MacBook Pro won’t turn on and charger flashing orange

Asked By 90 points N/A Posted on -

Just this day, I plugged my phone on my MacBook Pro through a USB so I can charge it. But an error appears and I don't really remember what it says. All I remember is that, it says something about too much charge of the device. So I unplugged my phone and plugged it back again. After doing that, my laptop turns off and it never turn on. When I connect the charger on it, it flashes with orange light but it still won't turn on. What happened and how can I fix it?

Possible causes:

  2. Resetting the System Management Controller (SMC) – see steps below
  3. Magsafe Adapter Fault – Test to see if the charger works on another device, or take it in to be tested
  4. Faulty Logic Board – this usually happens due to voltage fluctuation or power surge  you will need to take your device in for repairs

  1. Resetting the battery
  • Unplug all the devices, including the power, from your device.
  • Unscrew the bottom case –
