My new JanSport laptop backpack fits me great and has padding on four sides of the computer. I realized, however, that there was virtually no protection at the bottom of the laptop sleeve. Fortunately, I found a quick fix.
For this hack, you will need:
-1 chunk of foam , about .5" thick.
-Exacto knife or razor
Step 1: Gather Materials
I had a box for a nice pen from which I harvested the foam. (I use the box to hold my Sharpies now.) Just find/cut a piece about half an inch thick(1.25cm) and the same width as your laptop.
