Another Debugging question DSDT

[NaxiumEQ]

Not all control Paths return a value (SIOS)

Is there a way to fix this? Did I miss a patch somewhere?

 

Method (SIOS, 1, NotSerialized)
               {
                   Store ("SIOS", Debug)
                   If (LEqual (One, Arg0))
                   {
                       ^SIO1.ENFG (0x0A)
                       And (^SIO1.RGE0, 0x9F, ^SIO1.RGE0)
                       If (KBFG)
                       {
                           Or (^SIO1.OPT6, 0x10, ^SIO1.OPT6)
                       }
                       Else
                       {
                           And (^SIO1.OPT6, 0xEF, ^SIO1.OPT6)
                       }
                       If (MSFG)
                       {
                           Or (^SIO1.OPT6, 0x20, ^SIO1.OPT6)
                       }
                       Else
                       {
                           And (^SIO1.OPT6, 0xDF, ^SIO1.OPT6)
                       }
                       Store (0xFF, ^SIO1.OPT3)
                       Store (0xFF, ^SIO1.OPT4)
                       Or (One, ^SIO1.OPT2, ^SIO1.OPT2)
                       ^SIO1.EXFG ()
                       Return (Zero)

 

Thanks for the help!

This is not an error, it's just a warning.

To avoid it, add Return (Zero) before the last } of the method.

Forgive me as I am extremely new to this whole thing....otherwise it can be ignored?

Again, Thanks

[Cassio]

No, "before the last } of the method".

If you post the entire method I can show you.

[NaxiumEQ]

I didn't realize there was more to the method lol.

I think I got it now, after recompiling the warning disappeared. I appreciate your patience cassio!

Do you think you might be able to check over my dsdt and tell me if I'm missing anything or on the right track?
