          }
      }); 
    }
  });
</script>

You are not sending any parameters for $this->input->get() to pick up on.

If you are just sending a GET request, you won't need to send a csrf_token like someone mentioned in the comments.

---

You may need to check/set a few config variable's first. These are in application/config/config.php

$config['uri_protocol'] = 'QUERY_STRING'; // OR AUTO
$config['allow_get_array'] = TRUE;
$config['enable_query_strings'] = TRUE;

---

var BASEHREF = "<?php echo base_url();?>";

---

Your ajax options should then include the following

{
   url  : BASEHREF + 'check/laptops',
   type : 'GET',
   data : { name : 'toshiba', price : '1000'}
}
// GET http://yoursite.com/check/laptops?name=toshiba&price=1000
