FOCUS LCD New for MacBook Pro A1278 (2009, 2010, 2011, 2012 Year) (EMC 2326, 2351, 2419, 2555, 2554) Trackpad Touchpad with Flex Cable Replacement

Be Careful While Replacing TrackpadThis is where
I had the most problems: I just couldnt get the set depth right. If you screw it in too far then theres no give but too much means it doesnt work right either. I had to reassemble and disassemble three times to get this perfect. Something I wish I did before removing the old screw from the old top case was noting how far it was screwed in. taken a picture first so I knew how far to screw in the new T5 on the new top case. Dont make that mistake. While removing the four tiny screws, support the trackpad on the bottom with your fingers avoiding dropping off. Turning the screw counterclockwise will loosen the trackpad. Turning it clockwise will tighten the trackpad. Make sure all gaps between the trackpad and palm rest are equal.
