something strange also is, i guess when the cable was loose?(hope that was the problem) i was not able to the apple hardware test at boot, it would start and just freeze and my computer would get very hot. It has been 3days now and have since updated to 10.8.5 and have not experienced any problems. So i blew air in the contacts plugged unplugged and plugged in again and wadded a little piece of paper onto the top off the plug to help keep it in place. so i checked my hard drive cables, hard drive side seemed fine but, the logic board side seemed loose,i say seemed loose because it came off with no effort or 'plug' feel.

Hi, Late MacBook Pro requires DDR3 1333MHz SO-DIMM 2GB, 4GB or 8GB pair. something strange i noticed though was i bumped my desk a little and it caused the screen to freeze and not boot only the 3beeps i thought that was strange since i have a apple SSD. 8:11 PM in response to Torcida California.

i taught maybe it was due to the 10.8.5 ML update so i restored from a time machine backup back to 10.8.4 seemed to work fine for a few days then same problem. tried changing ram (aftermarket and stock) seemed to be working fine then same problems with both ram. MacBook Pro 15', Early 2011, i7 2.Had a similar problem, three beeps, freezing, not able to boot, then all of a sudden working fine. As we’ve mentioned above, you may have recently replaced or upgraded the RAM. Here is a link to the pmset commands that I used. If your MacBook Air or Pro beeps 3 times in a row at five-second intervals, it is the signal that the RAM didn’t pass the data integrity check (in other words the RAM couldn’t load correctly). do not engage safe sleep unless the battery goes dead) using 'sudo pmset -a hibernatemode 3' the power is truly off) I turned the computer on and it started to resume from safe sleep and it was able to finish booting as it should, no beeping occurred and all was well.ġ) when resuming from safe sleep, computer would beep three times every five secondsĢ) I used 'sudo rm /private/var/vm/sleepimage' to delete the sleepimage fileģ) I used 'sudo pmset -a hibernatemode 1' to force safe sleep when I close the lid and/or choose sleep from the apple menuĤ) Booted from safe sleep and confirmed it was working as expected.ĥ) To go back to regular safe sleep mode (i.e. After putting it to sleep and making sure the LED in the front of the computer was NOT pulsing (i.e. By doing this I was able to force safe sleep to happen without waiting for the battery to be drained.

Where, setting hibernatemode to 1 tells your mac to always go into safe sleep. I learned a new terminal command to force the computer to always go into safe sleep. Now, I needed the Mac to go into 'safe sleep' which is challenging, because normally this would only happen if the battery was completely depleated. I decided to delete the file so that it would get re-created the next time the Mac was put to sleep. I had read that any time you put your mac to sleep the sleepimage file will get created, if it doesn't exist already. Because of the unique situation where the computer would start to resume just fine and then get the 3 tones, it seemed related to the safe sleep file (/private/var/vm/sleepimage).

I decided that instead of calling Apple back, I would try fixing this myself since it appeared to be a software issue not a hardware issue. The technician booted up the laptop using the special Apple network diagnostics and all of the hardware 'checked out' as just fine. I called Apple to schedule a visit with my local Apple authorized technician, in Redding, CA). 3 million 1999-2002 Chevrolet Silverado and GMC Sierra pickups, the complaints continue rolling in. I proceeded to re-seat the RAM and run a RAM diagnostics test ('rember' from Kelley Computing, ), the test passed. The new beep codes emit only memory failure symptoms. During that time the front LED would flash at the same pattern.īecause I had replaced the RAM (came with 4, wanted 8, but didn't want to pay the Apple price, so instead I bought from - they are amazing) I had suspected that maybe the RAM was bad or that it wasn't seated properly. the battery went completely dead while the computer was asleep, causing it to resume from the sleep image file when power was plugged in) when I would bring it out of safe sleep it would make it 50% through the resume process and then I would get 3 tones/beeps separated by about 5 seconds and then repeating the same sequence.

I ran into an issue with my wife's MacBook Pro (Early 2011, 2.0 i7) where anytime it would go into safe sleep (i.e.
