Q: What does three short, three long, three short beeps mean (opposite sequence to http://support.apple.com/en-us/HT202768)

What does three short, three long, three short beeps mean?

 

This is the opposite sequence to that mentioned at http://support.apple.com/en-us/HT202768.

 

Computer was working fine until a move, then no start up screen, only beeps.

 

I've read elsewhere about RAM etc, and tried to select d to start a hardware test before, during and after start up, but no response, although I am using a windows keyboard.

 

thanks for any ideas,
