1 year ago This only applies to some 300-series motherboards that don't have a legacy RTC device implemented (hence why it's disabled). Your RTC device is fairly standard and can be enabled by setting the STAS to One:
DSDT.aml .. RTC Device
```dsl
19238 | Device (RTC)
19239 | {
19240 | Name (_HID, EisaId ("PNP0B00") /* AT Real-Time Clock */) // _HID: Hardware ID
19241 | Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
19242 | {
19243 | IO (Decode16,
19244 | 0x0070, // Range Minimum
19245 | 0x0070, // Range Maximum
19246 | 0x01, // Alignment
19247 | 0x08, // Length
19248 | )
19249 | IRQNoFlags ()
19250 | {8}
19251 | })
19252 | Method (_STA, 0, NotSerialized) // _STA: Status
19253 | {
19254 | If ((STAS == One))
19255 | {
19256 | Return (0x0F)
19257 | }
19258 | Else
19259 | {
19260 | Return (Zero)
19261 | }
19262 | }
19263 | }
```
I have a similar SSDT named SSDT-AWAC that does this (src/ACPI/SSDT-AWAC.dsl#L14).
Right, you already have this SSDT implemented.
