Yes. I should have included that.
Thank you so much lol
You taught me that i didn’t have to throw and break this darn machine to get the hard drive out :P

Thank you!
This guide works well for the 4320s as well, though there are a few small differences.
The battery compartment has 4 screws and there are none on the back.
The keyboard is held by 4 screws.
The touchpad has the same type of connector as the keyboard.
The hard drive cage is held by a #1 Philips and two #0 Philips instead of #1.
Thank you kindly for such a easy to follow step by step tutorial. Never thought this rooky would be able to repair my own laptop
You guys rock
