T400 Shuts down when plugging in monitor with VGA

My T400 shuts down instantly when I plug I my monitor (Dell WA2209). If I shut down the computer, and then try starting the computer with the monitor plugged in, the computer shuts down almost instantly after I press the power button.  In each case, I have to unplug the computer, and remove the battery, before I can try turning the computer on again.  I have installed the latest power manager, video drivers and bios. On the odd occasion, I am able to plug in my monitor without the computer shutting down.  This happens when using integrated and discrete graphics.  It worked for almost a year just fine, and just recently started doing this.  Any ideas?

 

Thanks in advance!

Hmm... Seems to have fixed it for now... I'll keep monitoring it over the next few days.  Would've never guessed that as I've never had a monitor cable fail on me!  Thanks!
