Doing mining would probably shorten laptop lifetime (or melt it down), so it's really not a tool to do mining with.
Next mining bitcoins with such (slow) hash rate is not a good idea... You might try and mine some other coins and keep them until their value rises or trade them for bitcoins or just sell them.
If you want to mine bitcoins - the best way is to rent cloud mining at
CEX. It costs about $65 (0.07 BTC per 1 GHs) in today exchange rate for 1 GH/s and that's really cheap and the best part is that you can sell your rented equipment any time and get some (or even more money) for it. So you got nothing to loose. The only problem is that you need to have bitcoins since buying mining power is done only using bitcoins
Buying dedicated mining equipment is really expensive, devices are often poorly built and many people wait for months to get them delivered etc... so it's IMO lot of risk to put your money into since if the BitCoin bubble bursts - that equipment is totally useless...
hope it helps...
