With a lot of solar equipment, the tech support has access to a lot of settings us installers don't, so we've had times where we tell the tech that we've done everything we can, including restarting it (and with my experience with Generac inverters, restarting them can and will break something!), and sometimes it really feels like they do click a magic button, say "how about now?", then it works

Or they shutdown and turn it back on, which doesn't count in windows as restarting unless you disable fast-startup. So you get annoyed tech support thinking the user is a liar and an annoyed end user that knows they turned it off and on again.

Or turned off the monitor and turned it back on.

As someone working as on-site IT support for over 15 years, I can't tell you how often I have asked people to restart their computer over the phone and they swore they did ("multiple times even"), only for me to eventually come around to their desk and having them actually reboot the device in my presence and for the problem to actually fix itself.

One Lady I asked to restart their computer said "all right, hold on." only to respond not even 10 seconds (!) later "I did, its still not working„ and after the third time I went to her desk and asked her to show me what she did. She leaned forward, turned off the monitor, then turned it back on. "I did this 10 times already, and its still not working".

Some people just lie about rebooting, some simply don't actually know how to reboot properly. After a few months, you get to know who's lying, who's doesn't know better and who's actually telling you the truth, you get to know your coworkers.

well shutdown isn't a full restart anymore, it literally saves your issues and reloads it when it turns on. so we have to doublecheck that too. it should count as restart, but doesn't.
