When you want to carry your heavy laptop

For those who didn’t know if we can remove the battery of laptop, we can remove it and can reduce its weight. This is if we can use it like a computer (i.e. with electric cable always plugged in laptop). Just find how you can remove the battery and reduce the weight of your bag. I could do it for my hp laptop. Now it is easy for me to carry my laptop every weekend to Mumbai. Yippee!
