"  Jeff Robinson has some simple advice for computer owners: &amp;quot;Treat your computer like a car and do some regular maintenance.&amp;quot; In 2006, Free Geek, the Portland, Ore., nonprofit where Robinson works, received more than 15,000 donated computers, ranging from 10-year-old lemons to sleek two-year-old laptops. &amp;quot;Sometimes I open it up, and there&amp;#039;s a hairball the size of a cat in there,&amp;quot; he says. &amp;quot;I blow in it--and suddenly it works perfectly.&amp;quot; Volunteers disassemble most of the computers, salvaging metals and recycling or safely disposing of the remainder. About a quarter of the machines are refurbished--and could have served their owners longer. To extend your computer&amp;#039;s life, keep it clean and perform basic upgrades such as increasing memory. "^^<http://www.w3.org/2001/XMLSchema#string>
