It seems that newer Dell Laptops support SGX out of the box without any update. Just check the BIOS for any SGX option. At least the Dell Precision 17 7000 Series (7710) got that option.
According to different user manuals it seems that you can turn on SGX on the following models. Source: http://pilot.search.dell.com/sgx
If you want to make sure that SGX works on these systems compile and execute the /test-sgx.c
Feel free to discuss you findings regarding newer Dell computers and SGX support here. :)
