Cpu needs 2MB cache/ thread to be 'efficient' so if your laptop i5 has less than that you need to run only one thread, avx/ avx2 also helps.
Arrandale i5 m520 3MB cache does one thread @2.9GHz 40-45h/s/thread.
Sandy bridge i7 2620m 4MB cache + avx can run two threads @3.2GHz 50-55h/s/thread.
Hashwell i5 desktop 6MB cache + avx2 three threads @4.2GHz 70-75h/s/thread.
Miner is xmr-stak-cpu
https://github.com/fireice-uk/xmr-stak-cpu/releases, use pool with low difficulty to get some shares accepted, pool.supportxmr.com:3333 is default at config file.
Profitable? Yes. Will it make you rich? No. Would I cpu mine with laptop 24/7? No.
Some gpu numbers in this thread are also really low, start with trying something else than minergate.
