This system would consist of an accelerometer/orientation
tracker, a sensor for height, a small battery, some
and four CO2 cartridges. The cartridges would be affixed to
all four corners of the laptop. When falling the laptop
use the cartridges as jets to orient and slow its
fall at the

||Unless the cartridges can reorient themselves on the fly (or on the drop, as it were), they might propel your laptop harder into the ground.
||Why not add airbags?see [link]
||You forgot to mention the solenoid-controlled high pressure
valves, which will add a certain amount of bulk and mass,
requiring larger gas reservoirs ...
||We now have the technology to improve on this.
What's needed is a cage that holds the laptop. When
it senses that it is falling, the cage uses small
thrusters to hover a couple of feet above the ground,
and lowers the laptop on a cable gently to the floor,
before releasing and jetting off out of the way.
