Detailed description:

Hi, since the begining I have issues with my laptop in sleep mode. The battery drain because of the modern standby mode.

I followed the procedure here to disable the modern standby : asus.com/support/FAQ/1035447/

But now my computer doesn't wake up when in sleep. It's incredibely annoying.

How can I fix that ?

Thank you and have a nice day,

Jérôme.

  • Hello Jérôme,

    May you check if your BIOS and Windows are up to date?

    (BIOS 317 and Windows 1909)

    And may you try to see which program is running during the standby mode?

    Thank you.

    Hello Blake, thank you for your answer.

    You will find the reports in attachment.

    I disabled the wifi during sleep, so now I "only" loose 1% each 45 minutes in sleep.

    How can I fix that ?

    Thank you for your precious help,

    Jérôme.

    Hello Jérôme,

    If you did not plug in AC, I would say 1% every 45 min sleep now seems normal.

    If you wish to save more power, maybe set your device to hibernate after sleep mode for a while.

    Also, please double check if your Windows has updated to 1909 and complete all the KB update.

    Thank you.

  • Reasons for Battery drains could not be found out. I need to analyis other report ,say energy report for 5 minutes.

    Ok, thank you. What these commands do ?

  • Those commands disable hybernation.

    Set the display turn off after 2 minutes

    Set the system to sleeps after 3 minutes

    Turn off the hard-disk after 5 minutes

  • I can't post anymore?

    Could it be the Intel Management Engine Interface draining the battery?

  • But outdated firmware causes.

    Intel me firmware is directly embedded into processor , and processor handles the battery through windows OS.
