Unless you fancy buying a new laptop when it burns out then its not going to be a worthwhile exercise.

Your better off downloading core or something on your laptop and having a play with that or get yourself some GPU's and a motherboard and mine some altcoins but bitcoin is no longer viable to mine on CPU. It CAN be done but it would be a futile exercise and be a waste of your machine.

Look into miners like avalon or s9 miners if you're looking to get into mining they are the only real viable options for profit but you need to take into account a few things before going down the asic route.

1. Power cost!  You need to know what your electricity will cost before you start this is key to your ROI if your electricity is costing more than you can mine then it's not a good idea.

2. Heat... These suckers pump out a lot of heat and require good ventilation for optimal performance,  many people overlook this factor when buying and setting up.

3. Difficulty... The network is taking some rather epic jumps recently and there is much new hashrate coming online every day so you need to factor in the increase in this as this will affect your return.

Hope this helps.
