title: Why there is reset button to desktop computer but not for laptop
body: <p>The main question is how reset button from the desktop computer works. How processor deals with reset button hardware interrupt.</p>
  
  <p>And Why there is need of reset buttons to computer.</p>
  
  <p>if so </p>
  
  <p>then Why laptop computer does not have reset button.</p>
  
  <p>Again...
  please tell me How processor deals with reset button press interrupt even when computer is in " hang " position.</p>
  
  <p>if computer(processor) is in hang condition means processor is overloaded with processes and it can not process tasks now then how he can handle or process on reset interrupt. </p>
  
  <p>thanks </p>
