Dell Optimizer Dual Battery Issue

The following three issues can be seen when using Dell Optimizer version 4.0.111.0 and dual batteries (Figure 1):

Figure 1: Dual Battery Example

1. "About My Battery" will be missing (Figure 2):
   
   Figure 2: Dell Optimizer, About My Battery
    

   Battery Placement	"About My Battery" Present
   Slot 1 + Slot 2	Yes – For the Slot 2 Battery
   Slot 1 Only	No – Feature Missing
   Slot 2 Only	Yes – For the slot 2 Battery

2. Power features "Advance Charge" and "Charging Mode – Adaptive, Primarily AC, and Custom" are missing (Figure 3) (Only affects Latitude 7230 Rugged Extreme Tablet):
   
   Figure 3: Dell Optimizer Charging Modes Missing
    

   Battery and Slot	Advanced Charge Present	Charging Mode Present
   Battery 1 in Slot 1	Yes	All Modes Present
   Battery 2 in Slot 1	Yes	All Modes Present
   Battery 1 in Slot 2	No	Only Standard and Express Charge
   Battery 2 in Slot 2	No	Only Standard and Express Charge
   Both Batteries	No	Only Standard and Express Charge

3. “Dynamic Charge Policy” and “Charging Mode” options are grayed out (Figure 4 and 5). There are two scenarios for this behavior.
   1. Scenario 1 – Set the charging mode to “Custom” in the BIOS for Battery 1.
      Then “Dynamic Charge Policy” is disabled and grayed out without tooltip “Dynamic charge policy is not supported when a custom charge mode is enabled” but “Charging Mode” is shown as set to “Standard” (the selected charging mode for Battery 2) (Figure 4).
      
      Figure 4: Dell Optimizer, Dynamic Policy Grayed Out without Tooltip
   2. Scenario 2 – Set Charging Mode to “Custom” in BIOS for Battery 2.
      Then “Dynamic Charge Policy” is ON and grayed out but still shows tooltip “Dynamic charge policy is not supported when a custom charge is enabled” and “Charging Mode” is grayed out and shows tooltip “Charging Mode is being managed by Dynamic Charge Policy” (Figure 5).

1. Missing “About My Battery” Issue – Dell Optimizer detects the first battery listed by enumerating the battery and slot 2 is the first one listed in Windows.
2. Missing “Advanced Charge” and “Charging Mode – Adaptive, Primarily AC, and Custom” Issue – BIOS returning incorrect values.
3. Grayed Out “Dynamic Charge Policy” and “Charging Mode” Issue – Dynamic Charge Policy checks the first battery on the SMBIOS, but charging modes check the first battery from the Windows API. The order from these two sources is different. From a Dell Optimizer aspect, we do not define the battery order for multiple batteries yet.
