Fixing Laptops Black Blank Display Problem

Everybody hates to look at a black blank display on their systems startup. And I know it’s kind of hard to take, to find your laptop just broke down in the middle your happy life.

You push the power button, the power light starts to show up, the fan is running, the drive is moving, and bamm!! there is still nothing comes up on the screen and the display remains blank.

In hardware language, we mainly called this issue a No Display Problem;

And in this problem, your laptop’s motherboard is supplying the proper power supply to all the attached hardware, but the BIOS still isn’t able to Boot UP your computer because of some minor or maybe major internal hardware failure of your laptop.

Or it’s also possible that your motherboard is booting up properly, but the laptop’s display isn’t able to show anything on it.

So as now you know anything can happen to any laptop, and the best way to find things out. You’ll do have to follow the step by step inspection guide given below in order to start your laptop and fix the problem completely.

In case if your laptop doesn’t show you any sign of power supply, then it means that you have a different problem with your laptop and now the only thing what you can do is to use some different (but same) Power Adaptor on your laptop just for the testing purpose. Or otherwise, you can take it to the repair shop because in this ‘Dead Condition Laptop’ its 100% chance that there is definitely some hardware got faulty and stops the whole motherboard’s power supply circulation.

So, Lets See How to Fix A Blank Screen Laptop Problem;

To troubleshoot the problem on a users end, you only have four different methods what you can try on any laptop before sending it to the repair shop. And Im only saying because there are only 60% of chance that you will fix your laptop on your own.

It’s all happen because when a normal user doesn’t have any testing components or devices, to Check/Cross-check with the faulty hardware.

So, don’t be sad about that and just give it a try;

#1 Display Checkup

In case when you turn ON your laptop and starts to hearing all the startup sounds, then it quite possible that the problem is occurring just because of a faulty display screen of your laptop. Sometimes it’s also possible that the display cable of your laptop which was mainly attached to the motherboard got loose and creating the problem.

Anything can happen to your laptop, and the best way to find things out is to test your laptop’s display output on some other external monitor. Thats how you can easily troubleshoot your laptop and find it that really the internal fault or it just a display.

If in case you can see the display output on the external screen is working perfect and you can able to use your computer, then it means that you have a problem with your display screen and it can be loose or faulty and to fix it, you’ll have to de-assemble your laptop to find the actual problem.

Here I have some tutorials to show you how to do that;

#2 BIOS Checkup

BIOS is the one who actually boots up your computer from the starting, and if something happens to the BIOS then it definite to have this kind of problem with your laptop.

The best way to trigger the faulty is to reset it and these given steps will help you to reset your laptops bios manually:

Step 1 – First, you’ll need to fully turn OFF your laptop and then unplug the power adaptor & then the battery too.

Step 2 – Now press the laptop’s power button for about 20 seconds to reset the CMOS configuration.

Step 4 – After that, Turn ON your laptop without even using the battery and by just attaching the power cable only.

Most of the times this will completely reset your bios and now you are able to run your laptop, just like as it was before. In case, if you still seeing the blank screen then it’s possible that the above-given procedure doesn’t work on your laptop’s model and then now you’ll need to de-assemble your laptop, in order to properly reset the BIOS by removing the CMOS Battery for about 5 seconds.

#3 RAM Checkup

Commonly, 90% of you people will fix your problem by following this step. Im only saying because RAM is the one who easily get dirty due to age or bad moistures surrounding. And not just that, it’s also possible that your RAM got dead too.

Let’s See How to Fix A RAM Problem:

Step 1 – Unplug all the power source like a battery or power adaptor.

Step 2 – Now open your laptop’s back panel case, where actually the ram is located and then remove the RAM from its RAM Slot.

Step 3 – After that, you’ll need to clean your laptops RAM properly.

