Go to SolutionLatitude 7400 battery drain after shutdown
Hi Dell Community,
Recently I bought a Dell Latitude 7400.
I am having issues with the battery duration.
I started seeing that after a Windows Shutdown (battery charged to 100%), then the day after in the morning the battery remaining capacity was about 78-79%. When I don't shutdown the laptop and I use the "suspend/sleep" mode, then the day after the battery is about 94% (I think this is reasonably fine). So, something is wrong with the battery only when the computer is powered off with the "Shutdown" from Windows).
Recently the BIOS was upgraded to the latest version. Prior to this update the battery when "Shutdown" (the day after the shutdown) was 89-90%, after the BIOS upgrade I have the same problem but with battery about 78-79%.
I have tried to shutdown Windows using "full shutdown" (pressing the shift key while pressing the button of the windows menu to shutdown), tried to disable the Windows "Quick Start".
Seems that the energy management from battery is far better using "sleep/suspend" (so, Windows Modern Standby) than using a normal "Shutdown".
I don't think this is a battery issue, if it was then the battery drain should be more or less equal in both scenarios (I think). I don't know if BIOS is doing something when powered off, or if some device is not completely/properly powered off and it remains raining the battery capacity.
Any ideas?
Thanks in advance.

Same problem here. Battery drains overnight about 15% when shut down and unplugged, but drains more slowly when in 'sleep' mode.

I have had this problem on virtually all brands of laptops that I have owned EXCEPT the Apple machines.
My HP x360 was horrible.
I use Hibernate (never sleep as I don't trust Windows to stay asleep). Although I have not experimented with battery drain on my 7400, I would give that a shot. Hibernate works great if you have 16GB or less. Once you have more, I don't like waiting for the wake up.

Hi @Rhyalus, just to clearify this: I shutdown the laptop completely by the start menu, no sleep, no hibernate. Battery indicator shows 100%. When I start up the laptop again the next morning, it has lost 10 to 15% of its battery charge. It does not happen ervery shutdown, but every third one.
Finally, after some time with this issue, I have no solution for it.
Seems something related to BIOS software.
In my case, sometimes when I shutdown completely the laptop, and some time later I power it on again the battery is showing 79%, 80-81%, 85%... then if I plug the AC adapter, after 5 to 10 minutes then the battery indicator in Windows (or watching it while charging inside the BIOS) shows 100% "battery fully charged", so I suspect the battery really has nearly 100% of the charge but seems BIOS/Windows is showing lower percentage of charge.
If I use sleep (Windows Modern Standby) / suspend then the battery/system works as expected (the battery indicator shows the correct capacity, small battery drain, and normal due to the sleep).

same problem for same laptop latitude 7400 2in1 . tried EVERYTHING but cannot fix. battery seems to drain after shutdown 10-20% (thats is maybe not real but it must be fix anyway). Maybe a bios update can fix this, DELL is listening?? It is a 2K $ laptop

Guys can you report your exact model, bios version and if you have powershare enabled and what type of battery you have, how much battery is gone after lets say 1, 3 and 5 hours after charing to 100% and shutting down? Maybe we will narrow down the conditions in which that happens.

A little kick on this subject. I have been in touch with Dell support. My battery drained from 91 to 77% overnight in just little over 9 hours while it was switched off. This is not normal behaviour, but Dell does think so:
Thank you for staying connected I appreciate your patience I was able to review the Battery report and it is working as expected as there is the degradation of the battery over the period of the system usage, which is expected.
This is unacceptable for me for such an expensive device.
Update = DELL-Cares setup a battery replacement.
