Do you also see the model dv6-6180us at the back/bottom of the laptop?
Does it have Windows 7 or another windows version?
Is it the same computer or a different computer that you have issue with the printer previously?
Does it let you adjust the volume at the bottom right of the computer's screen?
Do you see any volume icon / key / button on the keyboard?
If you connect headphones/headsets to the laptop, do you hear sound on the headphones/headsets?
Please reply at the box below. Thank you.
