versions. The `thinkpad_acpi` module was not loading, with the following

TODO: test on latest lbmk revisions, after the update to coreboot revisions
from February 2023 for Haswell boards. This issue was reported on Libreboot
20221214, which was based on a much older revision of coreboot for those
mainboards.
tlp
---
You can install the `tlp` package and start that service. For example, on
Debian:
```
apt-get install tlp tlp-rdw
systemctl enable tlp
systemctl start tlp
```
Now read the manual:
```
man tlp-stat
```
As root, you can do:
```
tlp-stat -b
```
This will provide information about the battery.
What other firmware exists outside of libreboot?
