If you are connecting to the ethernet port in pix directly from laptop you need a crossover cable, make sure you connect to ethernet1 port which is your inside interface.
also if you can console to the PIX and see its configuration make sure pix is configured for http and telnet, if not done so here is a short script:
http server enable
http 0.0.0.0 0.0.0.0 inside
telnet 0.0.0.0 0.0.0.0 inside
