Answer 1

Use single and double quotes properly. Try this

$(document).ready( function() {
    var myspan1 = $("span[title='Laptop']");
    myspan1.append("<a target='_blank' style='vertical-align:middle;color:#0072c6'  href='@http://doc/IT/IT%20Library/SP_UAT%20Server%20and%20Services%20Error.PNG'> <b>[Show]</b></a>");
});

Answer 2

You have a serious problems with your quotes (mixing single and doubles, even unrecognized characters). Take a look to this:

 $(document).ready( function() {
  var myspan1 = $("span[title=’Laptop’]");
  myspan1.append("<a target='_blank' style='vertical-align:middle; color:#0072c6'  href='@http://doc/IT/IT%20Library/SP_UAT%20Server%20and%20Services%20Error.PNG'> <b>[Show]</b></a>");
 });

Answer 3

Your selector has problem with quotes Check this fiddle

$(document).ready( function() {
  var myspan1 = $('span[title="Laptop"]');
  myspan1.append("<a target='_blank' style='vertical-align:middle; color:#0072c6'  href='@http://doc/IT/IT%20Library/SP_UAT%20Server%20and%20Services%20Error.PNG'> <b>[Show]</b></a>");
 });
