is 2.4 kg laptop heavy?
A 2.4 kg laptop is 5.29 pounds. Laptops of that size tend to be power-hungry, so with the power brick and both cables, figure 6 pounds easy (likely a bit more). For most people, that's fairly heavy - but for all I know, you're 6 foot 5 and built like a brick house and won't care about that weight. ;-)
