My old Toshiba chromebook B3340 died. I mean completely dead. I orded two Toshiba chromebooks reconditioned and neither one had the hi-res screen like my old one. I returned both. So that left me to repair my old one. I found a youtube on how to replace mother and daughter boards to bring it back to life. I carefully removed the old mother and daughter boards and installed the new ones. Success the Toshiba chromebook B3340 came back to life with it's hi-res screen. This is a great chromebook worth the effort.
