Changing Battery Charge Thresholds in IBM X32

[proaudioguy]

What is odd to me is that the OLDER of the 2 batteries has the menu item. I don't know what to think of that. Is there a way to update the firmware of the BATTERY?

proaudioguy... If I understand You properly You have 2 batteries for x32.. and one of them working with custom battery charge Threshold and the other not?

Yes?

Here's some more information - which confuses the picture even more

I removed the Battery Maximiser utility and installed the Thinkpad Power Manager software on my T42P. Surprisingly it works so the firmware must be compatible, even though it is not listed on the download page.

The Power Manager let me adjust the charging thresholds on my battery (genuine IBM FRU 92P1087). I then swapped batteries, to a generic non OEM one manufactured by BND, and the charging threshholds still work.

So, at least for the T42P, the functionality does not seem to be tied to battery as it is unlikely that BND would have access to any Thinkpad specific battery firmware.
