Note: We performed the productivity benchmarks, gaming benchmarks, thermals and noise, and performance over time tests using the Best Performance mode instead of the default Balanced mode. This change makes the results more representative of the laptop’s maximum potential and brings them closer to user expectations. However, this also means that the results are only comparable with reviews containing this disclaimer, as we previously tested laptops in their default mode, which usually throttles performance to prolong battery life.
