+\begin{itemize}
+  \item Do not remove power abruptly:
+  \begin{itemize}
+     \item Boards components have been damaged by removing the power or
+           USB cable in an abrupt way, not leaving the PMIC the time to
+           switch off the components in a clean way. See
+           \url{http://bit.ly/1FWHNZi}
+     \item Reboot (\code{reboot}) or shutdown (\code{halt}) the board
+	   in software when Linux is running.
+     \item You can also press the \code{RESET} button to reset and
+	   reboot.
+     \item When there is no software way, you can also switch off
+	   the board by pressing the \code{POWER} button for 8 seconds.
+  \end{itemize}
+  \item Do not leave your power board on a metallic surface (like a
+        laptop with a metal finish).
