Go through each step one by one and only advance if it still beeps.ġ) Power off and back on. Thats how I could search it out so fast^^ JKįor anyone getting 3 beeps at boot, there are a few things you can easily do. That being said my MBP is working very well after discovering and cleaning that little problem.hope this helps any of you out.Ĭheck to see if those little Asians forgot some important steps in the building process of the MBP. know what happens when electricity arcs across circuits? One discoloured (electrically burnt) piece of metal that didnt belong anywhere in my MBP. I used compressed air to remove these small electrical hazards from my MBP However I noticed when the MBP was open that there were small little pieces of metal shavings.(the kind found in a machinists shop) so back on the phone with apple support I went.Ī really nice guy on the other side of the phone instructed me to physically test the ram by taking them out and putting them back in one at a time.īoth ram sticks passed the test and hardware testing afterwards as well. I went to turn on my MBP and all it would do is beep at me. The next day after feeling so proud of myself for finally tracking down the problem. I also did a hardware test from the apps disk (os x disk 2) Thinking this might be the cause, I did what was asked of me. I contacted apple support right away and they taught me to reset the PRam. I was pretty confused about the whole beeping thing first thinkingĪnd then searching google I found alot of people were having beeping troubles.

Sometimes I turned on my MBP it didnt do this. I recently bought one of the brand new 2010 MBP '15 2.4 i5.ĭirectly out of the box it began to beep at me.
