I'm estimating with that laptop you'll probably get MAX 200 h/s mining XMR... at today's price that's about $0.39/day, and only if you're mining the full 24 hours. If you speed 8hrs at work that's $0.13 per day.
ROI would be: 15358.69 days, which is 42.07860274 years. This is assuming you go to work 365 days a year. LOL
Better solution: Buy a cheap laptop and build and ACTUAL RIG!!

With today's prices, RIO is only 4-6 months.
