Hi Christopher, thanks for the reply. I don't have easy access to a voltmeter, 
but have tried another known working ThinkPad charger (same model) with no 
results. (My other half also has a ThinkPad.)

I'm not sure why that would explain why it doesn't turn on when the batteries 
are inserted and the charger isn't. The batteries were fully charged when it 
was shut down and would normally give over 3 hours run-time.
