Today we will talk about MacBook Unibody Model A1342 malfunctions, and fixes.
If your computer beeps three times, there is a RAM problem. Either you have insufficient RAM to boot, or the RAM you have is faulty. First, access the RAM slot to make sure you have RAM installed. If you have two chips, reattach them first to try again Repair MacBook. If that doesn’t work, try one chip at a time to see if any chips prevent the machine from booting up. We offer replacement RAM to replace faulty chips. If none of the above methods work, you may have a bad logic board.
If your power adapter is faulty, the computer’s battery will drain. It will not charge. If your battery has a very low charge, it will be difficult to diagnose a bad power adapter. The easiest way to test this is to borrow a battery or power adapter to test on your machine. If you have the same problem with a charged battery, you will need a new logic board.
If there is no power to the machine the adapter is working, the next course of action is to replace the MagSafe board.
If the above steps do not solve your problem, replace the logic board.
Also, 9 beeps on startup show a logic board problem. Try contacting your nearest Apple representative to determine if they will fix the problem (be sure to back up your data first!) If not, you’ll have to replace the logic board yourself.
As soon as you unplug the computer from the power source, it shuts down
If your battery power adapter runs fine on the laptop only. Definitely gone bad. A dead battery can manifest itself in many forms: You should take it to a good repair MacBook unibody center before it turns into a serious problem. replacement can be purchased at our Repair MacBook Unibody.
The computer displays a flashing question mark when a bootable operating system is not found. The reason for this could be that your OS is corrupt, your computer isn’t equipped with enough RAM, or your hard drive is malfunctioning.
Try booting the OS CD. Run Apple’s Disk Utility to try to repair the disc. If this fails, reinstall your operating system. If you can, wipe the hard drive before reinstalling the OS.
