Jun 12, 2020 I recently upgraded my ram in a 2009 MacBook pro and when I turned it back on I started getting the 3 beeps with nothing on screen. Carried out a troubleshoot of ram and slots below. I reinstalled old ram in both slots and got 3 beeps and nothing on screen. Then only installed new ram in bottom slot leaving top slot free - laptop turned on. A looping three beeps in between three seconds during startup is your iMac’s way of telling you that the operating system you’re trying to boot into is incompatible with your Mac hardware. The '3 beeps' means the memory is being detected as bad. The good news is that is one of the cheapest components to fix (assuming it actually is the memory at fault and not something else). So easy that I actually wouldn't take it into Apple. Much easier and cheaper to do it yourself. 15' Macbook Pro.
MacBook air 3 beeps indicate hardware problem most commonly faulty RAM. On MacBook pro A1278 or earlier MacBooks you can replace the ram if it got faulty. But on MacBook air and latest macbook pro ram is part of the logic board and soldered on the board. It is very important to diagnose which part or line is shorted on the line to pin point or address the problem. Unfortunately finding a short of the MacBook logic board and than reading the schematic digram is not something that anyone can do. We also offer MacBook logic board short course which you can join and learn find the MacBook logic board course info here.
On this MacBook air we find the short in one of the RAM. The capacitors on the Ram line were shorted to ground. To confirm this we perform direct voltage to the line and looked through thermal camera which confirmed the ram is shorted. see below picture.
Macbook Pro Beeps 3 Times And Won't Turn On
Some blogs suggest that it could be short under processor which can’t be right because if processor is shorted macboook won’t give three beeps. If ram is shorted you will see processor fan running continuously. In the above picture we can see clearly ram is over heating which confirms the ram is faulty. We removed the ram which was overheating at 70 degrees centigrade and tested the line of the short and tested the shorted line with multimeter and short was relieved. recalled the ram and solder it back on. Cleaned the board in ultrasonic machine. Before we put the MacBook logic board we recommend to put thermal pads on the ram see in below picture.

Thermal pads will release the any excessive heat off the ram and extend the life of hardware. To secure the thermal pads it is also recommended put caption tape on it.
