It should be noted that you don't even have a cheap dedicated  GPU but just the Intel graphics processor integrated into the CPU. It won't give you much in the way of processing power. Even if you had bought a good notebook with switchable graphics it would be a bad idea to mine with it, since notebooks really aren't build to run under full load for extended periods. You will run into overheating problems and ruin your laptop if you try to let it run 24/7.
