battery power percentage

[elmo]

I have a laptop.
I use WinXP.

If my laptop battery almost empty, there will be a notification "Low battery" on the taskbar.
I had searched a code in this forum about how to do it. But I found nothing.

So the problem is: how to get ampere/volt/vendor of battery installed in my laptop with MASM code?

Would you like to give me a clue?
Thank you.
Make program with MASM is very interesting. :U

It depends on your hardware as to how much information you will get.... As far as I remember some laptops will *only* tell you when you have a few percentage points left....

GetSystemPowerStatus

ok this is the solution

      invoke GetSystemPowerStatus,ADDR SPS
      .if SPS.BatteryLifeTime == -1
         invoke MessageBox,hWin,SADD("Batery almost empty. Prepare to shutdown"),SADD("info"),0
      .else
         invoke MessageBox,hWin,SADD("Batery not empty"),SADD("info"),0
      .endif
