Dell Inspiron troubleshooting/advice?

Hey, I need some expert eyes here. What’s a fair price for a Dell Inspiron with these specs:
18.4" screen
i5 2.27/2.53 GHz
6GB DDR3
500GB WD BLUE SSD + 500GB HDD
Nvidia GeForce GT 330M (1GB DDR3+2GB shared memory)
Optical drive
web Camera 1200 x800
Card reader, VGA, HDMI, optical audio out, headphone jack, built-in mic, 3x USB 2.0
Harman Kardon speakers
Hybrid digital-analog TV tuner
original Windows 10

Battery lasts about 30-60 mins, boots in roughly 20 seconds; works perfectly, just shows some signs of wear.

Thanks.
