Approximately week or more ago my external VGA port stopped working - Catalyst control center detects new monitor attached, but there is no output signal (at least monitor says so). Monitor itself & cable is tested and works fine.
It seems that either it is hardware defect or recent windows update caused it. I am not sure how to test it. (Radeon drivers are dated back in 2009)

how about a downgrade of the bios?
Also, try to switch to vga + internal in your bios under display. Boot the laptop with the internal LCD closed, does anything come up on the external LCD?
