T420s discharging battery while power off

[Castus]

Hi!
I have T420s with ID: 417173G. There is a problem: when machine is fully power off (not hybernate or sleep mode), main battery is discharged -35% after 72 hours. Does it's a normal?

Do you have a fingerprint reader?

Check the global setting in the powermanager, whether "Activate USB permanently" is marked. - Disable it.

Yes. And green light is on, when power off. But -35% for green LED?!

"Disabled" always - not needed for me...

Hi Cactus,

Did you finally get the response to this and found how to fix the problem?
I have the same, also no permanent USB and rolled off all biometrics, but still the same -it looses about 20% a day
