<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">You don't need that much logic - when batteryChargeStateChanged is emitted it is guaranteed the state is not the same as it was before. So you could simply fire the notification if the state went to NoCharge and AC is plugged. Test this solution - if you get false positives we might add more checks, but I am pretty sure the AC plugged check is more than enough for making it reliable.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I tried it again and it seems that (m_backend->acAdapterState() == BackendInterface::Plugged) is always false when this slot is triggered. Without it my new logic works fine.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Indeed, I am not saying your logic is wrong (apart from the comment below) - it's simply not needed, as the checks you are doing are already implied in the emission of the slot. It really surprises me it works though, the problem I outlined below should prevent it from working in any situation in theory, or maybe I completely overlooked something.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I mean, I cleaned up the logic and made it simpler (with the loop, so it checks if *all* batteries are charged). It works, but the check for AC adapter plugged in always fails, so the notification is not issued. But that should really only show up if the adapter is plugged in, to prevent false positives (e.g. NoCharge can also mean error, or sth else went wrong)</pre>

This is really bad then, also because that check should definitely work. Maybe try outputting the output of m_backend->acAdapterState() every time it should change and check if there's anything going on?</pre>