Step 4 – Now it’s time to put the RAM back in its place. In case, if you have two RAM Stick installed in your computer then you can try to remove one of them and then Turn ON your Laptop. If your PC still wont work, then just remove the RAM from its slot and then install another one on that same RAM Slot. If your computer still wont able to work out, then just repeat the previous steps on the other RAM slot of your Laptop.

And that’s how you can easily find which one of your RAM or RAM’s Slot isn’t working properly. You can also borrow a compatible ‘RAM Stick’ from one of your friend in case if you don’t have any working RAM stick for testing (other than your systems RAM).

If you find your RAM faulty, then believe it or not but cleaning it can increase the chance 80% that it will work again in your computer. Heres is the link: RAM Cleaning One Solution To Fix Memory Related Problems, and for other 20% heres the second link which can help too; How to Repair a Dead RAM Stick (Random Access Memory)?

#4 Everything Else What You Can Do

Sorry to say, but let’s come to the bad part about this tutorial because now you really are run out all of your luck. The reason I told you so because now, its definite to have a major hardware related problem in your laptop and its also possible that you wont be able to fix it now.

But still, I have something that you can try;

  • Now, the first thing what you can do is to disable your whole laptop and try to start your motherboard by using only the RAM and Processor. To do that, you can watch a de-assembly video of your laptop on YouTube and put the motherboard out of its case. And that will help you to know if any eliminated hardware is faulty or not.
  • If you have same or a compatible Process for your laptop’s motherboard (other than the one which your laptop is using), then you can also try to use it to confirm it’s a processor fault or not.
  • If processor isn’t the one who’s creating the problem, then the next thing what you’ll need to check is BIOS. Yes, resting BIOS isnt the only thing which can fix it. You have to Flash the whole BIOS Chip by using the BIOS Flashing Machine if the internal program got faulty.
  • Having a faulty GPU (Graphics Processing Unit; Graphics Chip) is the last thing what you can expect from a No Display stuffing motherboard. You can take some help from some professionals to confirm about it because I can’t test your motherboard through the internet. So, Good Luck! 🙂

  1. Thanks, I first tried #2 (Bios Checkup), it looked like I was going to get a result but then the screen went black again. Then I tried #3 (RAM Checkup), and boom! that was my answer.
    I cleaned my two Rams as instructed and put them back. I decided to run a check up while the system was boothing, at a point the pictures started cracking and went black again. This time I decided to remove one of my RAMS and that was it, the screen displayed fine.
    I discovered one of my RAMS was bad so I’d have to change it. PROBLEM SOLVED 👍
    Thanks again.

  2. Sometimes its motherboards fault. How to explain it… part on motherboard get stupid cuz they had some minor electric failure and all you need to do is plug battery out of your laptop press the on button for 30 seconds and then return battery and try to start your laptop.

  3. My lapi has stopped working and I think it’s a same problem as discussed above.But I am getting a sound for some time while starting, does anyone know what exactly is wrong ??

  4. Hi,
    I have a U310. I power on and get a black screen, I connect to my tv and it looks fine. Sometimes when I restarted the monitor works fine and looks fine but if I restart it again I get the black screen but I connect to the tv and it’s working fine. Any idea why it’s doing this?
    Thanks for your advice

  5. hello
    my laptop dell latitude has got a problem with its display , i took out ram and place it back after cleaning but nothing happened!
    when this problem started my laptop used to start after 4 or 5 tries … then after 9 or 10 and now it does not give any display? repair guy said its problem with its chipset
    Tell me if i could solve problem myself?

  6. Hi could bios upgrade cause the no display issue because I observed that after month of upgrading my system bios, I start experiencing the no display issue…and am not sure it’s the display issue cos I have changed the display I.C but I keep experiencing the same issue. And am also not sure that the ram is the problem because the system displays after 14-15 hours of no display. So please can the BIOS upgrade cause the no display issue and if it is what’s the way out. Please I need an answer soon. Thanks

    • I can’t say anything without troubleshooting the system.
      Maybe you should need to hire some local computer engineer and I think, he will figure it out.

