Ditch the laptop and take an iPad (reduce weight by removing unnecessary apps beforehand).
Better still, just print out a picture of an iPad (on low GSM paper) and take that. If you get the picture from an Apple ad or fanboi site the amount of hot air will keep it (and the aforementioned balloons) afloat.
The mention of smart phones raises issues, especially as most use a removable memory card, so compounding your original problem (albeit it in micro form). If you do take one, delete all apps, contacts (except your mum) and anything else that makes it smart (knowledge is weight).
You can delete the translator app. In the womb you developed an innate ability to understand anything your mum says (mine spoke Louisiana Creole and later Persian Aramaic for several years on a whim and I was fine with it). Of course you lost that ability between ages 3 and 5 and again during your teens, but you will be good now.
