I have a Y570 and the only problem is it doesn't switch back to Best battery health when it gets plugged in.

Re: Changing Default Energy Management Options...

@All,

Engineering weren't able to replicate the issue. He is asking if you remove the battery after the laptop has been shut down?

Their notes as follows.
"I tested with the Y570 with WEB bios level 47CN25WW and with PWR MGR 6.0.2.0

I have set the MGR to Best Battery Health. I restarted, shut down put it into stand by and hibernation and the setting is still the same.

The only time the PWR MGR looses the setting is when I re-seat the battery. Just a replug of the battery and thats enough to by back at the Battery runtime setting
"

@ Jamez

 

Jamez the problem occured when i shutdown and moving the notebook. For example, when i work in the office i set best battery health. When i go home and i turn on the laptop the setting going back to optimize for battery runtime. and that was a problem to me because what if someday i forgot to change, the lifetime of battery will reduce right?

 

One of my friend just bought a lenovo z360, when she choose the option for best battery health, it never change when you go home or go to office until she changed it manually. the question is why i can't do that in lenovo Y470?

I'm sorry i forgot to mention that i'm shutdown and turning off the notebook and then i unplug the cord without doing anything to the battery. At home i plug the cord and then i turn on the notebook again without doing anything to the battery.

hope this clear.

I don't remove battery after I shut notebook down. If I did and that was the problem, I think I won't have any questions. In my case, there're two things needed to reset battery setting to optimized runtime - notebook has to be shut down and there should be no external power supply. As soon as two these conditions are fulfilled, that battery setting resets immediately. As I understand, ferdynandus has exactly the same problem, and the others in this topic as well.

@JameZ,

 

This is how I run into the issue:

•Notice battery is charging past half, change power management to battery health.

•Unplug the laptop - power management is still set to battery health.

•Battery has dropped to at 35% - power management changed to Optimize for Battery Runtime by itself.

•Plug the laptop in - power management still set to battery run time. 

 

From here, the laptop will continue to charge completely unless manually changed. Power management does not switch back to battery health, even after reaching 50%.

 

If I remember, I can immediatly switch it to battery health when I plug it in and it will charge to 50%. 

 

Hope this helps
