Power Consumption and Battery Life
Granted, we were working the machine 100% of the time here, so we suspect you could probably squeeze 2.5 or 3 hours out under the right conditions. Still, 4.5 hours seems more like a pipe dream, and we wouldn't honestly expect to see that from this machine under any real circumstances. The non-ULV processor isn't the most energy efficient, and 15.4 inches of LCD is a lot to light up. Still, ~2 hours should be plenty for most scenarios, and again, we keep coming back to the $499 price tag. For business users on a budget, we'd surmise that 2 hours of life is plenty for the price. Even the majority of netbooks can't survive over 3.5 hours with a charge, so the G530 really isn't that far off from its competition.
Would we have preferred it lasting longer? Sure. Would we be willing to pay $50 or so more for another half hour? Probably not. We're glad Lenovo kept the unit as-is, and for those who really will need more than 2 hours of life in one sitting, we hear those "extra batteries" can be procured with relative ease. Also, we struggled to find similar machines to compare the G530 to. Price wise, it's nearest competition is the average netbook. Specification/size wise, there are oodles of similar 15" notebooks to compare it to, but generally speaking, they all cost quite a bit more due to fancy extras, a stylish design or a discrete GPU. As you can tell, it measured up to none of our benchmark machines, but for $499, we think it had a solid showing.
