Confirm that the power plug is plugged in

1. Sometimes, whether you’re in the midst of a severe storm or your power provider is performing continuous maintenance, the first instinct after a power outage is to unhook the power line to avoid a sudden surge when electricity is restored.
2. Before moving on to the next remedy, make sure your power cable is correctly plugged in and attempt to turn on your computer.
3. You might also try unplugging all of your devices (including your peripherals) and simply pressing and holding the power button for a while. This ought should discharge any leftover charge.

Unplug your computer and remove the battery

1. This functions as a kind of computer first aid. Simply unplug from all power sources, then take out the battery from your computer (or laptop).
2. Replace the battery after about five minutes, press and hold the power button for about 10 seconds while the device is still unplugged, and then plug it back in.
3. Failed to work Try the third option.

Check your source of power supply

1. If your computer is connected to a surge protector that also has a circuit breaker, it most likely tripped when the power went out and reset itself after that.
2. If your surge protector lacks a circuit breaker, the power surge has probably burned it out.
3. In this situation, either reset the circuit breaker or completely replace the surge protector since it cannot be used again. Simply reset your surge protector if the circuit breaker tripped.

6. If you’re having trouble correcting an error, your system may be partially damaged. We strongly advise Installing Restore, a program that will scan your computer and pinpoint the problem.

Check your computer’s fans

1. When you turn on the power supply and try to turn on the computer, if the fan doesn’t turn on, either the power supply needs to be replaced or the entire case has to be replaced.
2. If the case is present and the cooling fan doesn’t operate when the computer is turned on, the issue may be with the board’s power supply, in which case you may need to replace the motherboard, CPU, or both.
3. If your disks continue to operate even while your CPU is off, the surges that followed the power outage may have harmed the motherboard, CPU, or other crucial components of your computer. These components are prone to electrical harm.

When a power outage occurs, examine your hard disks

1. After a power loss, if your computer won’t turn on, you can take out the hard drives and put them in another computer.
2. But in terms of re-registering your operating system, you need a qualified individual to perform this.

After a power interruption, do a POST test.

1. After a power interruption, do a POST test.
2. Speakers are standard on computers. Try the POST test, which will play some beeps when the computer starts up, to see if your speakers are built-in.
3. Observing the pattern of these beeps can help you determine what is wrong with your machine. Once everything is in order, the typical startup sound resumes.

After a power outage, examine your CPU

1. After a power outage, examine your CPU.
2. While the power is on, you can check the vents on the side of your machine to accomplish this. On the motherboard, a green lamp is lit.
3. If this isn’t apparent, your Switch Mode Power Supply (SMPS) unit, which is located on the rear of the CPU, is probably the problem.
4. The SMPS fusing due to the power outage or abrupt spike of power (on/off) is one of the probable explanations. In this instance, swap it out.
5. If your computer’s green LED light is flashing, you must reset your PSU. Then, your computer should boot normally.
