Logic Board Repair Cardiff, We Fix Apple Mac Logic Board

A logic board is considered the processing centre, or the brain if you like, of your Apple Mac. Your Apple Mac is composed of many different hardware parts and all of them obviously need to perform a function. The logic board takes you, the users, input and converts it in to your desired output by processing the commands in to electrical messages that your hardware components can understand. All the hardware parts in your Apple Mac are connected to the logic board. The logic board is the work horse of your Apple Mac and it processes an immense amount of data and because of this it could produce a lot of heat if not properly managed.

How do I know that they are issues with my logic board in my Apple Mac?

You may be having issues with your Apple Mac and you may not realise that your logic board is the cause of these problems because the problem only applies to one specific function of your Apple Mac. Whilst it could just be, for example, that the USB port of your Apple Mac is faulty, it is better to get a full diagnosis to ensure that the underlying problem isn’t actually your logic board.

Some of the most common signs that your logic board is damaged are:

  • The battery is not charging
  • The battery is not recognised
  • Not turning on
  • Randomly crashes or unexpectedly shuts down
  • Display or backlight issues
  • USB ports not working
  • Lots of fan activity, e.g. running at max speed or very noisy
  • Abnormal noises, e.g. clicking or grinding
  • MacBook overheating

How does NiwTech Cardiff diagnose a Apple Mac logic board failure?

If our Apple specialists at NiwTech suspect that the logic board is the problem then the first thing that we do is dismantle your Apple Mac and visually inspect the logic board. Sometimes there are tell-tale signs that the logic board is the problem, such as areas of corrosion or burn outs. Opening the Apple Mac and inspecting the hardware components is also a good way of assessing overall damage and ruling out other possible causes for your issues. Once we have isolated the fault, in this case the logic board we then test it with an ohmmeter to see exactly which components are faulty and causing the issue you are experiencing.

Our diagnosis is carried out in a minimum of 4 hours and a maximum of 24 hours. Once we have carried out our diagnosis we will explain to you the exact issue and you are in no way obligated to carry out the repair with us. If you do, and we hope you do, we can have your fully functioning device back to you in 24 working hours.

How does NiwTech repair a Apple Mac logic board failure?

Once we have completed our diagnosis our options are either to replace your logic board with an OEM part or to isolate and replace the faulty chips. There are thousands of chips within the logic board and if too many are damaged then it would be more feasible and efficient to replace the logic board. This task is incredibly labour intensive and our NiwTech experts are meticulous and work their hardest to always give you the best option to get your Apple Mac to you as quickly as possible, this means that we will have it back to you within 24 working hours.
