I found there was a error when power supply plugged in with system in s2idle status. And then pressing key to wake up the system, I found the system was wakeup after a while.

The log is this:
```
[ 3670.017466] No Local Variables are initialized for Method [ERCD]

[ 3670.017513] Initialized Arguments for Method [ERCD]: (1 arguments defined for method invocation)

```

From the log and the source of ACPI, I found the ACPI was waitting for the event of the EC to be completed.
But that is not occurred every time.

 

My laptop is ThinkBook 14 G3 iTL

You need to contact Lenovo about this issue. The ACPI 'code' is specified as part of the tables in the system's BIOS, thus making the motherboard/laptop vendor responsible.