  7. I tried everything as you said but no work was done. Please tell me approximately how much cost to pay change the GPU chip. I think my laptop GPU chips have gone bad.

  8. Thanks a lot Madhur. My laptop is up and running again after following the ram cleaning steps that you recommended. Keep up the good work!!

  9. Hi, my laptop sometimes give me blank screen upon start up
    I went to repair it , the guy said it was the IC or the joint is dirty, not the LCD
    He replaced the IC, however I still got the same problem…
    He then told me to “smack” my laptop from below & restart….it did work but I feel that he is trying to destroy all components by doing this solution,
    Did I get cheated??
    He did said he will take responsibility but only by cleaning the “joint”, is he referring to the ram?

  10. Hi Madhur

  12. I have a new hp laptop that I was never able to use. I take it out of the box, plug it in to start charging it and do the first time initial setup of the laptop. I leave it plugged in overnight to get a full charge. Next time I go to use it it powers on but is only a blank screen. Could something have happened to cause this from a possible power outage? I tried the steps taking out the battery and still nothing.


  14. bro I have the same problem with my laptop.. but the one difference is that it displays the screen sometimes and sometimes it doesn’t… what do I have to do now because its not the issue of RAM as far as I know.. plus I have done this bios checkup too..

  15. Hello, please help me with my laptop. It bumped on the wall but not so hard a slight when i was carrying it ito my room. The screen part was bumped. And it turns to black screen. The screen has light (dark gray that u can see while opening windows). What do u think its problem? Its still working but i can’t see anything.

  16. Hello from Greece
    My dear friend Madhur Tj
    You saved my life. And i am not talking about money or job, i am talking about my personality and how i feel.
    Before 2 weeks, my cοusιn gave to me her laptop. She told me that the problem was that in random time, stop, hang. The laptop was for one year out of work. The last thing she did , was to gave it to a specialist to fix it. He told her that the problem was thε Hard Drive, and he wanτed 150 euros to replace it.
    First time i turn on it, i understood that it was not the HD, because the drive run normally and i understood it from its sound. It was ok. The first think i notice that it was strange, was that the air fun was working in very high speed and for ever. I mean, from the start to the shut down. Οfcourse the BIOS battery was out of wοrk, and the first thing i did was to disassemble the laptop and replace the BIOS battery. Then i understood why the fun was working in this speed and for ever. Somebody (there was a paper inside indicate that there was a previous service before 3 years) cut the power cable of the fun (the red) and link it to the USB on the motherboard. As a result the fun did not communicate with the CPU temperature sensor on the motherboard to take the proper current, and because of this, it receives all the time 11 volt from the USB. There was a moment, when i by mistake touch on metal on the laptop (one of 3 USB) and voltage hit me ! He left a very small piece (4mm) of cable, and it was very difficult for me to join the cable to its proper place, because i do not have the proper equipment. Any way i did it, then I assemble the laptop. After this, there was many problems with BIOS corruptions because, laptop suddenly shows green lines on display and then stooped. And when i reboot, the HD was working but i have no image on display, just a black screen. So many, many times i shut it down not the right way, and the BIOS was corrupt. It was a very big pain to find how to recover the BIOS. And you know that if the BIOS do not work, you can do nothing. No bootable CD, no bootable USB, nothing. Finally i manage to recover BIOS. Windows start to loading , but only to the state where i could see the mouse (aalso move it) nothing more. I though i must make a clean reinstall of Windows, and i did it. After this clean installation, Windows start normally, and works for one day. I thought that i repaired it, but the next day, nothing but a black display. I heard the welcome in windows sound, but i did not realize at this point that Windows launch normally, with a black screen. I have check the display with other monitors and i know that the display was ok.
    For 7 days nigh and day working on the laptop. I was sleeping only for 3-4 hours a day , I was gone crazy. I know that i could fix it, but i did not know what exactly was the problem. I was sure that the HD was ok. From the green lines on the display i understood that there was a problem with the graphics, but i though it was a drivers issue. Also i noticed that in the motherbord there was 2 micro-proccessors that was cracked, but i did not know what exactly was these micro prossesors, and i thought one of them was the graphic chip. But i did not have the equipment to replace it.(finally i see that these two microprocessors were not the GPU. The only think i did it was to cover the crack with a silicon, not humidity enter) So the only option i had it was to replace the motherboard. I did not find a new one, but a used, for about 50 euros.
    Fortunately i read, (after i had read thousands of sites, videos,blogs, forums, after i disassemble and assemble over 15 times the laptop), your site and it was described exactly the same problem. Windows starts but not display. I completly did not know about the air flowing method. I could not imagine that there was such a method. I was 100% sure that this was the problem and i will managed to fix the laptop.
    It was 7 pm (stores closed at 8.30) I call to my girlfriend if see can give me her hair hot air gun, because i did not know the differences in heat between hot air gun and hot air gun for hair. Fortunately in the middle of the route to my girlfriend, there is a store. I stopped there , look for a hot air gun, and buy one.
    I follow a procedure little different from yours because i wanted to have live watch, so i watched a video, where there were a few differences in the times (40 seconds preheat from far , 30 seconds heat from close, and also heat from far on the opposite side)
    You cannot image how i felt when i push the on button of the laptop, and the display started.
    Thank you very very much !
    I wish every good to you life !

