Notebook Suspense Problem

[Christoph Georgi]

Hi,

after installing Ubuntu on my notebook again (in order to get rid of 
Windows) I encouter a new problem that hasn't occured yet:

Every time I close the lid of my notebook it seems that Ubuntu goes into 
suspense or sleep mode but can not recover as I open the lid, i.e. I 
have to turn my computer off (using the power button!).

The odd thing is, that I hadn't had that problem before..?!

Thanks in advance for any help.
