Thank you for your advice. I checked that the RAM was firmly installed as having upgraded desktop RAM and been shocked at the force necessary to bed it, I was unsure of the notebook's ease of insertion. It was OK however and the solution for me has been to disable Hibernate and re establish it as advised by Shawn.
Thank you both once more. You have been of great help.
