For notifications it uses an ActiveLow Edge GpioInt, rather then an ActiveBoth one, meaning that the device is only notified when the lid is closed, not when it is opened. 2. Matching with this its _LID method simply always returns 0 (closed) In order for the Linux LID code to work properly with this implementation, the lid_init_state selection needs to be set to ACPI_BUTTON_LID_INIT_OPEN, add a DMI quirk for this. While working on this I also found out that the MD60### part of the model number differs per country/batch while all of the E2215T and E2228T models have this issue, so also remove the " MD60198" part from the E2215T quirk.
