Detailed description:

Hi, I noticed weird blinking of the power button (and the LED on the side too) when in sleep mode. This seems like an error? Happens both when connected to power and on battery.

I It blinks every 2 seconds or so, and its a very rapid blink, short pulse. have tried the hard reset, holding the power button for 30 seconds while disconnected from AC, still the same behavior.



  • Hello brai1234,

    May you help to check your BIOS version?

    and run Windows update to see if KB4586781 has been updated.

    Thank you.

  • I have the latest BIOS version available, 307.

    There are no updates available in WInodws update, but I don't see 4586781 under installed updates.

    Hello brai1234,

    May you enter BIOS and load default setting again?

    And please kindly share the video of the issue ( you may put a space within the link)

    If the device enter Hibernate mode, or completely shut down, does the power button blinks?

    Thank you.

  • Hi,

    BIOS reset did nothing

    The power button does not blink when hibernating or shutdown.

  • Hello brai1234,

    Thank you so much for the video.

    I have double check with our technical support, this blinking is normal under sleep mode.

    Please do not worry about it.

  • Thank you, have a nice day!
