Laptop won't charge while playing The Sims 3

@choidimas   First guess is are you using the proper power supply? On the bottom of the laptop there should be a tag listing the power requirements - something like 19.2V  4.3A. This should match the specs on the power supply. The sims 3 game uses a computer hard and if the power supply is weak it will drain the battery even if on charge. I think the battery in your computer is internal meaning the computer needs to be taken apart to change. It is possible the power supply is going bad (rare but they do go bad). Please post the output voltage and amps listed on the power supply.
