Gnome-power-manager suspends laptop when UPS battery is low

[Chris Irwin]

I've got a laptop with it's own battery. When I dock it at my desk, it also has a UPS (which powers my switch, monitor, etc).

When the UPS battery reports itself as low, the laptop suspends itself, even though the internal battery is 100%, meaning I have about 3-4 hours of battery time remaining.
