Surface Pro 4 battery drain while OFF

Anonymous

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.

Hi all,

Have any one of you felt the back of the surface is keep warming even after shut down after many hours? Only after the battery drain empty the part turn to cold. I suspect it cause the battery drain on my devices. I have tried to use normal shutdown, button force shut down, cmd shutdown, all end up the same situation.

About 6 1/2 hours after I started up the SP4, it reported the battery charge at 100%. I then reran this same test (again not restarting Windows), but this time the battery charge at 95% going into hibernation. 7 hours later, the battery charge was at 89%.

I'm now once again running a test in which I am changing the Device Manager component setting back to what it originally was by default, then restarting Windows, then again implementing the Device Manager component setting change, then restarting Windows, then going into hibernation, but this time, the charge is at 87% going into hibernation.

6 hours later, the charge is at 82%. So the Device Manager setting change truly didn't make a difference at all. When I ran these tests with the battery at 100%, I was really hopeful that there might be a possible resolution to this. It turns out that what I tried isn't a resolution at all.

Never mind. Valient attempt! I got really excited for 24hrs!

nope... I only use the button to power it on. The rest of your questions is old news.... keyboard or no keyboard... same results... It will take some time... but you need to read this WHOLE thread.

Thanks
