L380 Yoga battery draining in hibernate mode

Hi,

 

I'm having issues with my Thinkpad L380 Yoga. The battery loses approx. 8% overnight, when its in hibernate mode.

Any suggestions how to solve this? Is this a software error or hardware?

 

I already turned off all wake timers, windows fast startup, powered USB-port when off, wake on lan etc.

Updated all drivers, tried previous BIOS v.1.18.

 

Also turned off the chariging treshold in Lenovo Vantage, as I read it could cause the problem.

 

Cheers,

Jannik

Re:

Hi, Thanks for reaching out. During hibernation, some power is usually still routed to peripherals so that you can, say, tap your keyboard and have the PC boot this will cause your battery to still drain but a bit slower than when on a powered on state. This could explain the battery drain during hibernation but it shouldn’t be that much.

 

I did a quick search and found similar issues on other models (see links below) and it appears that the issue is software and the fix is a BIOS update. At this time, we recommend running the Lenovo Vantage app from time to time to check for the latest BIOS for your computer.
