Battery not recognized and fans running really loud.
I have a macbook pro 13" Mid 2012 and I recently replaced the hard drive cable on it, upon startup I noticed that the battery indicator had an X on it and the laptop only works with the charger plugged in and the light on it is always green. My fans are also running pretty loud on start up and it takes a long time to load my profile, and when it does the computer in general is running slow. I already tried an SMC reset, I don't think the SMC reset is successful because the macbook starts up right away when it should not. After the reset you're supposed to press the power button for it to turn on. I've also noticed the LED on the front blinks 5 times before starting up. At one point when I did the SMC reset it did not turned on so I assumed it was successful which it was because the fans were not running on high anymore. But the battery problem still existed and now trying different methods of fixing the battery brought back the fan problem.
The battery indicator doesn't even blink green or light up so I tried unplugging the battery indicator from the logic board but the problem still persists.
I've also put in a friends battery into the laptop and same thing happens so I know it's not a battery problem. Is it most likely the logic board?
Is this a good question?
