Adding Multitouch by a hardware replacement ?
So I thought of buying an topcase of a MacBook Pro 4,1 which has got a trackpad with multitouch for my MacBook Pro 3,1
Do you think it is possible, or will there be problems due to the flat ribbon cable or the connector or other hardware-related issues ?
Hmm added an early 2008 multi-Touch trackpad upper assembly to my late 2007 MacBook Pro with no issues ... have been enjoying my multi-Touch ever since ...
Update ... Very glad I could help, I forgot to mention about the keyboard function keys being different, I had to change a a couple of my keytops to reflect the changes, well worth the extra effort!
Here's my original post:
Unfortunately, Apple moved the connector to the left on the logic board in the 4,1 revision.
HOWEVER due to Erich's information, we were able to verify that there is sufficient play in the cable to connect and give the A1226 MacBook Pros multiPod Touch functionality using an A1260 upper case!
Please take this opportunity to upvote Erich's Answer as correct, as I have also done!
Not sure if anyone will still be reading this but her I go anyway:
I'm contemplating the same procedure, just wondering what if any adjustments I have to make to the ribbon cable on the 1260 topcase to make it connect easily and without straining it. Anything outside of simply unplugging the old one, plugging in the new one, and putting the screws back in. Thanks
Did this a while ago, so fuzzy on the details. As I recall the parts fit was the same. There are a couple of ribbon cables and "press-on" flat connectors (for those cables) that you need to take care not to dislodge.
Just move slowly. I recall the guide being very good.
(1) Get *good* screwdrivers. It's so easy to strip many of those small screws.
(2) The mod is very much worth doing, IMHO.
