Subject: [PATCH] ACPI: EC: Use ec_no_wakeup on ThinkPad T14 Gen 5
Date: Tue, 18 Jun 2024 18:51:33 +0900 [thread overview]
Message-ID: <ZnFYpWHJ5Ml724Nv@ohnotp> (raw)
On ThinkPad T14 Gen 5, EC interrupts constantly wake up the system from
s2idle, resulting in high power consumption.
This sets `acpi.ec_no_wakeup=1` to fix the high power consumption issue
in s2idle state.
