Yes. This is exactly the same:

                     Method (_HID, 0, NotSerialized)  // _HID: Hardware ID
                     {

                         {
                             Return (0x190A2E4F)
                         }

                         If (ALPS)
                         {
                             Return (0x0713A906)
                         }

                         If (ELAN)
                         {
                             Return (0x08018416)
                         }

                         If (STLC)
                         {
                             Return (0x41C18C4E)
                         }

                         If (FOLT)
                         {
                             Return (0x02019419)
                         }

                         Return (0x060A2E4F)
