USB connected UPS reported as internal power

[Dan Schafer]

Setup:
Ubuntu Gutsy with basic power management settings (shutdown when critical)
Dell Inspiron 8600
2x laptop batteries
1 UPS connected via USB (CPS CP 1300D)
AC Power unplugged

The laptop was unplugged from AC power by accident and was correctly placed on Battery Mode. After both batteries discharged completely, the system shutdown without warning. The UPS was still listed in the notification area icon as 100% with 1 hour 31 minutes charge time, even though the computer was on battery power and had no way of drawing power from the UPS.

I believe that it miscalculated the remaining time available on battery power because of the UPS being connected. Because of this, it never properly warned me to shutdown, or to plug it back in.

Is this still an issue on a more recent and supported release?

I don't have that laptop anymore, but I'll test it with a couple laptops
over the next few days.

Also from your description, it sounds like what happened is that the
laptop was not plugged in to the UPS. Even though it was monitoring the
UPS status, it was not drawing power from it, instead running from the
internal battery, which then ran out. If that is the case then there
isn't a bug there.
