Noise coming from the laptop could be from a variety of different sources. To determine if the sound is coming from the game itself or from the speakers, press the Fn and F2 buttons at the same time to mute the speakers. If the noise stops, there could be a speaker issue or just an unfamiliar noise in the game. If the noise persists, try to pinpoint a location of the noise by listening if it is louder near any of the vent locations of the laptop. One of the most common causes of the laptop making noise originates from dust accumulating near these vents. Compressed air in a can or a household vacuum can be used to clean the vent area without opening up the laptop. If the noise is not resolved, the fan inside the laptop may need to be replaced. If replacing the fan is not the solution, further support may be needed in replacing other components of the laptop. If there are other issues associated with the laptop, try troubleshooting where those issues are originating. By fixing the other issues accordingly, it is possible to eliminate the noise issue as well. It is normal for some parts of the laptop to make noise, and it does not mean that all noises require a replacement of parts. A quiet whistle or soft humming sound can be expected from the hard drive. Remember to consider any conflicts with the warranty of the laptop before attempting to disassemble the device. Also, make sure to use proper safety precautions at all times. By using the following troubleshooting page link, causes of a noise issue can be resolved:
