So, I have used Time Machine (which comes with the mac) to back the macair laptop up on my iMac, and copied all documents, photos and videos onto a small (in size not capacity) WD hard drive, and just to be sure I am now uploading as much as possible to my Virgin Media account - that is the frustrating one because it is very slow over our wireless network.
I had a conversation on facebook about best back up plans - a couple of people suggested CCC: Carbon Copy Cloner, which apparently is really good as it copies everything to a hard drive and you can just reinstall it to your machine when you need to. I'm not sure what difference there is between CCC and Time Machine, but have decided that the main thing that I care about are files so am not too bothered if Time Machine doesn't reinstall everything. I could see it as a way of clearing out the laptop a little.
I can remember most of my passwords - I took a screen shot of all the web login names and passwords that I will delete. I also need to copy and delete the saved passwords for email accounts etc. And the emails?
Now I have to decide how much other stuff to delete from my laptop before it is collected to be assessed by the insurer-nominated fixers.
I will probably delete all my documents and images and downloads, and passwords, just to be on the safe side. Then curse when all they do is replace the screen and send the laptop back intact.
This is what the screen looked like at first, with the little black hole:
And now it's more of a strange dangling spider of an ink-blot that takes over too much of the screen:
So, heart in mouth, surrendering laptop to the courier on Monday.
