Is the top socket likely to suddenly become faulty? I have some WD-40 Fast Drying Contact cleaner but I didn't to start spraying that around without checking.Īm I best to just order a compatible 4gb single ram and run it in the bottom slot or take it to a local computer repair shop? It's second hand and 2 yrs old.Mac keeps restarting over and over? Mac keeps restarting on its own? MacBook Pro keeps restarting at boot? No worry. I am assuming from this the top socket has suddenly become faulty. I then tried to start up with RAM in only the top socket, it then beeped 3 times. I took out the top 2GB ram and it turned on, I then swapped the 2nd RAM with the 1st in the bottom socket and it started up again. I removed and reset the Ram but still 3 beeps. Yesterday when I went to turn it on it started beeping 3 times, so after scanning this board I realised it was an issue with the RAM. MacBook Pro 15', Early 2011, i7 2.0Ghz, 8GB RAM Here is a link to the pmset commands that I used. 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). I proceeded to re-seat the RAM and run a RAM diagnostics test ('rember' from Kelley Computing, ), the test passed. 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.
