🍎 iMac Not Powering On? Here’s What to Do Before You Panic

You're all set to start your day—but your iMac won’t turn on. No chime, no screen, no sign of life. Don't worry—you're not alone. This issue is more common than you think, and in many cases, it's fixable without replacing your Mac.

At Gary’s Services, we specialize in diagnosing and repairing Apple devices, including iMacs that refuse to power on. Here’s what you should check first:

🔌 Basic Checks You Can Do at Home:

1. Check the Power Source

   • Make sure the wall socket is working (try another device).

   • Use a different power cable if available.

   • Plug directly into the wall—avoid extension leads or surge protectors for testing.

2. Inspect the Power Cord and Port

   • Look for fraying or signs of wear.

   • Ensure the power cord is firmly connected to the back of the iMac.

3. Reset the SMC (System Management Controller)

   • For Intel iMacs, unplug the power cable, wait 15 seconds, plug it back in, then wait 5 seconds before pressing the power button.

4. Listen and Look for Signs

   • Any fans spinning, LED lights flickering, or faint startup chimes?
     These are clues it’s getting some power, and the issue may be with the screen or GPU.

🛠️ Common Reasons for iMac Power Failure:

• Power supply unit (PSU) failure

• Faulty RAM or logic board

• Damaged graphics card

• Recent macOS update glitch or firmware issue

• Overheating or dust buildup inside the device
