how to fix my laptop sound..the sound broken on the left side

If you mean that sound comes out on the right speaker and none on the left, I see two possibilities.
First, bring up volume control and make sure that it's centered, with the same volume on the left and the right.
If it is, plug in headphones. If you get the left with the headphones, the machine needs to be fixed. Physically.
