    Did you have a chance to test the laptop with an external monitor attached to the VGA port? Can you get video on the external monitor?

    First of all, I would check memory modules. It’s possible that one of the modules failed.
    1. Try reconnecting memory modules. Remove them from the motherboard and install back in.
    2. Test your laptop with each module installed separately. If one of them is faulty, the laptop will start when the bad module is removed.

    shripati,

    now the problem is that i get discolorations on the screen with various line color patterns..till recently i had this problem..but then i tried reinstaling windows 7..the installation didnt happen successfully and now i have a laptop with no display…bt it powers up as i see bright screen when plugged in..

    Most likely this is a known VGA chip failure. This is a common problem with HP Pavilion dv2000/dv6000/dv9000 series laptops. HP knows about this failure and there is a chance you can get a free repair from HP, if your laptop qualifies.
    Call HP and find out if your laptop qualifies for a free repair. If not, you’ll have to replace the motherboard or try fixing the motherboard.

    Recently I had a similar laptop Compaq Presario v6000 with the video chip failure. I baked the motherboard in the oven and it fixed the problem, at least for now.

  5. Hi,

    I have a Toshiba M400 laptop with Ubuntu 10.4 installed. I had a problem about “blinking” and “fan runs at full speed”, but last week this situation had been occurring sometimes. However, now I couldn’t manage to boot.

    I suppose that the existence of this problem is due to the broken anti shock sensor. So in order to solve (or probably solve booting problem), I need to know how to disable shock sensor from motherboard.

    Thanks for your help.

    Forget about it. If you have a failed motherboard, you’ll have to replace it with a new one.

    No boot and fan runs full speed? Sounds like motherboard failure. I’ve seen it happening before with Toshiba laptops.
    Just in case, try removing RAM modules one by one. Test the laptop with each module separately. If it doesn’t help, probably it’s bad motherboard.

    gerard,

    PLZZ HELP ME MY LOP TOP IS DNT WORKING when i open it the lop top dont seem to open its still blank and the cooling fan is not moving at all plzz help me plzz wat should i do?

    It’s hard to tell what is going on without testing the laptop.
    Does the laptop have any LED lights when the AC adapter plugged?
    First of all try reseating memory modules. If you have two memory modules, try removing them one by one. It could be memory failure.

  11. Laptop screen remains blank no boot sound or anything. The Laptop fan starts, the power button light comes on, the cd tray opens. Nothing else works. What could be the possible problems, where can I look? Compaq Presario

    This could be memory related failure. Try removing memory modules one at a time. Test your laptop with each memory module individually. One of the modules could be bad.

    hi, i bought a dell laptop a year back and im facing this random screen blackout problem since 6 months…its a recurring problem as it happens for 4-5 days and then automatically pauses for some days i contacted dell they sent me driver but it didnt work and then they told me to reinstall my OS…but THAT DIDNT HELP EITHER :(
    lately it just happened that while this problem occured my lappy wont start and when i pressed the power button “startup repair” would start and then it wud say windows is unable to repair so click finish to shut down!
    i contacted repair centre and he formatted my lappy for rs.500 and told that the problem was probably due to dust and he has settld it so it wont occur again…BUT it occured gain the same day…this time i noticed that while it occered the laptop was hot after working 1.5hrs and its fan waas not working…in short im pissed and WANT THIS PROBLEM TO GO!!

    My problem:

    My Toshiba M400 (PPM40C-1200TE) recently started to perform poorly, lagging, getting stuck, and occasionally randomly restarting. Other times, the screen would just black out, fan would blast, and the power light would blink orange regularly.
    Although I didn’t realize it at first, the restarts/blackouts would happen whenever I moved the laptop. Hmm, that’s familiar cz whenever I moved the laptop before, the laptop would have for about 1 sec, but continue smoothly where it left off. This is due to Toshiba’s HDD Protection (basically, the HD r/w head locks up whenever the laptop moves to prevent HD damage).

    I’m guessing that recently, the sensor / accelerometer went bad and became oversensitive. This could explain the general lagginess (HDD keeps locks up), and the more severe restarts/blackouts.

    Solution:

    Start -> Programs -> Toshiba -> Utilities -> HDD Protection Utility: Disable

    If you don’t have the utility, you can grab it from the Toshiba drivers website.

    – I’ve read about users having this issue even after reinstalling their OS. That probably wouldn’t solve the problem because the HDD Protection mechanism is built into the hardware, and unless you disable it through the Toshiba utility, even reinstalling OS won’t help.

    I have been using Toshiba M400 and after some months of use it developed a problem, couldn’t start freezes and fans runs high speed and LED blinks. To apply some pressure around 78 HJ keys and then start!… (ii)Tighten the nuts at the bottom of the Laptop and try….. Any suggestion on solving the problem will be appreciated.

