Won't boot, RAM beep
This is my first post here, been lurking for a while now and could not find an awnser to fix my problem.
I have an A1278 macbook that suddenly stopped turning on. It was working fine the last time I used, shut it down, and the next time I tried to turn on, it woudn’t boot, instead, it would beep in 5 to 5 seconds, with the light blinking together with it.
I look on an apple support page that this beep pattern was related to ram problems, so here is what I already tried:
1. Removed the sticks and tried to turn on with only one of them. Tried each stick in each slot.
2. Cleaned the slots and the contacts with isopropyl alcohol and tried the step 1 again
3. Unscrewed the ram slots and put it on again (I saw someone saying it would solve in other models and gave it a shot).
What else can I do? I didn’t switch any components at all, and right now I don’t have any working extra stick to test, but if needed I can search for one.
What other information would be useful to troubleshooting? This is my first time trying to solve anything on a macbook, all my experience in troubleshooting came from windows desktops and notebooks.
Thanks for your time and any help you can provide!
Ist dies eine gute Frage?
