Hello all, i have a laptop in my car for playing mp3's and gps usage. I wanted to know if there was an easy way to make it turn on when i tirn the car on and turn it off when i turn the car off.

Right now i have the constant to momentary relay listed on this very useful page to turn the laptop on, however how can i get it to pulse the power button when i turn the car off?

thanks again!
