She is not dead, this young lady, but merely resting her head against a USB-powered ... pillow? Yes, I appear to have that right.
By closing the laptop an air cushion blows itself up, which is connected by a valve with the fan of the computer. The computer is in the "sleep mode" and warm exhaust air is blown into the pillow. The material is coated with Latex at the inside, so the supplied warm air can be kept for a longer time. The heat supply is interrupted by opening the laptop again.
