Get Battery Status: High, Low & Very Low

[Guest]

Hi,
I am working on a PPC 2003 Device.
I want to get the Battery Status that is displayed in the Control Panel as
High, Low or Very Low.

Can some one tell me how i can get that.
I am using the below API Call to get the Percentage of Battery Charge left.
[DllImport("coredll")]
public extern static bool GetSystemPowerStatusEx(ref YSTEM_POWER_STATUS_EX
sps, bool fUpdate);

In one of our PPC 2003 Devices the Percentage of Battery Charge is displayed
as "Unknown". What is the Reason and Can something be done to get the
Percentage Battery charge.

The device may show Unknown shortly after turned on before it is able to
properly update, or when the device is charging on external power...

The reason is that the device/battery driver doesn't know. If the hardware
doesn't know, no, you can't magically determine that.

Thanks for your Prompt Response.

It's showing somewhere. You don't necessarily know that the battery driver
is providing that information. The OEM for the device can do *anything*
they want to. The two things that I can think of are a) you're doing
something wrong in your declaration of the type passed to that call, b) the
OEM doesn't use that call to report battery status. If a), fix it. If b),
there's nothing you can do unless you can find what call the OEM *is* using
and use that yourself.

And I guess I should say that the best way to decide whether the problem is
a) or b) is to write the code in C/C++ and see if you get the right answer
*that* way.
