what to do if your computer is not turning on

what to do if your computer is not turning on

Hi guys this is Rosan from Widermart in this tutorial I'll be let you know how to troubleshoot a laptop or  a computer that won't turn on for one reason or the other.

Now I come across these situations quite a bit so I decided to start a blog on my troubleshooting processes and sharing with you guys.

Here on this site of course there are several possible reasons why your laptop might not turn on some major and some minor. 

So certainly some repairs are easier than others. What I'll be sharing with you in this topic, in this category are some repairing tips and approach to troubleshooting this kind of issues,

The situation of your laptop in case this one doesn't turn on, there are situations where you press your power button no lights come on, the hard drive is spinning, no sound from the cooling fan so basically nothing happens.

But there are other situations like the case of the laptop/computer where you press the power button and the LEDs come on, the fan and the hard drives seem to be spinning but nothing happens on the screen, no buck lights no texts.

So there is no single fix for all situations. I'll be troubleshooting each case based on the characteristics or symptoms of the problem and now without any discuss let's see what could be the issue in this situation.

Okay so for the case of max laptop what happens is where I press the power button it shows off the LED on the power button and some other LEDs go off but the LED on the power button still remains and then  on the screen there is no backlight and there is no text basically.

There is no sign of positive thing to show on the display so right now all we have is this LED on the power button and of course it's LEDs showed up before you know completely you listen carefully if you listen some sounds, the sounds of spinning hard drive.

But there is nothing is happening on the display, so usually if you have the kind of scenario it is absolutely no power or no life at all at the computer, then…

First check the power source

First you want to start checking is your power is your power source and usually the laptops. I mean even when there is nothing on like in this case the laptops have some kind of LED indicating the presence of power usually it good.

I mean sometimes it could be close to the power that support. But if you absolutely have no LED indicator around your computer then you might want to use a multimeter to test your power. 

Now for the case of this laptop is kind of an additional advantage as you can see it has an LED around this block here.

Check the adapter and pin

So it is definitely confirmed presence of power here so we don't have to worry about it but no charges, no power is in this LED. So if your adapter have any issue then you should use a multimeter to test. 

That is unethical and then you might want to check the pin and be sure that the pin is intact and also check that they connect on here.

It's not displaced in any way so for the case of this laptop or computer.

Check the BIOS

Next thing we want to check is that the BIOS has not been triggered of either buying power surge from the battery or the power that now normally when you press the power button. 

The first thing that comes on is values your BIOS coordinates with your assistant components to bring your computer your printing system.

Now in this case, on this screen whatsever usually you're going to see the logo like this is you're going to see their logo and some background text or what-have-you now that is your BIOS but you're not coordinating with your other system components to bring your computers right.

If BIOS doesn't even come on

Now in this case we haven't seen that so there are chances that the palace is a big to protect itself When you press the power button and nothing happens so your BIOS doesn't even come on.

In this case now we are going to try to fix that a simple way to do that is to first remove all the power sources from your computer. 

So we're going to remove it power adapter and then we are going to remove but now we're going to press and hold the power button for about 20 to 30 seconds and what I'm doing here basically is to discharge for residual power.

This correct footage from the capacitors, from these transistors and from any other components including the BIOS. 

So now we click after 30 seconds or so I'm going to return the power sources, so I'm going to also because I'm not sure how much power actually in the battery so I'm going to keep using the adapter.

Now I'm going to try to turn this on once again and see if it helps then okay, but  I still get some sounds from the cooling fan and from the hard drive so life in the laptop was still nothing on the screen. So this isn't the case of the virus okay.

Check the screen is dead or not

So now the next thing we're going to be checking here is the display, now obviously when you experience this kind of problem it's natural to think that your screen has gone bad but from experience that is not always the case.

However having tested these, the BIOS and also having confirmed that this is not the case of power.

Here the next thing we are going to be checking is the screen but this time around we're not going to be removing the screen or anything like that of course it's possible that a bug is in the LED or the part light. 

In the case many laptop might have gone bad or if there is in the LED time maybe later, but in this case we are going to be testing this by connecting our display through the serial port to an external display.

