I have a HUGE battery drain while power off (not hibernating)  at least 5-10 percent per day.   I windows updates done.   I used to think it was because of the keyboard being attached. but I have switched to a Brydge Keyboard.  Does anyone else have this issue or know how to fix?

Thanks!

Thanks Victor_S

Another solution I've found is to shut down the computer the old way - regular shutdown instead of hybrid shutdown.

You can use this shortcut:

C:\Windows\System32\shutdown.exe /s /t 3 /c "Full Shutdown"

  • shutdown.exe can execute the various sleed/hibernate commands, including the regular shutdown.
  • /s means "shutdown". If we shutdown the normal way, it is a hybrid shutdown (/hybrid)
  • /t 3 means after 3 seconds. If you skip this it's 30 seconds by default.
  • /c "Full shutdown" is a simple comment that will appear in various places as the reason for your shutdown.

Keep in mind it takes a little longer to shutdown this way, and it takes a little longer to start afterwards, but I think the computer doesn't keep some systems active, thus you should see almost no battery drain, even for prolonged times.

That is a good question because the screen will be off.  Before shutting down and all programs are closed, you can do a CTRL+ALT+DEL and select the task manager and look at the processes that are still running at that moment and you may find 'something' but doubtful.

The power sub-system could also have a defect causing that as well and not actually shutting off the machine when it is supposed to be off.

The task manager may give you a clue when all programs are shut down.  If you can't find anything listed, it is possible you may need to contact customer support to get the machine swapped out.

    Sorry to hear that.

    In my case, I wanted to test another scenario so I disabled connected standby by changing the registry AND disabled fast startup.

    Shutting mine down at 67% and turning it on after some 15 hours later my battery was at 64%.

    So it didn't make a difference for me to disable CS and Fast Startup since with just the full shutdown I was losing about 4-5% per 24 hour of shutdown.

    At this point, I'm not sure if there's anything else we can do unfortunately....

    At this point, I believe doing the full shutdown is the only way to minimize the battery drain during shutdown.

    I just tried a full shutdown with that Device Manager setting change in place, and unfortunately in my case, it made absolutely no difference at all.  In a time span of almost 9 1/2 hours, the charge on my battery went from 87% before the full shutdown to 80% afterward (a 7% drop).
