You press the power button on your MacBook and… nothing. No Apple logo. No startup sound. Maybe the screen stays completely black, or perhaps your MacBook appears to have power but refuses to start.
Before assuming your MacBook is dead, don’t panic. A MacBook that won’t turn on can be caused by something as simple as a charger or a temporary software issue—or it could indicate a battery, display, liquid damage, or hardware problem.
Here are 10 things to try when your MacBook won’t turn on and how to know when it’s time to have it professionally diagnosed.
1. Make Sure Your MacBook Is Actually Getting Power
Start with the simplest possibility: your MacBook may simply have a dead battery. Connect your MacBook to its charger and give it a little time before trying to turn it on again. Also check:
- Is the charger firmly connected?
- Is the wall outlet working?
- Is the charging cable damaged?
- Is there debris inside the charging port?
- If you're using USB-C, have you tried another compatible charging port?
- Are you using a charger capable of providing enough power for your MacBook?
If possible, test with another compatible Apple or known-good charger. A completely discharged battery may not respond immediately after being plugged in.
2. Disconnect Everything From the MacBook
USB hubs, external drives, monitors, adapters and other accessories can occasionally interfere with startup. Disconnect everything except the power adapter. That includes:
- External hard drives
- USB flash drives
- USB hubs and docks
- External displays
- Printers
- Memory card readers
- Audio interfaces
- Other USB or Thunderbolt accessories
Once everything is disconnected, try starting your MacBook again. If it starts normally, reconnect your accessories one at a time. This can help identify whether a particular device or adapter is causing the problem.
3. Force the MacBook to Shut Down and Restart
Sometimes a MacBook isn't actually powered off—it may simply be frozen with a black screen. Press and hold the power button or Touch ID button for approximately 10 seconds. Release it, wait a few seconds, and then press the power button normally. If the Mac was stuck during sleep, startup or shutdown, this may be enough to bring it back.
4. Look Closely at the Screen
A MacBook that appears completely dead may actually be running with a display problem. Listen and look for signs of life. Does the MacBook:
- Make startup sounds?
- Produce fan noise?
- Feel warm?
- Show keyboard backlighting?
- Respond when you press Caps Lock?
- Work when connected to an external monitor?
If the computer appears to be running but the screen remains black, the problem may involve the display, backlight, display cable or another internal component rather than the Mac failing to power on.
5. Try Startup Options
If your MacBook powers on but won't boot normally, try accessing its startup options.
Apple Silicon Macs
On Macs with Apple silicon, such as M-series processors:
- Shut down the Mac.
- Press and continue holding the power button.
- Keep holding until startup options appear.
From there, you may be able to access recovery tools and other troubleshooting options.
Intel-Based Macs
Older Intel Macs use different startup key combinations depending on what you're trying to access.
If you're unsure which Mac you have or which startup procedure applies, avoid randomly changing settings. Professional diagnostics may be the safer option if important data is stored on the computer.
6. Think About What Happened Before It Stopped Working
This can be one of the most important clues. Did the MacBook stop turning on after:
- A macOS update?
- The battery completely died?
- A drop or impact?
- A liquid spill?
- Using a different charger?
- Overheating?
- Sitting unused for a long time?
- Suddenly shutting down?
The events immediately before the failure can help determine whether you're dealing with software, power, battery, display or logic board trouble. Be sure to tell your technician what happened before the Mac stopped working. That information can save valuable diagnostic time.
7. Check for Signs of Liquid Damage
Coffee, water, soda and other liquids can cause serious MacBook problems. Sometimes a MacBook continues working immediately after a spill and fails later as corrosion develops. If liquid was recently spilled on your MacBook, do not repeatedly attempt to power it on or charge it just to see if it still works.
Power and liquid are a bad combination for electronics. Disconnect the charger and have the Mac inspected as soon as possible. And despite the popular internet advice, don't put your MacBook in rice. Rice cannot remove liquid trapped inside the computer or repair corrosion on electronic components.
8. Consider the Battery
MacBook batteries don't last forever. As a battery ages, you may notice:
- Shorter battery life
- Unexpected shutdowns
- Difficulty charging
- Battery service warnings
- The Mac only working while connected to power
- Failure to start after the battery becomes completely discharged
A failed battery doesn't automatically mean you need a new MacBook. Depending on the model and condition of the computer, battery service may give it years of additional useful life.
Watch for Battery Swelling
A swollen battery requires special attention. Possible warning signs include:
- The trackpad becoming difficult to click
- The bottom case beginning to bulge
- The MacBook no longer sitting flat
- Gaps appearing in the enclosure
If you suspect battery swelling, stop using the MacBook and have it professionally inspected.
9. Don't Forget About Your Data
For many people, the MacBook itself isn't the most valuable thing inside it. It's the data. Photos. Business documents. School assignments. Financial records. Creative projects. Years of personal files. If your MacBook contains important information that isn't backed up, avoid repeatedly experimenting with aggressive troubleshooting methods that could put your data at additional risk.
Whenever possible, maintain a current backup using Time Machine or another reliable backup solution before problems occur.
10. Know When It's Time for Professional Diagnostics
If you've tried the basic troubleshooting steps and your MacBook still won't turn on, it's probably time to stop guessing. Possible causes can include:
- Failed battery
- Charging system problems
- USB-C or MagSafe issues
- Failed display
- Logic board problems
- Liquid damage
- Internal component failure
- macOS startup problems
Proper diagnostics can determine whether you're dealing with a relatively straightforward repair or something more serious.
Should You Repair or Replace a MacBook That Won't Turn On?
A MacBook that doesn't power on isn't automatically ready for recycling. Whether repair makes sense depends on several factors:
- Age of the MacBook
- Overall physical condition
- Type of failure
- Repair cost
- Current performance
- Whether your data is backed up
- Cost of replacing the computer
A professional diagnosis can help you make that decision based on the actual problem instead of guessing.

Frequently Asked Questions
Why is my MacBook not turning on even though it's plugged in?
Possible causes include a completely discharged or failed battery, damaged charger or cable, charging-port problem, display failure, software issue or internal hardware failure.
How do I force my MacBook to turn on?
Press and hold the power or Touch ID button for approximately 10 seconds. Release it, wait a few seconds, and press it again normally.
Why is my MacBook screen black but the computer is running?
A black screen can indicate a display, backlight or other hardware problem. If you hear sounds, see keyboard lighting or notice other signs that the Mac is running, the computer itself may be powered on.
Can a dead MacBook battery prevent it from turning on?
Yes. Battery and charging problems can prevent normal startup. Testing the Mac with the correct power adapter and professional diagnostics can help identify the cause.
Is a MacBook that won't turn on worth repairing?
Often, yes. The answer depends on the MacBook's age, condition and the component that failed. Getting an accurate diagnosis before replacing the computer can prevent you from spending money unnecessarily.
Can my files be recovered if my MacBook won't turn on?
Possibly, but data-recovery options vary considerably by Mac model and the type of failure. If the files are important and aren't backed up, tell your technician before repair work begins.
