This happens on a desktop systems too, for example here: 
ubuntu 13.10

uname -a
Linux nick-desktop 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 07:38:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

lspci | grep -i ethern
00:19.0 Ethernet controller: Intel Corporation 82566DC-2 Gigabit Network Connection (rev 02)

after resume, network manager comes with "network disabled" and if you
enable it, nothing happens. However doing dhclient eth0 setup the
interface properly.

Also: issuing sudo killall NetworkManager - brought back its
functionality, so that may be used as a workaround for now.
