I used to and will soon again be commuting to my office via bike and train on a daily basis. Before I got my current FW13 I had two Thinkpads (L380 and t490s) which both died of flexing after a few years. I am pretty sure this happened because I had them in my backpack and often stuffed groceries, weekend luggage etc. into it. The laptop was located in its compartment at the back of the bag and due to the other luggage it was bent outwards. The same thing would happen whenever I bend down to tie my shoes or sit on a (sportive) bike: My back bends and the laptop in the bag will follow that bend to a certain degree, depending on its flexibility. Or if I have my bag on a train, standing on the floor between my legs, and by accident I hit the back side with my foot…
Now I have been doing a lot of research on proper laptop backpacks and cases that could avoid this issue. However, I could not find a single bag that adresses this. They are all well padded and I could find one brand (Minaal) which makes backpacks where the laptop is held in a flexible construction at the middle of the backplate, so that it is even less exposed to shocks than in constructions that rely only on foam. But no solution against bending (except for Peli-Cases…)
I also ordered a laptop case that was labeled as hard-shell (Smatree Hard Shell Laptop Sleeve Case), but I could easily deform it with my hands and the Laptop was moving around in it a lot, so I decided against that.
Now I am not sure if I am too concerned with this. Do you have any recommendations on how to handle this topic? Maybe even somebody from the (mechanical) devs who could explain which impacts are critical and which aren’t?
