What to do when a MacBook Pro is dropped and it won’t turn but Is beeping 3 times
I dropped my MacBook Pro and when I turn it on nothing appears on the screen it Judy’s beeps 3 times every 5 seconds .
It sounds like one or more memory DIMMs may have dislodged if your MacBook Pro has replaceable memory.
If it is a newer one that has soldered in memory, I'm afraid a connection has failed and it will need to be serviced.
Three successive tones, then a five-second pause (repeating): RAM doesn't pass a data integrity check. If you recently replaced or upgraded your computer's RAM, check to see if it was installed properly. If the issue continues, contact Apple Support.
