Laptop Motherboard Failure Symptoms And How To Fix It?

Laptop motherboard failure symptoms may occur if your computer suddenly stops working. Unfortunately, they’re also among the hardest computer parts to repair or replace.

One of the priciest parts found in laptops and desktop computers is the motherboard. You must look for a suitable motherboard that can be utilized with the hard drive, processor, RAM, and other installed components if you need to replace the motherboard because it has been damaged in some way. That procedure is never enjoyable. Most consumers choose to purchase a brand-new laptop or computer rather than attempting to fix their old one.

What causes Laptop motherboard Failure?

Here we’ll discuss what causes motherboard failure:

1) Power fluctuations

There is a greater risk of motherboard damage if the motherboard in your laptop or computer is experiencing power fluctuations or spikes. Since the motherboard only operates on DC power, if your power supply malfunctions and instead supplies direct AC current or highly fluctuating AC current, the motherboard may be damaged.

Use a high-quality surge protector to protect your motherboard from electrical surges and oscillations.

2) Dust particles

If you don’t regularly clean your laptop or computer, the motherboard can accumulate dust particles, which can harm the CPU’s IC and block the processor fan, shortening the lifespan of the motherboard. Switches and contacts on the motherboard might become damaged by corrosive dust.

3) Due to overheating

The temperature of your motherboard may rise for a variety of causes, including dust and voltage fluctuations, eventually overheating the entire system and producing an unpleasant smell in the motherboard, which is a sign of a defective motherboard. A motherboard may overheat due to CPU and motherboard fan blockages. Most current computers and laptops will automatically shut down when they get too overheated.

Use heatsink paste between the CPU and processor fans to stop it from happening. regularly clean the motherboard. Utilize software for temperature alerting and recording. Make use of the laptop in the cool space.

4) Physical damage

If your laptop or PC is dropped to the ground, the motherboard’s electronic components could become loose and be harmed because the motherboard may have moveable parts and components attached to it. Also, it might result in a motherboard short circuit. Transistors that have burned out or circuits that have been damaged can all result in catastrophic motherboard failure.

5) Aging

Each electronic device has a lifespan. They aren’t indestructible. Similarly, the Motherboard will be increasingly vulnerable to damage as it ages.

It is preferable to replace the motherboard with a new one if the current one is in poor condition

6) Liquid Damage

There is a possibility of the motherboard short-circuiting out if any liquid spills on it. This will harm your entire computer system, not just the motherboard.  Furthermore, liquid destroys the motherboard by triggering a chemical interaction with the circuit board and another internal component.

Better avoid bringing liquids close to your laptop or computer. Additionally, turn off your system right once liquid spills on the motherboard.

7) Manufacturer Design Issues

Cheap motherboards are more susceptible to malfunction. Most cheap motherboards have cheap components added, some of which may not be properly built. This could lead to cooling problems.

8) Due To Lightening

Faulty motherboards can potentially be the result of lightning. Lightning will also have an impact on the electric circuit board. It is a natural process against which it is hard to protect devices.

9) Use Of Incompatible Hardware Component

The usage of incompatible and low-quality hardware parts, such as RAM, HDD, CPU, PCI chips, CMOS batteries, and graphics cards, may cause irregularities and have a negative impact on the motherboard and other hardware parts.

Laptop Motherboard Failure Symptoms

Here, we’ll discuss HP and Dell laptop motherboard failure symptoms one by one.

Let’s get started.

PC or Laptop Failing To Boot:

It is a sign of a damaged motherboard. It’s possible for the motherboard to become slower as it approaches death. Your system might take too long to start up, or the apps that are necessary to work properly might load more slowly. In either case, it is not difficult to spot this slowdown.

Laptop Blue Screen Of Death:

Hardware issues frequently result in the Blue Screen of Death. However, there may be a number of additional factors. If your computer displays a blue screen with failure messages and error codes when you turn it on, there may be issues with numerous components like RAM, HDD, and even the motherboard. Some motherboard manufacturers will also indicate the issue’s root cause. You may really conduct a google search for the problem code to determine whether it relates to the motherboard.

