Simply to ascertain whether you are a Vaio user looking for help or someone seeking assistance on a business-related venture. I personally don’t contribute to this forum to help commercial repairers as anyone undertaking work for gain should have the relevant manuals or inherent knowledge to undertake the work without the need to resort to a user forum.
These are my own views and are not related to the forum t&c’s.
@DaveLingard Thank you for pointing this out, I think that was a much needed comment.
I did manage to resolve this myself (without any useful input from Sony)
You might find it useful to know that the back plastic panel is removable, you just need to take out the screws that hold it in. From here it is quite easy to access the vents and other components. The front plastic cover around the screen can also be removed once these screws have been taken out.
