Most commonly affected are the charger and power plug, the controller, at least – a circuit and system error. The most rare and severe case – a cracked motherboard or hard drive.

How do you test:

  • after pressing the power button you can hear the melody of loading the operating system;
  • if there are indicators on/sleep, they burn appropriate light;
  • if you press Caps Lock, the related indicator comes on.

Problems with food

More often it happens that MacBook no longer included due to problems with nutrition.

If the computer does not turn on, here is a simple validation algorithm that needs to be run:

  • if your computer is connected to the outlet? the power outlet is working? it is easy to check.
  • connected to the power cord and adapter? normal forgetfulness and a loose connection can cause the lack of charge;
  • if everything is in order with power cord? if you have a spare analogue or charger it makes sense to try to charge mac with it;
  • connected, any accessories (printer, storage device, telephone)? unplug them and try again to press the power button;
  • after pressing the power button hold it for 10 seconds, then press it again.

No power

Often the problem is very simple and lies in the diet. The fault sockets, uninterruptible power supply, «pilot» happens most often.

The battery is out of order

If the computer is already a few years, it may not be included due to the fact that the battery is depleted. Usually there is an indicator that should light up while charging – when the charger is fully functional it makes sense to check it out.

By the way, breakage of the battery there are prerequisites too rapid discharge recently, data inconsistency of the battery indicator real time and so on. In this case, repair the Mac can only replace spent batteries.
