+@subsubsection Power management Services
+
+@cindex power management with TLP
+The @code{(gnu services pm)} module provides a Guix service definition
+for the Linux power management tool TLP.
+
+TLP enables various powersaving modes in userspace and kernel.
+Contrary to @code{upower-service}, it is not a passive,
+monitoring tool, as it will apply custom settings each time a new power
+source is detected. More information can be found at
+@uref{http://linrunner.de/en/tlp/tlp.html, TLP home page}.
+
+@deffn {Scheme Variable} tlp-service-type
+The service type for the TLP tool. Its value should be a valid
+TLP configuration (see below). For example:
+@example
+(service tlp-service-type (tlp-configuration))
+@end example
+@end deffn
+
+By default TLP does not need much configuration but most TLP parameters
+can be tweaked using @code{tlp-configuration}.
+
+Each parameter definition is preceded by its type; for example,
+@samp{boolean foo} indicates that the @code{foo} parameter
+should be specified as a boolean. Types starting with
+@code{maybe-} denote parameters that won't show up in TLP config file
+when their value is @code{'disabled}.
+
+@c The following documentation was initially generated by
+@c (generate-tlp-documentation) in (gnu services pm). Manually maintained
+@c documentation is better, so we shouldn't hesitate to edit below as
+@c needed. However if the change you want to make to this documentation
+@c can be done in an automated way, it's probably easier to change
+@c (generate-documentation) than to make it below and have to deal with
+@c the churn as TLP updates.
