How can we tell if the digitizer is defective?

I also had my screen replaced due to ghosting just this week. Now that you mentioned it, the pen doesn't drift anymore towards the edges (even the bottom edge). Cool .)

yes, though sadly that was the ONLY thing they managed to fix. the ghosting, wifi issues, bluetooth issues, and finnicky USB ports still remained.

if you've warrantied your laptop 3/4 times I highly suggest you file a formal complaint...lenovo is pretty good about that
