My new MacBook was working properly until yesterday. Today it took a long time to get on and show something in the screen. Now it does not turn on (no sound or screen display) even when connected to the power line.
Tred was no event like fall or similar.
Any ideas of what may have caused it? How to proceed?
Take a lHave you already tried the steps suggested by Apple?
If your Mac won't turn on - Apple Support
Try Safe Boot:
- Shut down your Mac
- Wait until your computer turns off and after that press the Power button
- Right after you hear the startup tone, press and hold the Shift key
- Release the Shift key when you see a grey Apple sign and the progress bar below this sign
- After your Mac boots up, restart it as you usually do.
Apart from that, take a look at this Apple article and follow the instructions on Resetting NVRAM shown there: How to Reset NVRAM on your Mac - Apple Support
Try resetting the System Management Controller: https://support.apple.com/en-us/HT201295
Hope this helps!
