I've never used DHCP but it looks like your eth0 is up (as shown by
ifconfig, and that dhclient didn't say something like 'no such eth0').
However it looks like dhclient isn't getting a response to its query.

Can the laptop connect on any other network?  Is it the cable?  Do you
have a connect light on the NIC or on whatever the other end of the
cable goes to?

Do you know the network topography or the IP of the dhcp server?  Can
you ping it from your laptop?  Can you ping anything from your laptop?

It could be a problem with the dhcp server and not with your
laptop.  Do you also control the dhcp server?  What do its logs show.
Do they show a request from your laptop?
