  1. ACPI wakeup timer wakes laptop 3hs after sleep


    Hi

    I've seen this posted several times and no solutions given so I don't have much hope.

    My Gigabyte AERO 15 laptop wakes itself up automatically 3 hs after I set it to sleep.

    I noticed it woke up but I only noticed the 3hs period after running the "powercfg /SLEEPSTUDY" command and noticing that all the sleep periods that ended with a wakeup due to ACPI Wake Alarm lasted exactly 3 hours.

    When opening the section in that element called "Detailed OS State Data" I can see that there is a programmed wakeup timer set exactly upon entering sleep. All standard solutions such as disabling wakeup timers have been tried with no results.

    Can please someone help me?

    As of now I cannot leave my comp in a sleep state for ex inside a backpack and trust it will remain so after 3 hs.

    Thanks!

    In this screenshot you can see that upon entering sleep at 1:07:22 the computer sets a ProgrammedWakeTime at 4:07:22 - in all cases it is the same, exactly 3 hs after sleep

    laptop with windows 10 wake up by itself (and drain my battery)

    It happens couple of times since I have windows 10 installed on my laptop

    I troubleshoot a bit but can't find out what's causing it

    troubleshooting steps

    1. open command prompt and type 'powercfg -lastwake'

    Result: wake history count - 1

    wake history [0]

    wake source count - 0

    OK, it does wake up but doesn't tell me anything

    2. 'powercfg - devicequery wake_armed

    Result: HID keyboard and mouse

    I know that I do not have HID keyboard, so this is not the problem. Mouse I have is bluetooth mouse, but I always turn it off.

    Action: I turned off both devices, but still wake up the laptop

    3. find out the wakeup timers

    powercfg -waketimers

    Result: no wakeup timers in the system

    4. find out from poweroption -> advanced settings

    in Sleep -> allow wakeup timers, the default is on battery: disable , plugged in : important wake timers only

    I know that my laptop only wake up while it's on battery as it drains it to almost 0 twice, and this setting is disable

    So I am out of clue on what's waking up the laptop.

    Can someone help me troubleshot?

    Thanks.
