It was during my one-on-one meeting with one of my engineers when the external screen went black. Then I realised I lost the audio too. I was already blaming technology, clicking various things on my laptop, when I spotted that more things were off. It was a power blackout in my home office. Obviously my laptop was still working thanks to battery, so it took me a while to realise that nothing else works. Work from home and power outage. What a combo!
