Install steps: https://en.opensuse.org/HCL:ThinkpadX13s#ISO_Installation Symptom: When booting to the installed tumbleweed, the battery percentage is not able to be measured so it always shows 0% (See attached screenshot). In the meanwhile, the readings dumped by the 'upower' command are all zero. -- You are receiving this mail because: You are the assignee for the bug.

By tracing the QCOM battery driver [qcom_battmgr.c], I realized that the qcom_battmgr driver needs a notification from the pdr_interface in order to activate the battery measurement, which should be the way originated from the Android systems running on Qualcomm's mobile application processors.

The same approach can also be seen in other distros, such as Debian and Fedora. -- You are receiving this mail because: You are the assignee for the bug.

You can add a proper "Supplements" tag to the package, so that it can be automatically installed for the target hardware. -- You are receiving this mail because: You are the assignee for the bug.

Thanks for the suggestion. I have submitted packages with a "Supplements" tag in the "pd-mapper.spec".
