System: Windows 10 Pro Battery or AC: Battery Model: ASUS ExpertBook B9450FA-BM0345R Frequency of occurrence: Always Reset OS: I have updated Windows version to the latest one but the problems remain. Screenshot or video: ======================== 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 - OS State Data Data obtained from the Event Viewer Logger. - Detailed OS State Data Name Value TargetState 5 EffectiveState 5 ProgrammedWakeTimeAc 1601-01-01T02:00:00 WakeRequesterTypeAc 0 ProgrammedWakeTimeDc 1601-01-01T02:00:00 WakeRequesterTypeDc 0 Attributes 1921007617 BiosInitDuration 1768 DriverInitDuration 678 EffectiveState 5 HiberPagesWritten 220484 HiberReadDuration 1591 HiberWriteDuration 1191 NoMultiStageResumeReason 0 SleepDuration 1730 SleepTime 2020-08-25T19:25:00 TargetState 5 WakeDuration 840 WakeSourceType 0 WakeTime 2020-08-25T21:21:55
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
