But before you conclude, thoroughly assess the motherboard damage, for you need to decide between two options laptop motherboard repair vs. a new laptop.

Signs of Motherboard failure

  1. You have switched on the computer being indicated by the light and fan also starts to spin. But there is a complete blackout on the computer screen with the hard drive not working within 10- 15 sec.
  2. The initial start-up functions appear like indicative light, fan, and hard drive sound, but disappears after a while, i.e., 5 – 3 minutes.
  3. A high pitched sound comes from the laptop when you press the “on” button.
  4. The last one can be that even when you have switched on the computer, nothing happens.

Causes of Motherboard failure

There are numerous reasons why a laptop’s motherboard would fail. But some common and often unlooked corners include:

  1. Electric and voltage fluctuations
  2. Dust particles, smoke, laptops age
  3. Fan failure often causing overheating issues
  4. Crash or physical damage

Even the signs of motherboard failure mentioned above need to be looked into; there are some exceptions to be looked when checking for laptop motherboard damage and they include:

  1. The black screen could be an indication of a possible backlight problem. In-between the hinges there is a button which acts as an on/off switch for the laptop’s backlight. This buttons automatically get switched off when the lid is closed. However, sometimes it gets stuck. Therefore first pull the laptop’s lid back and forth, if it is still the same then take a pin, find the switch and gently tap it. If even this doesn’t work, possible you need a laptop motherboard repair.
  2. If your laptops get switched on for a few seconds and then dies out, it could be due to the battery being exhausted. First connected to the power outlet and then switch it on. Also check for connection cables, if it still not works there could be two reasons. First, your adapter might have been damaged, get it checked. If that’s not the case, then the possible failure could indicate a laptop motherboard repair.
  3. Often resetting the RAM and CMOS or updating the BIOS could save you from motherboard laptop repair.

    This article seems like it is for the sole purpose of giving a link to a business for repair services instead of anything useful. I would think launching the manufacturer’s diagnostic utility to run tests would be a good thing to do first. Then you can determine if you have hardware or OS problems.

    I agree that the title is misleading, as in not accurate at all for a title. However, for the trolls that are griping/whining with their insults, remember the saying, “if you don’t have anything nice to say, don’t say anything at all”. What is the point in stating that this article sucks? Where is their link to better information? Here’s mine…

    Mobo failures:
    1) water damage
    2) overheating
    3) short circuit
    4) wrong voltage


    1) won’t boot, some laptops can show diagnostic lights or sounds
    2) cpu runs really slow
    3) blue screen randomly

    How to fix?

    1) I’ve heard people clean and dry water damaged motherboard with success
    2) Replacing mobo is not very complicated as least for DELL
    3) Sell it to someone who knows how to fix, buy a new laptop

    I am a computer repair tech. What is this a guide for? There is nothing on repair and only remedial troubleshooting. Come on, man.

    If your computer does not power on it could be a number of things. Most of the time ‘motherboard’ issues are from component failure. Often, the component can be replaced or even bypassed to restore functionality.

    Your list of tell-tale’s list only indicate a problem, not necessarily motherboard failure. Desktop computers rarely suffer motherboard failure. Laptops fail because of overheating.

    You can avoid most laptop failures with a good cooling station. I usually make my own or repair the ones I find in the trash. Fans from old desktops are great for this.
