Lenovo T-460S - battery draining during suspend

dejy · 2017-03-15 12:32:38

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

How are you measuring power usage during suspend?

buzo · 2018-02-14 15:37:59

Did you make any progress on this problem? I'm asking because I am facing the same annoyance with a T-470S.

R00KIE · 2018-02-14 16:33:54

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.

buzo · 2018-02-14 21:10:37

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.

Same issue here with a Lenovo T460s, both trying to suspend on a freshly install Xubuntu and 'normal' Ubuntu 24: can not wake the laptop up again once suspended.

The previous OS, an Xubuntu 20, worked without any problems, and easily wakes up after an suspend by a simple keystroke (or when opening the lid).

Adding to this, the power button changes behaviors, and will not work once the new ubuntus 24 has done a normal shutdown: I will not work anymore, only solution is to press the power for 5 to 10 seconds for a full PC reset and then it works normally again..

Finally, a normal shutdown on the new ubuntus 24 seem not to shutdown fully, and battery gets drained, eventhough the PC seem to be fully powered off.

Disabling the security chip in the bios (F1 | Security | Disable Security ..etc as above) cured everything: now suspend/re-wakeup works in Xubuntu 2024, the power button behaves normally, and no battery drain is seen when fully powered down!

Oh boy.
Firstly, *buntu is not supported here as stated in the rules you just agreed to when registering.
Secondly, don't necrobump.
Closing.
