macbook pro early 2011 13-inch service manual

Maybe place your 'sthetoscope' more inboard, to the left of the Return key and where its spindle motor lies, in order to distinguish? If it does turn out to be the speaker, the problem is software related something from the browser caused the OS to panic and freeze, leaving the speaker squawking. What about the right speaker/subwoofer? That's a tricky one to distinguish from the optical drive, since it is placed just above and flush to the optical drive slot. Whomever is the squeaker, if any of these, will need to be replaced under warranty. And the single fan on a 13'er is just to the left of the optical drive, meaning the edge of the case above the 7 or 8 keys. The optical drive, as expected, right under its slot. The HDD is located under the right palmrest. Move the stick about to determine the source of the noise. Take a capped pen or short stick to use as a makeshift sthetoscope: place one end against the bony area in front of your good ear while the other end against the Mac, this will enable you to hear all the sounds from within. We'll use an Old Mechanic's Trick to pinpoint the culprit. Time to determine the source of the squeak, whether it is mechanical or merely one of the speakers.įor the mechanical, note that there are three motors inside your Mac: the hard disk drive, the optical drive and the cooling fan. status shows up as Verified (geekspeak for 'hasn't given a hint of failure yet'). Again, report any error messages that appear.Įxcellent, that is good news. Then click Verify Disk again the test will take awhile and the Mac will be slow and unresponsive, as stated on the warning message that popped up and you clicked Verify Disk on. Will be called Macintosh HD unless you renamed it. Next, select the disk volume underneath the disk device.

Report back any error message that may appear. If it is Verified, click on the Verify Disk button and let it run.

If it says anything different from Verified, immediately make an appointment with your nearest Apple Store or Service Provider: the HDD needs to be replaced ASAP. What you want to look for is the S.M.A.R.T. On the bottom of the window you will see information about it. It is labeled XXX GB Apple HDD blablabla. On the left column of its window, select the HDD by clicking on it. And given it is an early 2011 model, this means the 1-year base warranty is soon coming to an end (if you are in an EU country, this may not apply).įirst off, start up Disk Utility, found in the Utilities folder. But since the system froze up, this may mean the hard disk drive is failing.

If it were only the chirping noise, I'd vote for a bad fan.
