Do you have an external monitor connected?  If so then that is likely
the problem.  Ubuntu no longer suspends on lid close with an external
monitor.  I think that is a bug but others maintain it is a feature.

Otherwise have a look to see if there is a BIOS update for your PC.
If so then that may help.