    A fine line pattern and color display begins on the screen; then with hardboot, sometimes goes away, sometimes stays. I put laptop on hard solid hard surface, and pattern left then I could boot up. What is the fine line pattern that changes slowly to a bar and cycles back? I first thought it was a virus, but it seems something built into the computer hardware or software. It is not screensaver. compaq presario C769 Notebook

    Unfortunately, this sounds like motherboard related failure to me.
    You can try taking the laptop apart to barebone system and test step-by-step.
    You’ll have to disassemble it completely and leave only three major parts: motherboard, CPU and memory. After that test with an external monitor. If still nothing, it’s probably bad motherboard. I assume this is not memory problem because you said you tried replacing both modules.

    Thanks.

  27. I have a Toshiba L500, and Sometimes it will start with out failing, but sometimes it will stop on the windows logo and freeze, the fan will spin at full speed, and there is no hdd light, the only way is to do a head reset…..Although when it does start i can use it with out a problem.
    It also does the same thing when i log in and use it for a while. But it is completely random when it does happen.

    I have no idea what has happened

  28. I paid 1 lakh Rs for my XPS13 Ultrabook! BUT IT SEEMS TO HAVE PROBLEMS MORE THAN A NORMAL LAPTOP! Same screen issue as above, OVERHEATS in about 15 minutes of rainmeter use. Any way of solving the overheating (resulting in unexpected shutdown) problem???

  29. I have a Dell laptop, the screen started to flicker and slowly worsened. I took it to a shop and they reattached the cable in the screen because it was loose. In a few days it was doing it again and ten went black, however, it works perfectly when attached to an external monitor. The shop put a new cable on and a new vector board with no luck, then he ordered an entire new screen and still no luck. Now he is saying it must be my motherboard because he cannot find anything else wrong. Does that sound right, do you think it’s my motherboard?

  30. hello, i have a toshiba l655d-s5050 and it is only 2 yrs old, just out of warranty and i have a problem, The laptop will not start at all, I turn on the laptop and i hear the cd/dvd tray working but the hdd and the fans do not, there is no led on keyboard and the 4 lights on the bottom left of the laptop are on. I have also noticed orange stuff leaking from the battery and cannot afford a new laptop or battery at this time as i lost my job. Any ideas to help me get my laptop working.

    I have an hp pavilion dv6-1124ca and when a play any game for 5 to 10 minutes, my fans start to burn out and my screen show weird things like green bars. My fans keep doing a lot of noise and I have to press and hold the power button to restart it. Any clue about it?

  33. NvidiaGPUFailure

    You all suffer from the famous Nvidia GPU Failure, google “Nvidia class action lawsuit” and you will see. Solution for all of you, bake your mother board in the oven for 10 minutes at 400 degrees. I’m not kidding, it will reflow the solder on the GPU, but the problem will keep occuring. Google “GPU Oven reflow” and you will see. Good luck.

  34. Hi,

    Recently i change the display for the DELL laptop. When i carry the laptop in flight it drop from my hand. From then my laptop shows black screen i can see laptop boots as usual
    please give some solution

    Thanks in Advance

  35. My acer aspire one laptop is not responding on the screen.when i switch it on the fan does run and within 5-7 secs it stops without showing anything on the screen..the power button does show that its on but the hdd led is just off.help me pleaaaase coz i need to use it for my project

  36. Julian

    I have the same issue as the OP every once in a while. I just turn the laptop off and wait a minute before turning it on again.

    I was guessing it was an overheating problem because if I turn it off after a long intensive process (like running a minecraft server [laptop made in 1999 so that’s pretty intensive]) and I turn it on right away i get a black screen, but letting it cool for a minute allows it to boot up fine.

    Laptop is Toshiba Satellite L355D-S7901 (PSLE8U-02P01D. I am trying to fix it for a family not able to replace it at this time.

    I have already performed a FULL factory restore, wiping everything off the computer. It was working then seemed to become intermittint until currently not showing anything at all. I have tried using a 180lumens flashlight, and am unable to see anything on the screen (even faintly). It will see the external monitor every time and work. With no external monitor attached, I can hear the Windows startup sound and the shutdown sound after pressing the power button just once. It seems that the computer it’s self is working. When I use an external monitor and use the Fn and F5 keys to select which display I want, the system only shows the onscreen icon for the external monitor, there is no option for the LCD or both showing at all. Every function of the laptop seems to work just like new except for the LCD, I am able to surf the INet, use Office, Print, work with photos as long as I am using an external monitor.

    I am not sure where the problem rests, motherboard, LCD panel, (screen inverter), or if there is a descrete video card and it has a problem. I removed the keyboard and unplugged the display cable and the one that is directly under it, and plugged them back in (a few times) to make sure that they were not loose or just corrosion on them. Still no success.

  38. Help me please i have laptop of HP Pavilion dv 2000 one day my laptop is not showing the hard disk so i use Ubntu ,which run only on RAM only .After some day my Laptop do not work for Ubntu also and i closed the laptop for some day and now i want to start laptop but laptop screen gone black completely ,there is no booting process on screen but at the time of start up laptop lights on, fan sound is ok, power led blink but processor led continuously on…….please suggest me what is the problem in my laptop help me

    thank u…

  39. hi!! i am using sony via laptop …bt when i turn on my laptop the screen become totally blach but the fan is runing …i mean to say laptop turn on bt there is no display on screen??

