Here's what I've been able to find:
Your Home Theater system only has Auxiliary (RCA L/R) and Optical S/PDIF audio inputs. (

Your TV, I wasn't able to find. Re-check the model number
Your laptop has both HDMI and VGA outputs.
Ideally, your set up would look like this:
Laptop --> HDMI Out --> HDTV HDMI input --> S/PDIF Optical output --> Receiver S/PDIF Optical Input.
However, this only speculates that your HDTV has an HDMI Input and an optical S/PDIF output. Otherwise:
Laptop --> HDMI Out --> HDTV HDMI Input --> 3.5mm analog output --> 3.5mm to RCA L/R audio RCA cable --> Receiver Auxiliary audio inputs.
However, this only speculates that your HDTV has an HDMI Input and can separate and convert the digital audio from the HDMI input to the analog 3.5mm output.
Lastly:
Laptop --> HDMI Output --> HDTV HDMI Input
or
Laptop --> VGA Output --> HDTV VGA Input
and
Laptop --> Headphone/Speakers Out --> 3.5mm to RCA L/R audio RCA cable --> Receiver Auxiliary audio inputs.
The second part (VGA) assumes your HDTV has a VGA input.
