Hibernate takes all the current state and copies it to swap.  Thus you 
need a large swap to handle this.  I always create my swap twice my 
memory size.  I tend to have 4 workspaces running with:  4 copies of 
Thunderbird, 6 open LIbreoffice docs, 20 Firefox windows with lots of 
tabs, a few gedits, a few Natulises, and sundry others.  I really don't 
like to boot unless I have to.  Suspend and Hibernate are my friends.  
When hibernate works on this Lenovo; a known problem.
