+== Battery drain when sleeping ==
+
+The laptop uses the S2 sleep mode by default instead of S3, which leads to
+draining a lot of battery during sleep.
+
+Though this is intentional by the manufacturer and might cause lockups when
+forced  I - @moredread - never had any issues with it.
+
+See https://wiki.archlinux.org/index.php/Dell_XPS_13_(9370)#Power_Management
