"Keyboard and trackpad don't work, loose cable?" için yanıtAll I had to do was order a $7 USD trackpad cable from Amazon and install it myself. It’s easy to install. Just unscrew the back casing (you do need a special screwdriver that can also be bought on Amazon for a few bucks). The cable itself just plugs in after unscrewing a couple small screws holding it in place. The 3rd-party vendor cable that Apple installed in many Macbook Pros were crap. Has been working fine for 2 years now with the new cable. Start with replacing the cheap cable. The repair shops will tell you that the keyboard and trackpad components need to be replaced or that your motherboard is dead. They just want to make money, or they are too lazy or incompetent to do a proper diagnostic. In some cases, Apple requires Authorized Resellers to replace complete component units rather than just the minor failing part. Don’t listen to those that make this sound complicated; it’s not!
"Trackpad and keyboard not working, tried fix, other suggestions?" için yanıtI don't recommend http://www.powerbookmedic.com/ .... They are charging $54 for a new trackpad cable .... you can get these on ebay for $10-15 new. This site is too overpriced. Shop around.
"Keyboard and trackpad don't work, loose cable?" için yanıtI have this same problem which surfaced just a bit over the 1-year warranty period. Keyboard and trackpad do not boot up and hence can't log in. Then all of a sudden, after a couple frustrating months of using a bluetooth keyboard and a USB mouse, everything started working again. That lasted 3 months. Then back to no keyboard and no trackpad. On a whim, I turned by Macbook over and gently but firmly pressed back and forth on the underside of the laptop in the proximity of the trackpad ... and now it works ... but I have to do this every time to get things working. I thought maybe the trackpad cable was loose, so I finally got ahold of a pentalobe screwdriver (impossible to find outside of the USA). I tried snugging up the cable which looked firmly seated at both ends. Alas the problem continues .... still rubbing the bottom of my expensive 2015 MacBook Pro just to get it to fire up correctly. Perhaps massaging the laptop's underside flattens out any swelling in the battery ... or it nudges the trackpad...
