I'm having an issue where custom battery charge thresholds aren't being respected on my E5550 when I plug my laptop into AC power.
Steps to replicate:
Using Dell Command | Power Manager, set custom battery settings such that the battery will start charging at 80% and stop charging at 90%.
Unplug from AC power.
Discharge the battery to anywhere below 90% but not below 80%.
Plug-in to AC power.
The battery will charge when the laptop is connected to AC power despite the battery charge state being above the custom 'start charge' point of 80%.
The battery should not charge unless it is is below the custom 'start charge' point.
Using V 2.1.1 of Power Manager and the A13 (latest) BIOS.
This looks like a bug in the battery charger firmware to me. Anyone else?
