The laptop is an Acer Aspire 5720.

And Yes I do have access to another LINUX machine (not Ubutnu but 
openSuse) but that is at home and I am not at the moment! if the problem 
occurs when I am at home I will try ssh'ing into the laptop via suse, in 
the mean time I just trying to find out what is happening as it is *not* 
necessarily re-produceable 'on demand' only happens 1 in 5 times the lid 
is closed (approx).

Hope this helps
