Does this laptop have a free fall sensor?
Seems like gpe13 tries to notify your SATA controller something. Or
maybe it's related to the ExpressCache?
Scope (_GPE)
{
Method (_L13, 0, NotSerialized) // _Lxx: Level-Triggered GPE
{
If ((PFLV == FDTP))
{
Return (Zero)
}
GPE3 = Zero
GL08 |= 0x10
Notify (\_SB.PCI0.SAT0, 0x82) // Device-Specific Change
Return (Zero)
}
}
