5. Click> Preferences
6. A dialogue box with 3 Tabs will open.
   Tab 1. Running on AC
   Fig 3
   
   
   Here you can by means of sliders alter Sleep time and Brightness.
   In the Actions section the default is Blank screen when lid is closed.
   This is OK but from a power saving point of view perhaps suspend.
   
   Tab 2. Running on Battery
   Fig 4
   
   
   This has similar controls but as you can see the settings are lower.
   The Actions are set at Suspend by default

   This is not always the best selection perhaps better to use Hibernate.
   As those of us who close the lid and put machine in our bag may find it can overheat.
   
   Tab 3. General
   Allows More personal preference settings.
   Such as Sleep Type and settings for Battery Icon
   
   Click> Information
   A dialogue box will open with 4 Tabs.

   Options are as follows:
   

• Tab 1 Device Information
  This gives Information on batteries and allows the user to keep an eye on the battery state.
  As this is somewhat technical information user is advised to consult the Help at bottom left.
  
• Tab 2 Charge History
  This is a graphical view showing battery percentage over time.
  
• Tab 3 power History
  This is a graphical view showing Charge and discharge over time.
  
• Tab 4 Estimated Time History
  This is a graphical view showing battery time till charged/discharged.

  All this information can be useful in diagnosing battery problems.
