If your battery has much lesser capacity or does not charge at certain level any longer, you may want to perform a gauge reset on it.
Note: make sure the AC adapter is plugged in when perfoming a gauge reset.
Go to Power Manager > Battery tab > Battery Maintenance
You should see this image - look for the Perform Reset button.
how can we improve it?

Is it true that we have to manually rearrange the power settings before we start the reset. The program asks us to close all the other applications, which means we should leave the computer alone on its own while it is doing the reset thing. I have tried this once: the computer goes into sleep mode after a while as my original power settings are not arrnaged. I have, then, put it into presentation mode and left it for the reset overnight, but it was again sleeping when I checked it in the morning and had not finished the reset. The reset is probably going to take 3-4 hours for an E220s; but for this to start and finish properly, you have to first manually change your power settings in such a way that nothing sleeps or hibernates. Is this true? If this is the case, how does the reset program not to do this very simple thing on its own?
Yes it's recommended not to do anything while the battery is undergoing this reset. I'm not sure what would happen if never follows the instructions but there should be a reason not to do so.
To avoid your machine goes to sleep/hibernate/shut down , you need to set your machines to 'do nothing'. If you have Lenovo ThinkVantage Power Manager installed, check out the settings there to ensure all are set to do nothing. Otherwise, check the windows power options.
I believe the reset program does not do it on your behalf to avoid changing some settings without users' notice. For example, i configurely the time to sleep, hibernate and shut off time differenlty in Power Manager. I do not like other software to mess up my settings.
I''m sorry if this has caused inconvenience to you. Hope that you got your issue resolved.
Please make a battery maintenance feature for windows xp!
I installed this system on lenovo s 205 and my battery does not fully charge! I cannot correct this!
Regardless Win XP or 7, the software is more or less the same.
This article is actually for Think products. Lenovo s205 does not use ThinkVantage Power Manager as showed above. Yours should be using Lenovo Energy Management which you can download from http://support.lenovo.com.
Your battery does not charge could be due to some settings in Energy Management. Please check this TKB article hopefully it helps. It mentions about resetting battery gauge, power settings, etc.
where can I find this "Power manager" ?
I have a thinkpad T430 S. I preferred installing xp sp3
The battery gauge seems to have a different behaviour if compared with other experiences of mine
after 6-8 months from the pc was bought, it appeared shutting down to early if compared with the duration estimated by the gauge
Indeed this behaviour may be understood, and the battery re-calibrated, but not so early, in my expereince
Indeed it was after 6-8 months, not possible to have a hybernation of sleeping planned -say- at 10% remaining of the battery duration, as the 10% could not be reached as the pc stopped far before
Thus I performed maintenance of the battery as explained in the starting post above
The battery maintenance was performed -of course- at night. The following morning I found the thinkpad switched off and no message appeared when turning it on.
The situation, in any case didn't change at all: the pc uses to switch off when the gauge says 2 hours remaining and, interesting, as soon as I connect it to the power, it start saying to be incredibly already charged at 70% !
May I have some idea about this case ?
- battery firmware or sw not suited for XP ?
- battery with some cell broken ?
- how to have more information about the gauge calibration (maintenance) without waiting hours in front of the pc
Bye and thanks
Hi, everyone!Does the battery gauge reset indicate when it finishes? I started it almost 20 hours ago, now Power Manager says the battery's at 100% and the geuge reset icon is stil on, and says it's still running. What am I to do of this?
I am using U410 ideapad, i had set my battery to charge at 60% only, now i want to full charge it to 100%.
There is a software but can't remember how to activate it.
I have the exactly the same issue. Lenovo staff, please do help!!
Here are some additional things to consider:
1) Check for availability of battery firmware updates on the Lenovo support site - these should be available under download section for your particular system model if one is available.
2) Be sure you are at the latest BIOS version as BIOS updates can also carry updates for the Embedded Controller (EC) which affects many aspect of system operation.
3) Check for latest version of power management software. If battery is only charging to 58%-60%, the battery may be set to lifespan mode. Refer to settings in power manager to set to full charge.
4) If system shuts off before showing below 10%, the battery reset may need to be run to re-learn the full charge capability. If the battery will not reset properly, it may need to be replaced. Sudden drops in run time during operation can be a sign that a cell is going bad in the battery pack.
Whats crazy about my system is I did a complete driver update with the lenovo update and I still dont have the option for Automatically optimize for battery lifespan. It never shows in my options please someone help me to get this option so I wont burn out my battery. Here is the link to my screen shot http://screencast.com/t/aOvXEJfLnmSm thank you
i have lenovo Z510 with windows 10.. i am not able to find battery gauge option.can u help me in this
In what app or where is the option to perform a battery gauge reset?!? I have a Y50-70 machine and I remember that this option was present in one of the Lenovo apps preinstalled on Windows 8.1. I even performed the battery gauge reset once. I have switched to Windows 10 more than two years ago and now the only application that is offered for system related tuning and options is Lenovo Companion where these options illustrated above are missing
Hello I am using a Ideapad P400 touch and I have the energy managment app up and the battery guage, how log is it gonna take and can I have it closed?