  17. i read the re-balling method in the above link (thanks for the link), and i think i will try it, next time.
    But before i will try, i have two questions, if you please.
    1) Can i remove the Graphic card, from the motherboard, by just heating it with my hot air gun (do you know the time ?), or must i have a special tool ? And if there is a special tool, what is the difference (i want to understand why one method is OK and the other, is not the proper, in order to (may be) found a solution of my own (you never know…)
    2) i read in a couple of sites that the re-balling method, do not repair the card. As they say, the problem with these cards is not the balls under the bottom surface of the card, but the balls inside the card, and with the material that “hold” these balls (that are smaller than the outside balls) inside the card. And this is the case in certain brand graphic cards of a certain years. So the reason that re-balling (as well as re-flowing) fix the card, is the heat and not the balls replacement. The heat, force the, inside the card, material that holds the inner, small balls, to come to the right (initial) formation and shape, and this, also, make the inner balls comes to the right (initial) formation and shape, having as result, fixing the card, but not permanently. Because this inner material that holds the inner balls, is defective, the “deformation” will happen again.

    Because i believe that you are good and serious in what you are doing, i am interested in your opinion.
    And finally, if the above mentioned sites (against re-balling) have right, what can we do ? Can we replace the card, of course with no the same brand (because we assumed that they are defective) ? With what card can we replace it ? Is it easy to find the drivers and will it work to our system ?

    • First of all, don’t try to do all the things by your self. Not every laptop works without a graphics chip. Let the hot gun only remains to the reflow, you can’t think about to reballing with it. Everything needs a proper and professional machinery to fix it. Or otherwise, you’ll definitely make your board dead.

      Second, reballing is good. You can’t doubt about that, even the repair shop will give you at least 3 months warranty of its work. In case, if your GPU chip is faulty, then nobody in the world can fix it and you’ll do need to replace the chip.

      And no, you can’t use any other GPU chip (only some laptop model supports).

  18. Hi MJ,
    Thanks for ur wonderful tips. My Acer laptop of 4 years had a flickering screen and I could not log on nor access files on it two weeks ago. After following ur tips today, I pulled out the battery and checked the Ram but did not have the necessary cleaning tools/items to do a thorough cleaning. I installed the ram and tried switching on the laptop and now it has gone totally blank. Grateful for ur expertise advice on how I can fix the problem. Thanks
