If you suspect that there’s a problem with the logic board on one of your company’s MacBooks, use the Apple Hardware Test to conduct a set of evaluations to determine the problem. Newer MacBooks contain an Apple Hardware Test attribute which you get by pressing the”D” key when restarting, but to test an elderly MacBook, your computer needs to be on the Internet. If the Apple Hardware Test generates error codes, get the identification from AppleCare by giving them the codes.Using the Constructed Apple Hardware Test

1.Unplug all cables except for the power cable and then shut down the computer.

2.Restart the MacBook while holding down the “D” key.

3.Await the Apple Hardware Test to load, then click”Extended Test” in the right side of this Hardware Evaluation window.

4.Take note of any error codes that the Apple Hardware Test generates.

5. Call AppleCare and provide the support person the error codes, then program a repair session, if needed.Accessing the Apple Hardware Test Online
