Subject: [PATCH] ACPI / EC: Use ec_no_wakeup on ThinkPad X1 Yoga 3rd
Date: Tue, 31 Jul 2018 18:52:39 +0800 [thread overview]
Message-ID: <20180731105239.22008-1-aaron.ma@canonical.com> (raw)
Like on X1C6, on X1Y3 EC interrupts constantly wake up system from
s2idle, the power consumption is extremely high.
So make ec_no_wakeup be true as default to keep system in s2idle mode
and reduce power consumption.
Power button works when ec_no_wakeup=true.
