A laptop should have two to four speakers (two is common) and I think that they should work unless you don't have a proper audio driver, the audio services aren't running, or you have a hardware problem with your audio.

Does your laptop have an HDMI port? Then the standard audio device may have been switched to HDMI. You can change that back to onboard audio in control panel.
