Hi,
I've searched the net now for a few hours and the only code to control the ACPI driver + the Mail LED was this one:

Code:
#include 
HANDLE ATKACPIhandle;

int WINAPI WinMain (HINSTANCE hThisInstance,
                    HINSTANCE hPrevInstance,
                    LPSTR szCmdLine,
                    int nFunsterStil)

{
    HWND hwnd;                       
    WNDCLASSEX wincl;        
    
    DWORD bytes = 0;
	struct cmbuf {
		short cmds[2];
		long cm2;
	} cbuf;
	long outbuf[192];

	cbuf.cmds[0] = 0;
	cbuf.cmds[1] = 4;
    if (strcmp(szCmdLine,"0"))
		cbuf.cm2=0;
    else if (strcmp(szCmdLine,"1"))
		cbuf.cm2=1;
	else return 0;

	long inbuf[5]={2,0x44454c4d,1,8,(long)&cbuf};

	ATKACPIhandle = CreateFile("\\\\.\\ATKACPI",
			GENERIC_READ|GENERIC_WRITE,
			FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING,
			0, NULL);

	if (ATKACPIhandle){ 
    DeviceIoControl(ATKACPIhandle, 0x222404, inbuf, sizeof(inbuf),
		outbuf, sizeof(outbuf), &bytes, NULL);
	CloseHandle(ATKACPIhandle);}
    return 0;
}

It works perfectly fine but I haven't found any other codes to control other LEDs of the G71v / G50s

I've only found those, but they dont work with the G71V (only the MLED works):
Code:
#define MLED	0x44454c4d
#define TLED	0x44454c54
#define WLED	0x44454c57

#define LED	0x44454c00
Does anyone know where I can find the codes for the G71V?


Thanks very much in advance, it would be really cool if any1 had them
