          Appeal No. 96-2444                                                          
          Application 08/360,194                                                      

          switch to perform the functions of the normal mode/standby                  
          mode switch and the case-closed switch, which has not been                  
          established, some way of distinguishing between the different               
          modes would have to be provided.  However, the examiner does                
          not explain why one of ordinary skill in the art would have                 
          been led to use the particular time-dependency technique                    
          claimed.  In our opinion, the examiner has failed to establish              
          a prima facie case of obviousness with respect to switching                 
          between modes depending on the time period the switch is                    
          depressed, which limitations appears in various forms in all                
          claims.  The rejection of claims 1-38 is reversed for this                  
          additional reason.                                                          

          Appellants' arguments                                                       
               Although we reverse the examiner's rejection, we note our              
          disagreement with appellants' arguments regarding the sleep                 
          function.                                                                   
               Appellants' argue (Br9-10):                                            
               Applicant has acknowledged a case closed detector which                
               senses whether the case is closed for sounding an alarm                
               to the user.  However, in such circumstances, the user                 
               has a responsibility to respond to the alarm and to act                
               in accordance with good computer practice by opening the               
               computer, toggling the computer to a standby mode and                  
               closing the computer.  Opening and closing the case with               
                                       - 13 -
