MacBook A1278 going to sleep while working.

My macbook is going to sleep while I’m working on it. This seems to be a normal issue, but I have tried all the solutions and nothing seems to work.

After contacting Apple Support, they determined it was a hardware issue.

Hopefully someone here knows what hardware to replace so I can do it myself and save some costs.

Tried:

  • Installing new SSD with Mojave (random sleeping continues during USB installation)
  • SMC reset
  • NVRam reset
  • TRIM Enabler installed
  • Caffeine installed
  • Battery removed and reinstalled
  • Sleep sensor removed and reinstalled

OK, you selected the wrong system this is a MacBook not a MacBook Pro!

So lets start this again from the top, I'll fix your system selection and show you the Hall sensors location. Your system is very different than this one.

@bmostrey - I've replaced my answer with the correct info. No! The part your pointing to does not have the sensor only the sleep LED.

Carefully review the new info.

Okay great! Before I buy this part, if I disconnect the sensor (step 14) would this fix my problem?

- de

Nope ;-}

Just like driving your car with only 3 wheels when you have a flat. Sometimes you just need to make the leap of faith.

Besides this is not an expensive part, nor a difficult part to put in.
