Natural expression

I want to tell many of my daily stories to my friends, but I feel my unnatural expression makes my friends hard to understand my stories. Here is an example. I would appreciate if anybody could help me make this paragraph sound more natural.

My laptop was broken. I dropped it from my bed, its hard drive no longer worked, but the IT said they didn't know if anything else was broken. So I had to go to a specialized store where they can better fix my laptop. It might not affect my study a lot, because I mostly use computers in the library and the computer lab. I have most of important files in my onedrive account. however, I still have to get it fixed anyway, nobody can live without laptop. I still need my laptop for my study in my room and in class.

Yesterday, I just got my laptop back. They charged me $130 and I found it very expensive because the only problem with my laptop was the hardrive. The new hardrive costs $80 but the labor costs $50, which is so expensive to me. All they did was replacing a new hardrive for the bad one. If I let the IT in my school do that, I would only pay $80 or so. I will never come back to that store again.
