Battery Driver Registry Settings

  • Article

The following registry key example shows the battery driver registry keys.

IF BSP_NOBATTERY !

; HIVE BOOT SECTION

[HKEY_LOCAL_MACHINE\System\Events]
    "SYSTEM/BatteryAPIsReady"="Battery Interface APIs"

; END HIVE BOOT SECTION

; These registry entries load the battery driver.  The IClass value must match
; the BATTERY_DRIVER_CLASS definition in battery.h -- this is how the system
; knows which device is the battery driver.  Note that we are using 
; DEVFLAGS_NAKEDENTRIES with this driver.  This tells the device manager
; to instantiate the device with the prefix named in the registry but to look
; for DLL entry points without the prefix.  For example, it will look for Init
; instead of BAT_Init.  This allows the prefix to be changed in the registry (if
; desired) without editing the driver code.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Battery]
   "Prefix"="BAT"
   "Dll"="battdrvr.dll"
   "Flags"=dword:8                      ; DEVFLAGS_NAKEDENTRIES
   "Order"=dword:0
   "IClass"="{DD176277-CD34-4980-91EE-67DBEF3D8913}"

ENDIF BSP_NOBATTERY !
