如果MacBook無(wú)法開機(jī)，先檢查電源是否插好、插座是否正常工作，有時(shí)只是電源或電池問(wèn)題。 1.嘗試更換插座或直接連接電源，檢查充電線和接口是否有損壞；2.長(zhǎng)按電源鍵10秒強(qiáng)制重啟，M1芯片機(jī)型同樣適用；3.重置SMC（Intel機(jī)型需同時(shí)按Shift Control Option 電源鍵10秒）；4.觀察是否有風(fēng)扇聲、啟動(dòng)音、鍵盤燈等跡象，並嘗試外接顯示器；5.若仍無(wú)反應(yīng)，排查電池膨脹、保修狀態(tài)，考慮聯(lián)繫Apple官方維修點(diǎn)或嘗試進(jìn)入恢復(fù)模式。多數(shù)情況是小故障，先從基礎(chǔ)排查再?zèng)Q定是否送修。

If your MacBook won't turn on, don't panic right away — it might not be dead. Start by checking the obvious: is the charger plugged in properly? Is the outlet working? Sometimes it's just a power issue or a drained battery.

Once you've ruled out the basics, there are a few steps you can take to try and bring it back to life.

Check the Power Source and Connections

This may sound basic, but it's surprising how often a loose connection or faulty outlet is the real problem.

• Try a different wall outlet to make sure it's not the socket.
• If you're using a power strip or surge protector, bypass it temporarily.
• Inspect the charging cable and MagSafe or USB-C connector for damage.
• If possible, try a different charger (especially if you have access to another MacBook charger of the same type).

Also, look for any LED indicators on the charger. A green light usually means it's charging; amber means it's charging slowly or there's an issue.

Force Restart or Reset the System Management Controller (SMC)

Sometimes the system gets stuck and doesn't respond like it should.

Try this:

• Hold the power button for at least 10 seconds, then release it. Wait a few seconds and press it again to turn the MacBook on.
• On MacBooks with Apple Silicon (M1 chip or later), holding the power button is how you shut them down or force restart, so this is still relevant.
• If that doesn't work, resetting the SMC can help — especially if the issue involves power delivery or battery management.

For Intel-based MacBooks:

1. Shut it down.
2. Unplug the power adapter.
3. Press and hold Shift Control Option on the left side of the keyboard and the power button at the same time for 10 seconds.
4. Release everything, plug the adapter back in, and try turning it on.

On Apple Silicon Macs, the SMC is managed differently, so the reset happens automatically when you leave it unplugged for a while after shutting it down.

Look for Signs of Life

Even if the screen stays black, pay attention to other signs that the machine might be on.

• Do you hear fan noise or a startup chime?
• Does the trackpad or keyboard light up briefly?
• Can you feel any warmth from the bottom?

These could mean the machine is running but the display isn't working. In that case, try connecting an external monitor. If the MacBook wakes up and shows the desktop on the second screen, the internal display or its connection might be the problem.

Also, if you're hearing repeated beeps or tones when trying to start up, those can indicate hardware issues — especially memory problems.

What If It Still Doesn't Work?

At this point, if nothing seems to work, the issue could be more serious — like a failed logic board, a bad battery, or corrupted firmware.

Before jumping to conclusions:

• Make sure the battery isn't swollen. If it looks bloated, stop using it immediately and contact Apple.
• If your MacBook is under warranty or AppleCare, get it checked at an Apple Store or authorized service provider.
• If it's older and out of warranty, consider repair costs vs replacement.

If you're comfortable with tech support, you can also try booting into recovery mode (by holding Command R during startup) to see if the system responds. But if the machine won't even power up, that's likely a hardware issue.

基本上就這些。很多情況其實(shí)只是小問(wèn)題，比如電源沒(méi)插好或者係統(tǒng)卡住了。先從簡(jiǎn)單的開始排查，別急著送修。如果實(shí)在搞不定，再找專業(yè)人士也不遲。
