There are 2 `((` in the generated ACPI code:

```
            Method (_ON, 0, Serialized)  // _ON_: Power On
            {
                Local0 = _STA ()
                If ((Local0 == One))
                {
                    Return (Zero)
                }

_SB.CTXS (0x84)
                Sleep (0x01F4)
            }
```
