A couple of things that I have noticed.
I have floppy drive inbuilt to the tower.
When running Lubuntu the green light is constantly on (drive empty).
When I connect to the Internet, I see no information that tells me how strong is the signal.
When I use the file manager, I can see the Lubuntu folders, but my folder (MyFile_programmes) is invisable..
Happy New Year.
Ps. Running Lubuntu 12.10 from a pendrive (not persistent).
