There's nothing pulling so much power at startup that both the adapter and battery are required.

Even older MacBooks would boot with the battery disconnected (in some sort of safe mode).

Newer ones likely wait to check the battery properly.

I've not come across any laptop or Android smartphone that wouldn't power up without a battery.

However, I do not have any experience with USB-C powered laptops, those might be different seeing as they need to negotiate power first.

I had the pleasure of working on an Android smartphone that wouldn't power up without a battery. Or even with a battery, if the outside temperatures were sufficiently low to cause the battery voltage to drop below the FCC-defined limits for running the radios.

What make/model? Sounds a lot like a soldering problem somewhere. Or really poor design heh
