<title>Why does my computer not turn back on after I suspended it?</title>

<p>If you <link xref="power-suspend">suspend</link> your computer, then try to
resume it, you may find that it does not work as you expected. This could be
because suspend is not supported properly by your hardware.</p>

<section id="resume">
  <title>My computer is suspended and is not resuming</title>
  <p>If you suspend your computer and then press a key or click the mouse, it
  should wake up and display a screen asking for your password. If this does
  not happen, try pressing the power button (do not hold it in, just press it
  once).</p>
  <p>If this still does not help, make sure that your computer's monitor is
  switched on and try pressing a key on the keyboard again.</p>
  <p>Come ultima risorsa, spegnere il computer tenendo premuto il tasto di accensione per 5-10 secondi, anche se così si perderà tutto il lavoro non salvato. Eseguita questa azione, dovrebbe essere possibile riaccendere normalmente il computer.</p>
  <p>Se questo accade ogni volta che il computer entra in sospensione, significa che tale caratteristica non funziona con le componenti hardware presenti.</p>
  <note style="warning">
    <p>If your computer loses power and does not have an alternative power
    supply (such as a working battery), it will switch off.</p>
  </note>

<section id="hardware">
  <title>My wireless connection (or other hardware) does not work when I wake
  up my computer</title>
  <p>If you suspend your computer and then resume it again, you
  may find that your internet connection, mouse, or some other device does not
  work properly. This could be because the driver for the device does not
  properly support suspend. This is a <link xref="hardware-driver">problem with the driver</link> and not the device
  itself.</p>
  <p>Se il dispositivo ha un interruttore di alimentazione, provare a spegnerlo e a riaccenderlo: in molti casi, il dispositivo funzionerà di nuovo. Se la connessione è via cavo USB o simili, scollegare il dispositivo e ricollegarlo nuovamente per vedere se funziona.</p>
  <p>If you cannot turn off or unplug the device, or if this does not work, you
  may need to restart your computer for the device to start working again.</p>
