However, at that time I had no idea about the existence of the "S mode". I could not install on the laptop some applications that were distributed and used internally in the company and which were essential for my work.

I requested assistance from the IT department, but at that time not even they had any idea about the existence of the "S mode", so they were equally baffled why on my previous Dell laptop I could easily install any application, while on its new replacement I could not. For a couple of weeks, various IT support people from teams located on several continents had repeatedly connected remotely to my laptop every day, trying to solve the problem, but without any success.
