MacBook is not turning on or has no power
If your MacBook is not turning on or has no power, there could be several reasons for this issue. Here are some troubleshooting steps you can try:
Check the power adapter: Make sure the power adapter is plugged into a working power outlet and the MagSafe connector is properly connected to your MacBook. If your charger is not working properly, your MacBook may not be able to charge or turn on. You can also try using a different power adapter to see if the issue is with the adapter itself.
Check the display: Sometimes the MacBook may appear to be not turning on, but it could be a display issue. Try shining a flashlight on the screen to see if you can see any images or the Apple logo. If you can, then the backlight or display may be the problem. If you can't see anything on the screen, try connecting your MacBook to an external display to see if it's the display that's not working.
Try booting in Safe Mode: If your MacBook is not turning on normally, try booting it in Safe Mode. To do this, hold down the Shift key while turning on your MacBook. If it boots up in Safe Mode, it could indicate an issue with the software or a third-party app preventing your MacBook from starting up normally.
Reset the SMC: The System Management Controller (SMC) controls many low-level functions on your MacBook, including power management. To reset the SMC, shut down your MacBook, then press and hold the Shift + Control + Option keys along with the power button for 10 seconds. Release the keys and then press the power button again to turn on your MacBook.
Check the battery: If your MacBook's battery is dead, it won't turn on. Try plugging in the charger and waiting for a few minutes to see if the battery charges up enough to turn on. If the battery is completely dead, it may take up to 30 minutes before it has enough charge to turn on. You can also try resetting it by following the instructions for resetting the SMC (above).
Test the RAM: Faulty RAM can cause a MacBook to not power on. Try removing and reseating the RAM or using different RAM sticks to see if this resolves the issue.
Check for hardware issues: A hardware problem with your MacBook may be preventing it from turning on. This could be caused by a faulty logic board, a damaged battery, or a malfunctioning power button.
Check for liquid damage: If your MacBook laptop is not turning on after liquid damage, it is important to act quickly to prevent further damage to the device. Here is how: How to deal with the water damage?
