Hi

Does anyone know of a way to recalibrate the battery on a ThinkPad laptop under CentOS Stream 8?

I did this on the same machine before, but I can’t recall exactly how. And maybe I was on CentOS 7 at the time. I know about the “tlp” command, but I haven’t had much luck with it so far, as shown here:

$ sudo tlp recalibrate BAT1
Setting temporary charge thresholds for BAT1:
start = 96 (no change)
stop = 100 (no change)
Error: battery discharge/recalibrate not available.

Also, “tlp-stat” says (after displaying status values etc.)

+++ Recommendations
* Install acpi_call kernel module for ThinkPad battery recalibration

I can’t seem to find an easy way to install the module in question, though.

I also seem to remember that there was a different tool as well, but I’ve forgotten its name, and a web search returns little of use…

Any ideas?
