I'm needing a laptop for nuclear power simulation. Typically you would just want close to 5GHz CPU and at least 6 cores, 32GB memory, 2TB storage - that will do the trick without getting into the weeds. However, as I view BBB ratings for Dell, HP, Lenovo, MSI - you name it, they're ALL in the toilet. Since laptops aren't as self-serviceable as desktops - generally speaking - is there any brand out there that has solid customer service / after sales support if something were to happen? Does anyone have any strong recommendations for or against any certain brands?
