Lenovo T-460S - battery draining during suspend
I'm using a Lenovo T-460S - on suspend the battery drains ~15% per 12 hours. Not sure how to profile this?

Re: Lenovo T-460S - battery draining during suspend
How are you measuring power usage during suspend?

Re: Lenovo T-460S - battery draining during suspend
Did you make any progress on this problem? I'm asking because I am facing the same annoyance with a T-470S.

Re: Lenovo T-460S - battery draining during suspend
Suspend needs to use battery to keep the ram state, there might also be other things using battery such as wake-on-lan active for the ethernet port, I would say that some usb devices might also still be receiving power.

Re: Lenovo T-460S - battery draining during suspend
Sure, I already deactivated everything in the BIOS like wake-on-lan, but still the battery loses 50% or more overnight when in sleep mode. I need to shut it down completely because of that.
Maybe it is a Thinkpad-only problem, that's why I bumped this thread.
