Non-Vantage Way to Limit Battery Charging on X1 Extreme Gen 1?

I uninstalled Lenovo Vantage because of the recent terrible update that removed some useful features and added a bunch of adware-like features. There were only two major things I used it for anyway: driver updates and battery charge threshold. 

 

I can get updates easily with Lenovo System Update. However, I'm not sure if there's a way to instate a battery charging threshold on my Lenovo X1 Extreme without it. Anyone know of any way to do this without using Lenovo Vantage?

BTW: If you haven't done ti already, remember to uninstall also the SystemInterfaceFoundation driver from the Windows Device Manager, which is left behind by the Vantage Uninstall

Re: Non-Vantage Way to Limit Battery Charging on X1 Extreme Gen 1?

Thanks! Downloaded it, but it unfortunately doesn't seem to work for me. Invoking the app gives me a list of commands (as it should), but any other command (e.g. "status" or "on 60" or "off") gives no feedback from the command prompt.

And I tried unplugging my laptop and letting it discharge for a bit, but it does re-charge even though I set a limit using "on 60". So I don't think it's working.

I did uninstall System Interface Foundation and checked Device Manager to make sure it was gone. It was.

I also double-checked that Power Manager is installed in Device Manager. It is.

I also tried running this fix in the thread: https://forums.lenovo.com/t5/Lenovo-Vantage-Knowledge-Base/Q-amp-A-setting-a-ThinkPad-battery-charge.... Unfortunately didn't help.

Any advice would be appreciated.

This is how I use the tool (make sure you run it with administrator privileges):

 

To check the current status:  

ChargeThreshold status

 

To disable charging threshold (for when you travel or are unplugged a lot): 

ChargeThreshold off

 

To enable charging threshold (for when you are on AC for long periods of time) and set it to a min of 75% (below which it will start charging) and a max of 80% (above which it will stop charging): 

ChargeThreshold on 80 75

 

Remember that if you set a min threshold of, for example, 75% and your current battery level is above that you'll have to unplug and discharge the battery to below 75% for the charge threshold to take effect.

 

Hope this helps.

Re: Non-Vantage Way to Limit Battery Charging on X1 Extreme Gen 1?

Thanks! That's pretty much what I'm doing, but I'm not getting any reply from the program.

 

When I open a PowerShell with admin privileges, if I type:

.\ChargeThreshold.exe

I get the help info:

ChargeThreshold.exe, built on Jan  7 2019

    ChargeThreshold parameter [arguments]

Description:
    Get/Set Battery Charge Threshold.
    Lenovo Power Manager driver needs to be installed.

Parameter list:
    status  Show current setting.
    on      Enable Charge Threshold. See Examples for how to specify start and stop thresholds.
            Specifying a different value for dual batteries is not supported.
    off     Disable Charge Threshold to use battery default setting.

Examples:
    ChargeThreshold status
    ChargeThreshold off
    ChargeThreshold on 80            Stop:80%/Start:75% for all batteries.
    ChargeThreshold on 80 60         Stop:80%/Start:60% for all batteries.

However, if I type:

 .\ChargeThreshold.exe status

or 

 .\ChargeThreshold.exe on 90 85

I get no echo -- it just goes to the next command prompt line. 

 

I also tried setting the threshold to 90/85 as above after entering the command. I then drained the battery to around 80%, plugged it back in, and it went all the way back up to 100%.

Try with a regular Administrator Command Prompt (CMD.EXE)

Thanks for sticking with me and for the input. Unfortunately, no joy.

Same behavior (no echo for anything besides calling the exe with no modifiers). Set it to 90/85, drained to 80%, and charged back up, and it went to 100%.

Thank you for posting this. Just used it on my Yoga X1 gen II. Why it isn't a standard feature I'll never know. My battery is down to 40 Wh from 56 Wh and has hardly ever been used so this should help preserve what's left.

Hi Philo,

 

Copy Chargethreshold.exe to your C:\windows\sytem32 directory.

 

open your Notepad text editor create a new file on desktop and copy these lines into it.

 

@echo off
cd\
cd windows\system32
Chargethreshold.exe off

 

Then you save ase Limit OFF.bat       not .txt  but .bat 

 

Then you create a second one with these lines

 

@echo off
cd\
cd windows\system32
Chargethreshold.exe on 80

 

And you save on the desktop as Limit ON.bat

 

I am pretty sure they will run when you click 'em.

 

Ciao, Han

Thanks for the input, Han. The scripts indeed run when I click them, but they don't actually set a charge threshold; I tested one setting the threshold at 80, drained my battery and then plugged it back in, and it kept on charging to 100%.
