Just a head's up to other using this form factor. We just got our latest batch of M70q's with Core Ultra 5 processors. They ship with 90W power bricks, as does the 24" TIO monitor. When powering up the computer itself when NOT mounted to the monitor, all is well. When powering it up when mounted to the monitor there is a "Power supply is of insufficient voltage" warning message on a cold start. This works fine using some as-yet-installed i5 1400 units we got ready last week, so the new Core Ultra 5 versions must draw more power and Lenovo hasn't caught on yet.

We tested the unit giving the power warning using 3 different 90W supplies, and proceeded onto the other 2 Core Ultra 5 units waiting for setup - all of them give the warning on cold start.

We went around a bit with Lenovo, but just ended up in a loop, so we ordered 130W supplies to keep our delivery schedule intact, figuring we would fight it out later. I have a call into the Disti as well, but it's not really their fault - maybe they'll appreciate a warning though.
