From 00e250367cc6c4ab80fea6ec605d464e624bd520 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 26 Oct 2019 22:24:35 +0200 Subject: [PATCH] ACPI: button: Add DMI quirk for Asus T200TA The Asus T200TA lid has some weird behavior where _LID keeps reporting closed after every second openening of the lid. Causing immediate re-suspend after opening every other open. I've looked at the AML code but it involves talking to the EC and we have no idea what the EC is doing. Setting lid_init_state to ACPI_BUTTON_LID_INIT_OPEN fixes the unwanted behavior, so this commit adds a DMI based quirk to use ACPI_BUTTON_LID_INIT_OPEN on the T200TA.
