BTW This is my first instructable,.. Make a cool LED lights on back of your laptop. You need to connect LEDs parallel to your speakers, leds will blink with rhythm of music yours playing.. Be careful that about your LCD, a little pressure may broke it..
Step 1: Opening Lid of Your Laptop..
First of all you must open lid of your laptop to see a situation inside, Be careful.....You must make sure that you have speakers bottom of your LCD if you want this to work, if you dont, you must take wires trough your laptop..,

Step 4: Drill Holes.
Drill two holes for LEDs and put leds inside..
Step 5: Secure Your LEDs
