Therefore, if you have recently had a MacBook Air exhibit the 3 beep boot failure, strongly consider checking your thermal paste. Rebooted and NO 3 beeps! Once again, my MacBook Air appears to be working perfectly. I then removed the heatsink I found the thermal paste dried and hardened! I carefully removed all of the old paste and then applied new high quality thermal paste. Nothing else appeared burned, fractured, loose or disconnected.
When I got down to the logic board, I inspected the 8 visible 1 gigabit chips visible. Made no sense that DRAM of any sort would fail after 15 months. On a hunch, as I have noticed my MacBook Air has overheated in the past, I opened mine up to check the THERMAL PASTE. Services, 15 devices, 1 incoming serial ports Network Service: Wi-Fi,ĪirPort, en1 Serial ATA Device: WDC WD5000BPKT-75PK4T0, 500.NEWS FLASH for MacBook Air users with 3 Beeps at startup!!! I removed google drive from my computer as I had seen it caused problems with previous versions of OS X, and I reinstalled the OS.
I should also mention that my computer has been freezing and beeping three times. I'd really appreciate if someone could take a look at it.
