Monday..

should not start with finding your IT support work PC dead.   Just saying.

After calling the “support line” for Dell (which happens to be mostly for software support, by the way), being transferred twice and explaining my story and troubleshooting steps 3 times, I have a new power supply on the way.
The Dell Gold Support guy said, “And we’ll send a new one out with a tech to install it, is that right?”, at least realising that I probably did not actually need help, even though we seem to have paid for the super-spectacular bells-and-whistles support plan.

Erm.  No.    You may send someone over with a nice latte, though.

The good news is that one of the workers brought in a kitten.  I love kittens.   They don’t drool too much.  🙂
