There are times our Power Outlet may go bad, this will cause the computer not to turn on. To rule this out as the issue, all we have to do is unplug it and connected to another power outlet we know it’s working or plug something into that power outlet to see if any electricity it’s flowing through. This will confirm the outlet it’s working and putting out electricity needed to power on the computer system. Before you plug your computer back to it’s power source, Press and hold the power button for about 15-20 seconds then plug your computer system back to it’s power outlet.  Now try to turn the computer on. If the computer does not turn on, then move to step 2. However, if your computer does turn on, then the outlet you had it connected before it’s most likely defected.

There are time that are power cable and or chargers will fail for whatever reason. In this step we are going to find out if the power cable from our PC or Charger are the cause of the computer not powering on. This step usually will require you to have a spare Power cable and or charger. I’ve seen some PC Power cable in the 99 cents store if any in your area. cables are pretty cheap at local computer shop and might have them for about 5.00USD. Don’t have a spare one, If this a desktop, then most likely your computer screen will be using the same type of cable, Try to take  a look and if it does, swap it to test on your  desktop and or charger if it uses the same one .

For PC and Server as well some laptop using regular PC Power cable as show on the picture, you could perform the following step, with the spare cable try swamping it and see if it works ? If your computer system does powers on, then your problem it’s the Original power cord and will need to be replace . As for Laptops users , usually a charger will have detachable power cord, maybe different then a PC , this are pretty standard cable and most Cable Box, Cable Modems as well other electronic device may use the same power cord, Try swamping with those and see if it works on your charger, Make sure to look on the charger itself , there is a small led light that will light up when there is electricity going through it. If you do see a small light that should be turn on but it’s not, then your charger may be damage and will have to be replace. however if it does not have a light at all , then your next step will be to use a Volt Meter (For Technical People) to see if your charger it producing any power to your laptop and or tablet.  Volt reading should be around 15volts to 21 volts. If getting no volts reading at all from your charger, then your charger it’s damage. If your charger it’s working and or PC power cable it’s working, then move to step 3 to continue troubleshooting your computer power issue.

Follow this steps below to troubleshoot and see if it’s possible to get your computer system to power / turn back on to normal operation by the Power Supply (PSU) .  The steps below could be use on the following computer type.

On this section will be testing the Computer Power supply as well a few extra steps on the Laptop charger to see if it’s functioning correctly as it should be. Power supply on computer tends to breakdown, this could be do to  power supply over heating , not having enough power or blown out for whatever reason. Before we continue, we want to make sure the switch on the Power Supply it’s turn on ( See Picture ), Some some computers power supply have a switch in the back to turn off the computer when power button it’s not working . Make sure its turn on , if it was off, then hit the power button to see if your computer turns on, if it does not turn on, then continue reading. However if your computer turns on after switching the switch on but nothing display, then this is a different issue. May want to check our section on how to troubleshoot fix blank screen .

Laptops users, Some chargers have a LED Light on them to indicate it’s receiving power as I mention in my earlier step, if it does have a LED light and it’s on then continue reading, However, if it does have one but it’s not lit up, Then your charger may be defective and will need to be replace. If your charger  does not have a LED indicator on it but it’s working fine, Then plug into your laptop, As with any laptop, when you plug the power charger to it, a LED light should light up on the laptop itself. Picture below for reference .

If your laptops power LED lights up, but nothing happen when powering on, then your laptop power button most likely will have to be replace. Have a Technician take a look at it to confirm.

For Technical users. or if you are up for the challenge. This next step will require opening your computer case to expose the power supply cables which we are going to run a test on. Make sure to unplug the power cable from power supply.  As you could see on the picture , we are going to have to get our hand on the 20/24 pin cable which should be plug into the motherboard .

Once we have the cable in question in hand, will try to make a connection with 2 wires, if you look closely into the wires, you will see a few colors, there are 2 we are going to focus on for this test, A black one, which ever one it’s available and the green you see towards your right . We want to find a way to connect this 2 wires together. You could view a quick video about this procedure which should be displaying . Once we have those cable making contact , we are going to plug the power cable into the PSU and see if it turns on, If the power supply turns on, Then continue the next step. If it does not turn on, then you have a damage power which will need to be replace.

On this last final step on troubleshooting computer power on issue. For Technical users or the ones who are brave to try it :) We are going to perform one more test and this one will require opening the computer case once again and going back inside.

We are going to try to locate the motherboard power switch connection pin, now 90 percent of the computer out there have this switch, the others have a different kind of connection such as thin film ribbons which will required a technician to perform the test. If you look at the picture , you will see the pins and or wire will be looking for. The one will are looking for it’s label Power SW , Pwr SW or similar  , this connection it’s what connect your power button to your motherboard to turn it on. Now we are going to remove that Power SW cable from the motherboard exposing both pins that we need .

All we have to do now it’s find a way to make those 2 pins touch briefly to power on your PC . As you could see in the picture, there is a guy using a screwdriver to make a connection with both those pins. If doing this turns your computer on, Then your issue it’s with your power button and might want to replace it, if it does not turn on, then this means you have a bad motherboard :(
