Hello, my concern is that of incoming voltage. Primarily on a laptop system but i suppose aside from apc it would be cool for desktops too, but mostly laptops. I use an APC and its utility actually returns line voltage as a parameter. I also know of utilities that will return battery status and voltage. So as a tech it would be nice to know if there are problems with the laptop ac converter. I know, why not just switch out the power adapter to check, right? What if I don't have a spare to swap out? What if I'm just curious? I'd like to know load input voltage. I could just VOM the adapter tip but it just isn't representative of voltage under load. Anyone out there know of anything like this?
