MacBook Pro 2009 15” Recovery Mode non existant OSX 10.5.8

I have a number of issues with a MacBook 2009 15” running Leopard.I wish to upgrade to El Capitan if possible. Do I alter the computer time and date so it corresponds with the download as I can remember from past experience on an iMac I had to do just that. I used Internet Recovery but Cmd+R or Cmd+Opt+R doesn't seem to show it just goes straight to the front login page, perhaps Leopard doesn't have that function. I don't have the original Leopard startup disks for this model only a 2009 MacBook 13” which probably won't work. If someone could give me a guide on what exactly I should do it would be most appreciated. Secondly, I have a blue/white vertical bar on the center left of the screen. It doesn't show up when I connect to an external monitor. MacBook Pro 2009 4 GB RAM