Now if you don't have any display you can use your television or someone else way but in this case I'm going to be here,  because this was a function according to the user so  it should show some text or some kind of initial screen.

And if in this display everything was fine, so this is not the case of display or something like that so the next thing we'll be checking is the run now usually some laptops will give some clue on this but not at all times.

Check the RAM and slots

Now this is what, this is a strong indicator I've been expecting this from where this is coming. this time it's either your monitor as a problem or your RAM has a problem. 

Those are the two common reasons where you are going to be any speed for the case of around.

If this absolutely completely there is no RAM in any of these slots then you are going to get indicating that there is no ram but that will come immediately when you power on the PC but not all laptops do that.

If you are not used to opening your computer but usually around is located in places that are easily accessible. Normally if you have different compartments in your laptop there will be some kind of indication of your RAM.

In the case of this laptop we just have one huge compartment so there are no indications if they are multiple compartments then you're going to create off and see which one has your. A minute now for this case I'm going to open up and try to locate the around.

Check the ROM

If I have two rum slots now I'm going to try to test I mean this could be the case of the ROM itself in but it could also be the case of this connector where you put, but then we're going to first start by testing out their arms.

So usually you will have two around slots, you might have one. okay so you replace and see if it works but for this case I'm going to try the two runs one after the other. 

Okay I'm going to leave the one inside and then try to power on and see if it works again.

The LEDs ratio disappear but the LED on the power button remains no sign. Now I'm not hearing the beep again maybe the view comes a bit later but anyways I'm going to go ahead and test the second and see now yes it has an operating system and now is booting up.

If the laptop has Windows 10 installed on it and now he's booting up, now I'm going to turn this off. 

Let's exhaust the possibilities because right now we can't be too sure if the problem is the RAM slot, so it has to be the ROM itself because we pulled out the other round from this slot.

It could also be that the two Rams do not call in it well but that would really be the case because good boat runs use 1.5 volt power. 

I'm still going to connect this other round to another port, I'll believe in Delta for this time and try again and see if it works then okay.

So again we have power on the led and this should I begin as usual but no life on the screen. 

So now we can come to a conclusion, in this case of course the computer can power and can run fairly fine I think, so ok guys that is it for today's troubleshooting. Hope you get some information how you fix this issue.

Windows failed to start or The PC is not booting from the correct Hard Drive

If here your turning on problem is solve then if here's a problem the computer was started and it's trying to load that was the BIOS and then in a few moments it will display an error message.

In this one the boot selection failed because a required device is inaccessible. Okay more exactly so many computer has one two and three and another one for hard drives there and it's not starting from the hard drive which has the operating systems.

It's starting from another one maybe there was an operating system on another hard drive sometime but now it's not there, so to fix the problem let's restart the computer.

You just press the enter is if you restarting if it does then press Delete to enter the BIOS, you can restart it with ctrl alt and delete also for the reset button. So you press Delete and you entered BIOS and let's go using the arrow keys.

Here you have to boot and the system says the first boot device is a hard drive serial ata free mega Western Digital on anything etc and the second one is a cd/dvd drive ok so the first boot device should be a hard drive.

That's fine the second one the cd/dvd and that's fine but you should choose which hard drive should be the first one. So to do that let's go here to hard disk drives and press enter and we have the hard drive and the operating system is on.

This one the harddrive ok and that should be here on the first position ok now if you use the keyboard - will bring a main menu item down.

You should  go to the harddrive and press the plus key the plus one the large one and harddrive went up is there press it once again harddisk is there in the first position.

Okay so you should boot the computer from the hard drive press escape to exit escape. Ok now even here it's showing the boot device is a serial ata hard drive and now you dare go to security and exit Save Changes and exit or just press f10 on the keyboard.

So Save Changes ok and now you can see the result the BIOS should load the operating system selection menu should appear and theoretically windows should start here's. 

The BIOS detecting things and now it should boot yes that should booting from the hard drive and shut down correctly so start Windows normally and now Windows is able to start. Ok so just make sure you're booting from the desired hard drive currently.

Conclusion

So I think you have gain some knowledge regarding the turn on issue and windows does not start problem. Thank you and we will meet in the next tutorial,  have a good day.
