+= Dell XPS 13 9300 =
+
+== Firmware upgrades ==
+
+Note that this device is supported by [https://fwupd.org/ fwupd].
+To perform firmware upgrades just activate the service
+
+<code>
+services.fwupd.enable = true;
+</code>
+
+Then use <code>fwupdmgr</code> to perform updates.
+
+== 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.
+
+See https://wiki.archlinux.org/index.php/Dell_XPS_13_(9300)#Power_Management
+and https://bugzilla.kernel.org/show_bug.cgi?id=199689#c3 for reference
