spades if I setup an XP.

So, as for the CPU, I think a low spec Pentium M is what I want. But I'ld like to know if previous pentiums are worse or better than a centrino. I believe even a pentium II @ 400Mhz will be enough for me.

also I'ld like to know how Pentium M compares to PPC laptops in terms of power consumption. a mac power book with a G3 will also prove quite interesting for me, especially after the price drop after apple announced the crossover to intel processors. I'ld like to hear from people who have experiences with mac powerbooks if possible.

thanks !

  1. Nowadays we can buy laptops under £500 - all seem to be using the Celeron M 1.4Ghz CPU. Though a Celeron the spec is much better than it used to be.

    I bought a Dell Inspiron 1300 and am very pleased with it.
    (I'm not pushing Dell, there are many manufacturers offering similar specs and prices)
    This particular laptop has a 15.4" wide screen so it's not small and weighs about 6lbs.
    The performance for the simple (ie not gaming) tasks is fine, I rarely notice it lagging and get 2 -3 hours battery life.

    Consider the Celeron M - it could be much cheaper than a Pentium M and you may not need the extra power.
  2. the IBM Leveno's report battery support from 4 to 5.5 hours.Their hardware isnt on the bleeding edge,thats one reason for prolonged life.
