Upgrade done. It is hard to connect the lcd to the motherboard (step 10). The first time I didn’t do it well and when turn on the computer, the display doens’t show nothing and the vents run like crazy. I turn off, connect again the connector (step 10) and all run well! Five star to this guide.

I am also installing the upgrade kit. Do you already know where does the usb cable get plugged in and if it is necessary to remove Bluetooth card? Thank you!
