hello. I have a macbook pro that when i turn it on it beeps 3 times then p. i know that this means no good banks, but what does that mean? is the RAM faulty?? It is second hand, but i got it from a trusted referbisher. I cant remember if he put new RAM in, but i know he put a new hard drive in. thanks.
MacBook Pro
3 Beeps means bad RAM.
Here's what you do, open the back of your macbook and take the RAM off.
Once the RAM is off, put it back in. Make sure you push it firmly.
Turn your Macbook back on.
If the beeps are stil present,
Go back to the back of your Macbook, take the RAM off in the first bank, the one you see.
Turn on your macbook again. If the beeps disappear, turn off your macbook and take the other RAM off and move that RAM to the top bank. Turn your macbook on again, if i doesn't beep, then you have a bad RAM.
If it beeps, then your upper slot is bad.
what does no good banks mean?
