Speaker balance in Lenovo B450 Laptop

[Buckley]

I am using Lenovo Laptop for my office work, so while working I listen to the music but from past few days what I am seeing is that only left speaker of the laptop works and not the right speaker. So am confused what can I do to get both the speakers working as I have least technical knowledge about laptop. So if anyone can guide me through with this it would be really helpful for me.

According to me what I feel is that you must have by mistakenly changed the settings in the volume control. So what you have to do is that go to the system tray which is located at the bottom right side double click on the volume control, it will open volume control settings now from here you can balance the volume.
