Probably wouldn't make a difference. And it'd clog up the vent a tiny bit, which would lower cooling efficiency a tiny bit, which would make the CPU a tiny bit hotter, which would make the fan spin a tiny bit faster to cool a tiny bit more (yo dawg we heard you like tiny bits...).

Corom Denison lol it's just an idea since pretty much not a lot of options of self replenishment minus solar power which would require you to do the one thing that people do not like... leave your device in the sun to damage the paint work, rubber, and also screen if it's a tablet or smartphone *will turn it green*

Keith Bell I've left a lot of my devices in the sun, non have gotten damaged. In my opinion it's OK to leave a laptop in the sun, just don't leave it turned on. Maybe if they made more white laptops they could implement solar panels in the lid? Someone, quick, get on the idea and rake in all the munnies!
