Detailed description:

Greetings,

From the beginning I have the problems with my laptop in modern standby mode (while disconnected from AC).

The first problem is that the laptop doesn't stay in standby mode more than roughly 10 hours due to forced hibernation. Windows SleepStudy reports it as «Drain (dozed to hibernate because the standby battery budget was exceeded)». In Windows system events we can read «Hibernate from Sleep — Standby Battery budget Exceeded». With no devices connected to the laptop (and «NETWORKING IN STANDBY» Disconnected), battery drain in standby mode is at least 336 mW per hour (3511 mW per 10h 27min 36sec, 3621 mW per 10h 13min 7 sec, 3370 mW per 9h 11min 25sec). Battery drain in sleep mode is bigger than in simple Screen Off (956 mW per 2h 59min 49sec).

The second problem - when battery drain is very high (due to internal Windows processes or external load, for example smart-phone charging) the laptop transits to unknown state, unresponsive to power button click and with significant energy consumption; the only way to leave that state is 15 sec power button pressing.

Could it be a hardware problem? Please help me to figure out the cause of the problems with the laptop and, if possible, suggest how to fix them.

    Hello yanouski,

    May I know your BIOS version and if you are on Windows 2004 or 1909?

    So you would like to have more than 10 hours on stand by mode? I will check on that for you.

    Please kindly provide the task manager screenshot as well.

    Please do understand that in standby mode, even wifi is on, so there is a lot of things still working, it is very likely to have battery drain if you did not close programs in the background .

    For your second problem, may you specify more? like how long have you charged the phone and the issue occurred?

    The unknown state means the device is stuck? lagging ? any error message? black screen? BSOD?

    Please kindly use My ASUS and Windows troubleshooting to run some simple diagnostic.

    Thank you.

  • Hello Blake_ASUS,

    thank you for your response.

    BIOS 303, Windows 2004.

    Is it expected for the laptop that the standby mode would always be "orange" in Windows Sleepstudy report (powercfg /sleepstudy) ?

    For the second problem, maybe it was not clear from my description that it concerns only standby mode (without AC). It occurs after on hour and several minutes after the beginning of my smart-phone charging. The laptop is stuck (doesn't respond to lid opening and power button click). Windows Sleepstudy report says the laptop is in hibernation (EXIT REASON   0x14 (Hibernate, or Shutdown)), but it continues charging my smart-phone.

    An example of the state description from Sleepstudy report:

    System Power State: Hibernate

       START TIME   DURATION   STATE   ENTRY REASON   EXIT REASON   % CAPACITY REMAINING AT START   

    179   2020-08-25 19:25:02   1:56:54   Hibernate   Hibernate from Sleep - Standby Battery Budget Exceeded   Unknown   -

    I'd like to add that the "unknown EXIT REASON" was 15 power button press, it was the only way to interact with the laptop.

    And I have already run My ASUS troubleshooting (and now also Windows troubleshooting for "power").

    Sincerely,

    Aleksander


  • Hello yanouski,

    Would you mind to share the original report ? If you have concern, you may share it in the PM I send you.

    Then for the standby mode, please kindly try to adjust the setting or close unnecessary programs and function before go to stand by mode, so that your battery would last longer.

    For the battery changing thing, may you double check what % was the battery when the issue happened?

    Thank you.

    Hello Blake_ASUS,

    thank you for your response,

    Events № 23 and 178 correspond to smart-phone charging in standby mode.

    "Then for the standby mode, please kindly try to adjust the setting or close unnecessary programs and function before go to stand by mode"

    The only program I have installed is VLC media player (so the system could be named "almost as from factory"). It would be nice if you (or somebody else) provide the expected battery drain values in standby mode for ASUS ExpertBook B9450FA with default (factory) Windows settings, so that I could compare them with mine.

    "For the battery changing thing, may you double check what % was the battery when the issue happened?"

    Please clarify whether you are talking about the mW values in my first post or about battery % values when I connected my smart-phone.

    Sincerely,

    Aleksander

  • Hello Aleksander,

    Thank you for the sharing.

    For the coloring thing....I don't have much information about it, but I don't think it would affect the report.

    So you would like to know when you don't open any windows, but also don't adjust anything, how long can the standby mode last?

    I will see if I can test or find anything more for you.

    I would like to know when you device got stuck by the phone charging, around that moment, what % of battery is it.

    I don't need to know how many mW was lost during the charging process.

    Thank you.

  • Hello Blake_ASUS,

    when the laptop got stuck by the phone charging the battery value was 78% (after event 23) and 81% (after event 178), and I suppose it would happen at any battery charge %.

    "For the coloring thing....I don't have much information about it, but I don't think it would affect the report."

    It should be "green" under low system activity.

    "So you would like to know when you don't open any windows, but also don't adjust anything, how long can the standby mode last?"

    Yes, and I would also like to know the expected battery drain values (in mWh) in standby mode for ASUS ExpertBook B9450FA with default (factory) Windows settings.

    Thank you.

  • Hello Aleksander,

    Would you mind rollback to 1909 since it's more stable?

    Thank you.

  • Hello Blake_ASUS,

    I had the same problems on Windows 1909.

  • Hello Aleksander,

    I see. Let us dig in to some more then get back to you.

    Thank you.

  • Hello Aleksander,

    I tested it myself with a device having fresh setup.

    I did not open any program and only switch to "Airplane mode",

    let the device stay in "sleep mode" for 8 hours without 1% battery drop.

    you may consider adjusting your setting.

    And it would be easier to find out more for the second problem if the variables are less and narrowed down.

    Thank you.

  • Hello Blake_ASUS,

    thank you very much for the test.

    I did exactly the same, but unfortunately, had the battery drain as before (even more, than it was in some cases) and the laptop was forced to hibernation after 9 hours and 14 minutes (see sleep report). Battery dropped 6% (58 to 52%).

    To make sure it's not Windows fault I will restore the system to factory default and repeat the test.

    What specific information do you need for the second problem?

    Sincerely,

    Aleksander

  • Hello Aleksander,

    In this case, I think the battery needs to be checked.

    Please kindly send your device to service center.

    Really sorry for the inconvenience caused.

    Thank you.

  • Thank you Blake_ASUS.
