dmesg until failure
On the Microsoft Surface 3, when you fold the type cover over the screen (or
"close the lid"), the lid switch state does not change, and an ACPI error is
thrown. The lid switch state always reports closed.
[root@localhost ~]# cat /proc/acpi/button/lid/LID/state
state: closed
[ 1130.459896] ACPI Exception: AE_ERROR, Returned by Handler for
[GeneralPurposeIo] (20150930/evregion-297)
[ 1130.460061] ACPI Error: Method parse/execution failed [\_SB.GPO0._E4C] (Node
ffff88013f4b4438), AE_ERROR (20150930/psparse-542)
>From the DSDT, this is the GPIO event handler that toggles the lid switch
state.
