Re: Battery Charge Threshold bug - charges past threshold

@hzfdbd, This morning I uninstalled/reinstalled the Lenovo Vantage app.  I then ran a system update.  There was a new BIOS update as well as an update for my docking station so hopefully the combination of things will solve my issue.  Will let you know.  Right now I'm running R07ET83W 2.23.  And I have an Ultra Dock.

 

FYI: I just opened the Vantage app and the Battery Charge Threshold setting was disabled.  It was enabled this morning.  The only thing that I can think of is that the Windows 10 Spring Creators Update (1803) - which I installed today - somehow disabled it.  I've enabled it again so we'll see what happens.  But the setting doesn't appear to stay enabled.  Something seems to be causing it to disabled itself.

Re: Battery Charge Threshold bug - charges past threshold

@anthonyw22, I tested my system with basic dock after 1 night. It is working. Is your system with dual batteries?

Re: Battery Charge Threshold bug - charges past threshold

@hzfdbd: No, single battery.  Since I updated the BIOS and docking station everything seems to be working.  Just tested it with sleep so far.  Over the weekend, I'll test it a bit more but so far so good.

Re: Battery Charge Threshold bug - charges past threshold

@hzfdbd: Just wanted to report back... so my battery charge threshold seems to be working correctly now.  I think one or both of updating my system (BIOS and docking station updates) and reinstalling the Vantage app did the trick.  Thanks for your assistance.

Re: Battery Charge Threshold bug - charges past threshold

Sorry hzfdbf,

 

I didn't realize there already was an active thread about this. Can delete/ignore the other one.

 

We tried on one to reinstall Windows 10, updating it fully, then Lenovo Vantage and updating everything there, and then setting threshold however it didn't help. It charged when shut down and randomly added 1% here and there sometimes when on.

 

BIOS: R0RET30W 1.13
Machine Type: ThinkPad L380 Yoga
Product Number: 20M7CTO1WW

 

Thanks for the help.

Re: Battery Charge Threshold bug - charges past threshold

I got the over charging issue on my L380, too. I recognize that, no matter the system start up or not, if I unplugge the Type-C charger and plugge it back, the battery charging thresholds setting will not function normally. Even though the battery message in both Windows 10 and Lenovo vantage shows "plugged in not charging", the system still slowly charge the battery till 100%. The only way to solve the problem is to open Lenovo vantage and restart the battery charging thresholds. 

 

Windows 10 1803 

Lenovo vantage version is 4.13.82.0

BIOS version is R0RET30W 1.13

all drivers are up-to-date

By the way, I tried to contect Lenovo supports. At the first time, they just send me an e-mail with some download links of BIOS and driver installation files, and told me to update those what I have already told them is up-to-date. Obviously, after reinstalled the BIOS and all other drivers, the charging thresholds issue is still hanging there. They asked me to send the machine back to have some test.

 

It seems like not just me having the battery charging thresholds issue, so it is possible for their engineers to reproduce the issue and try to find out the bug or the "Design defect".But I just got the reply from Lenovo telling me that their engineer tried to set the charging thresholds at 90%, and no matter plugge in or out the Type-C charger, battery charging thresholds functioned properly, and asked me to send the machine back to have some test again.

Re: Battery Charge Threshold bug - charges past threshold

 @Oscar1929 

 

The fact that they asked you to send it back is imho terrible. We're in the same situation having brand new L380 Yoga's charging past the thresholds and sending them back so they can take their time and see if they can fix it is not feasible. 

 

I hope @hzfdbd can come up with something.
