Why my PC / MacBook won’t turn on?
PCs, iMac, and MacBook computers won’t turn on for a variety of reasons. One common cause is a faulty power supply unit (PSU). The PSU is responsible for providing power to the components in the computer, and if it fails, the computer will not be able to turn on. Other potential causes of a computer not turning on include a faulty motherboard, a dead or malfunctioning battery (in laptops), or loose or damaged cables. Additionally, a power surge or electrical storm can cause damage to the computer’s internal components and prevent it from powering on.
Another possible cause of a computer not turning on is overheating. If the computer’s cooling system is not functioning properly, the CPU and other components can become overheated, causing the computer to shut down or fail to power on. This can be caused by a malfunctioning fan or clogged air vents, which prevent proper airflow and cooling. Additionally, if the computer is exposed to excessive heat, such as being left in a hot car or near a heat source, this can cause damage to the internal components and prevent the computer from turning on. Ultimately, there are several potential causes of a computer not turning on, and it may require some troubleshooting to determine the exact cause and resolve the issue.


What to do when a PC / MacBook won’t turn on
If a PC / MacBook computer won’t turn on, there are several steps you can take to troubleshoot and resolve the issue. First, check to make sure that the power cable is securely plugged into both the computer and the power outlet. If the cable is loose or not connected properly, this could prevent the computer from receiving power. Additionally, try plugging the computer into a different power outlet to rule out any issues with the outlet itself.
If the power cable is connected properly and the computer still will not power on, for PCs or iMac, Mac Pro computers, the next step is to check the power supply unit (PSU). In some cases, a faulty PSU can prevent the computer from turning on. Try unplugging the PSU and plugging it back in to ensure that it is securely connected. If this does not resolve the issue, you may need to test the PSU or replace it entirely.
If your computer is a MacBook laptop that won’t turn on, try another charger and see if it works. Your MacBook should turn on normally with a working charger even when its battery is completely flat or has malfunctioned.
If the PSU or your MacBook charger is not the issue, it is possible that the problem lies with another component, such as the motherboard or CPU. In this case, it is necessary to take the computer to a professional technician for repair or replacement of the faulty component.
How much does it cost to fix a PC / MacBook that won’t turn on?
Costs for fixing a computer that does not turn on start from as low as $80 if the problem is something to do with its power supply or your MacBook charger, and can increase to $500+ if a complete PSU, or motherboard replacement is needed. When a computer is completely dead, it is not easy to know which part has failed, hence costs for repairs vary widely.
Note that this price is advisory only and should not be used as a fixed quote. It is best to leave it to our experienced technicians to test and confirm which components need to be fixed.


How long does it take to fix power issues on a computer?
Since it is not clear which part has failed and caused your computer not to turn on, the time it takes to fix will vary from same-day to 7 business days or more. We will do our best to complete the repairs on the same day when possible. However, parts may need to be ordered to fix power issues on your computer, which will take a few days to arrive.
