Chosen Solution
Hi everyone! Sorry for my english. Hope you understand. I have an A1342 Macbook White. It was working fine, but I decided to install an SSD drive. After that, I’m having an strange SMC problem. OS X (El Capitan) install was succesful, but Macbook’s only way to boot up is holding the power button for almost 15 seconds. Magsafe led’s green. Led light indicator goes crazy : blinking, smoothing, etc. When it finally power up, fan speed is really high, battery is not detected, and system runs very slow. I’ve tried installing again the original HDD, but nothing happened. I already had this problem whit another A1342, and resetting the SMC solved it. But… When I try to reset the SMC in this Macbook, it just doesn’t do anything! Doesn’t even try to boot whit the reset SMC’s keyboard combination pressed. If I keep pressed the power button, it “starts” to boot, but, if I press the combination, it inmediatly power off. Any answer will be useful! Thanks, and sorry again for my english.
The SSD is compatible as it auto senses the systems SATA port which is SATA II (3.0 Gb/s). So thats not an issue here. I’m suspecting the drive cable might have gotten damaged. Do you have access to a second Mac system which you can connect to this one and then put the system into target mode? If you can try running Disk Utilities First Aid to see if the drive is OK (it makes no difference which drive you have installed here). If the drive comes back with errors then I would replace the cable. Here’s the IFIXIT guide: MacBook Unibody Model A1342 Hard Drive Cable Replacement. If you can’t get the system into Target Mode, you have bigger problems.
