I've had the brightness cranked to max, it shows zero signs of life. No high-pitched noise, sounds of a CRT starting, nothing. That's normal behavior however if they don't have a proper MDA signal coming in, and my MDA card is in unknown condition, so my bets are more on that my MDA card is bad or my Deskpro 286 not initializing it than the monitor being COMPLETELY dead.
As for the laptop - unfortunately, it's weird. It did not come with the battery, and I believe that the battery was an external pack that clamped onto the back somewhere. There is no internal battery bay, but it has battery status LEDs on the front. I know some of the other early Nan-Tans did this too. I can't find an obvious battery connector either, so my only guess is that it connected direct to the main power connector, which is a mini-din similar to PS/2 or mac serial. I could definitely find the cable for it, but it would be getting the right pinout that would be a challenge.
