When the display goes blank, does the power light start flashing to 
indicate the laptop has gone to sleep?

Try turning off power saving in the settings. When I was testing, the 
power saving automatically turned off when I plugged in an external 
display and turned on again when I unplugged it, but perhaps this isn't 
working on your laptop?
