Windows 10: Battery dies as soon as laptop wakes up from sleep/hibernation

I am at a loss, my laptop can be at full charge, and if it falls asleep or is hibernated, and woken up even a minute later, after booting up, the battery is completely drained. I have no idea why. The battery maintains its charge normally, and can be used for a long time. What can be the cause of this?

wake from sleep but not hibernation

No problem . I assume you did not enable wake timers while "on battery" before hibernating.

If this was s3 sleep then it I guess this would be the expected behavior as you did not enable wake timers "on battery" and when you put the pc to sleep/hibernation then windows will probably detect that you were on battery power and that that wake timers are not allowed in battery mode before going into sleep, as s3 sleep is just "sleep" with no cpu so it had no way of knowing that now your connected to ac power when it is either in sleep/hibernate and follows the options you setup before you put the pc to sleep/hibernate.

Sorry, I don't know how modern standby works but #21 suggests that denis had either enabled wake timers on battery, if not this is the expected behavior like you concluded .

 

Task scheduler wakes from sleep/hibernation but PC then goes back to sleep/hibernation

Hi,

I have a HP EliteBook 840 G1 with Windows 10.

I am looking to put my laptop to sleep/hibernation each night at a set time. Then the scheduler will wake the PC at a set time and run a .bat file.

The Windows scheduler wakes the PC fine but after a few minutes it goes back to sleep/hibernation. I would appreciate any suggestions to prevent this.

The laptop is connected to power the whole time and I have disabled auto sleep.

Thanks,

 

wake from sleep but not hibernation

An interesting observation.
- I've just tested on mine and it behaved itself [power removed, hibernated, power reconnected - it woke up correctly].
But I did also observe one unexpected behaviour - the laptop's display did not turn on until I moved my mouse. So that's one more item on the list of things to investigate in the fullness of time.
I repeated this using sleep instead of hibernate and the result was the same.
I've seen people reporting this lately but have never noticed it myself before. I've probably been grabbing the mouse ready to do something so not noticed the screen waiting for that until it came on.
