The so-called $100 laptop project is working to boost education for children in the developing world.
The rugged, energy efficient laptops have been designed to be used in remote and environmentally challenging areas.
They are currently being tested around the world, including at the LEA primary school, Galadima, on the outskirts of Abuja, Nigeria.
