Bug ID: 210421
Summary: MacBookAir5,2 doesn't wake from S3 by RTC alarm
Product: ACPI
Version: 2.5
Kernel Version: 5.9.10-arch1-1
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Sleep-Wake
Assignee: acpi_power-sleep-w...@kernel-bugs.osdl.org
Reporter: p...@techiemedia.net
Regression: No
Overview:
MacBookAir5,2 doesn't wake from S3 by RTC alarm when lid is closed and power
adapter is disconnected.
Steps to Reproduce:
Run 'rtcwake -m mem -s +15', wait for laptop to go to sleep then close the lid
Actual Results:
Nothing happens
Expected Results:
Laptop wakes up in ~15sec
Build Date & Hardware:
Linux air.plv.loc 5.9.10-arch1-1 #1 SMP PREEMPT Sun, 22 Nov 2020 14:16:59 +0000
x86_64 GNU/Linux
MacBookAir5,2
Additional Information:
Sleep/resume by lid close/open works fine without any tweaks. But the laptop
would resume shortly if suspended with lid open and LID0 enabled in
/proc/acpi/wakeup.
Anyway, the status of LID0 wakeup doesn't affect RTC wakeup.
Wakeup by RTC alarm works if either the lid is open or ADP1 is online.
