In order to be profitable you will need to either pull the laptops out of the garbage or get a really good deal. Most of the time, the profit margin is too thin to be viable. I used to get laptops for $10 to $20 at Goodwill, but they would need $50 to $100 worth of parts and only sell for $100 to $200. After labor, parts, etc. You would be lucky to break even. I would spend more time looking for some good repairable laptops at a decent price, then actually selling them. Maybe if I had a store and people brought me laptops to buy, it could be profitable.. But its extremely thin margins.
