it is from the buggy firmware.

form the ACPI DSDT table
the device HS10~ HS15, method _PLD checks with the method PR2S with value 0x0A ~ 0x0F,
                    Method (_PLD, 0, Serialized) // _PLD: Physical Location of Device
                    {
                             ...
                        If (LNot (And (PR2S (0x0A), PR2))) <---

                            And (VIS, Zero, VIS)
                        }

                        Return (PLDP)
                    }
                }

But the PR2S no return, when the LBC CDID not equal 0x8xxx
            Method (PR2S, 1, Serialized)

                                        }
                                    }
                                }
                            }
                        }

                        Break
                    }
                }

if the CDID value is not equal 0x8xxx, it cause no return for method PR2S.
