A 15-inch laptop typically weighs between 4.5 to 6 pounds, or 2-2.7 kg. However, the weight can vary based on factors such as the brand, model, and materials used in the construction. Some lightweight, slim models can weigh as little as 3 pounds (1.4 kg), while more heavy-duty models with larger batteries and more powerful components can weigh up to 7 pounds (3.2 kg) or even more.
