+General information like which GPE is assigned to the EC and whether

+or writing to them.
+
+CAUTION: Do not write to the Embedded Controller if you don't know
+what you are doing! Rebooting afterwards also is a good idea.
+This can influence the way your machine is cooled and fans may
+not get switched on again after you did a wrong write.
