SMC problem in A1342
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.
