[QUOTE="techiesteve, post: 1842846, member: 98520"] Going back to your first post, re 'little bit of corrosion on the wire' and 'didn't look too bad'. The 'wire' must be the IPD flex cable, and I only find the cables contacts show corrosion when there has been a previous liquid spill. Unless after your cleaning the cables contacts are spotless, there will still be problems. I find the IPD flex cables are a high failure part anyway, and replacement in cases such as yours advised. In the older MBA's the keyboard data enters the trackpad, then with the trackpad data connects to the logic board via the IPD cable. Other than the logic board and trackpad that you have replaced, the IPD cable is the only component that can effect both the keyboard and trackpad. Other issues can be if the lock bar has been broken off on the sockets at either end of the IPD cable. I won't get involved with the ASD issues, as even though now very old, I haven't used for a long time, and that is Apple proprietary software. It may be downloadable via torrents, but that doesn't make it legal. AASP's use AST and AST2 servers now for diagnostics. [/QUOTE]
