From 4a6cf0c4f4f8465d61adbf3aaaec2bd100e30d97 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 4 Dec 2012 23:23:16 +0100 Subject: ACPI : do not use Lid and Sleep button for S5 wakeup commit b7e383046c2c7c13ad928cd7407eafff758ddd4b upstream. When system enters power off, the _PSW of Lid device is enabled. But this may cause the system to reboot instead of power off. A proper way to fix this is to always disable lid wakeup capability for S5. References: https://bugzilla.kernel.org/show_bug.cgi?id=35262 Signed-off-by: Zhang Rui Signed-off-by: Rafael J.
