Yes, wondered that. It'll have to wait, Rivetess has spent 3 hours on BA site trying to make sense of our flight tomorrow. Grumpy as she is, she's running on red-line for days trying to get stuff sorted. I'd have never done it - not a bit like the old days.
I did in fact try to take the Vaio apart last night. Limited tools, but of all things, I couldn't get the DVD drive out. One screw, but it refused to pull out. Tried little clips and bits on the edge - accessed where the HD came out, but nothing would release it. I put it back and it's just useable in short burst.
Thanks again, and I'll report back when I'm ensconced back 'home'.
