If you’re having trouble getting your iMac to turn on and it won’t turn on, don’t panic. There are a few simple steps you can try to troubleshoot the issue and get your iMac up and running again.
Check the Power Cord and Outlet
First, make sure that the power cord is securely plugged into the back of the iMac and into a working outlet. If the iMac still won’t turn on, try unplugging the power cord and plugging it back in after a few minutes. This can sometimes reset the iMac’s power supply and get it to turn on.ADVERTISEMENTS
Unplug Other Cables and Devices
Next, try unplugging any other cables or devices that are connected to the iMac, such as external hard drives or monitors. This can sometimes resolve issues with the iMac’s power supply.
Reset the SMC
If the iMac still won’t turn on, you may need to try resetting the SMC (System Management Controller). To do this, shut down the iMac and unplug the power cord. Wait at least 15 seconds, then press and hold the power button for about 5 seconds. Plug the power cord back in and turn the iMac on.
Contact Apple Support for Assistance
If none of these steps work, you may need to contact Apple Support for further assistance. They will be able to provide you with more detailed troubleshooting steps and, if necessary, help you schedule a repair.
Don’t Worry, Most iMacs are Reliable
In the meantime, try not to worry too much. Most iMacs are built to be durable and reliable, and with a little troubleshooting, you should be able to get your iMac up and running again in no time.
