+
+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?
