Chosen Solution
I recently dropped my Macbook Pro. It landed flat on the ground from a 2 to 3 foot drop. It appears to be fine but when I turn it on it beeps once, pauses, and then beeps once. It does this until I turn it off. I’ve tried reseating the RAM and checking the harddrive connection, neither seemed to fix the problem. Any other suggestions? Thanks
The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted). If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance. 1 beep = no RAM installed 2 beeps = incompatible RAM types 3 beeps = no good banks 4 beeps = no good boot images in the boot ROM (and/or bad sys config block) 5 beeps = processor is not usable In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once. Try one stick of RAM at a time in each slot.
Try taking out one stick, booting it, turning it off again, then putting the other stick in and booting it up again. It is a weird solution, but it worked for me. The same thing happened to me, but I took the ram out to inspect it and when I turned it back on…
