How to Diagnose Laptop Motherboard Problems

The only housing which binds together all other hardware parts is a motherboard. It’s the first and final hardware system in its entirety. The performance of each hardware part is linked directly to the Mboard on which it has installed. Several issues may arise from a faulty or damaged laptop motherboard. A defective power supply is a significant cause why laptop motherboards are damaged. 

Fluctuations in power supply and spikes may easily harm your computer’s Mboard, in addition to typical Notebook board problems. There may be problems because of a fabrication fault, such as electrolytic condensers leaking. In some circumstances, you may not repair your Motherboard. The only option in such cases is to replace the laptop motherboard.

After reading or utilizing our below-mentioned information the need to search How to Diagnose Laptop Motherboard Problems. will definitely be elevated.

Motherboard Failure Signs:

  • Not booting
  • Errors in Blue Screen
  • Freezing and hardware no longer functions randomly
  • Audio and laptops do not function
  • Connected devices are not working

Reason for Motherboard Failure:

 How to Diagnose Laptop Motherboard Problems

Now that you have verified that your computer’s Mainboard fails, you may ask what causes such a problem. Now, some of the frequent causes for a Mainboard to cease functioning are below:

Electrical Spikes:

An electric spike is a short-lived explosion of energy in an electrical circuit. It may be the consequence of power-hungry devices, electrical wiring issues, power supply difficulties outside the home or lightning strikes. Lightning is the #1 blame for the spike/surge motherboard failure that we encounter and is frequently used via Coax / Telephone Line / Ethernet port and bypassing an emergency protector! This rapid voltage fluctuation may harm the sensitive circuitry of a motherboard.

Fan Failure: 

Fan failure. Dust may very quickly build in fans that cause them to fail. Make sure you clean the fans at least once a year inside the tower.

Dust Contamination:

Dust, pet hair, and foreign particles may be a definite assassin of the Mboard. When they accumulate in your machine, the air circulation that keeps the machine cold begins to be blocked. It’s like dangerous fat clogs your heart attack arteries.

Smoke and Perfume:

Cigarette smoke tar is not suitable for your health or your computer’s health. Cigarette smoke creates a sticky, gooey material inside a computer when mixed with dust. Other aerosols like hair spray or perfume may have the same impact in addition to cigarette smoke.

If it is enabled, remember everything that floats through the air will end up inside your device. All of these things create a sticky residue that may collect dust and other external contaminants. And it’s also tough to remove. You should have a regular program to clean the inside of your computer and attempt to keep it away from these things.


The Motherboard may overheat if several activities are carried out concurrently, and the power supply runs at full output constantly. It is recommended to give your computer regular rest if you play, play video, watch videos, etc. In certain instances, there may also be overheating owing to variations in the power supply or in one portion of the circuit board.

Use In Random Position:

Ironically, a laptop may cover intakes and exhaust fans on your lap or a soft surface. Overheating may be avoided with a precise fan basin, relax after heavy usage on your computer, use your laptop in the more relaxed rooms and use it on a cold hard surface. May install Software for temperature monitoring installed inside to monitor your computer temperature.

Accidental Fall of Laptop:

An unintentional impact on your Mainboard may cause significant circuit damage that can lead to motherboard failure. I quickly saw motherboards fail due to the effect of dropping. Usually, a component affects the board regions that did not intend to touch and create a brief space of time. Damage caused by spills is also widespread.

By Knowing all these reasons there is no need to further search about How to Diagnose Laptop Motherboard Problems.

Diagnosing the Motherboard Problem:

Two troubleshooting categories are typically used by a user or professional to resolve a faulty board. The first checks if the machine performs POST and continues to boot, while the second checks whether the system can no longer do POST or not.

POST is essentially a diagnostic test conducted on the BIOS of your board to verify if peripherals like hard drives, video cards, RAMs, keyboards, or mouse are connected or not. BIOS loads the operating system if the necessary peripherals are recognized.

Hope so you get the answer to the question How to Diagnose Laptop Motherboard Problems.

The lifespan of Motherboard:

The typical life of a laptop motherboard is around 50,000 hours. Beyond this period, a failure of the motherboard or a laptop motherboard issue is expect sooner or later. Moreover, this lifetime is only applicable if you don’t want to spend it repairing your laptop board.

Now, when a defective motherboard arises because of aging or wear and tear of integrated chips and other passive electrical components, you have two choices. Either take a laptop and visit a reputable laptop motherboard repair business on-site, or purchase a new one supporting your current system to replace a laptop motherboard in your area.

Checking Of Motherboard Failure:

Check Your Monitor:

Maybe your display isn’t powered on? Make sure that your video cable is linked correctly and there are no loose connections via disconnecting and reconnecting the cable.

Check Your Hardware Graphic:

If you connect to your Motherboard using a graphic card, remove it, click the video wire on your display to the Motherboard, and restart your device. If your laptop boots without any problems, you have to fix or replace a broken graphic card.

Check Your Hardware Internal:

You may put extra hardware on your laptop. A motherboard needs the following to function appropriately: RAM, Processor, Fan and SPMS. You may try removing the additional hardware to see if the problem is there. You may switch on your laptop once removed and check whether it boots correctly. If so, this means that one of your internal hardware systems has a problem. May test each component to determine which one must be separated or replaced.

Check Your Hig Your RAM:

A frequent problem with your Mainboard is that your RAM (random access memory) is dead. Therefore your Motherboard doesn’t function. If you have two RAMs, test each by removing one and activating your computer. If the issue is the RAM, then the RAM must be repaired or replaced.

By doing all these steps carefully there is no need to further search about How to Diagnose Laptop Motherboard Problems.

Is it possible to fix a damaged motherboard?

If your laptop isn’t turned on, it could be due to a defective motherboard. However, there are numerous situations in which may fix a motherboard. In other instances, you may replace the Motherboard without changing your other components, saving a lot of money.

FAQs – How to Diagnose Laptop Motherboard Problems?

  1. How Can I Test to See if My Motherboard Is Bad?

    Perhaps the battery is totally dead for laptops: plug in your laptop with your AC adapter and attempt to activate it. If it works, you know that the Motherboard is all right. However, if your system does not start or shut down unexpectedly, you may receive a beep signal when the BIOS attempts to POST (Power On Self Test).

  2. How Long Does a Motherboard Last?

    A standard computer motherboard may generally live between months and decades. It will most frequently function for 10 – 20 years. Tip: To preserve your Motherboard longer, you should be careful not to do activities that destroy your hardware.

  3. What Causes Motherboard to Fail?

    Excessive electric shocks, physical damage or extreme heat are among the most frequent reasons for motherboard failure. Some of these risks are unavoidable and, depending on your computer model, may vary in probability.


The Motherboard is the most sensitive part of the laptop. Our laptop can stop working or become slow with a slight issue in the Motherboard. So if you want to know that How to Diagnose Laptops Motherboard Problems, then the above information will help you.
