Nothing.

And those little solar mats are mediocre at best. They just don't work very well. They take forever to charge and require strong direct sunlight. But hey, if you want to use them, go ahead. They are still better than having them built into the device.
- ant6n 6y agoSo it appears modern smartphones have a power consumption of about a Watt (see cousin post). Assuming a transflective display, that laptop could use a similar amount of power. Assuming a 20cm x 30cm charge area and 1000Watt/m2, you need to only capture 1.7% of the energy of the directly incident sunlight [1]. Or assuming your panel has 10% effiency, you need to get 17% of direct sun light light onto the surface. Thats a fair allowance for clouds and weird angles and whatnot. [1] 1W / (20cm*30cm*1000 W/m^2)*