  40. Questorfla

    Just to add my own comments to the mix. For those of you with the problem where” when you power off, the fan kicks into high speed and stays there till the battery goes dead”. I have the same issue.

    I am willing to try the RAM swap (I probably already did) but this seems to me something that is more related to power. The cooling fan has somehow found a way to route power around the Off switch and continue to run even when turned off. As for the reason for this happening I have begun to wonder about the battery itself or the charging circuit.
    Possibly even some kind of static electrical charge build-up.

    I have found that a quick way to “fix” it so you can at least work is to remove the battery. Run on just the charger. You will probably find (as I did) that the key to a successful startup is to press the power button at exactly the same second as you connect the power cable.

    This may have to be done a couple of times but it has never failed and saved this MSI from the scrap-heap.

    I would like to find a better solution, maybe one that would automatically flicker the power off /on until it “catches” if possible. Although this “fix” may depend on a full physical connect/reconnect to succeed.

    While running, the unit does not overheat and the fan runs at normal speed.

    Any comments of anyone else trying this would be appreciated

  41. Zach The Ultimate Programmer

    The main issue with it would be the motherboard or its video card

  42. SpongeLoad

    Hey Questorfla!
    I 100% agree with you.. I think that there’s problem with the battery. I take so much time to figure it out and FINALLY I decided to remove the battery and just plugged in my charger. IT WORKS!!!!

  43. T.TITUS

    thanks allot,
    however i still need your help!
    i have a laptop (Siemens)and my problem is that
    when i power on, i see nothing completely like light or any sound apart from the fan running at a very speed and it can not go off until the battery is down or just removed, please what can i do?

  44. Thanks friends, I have repair my laptop by reading your advice

  45. My Toshiba Satellite L6550-S5109 periodically turns off and a hard drive light goes out. Some times it happened after 1-2 min, some times after 1-3 hours. After this, I cannot turn comp on, only a fan works on maximal velocity. To turn my comp again, I need to stop/disable the fan and wait when the temperature of the processor increases and the screen lights again. Then I turn my comp off by using a power button and wait when the temperature decreases to normal. After these procedures, comp can be turned on.
    Probably, NvidiaGPUFailure was right when he wrote that “You all suffer from the famous Nvidia GPU Failure….” But how do we can fix this problem?

    I have Hp pavilion g6-1117tx laptop.

    Here is the laptop description available.

    In this i have a problem when i shutdown this it never shutdown. Laptop goes on shutdown mode but its fan remaining on and wifi button led remains on. It means it is not fully shutdown. Its doesnot stops till battery goes dead or by pressing the power button for more than 10sec. which is used to completely cutoff the power only in emergency mode.
    It is 2years old laptop.

    I want to get this out.
    Please help, as soon as possible.

  49. @ Rajat Makkar,
    Check the BIOS version installed. Updated the BIOS if necessary.
    If updating the BIOS doesn’t help, probably you’ll have to reinstall the OS.

  50. Hello everyone,

    I have an ACER AS5552-7819. It worked perfectly fine. Today, I unplug the external monitor and power and take my lap top with me to work. When I got to work and tried to turn my laptop on, I could hear the fans and everything, it sounded just like a normal boot but the display stayed off. This is what I already tried to fix this problem:
    1) removing battery and power and holding power button for 60 sec. Then putting battery and power cord back and trying to turn it on. I tried this a couple of times and nothing has changed – the lap top still sounds perfectly normal but its display stays off.
    2) Plugging in external display and toggling the display mode (Fn + F5 on my laptop). External display doesn’t register any input.
    3)Removing HDD. Still see nothing on the screen but can hear the fan from the lap top.
    4) Removing RAM and putting it back in. Still no change in the results.
    5) Turning the laptop on without RAM and HDD. I can still hear the fan and the lights turn on but the display is not responding at all.

    Is there anything else I can try? I found it strange that I couldn’t hear any beeping or any other feedback when I started the laptop in case 5. I would expect it to complain since neither RAM or HDD was connected. Instead, I could still hear the fan but no other feedback at all.
    Thanks for your help guys, I really appreciate it!

    pliz help me out! I have hp 2000 laptop but When is powered on, the screen remains completely blank and the cooling fan starts running at full speed till i power it off. what can i do?

  59. hemant

    yes, same i did , i also swap the RAMs and it started(sony vaio e series VPCEHEN….)
    thank alot guys,

    keep it up

  60. @ kato james,
    Try removing RAM modules one by one. If the problem still there, most likely this is the motherboard issue.

  61. Hello James,
    Please refresh your computer by using a CD/DVD having windows setup.
    Dont install windows but refresh the computer.thanks
