I have a W540 with Windows 7. Most of time (99%) I am using the power supply. I want to make my battery last longer. In the Power Manager tool, I click the Battery Maintenance ... button and get a dialog which tells me there is a Battery Health Mode I can use to increase the battery lifespan (the dialog's picture is attahed).
My issue is I cannot find where that Battery Health Mode is? Anybody can help me about this?
In my case, 99% on power supply, should I take the battery off and store it somewhere? But I would like to keep it installed because it can save my work when the power get off suddenly sometimes.

I'm not 100% sure but it might have been removed. In the past there was a radio button between fully charge and custom charge that gave you that option.
Regardless you can use custom charge threshold to accomplish same thing. If I remember correctly it basically reduced the max charge to 90%.
If its always plugged in you can set charging threshold at maybe to stop charging at 60% and start at 40% ? See below post.

I think you may want to read this article: https://www.techrasta.com/2015/01/how-to-increase-lifespan-of-thinkpad.html. It recommends to use Power Manager, which you can download here - https://support.lenovo.com/us/en/downloads/ds014924.

In my W30 (W7) I've tried to install Lenovo Power Manager 6.68.15 (n1au415w.exe, 18MiB) and got very serious problem. Computer started endless loop: Startup Repair has found problems. It will fix them automatically. Restart... Then Startup Repair could not fix the problems... And there is no way to end that loop...
The only solution was to restore C: image made earlier by Macrium Reflect Free edition.
I'd like to set threshold for my battery, as I use it on AC almost all the time,, but after that experience I'm afraid to install it again...

I use Lenovo Power Manager 6.68.15 on T530 with W7/ Nvidia graphics and it works as advertised. You can select "Automaticall optimize for battery lifespan". I doubt your problems are caused by the power manager. I would rather suspect a HDD with bad sectors.

My problems ware caused by Power Manger's setup (not by Power Manager itself) that created the endless loop.
SSD doesn't have any problems with bad sectors. It's confirmed by checking it and by successful run OS after restoring its backup.

No, I did not. I'm afraid of repeating the same bad experience again...

No, not at all. This is the first time I experience something like this

I have the same Power Manager installed on my two W540. I cannot find there is the "Automatically optimize for battery lifespan" option. Could you please tell me the steps to reach there?
