Computer and ants

Anyone ever had problems having ants in your laptop? I don't know why. This is my second time already. I realized there are ants around my bedroom. Traced its track and found its ending route inside my laptop computer! Gee, the same thing happened with my old laptop too. I definitely don't have food in there for ants to go in. The funny thing is that when I moved my laptop downstairs and placed it next to my dad's, those ants still chose to go only into my laptop!!! What the heck?!?!?!
