>From 3e7b4da3783d200f35568f72b3b25f16df546ffe Mon Sep 17 00:00:00 2001 From: Zhang Rui <rui.zhang@xxxxxxxxx> Date: Fri, 30 Nov 2012 14:35:43 +0800 Subject: [PATCH] ACPI : do not use Lid and Sleep button for S5 wakeup When system enters power off, the _PSW of Lid device is enabled. But this may cause the system to reboot instead of power off. https://bugzilla.kernel.org/show_bug.cgi?id=35262 A proper way to fix this is to always disable lid wakeup capability for S5.
