Laptop/Tablet BatteryCycleCount for Determining its Health
<p>Please help me to get Laptop/Tablet "BatteryCycleCount" value. Based on this property we will determine the replacement of battery.
Below are some APIs, which i have found in my googling:</p>

<pre><code>[DllImport("setupapi.dll", SetLastError = true)]
protected static extern IntPtr SetupDiGetClassDevs(ref Guid gClass, [MarshalAs(UnmanagedType.LPStr)] string strEnumerator, IntPtr hParent, uint nFlags);

[DllImport("setupapi.dll", SetLastError = true)]
protected static extern bool SetupDiEnumDeviceInterfaces(IntPtr lpDeviceInfoSet, uint nDeviceInfoData, ref Guid gClass, uint nIndex, ref SP_DEVICE_INTERFACE_DATA oInterfaceData);

[DllImport("setupapi.dll", SetLastError = true)]
protected static extern bool SetupDiGetDeviceInterfaceDetail(IntPtr lpDeviceInfoSet, ref SP_DEVICE_INTERFACE_DATA oInterfaceData, ref SP_DEVICE_INTERFACE_DETAIL_DATA oDetailData, uint nDeviceInterfaceDetailDataSize, ref uint nRequiredSize, IntPtr lpDeviceInfoData);

[DllImport("kernel32.dll", SetLastError = true)]
protected static extern IntPtr CreateFile([MarshalAs(UnmanagedType.LPStr)] string strName, uint nAccess, uint nShareMode, IntPtr lpSecurity, uint nCreationFlags, uint nAttributes, IntPtr lpTemplate);

[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool DeviceIoControl([In] SafeHandle hDevice, [In] int dwIoControlCode, [In] IntPtr lpInBuffer, [In] int nInBufferSize, [Out] IntPtr lpOutBuffer, [In] int nOutBufferSize, out int lpBytesReturned, [In] IntPtr lpOverlapped);
