If your MacBook has no response when pressing the power button, you can try the following steps to troubleshoot: 1. Check the power and charging status to ensure that the charging cable is plugged in and the interface is not loose, try changing the charger or socket; 2. For M1 or updated chip model, check whether there is a "charging" prompt on the screen; 3. Force restart, press the power button for M1 and subsequent chip models for more than 10 seconds, and press the Command Control power button for Intel models; 4. Check whether it is a screen problem, connect to the external monitor to see if the screen can be displayed, and listen to whether there is sound on the fan or hard disk; 5. Reset the SMC and NVRAM, wait 30 seconds after shutting down the chip model, and then turn on the power supply button. Intel models hold down Shift Control Option and power button for 10 seconds before letting go, NVRAM Then press Option Command PR for about 20 seconds when powering on; if the above steps are invalid, it is recommended to go to the official Apple or trusted repair point for further inspection.
If your MacBook has no response when you press the power button, don't rush to send it to repair it. Although this situation seems scary, it is not that the hardware is completely broken, but that something goes wrong in a certain link. Let’s calmly check a few key points first, and you may be able to solve them yourself.

Check power and charging status
If the MacBook is not turned on, first check if it is out of power . Especially for those old models without battery indicators, you don’t know whether it has electricity or not.

- Make sure the charging cable is plugged in well and the interface is not loose
- Try changing a charger or socket to troubleshoot charging equipment
- If it is an M1 or a newer chip model, please check whether the screen is "charging" prompt when charging (it may be displayed even if it is not turned on).
Sometimes you think you are charged, but in fact you are just bad contact. You can try to unplug it a few times to confirm that the connection is stable.
Try to restart forcing
Sometimes the system is stuck and it looks like it doesn't turn on, but it's just a "fake death". At this time, you can use a forced restart method to wake it up:

- For Macs with M1 chip and later: Press and hold the power button for more than 10 seconds until the screen turns black and then the Apple logo reappears
- For Intel chip Mac: Press the Command Control power button at the same time
This operation will not delete your data, it is equivalent to a hard shutdown and restarting, which is suitable for dealing with system freezing.
There may be a problem with the screen, not the whole machine
Sometimes your MacBook has actually started, but the screen is not illuminated. How to judge?
- Connect the external monitor to see if the screen can be displayed
- When starting, listen to whether there is any fan rotation or the hard disk sound (the new model does not have a hard disk but there are other sounds).
- If there is a Touch Bar, see if it lights up
If the external monitor can display normally, it may be that the inner screen cable is loose or the backlight is broken. Just go to the repair point to disassemble the machine and check it, which may not be a big problem.
Last step: Reset SMC and NVRAM
The SMC (System Management Controller) is responsible for power management-related functions. If there is a problem with it, the MacBook may not be able to power on at all.
The reset methods of different models are slightly different:
- M1 and Mac with updated chip : shut down → wait 30 seconds → turn on
- Intel Mac with non-removable battery (most new models): Shut down → Press and hold Shift Control Option at the same time to power the three keys on the left for 10 seconds → Release → Turn on
NVRAM can also be cleared by the way (formerly known as PRAM):
- Press Option Command PR immediately when powering on, hold it for about 20 seconds before releasing
These operations can help restore the underlying system settings and sometimes solve seemingly serious boot problems.
Basically, these are the ways you can try at home. In most cases, through these steps of investigation, we can at least find out whether the problem lies in the power supply, system or hardware. If you have tried it all, it is still not possible, then it is recommended to bring the warranty information to Apple's official or trusted repair point for further inspection.