Computer Or Laptop Freezing:

Another unpleasant sign of a failing motherboard is computer freezing. Your computer will run the program fine when you turn it on, but as soon as you start using it again, it will freeze. Computers freezing up can have a variety of causes. The problem could be hardware- or software-related.

Computer Randomly Restarting:

This is one of the most commonly experienced symptoms of a failing motherboard. For a number of reasons, such as power supply issues, malware, overheating, or driver issues, your computer might suddenly restart. Additional factors include issues with heat, dust, dirt, hair, and blasting viruses.

Physical Damages:

A failing motherboard often shows physical damage, especially when the capacitors are blown out. The motherboard’s capacitors will expand larger than normal as it begins to overheat. A blown capacitor can be easily changed, but only in certain circumstances. Precision soldering is necessary for this.

Hardware Not Recognized:

When power isn’t supplied to hardware properly, it can sometimes cause USB ports, audio ports, mouse ports, and other internal components including RAM, CPUs, graphics cards, CMOS, and BIOS to fail. It can signal a faulty motherboard.

Burning Smell:

You should shut down your computer right away if you happen to smell burning coming from it. This indicates that the motherboard within the computer has reached its maximum level of overheating and should not be used any longer. Even so, if you keep using the motherboard, it can also affect other parts of the system. Typically, this is brought on by short circuits created by the connection of unsuitable components to the motherboard.

Showing BIOS Menu:

Your computer’s setup utility menu is called the BIOS Menu. If it shows up on its own during the startup procedure, it means the motherboard isn’t working properly.  The BIOS will be visible once the machine tries to boot because it controls all of the hardware. Additionally, keep in mind that other components may be to fault instead of the motherboard itself if the BIOS menu appears.

Slow Down Performance:

Your computer’s performance may degrade if your motherboard is too old. For instance, your PC can take a while to start up.

Beep Noises:

Your BIOS’s beep patterns can be used to help us identify the hardware issue. Repeated beeps in the Award BIOS indicate a memory problem. The motherboard’s memory or memory slot may have issues.

Capacitors Bloated Out:

A failing motherboard most at times shows signs of capacitors bloated out. The motherboard’s capacitors will expand larger than usual as it begins to overheat. Due to their tendency to overheat, older motherboard models exhibit this more frequently. A blown capacitor can be easily changed, but only in certain circumstances. This necessitates precision soldering. This is one of the laptop motherboard capacitor failure symptoms.

How To Diagnose Laptop Motherboard Problems?

Motherboard problems are the most difficult issues to diagnose. The motherboard houses many components, hence a variety of things can lead to faults. One of the most helpful tools for motherboard troubleshooting is POST (power-on self-test). Any codes that appear on the screen should have their meanings searched. If more than one POST error code appears, you should analyze them sequentially. The list below provides assistance with motherboard diagnostics:

  1. Is there power flowing to the motherboard? To see if the fan is running, check the power source. Check to see if the fan on the CPU or motherboard is running. Verify the voltages connecting the motherboard to the power source.
  2. Check the BIOS settings
  3. Inspect for overheating. Turn off the computer’s power and give it time to cool. Remove the computer’s cover and turn it on.
  4. Be sure to look for swollen capacitors on the motherboard. These are tiny parts that could seem to be swollen. If sighted, replace the motherboard right away.
  5. Reinstall the memory chips, adapters, and CPU.
  6. Remove the unnecessary adapters and devices before starting the computer.
  7. If it’s possible, connect the computer to a different circuit and power outlet.
  8. Determine if the motherboard is shorting out on the frame by doing a test.
  9. Check the CMOS battery
  10. Check the output on a motherboard equipped with diagnostic LEDs for any error codes. For information on the issue and potential solutions, consult the motherboard documentation or online resources.
