Capacitor discharge for replacing broken iMac power supply
Usually, if the iMac lost power suddenly (e.g. pulling the AC plug from power while it''s still switched on) you would need to allow some time for the capacitors to discharge before working on it. However, if the iMac was shut down properly (e.g. Apple > Shut Down) then it should discharge the power supply capacitor fairly quickly (not immediately, but close).

Why does my car lose power?
How do you restore engine power? Often, a new fuel or air filter will bring your performance back to normal. At other times, you may need to run a diagnostic test to find out why your engine light has suddenly illuminated at the same time as the power loss developed. The only way to restore prime performance is to fix the problem causing it.

6 Frequently Asked Questions about “The capacitor suddenly lost power and can t be restored”
Why is capacitor failure important?
Capacitor failure is a significant concern in electronics, as these components play a critical role in the functionality and longevity of electronic circuits. Understanding the nuances of capacitor failure is essential for diagnosing issues in electronic devices and implementing effective solutions.
Is it possible to reduce capacitor failures to zero?
However, it is difficult to reduce capacitor failures to zero with the current level of technology. Therefore, this report explains troubleshooting (diagnosis of failures and appropriate measures) to ensure proper and safe use of capacitors.
What happens if a capacitor is faulty?
When a capacitor is faulty, it fails to store and release electrical energy efficiently, leading to a decrease in overall electrical performance. One indicator of diminished electrical performance is when devices or equipment take longer than usual to turn on.
What happens if a power supply capacitor fails?
Power supply capacitors are often subjected to voltage surges and rapid switching, which can induce premature failure. The implications of capacitor failures in PCBs are far-reaching, ranging from minor signal degradation to complete system breakdown.
How do you know if a capacitor is not working properly?
Diminished electrical performance is a common sign that a capacitor is not working properly. This can manifest in various ways, such as reduced power output, flickering lights, or unexpected device shutdowns.
What happens if you don't replace an electrolytic capacitor?
The capacitor may be worn out, and continued use without replacement may result in an open failure or short circuit. Snap mount type aluminum electrolytic capacitors are used in power supply devices. The heat sink and the top of the capacitor were placed close together to reduce the thickness of the device.
