How to Replace Motherboard on Laptop Easy Guide

Suppose the motherboard in a laptop dies and the machine is still salvageable. In that case, you can purchase replacement components and possibly even improve the unit in the process (depending on the model of the laptop). 

While locating a new board may be difficult, some online auction houses and traditional stores carry OEM replacement components, as well as secondhand parts extracted from otherwise damaged computers. Once you’ve got the motherboard, you can use this guide to How to Replace Motherboard on Laptop?

What Causes the Death of a Laptop Motherboard?

There are many possible causes of motherboard failure, but the most prevalent is excessive heat. Heat degrades all hardware components over time, but it mustn’t destroy the motherboard, as this is where all the other members are connected. That is why heat dissipation is critical, even more so if you are overclocking fans, heatsinks, and liquid cooling are all necessary.

Overheating is a more significant concern with laptops due to their small chassis and closely packed components. Still, whether you’re using a computer or a desktop, all those cooling methods will be ineffective if you don’t periodically clean your PC. Too much dust will eventually clog the ventilation system of your computer, both in the chassis and in the components, causing it to choke on hot air and filth.

Additionally, motherboards can destroy by improperly connected or partially connected cables, inadequately seated components, and electrical spikes and power surges. All of those, however, are easily avoidable. Whether you’re constructing or purchasing, take your time assembling your PC, and ensure that your PC and peripherals are connecting to a decent surge protector.

How Can I Decide Whether or Not My Motherboard Is Dead?

Motherboard failures are notoriously tricky to identify since they exhibit many symptoms as other component failures. When the motherboard on my current laptop failed, the entire system shut down, and I could not restart it.

Thus, one telltale indicator is if you press the power button on your desktop or laptop and your computer does not power on, or if your computer goes down unexpectedly. It is not always an indication that your motherboard is dead; it is also possible that your power supply is slow, your CPU overheated, and your computer shut down as a fail-safe. 

These are some of the first things you should examine before disconnecting anything from your motherboard. The simplest way to test your power supply is to connect it to a completely functional system and turn it on. If it does not work, the problem is with the power supply, not the motherboard. 

(Alternatively, if you have another working power supply laying around, you can use it on your PC.) The battery may be entirely dead for laptops: plug your computer into an AC adapter and switch it on. If that works, you can rest assured that the motherboard is in good condition.

However, if your computer continues to fail to boot or shut down randomly, you may receive a beep code when the BIOS attempts to POST (Power On Self Test). Each motherboard manufacturer uses a unique set of beep codes to indicate various hardware failures, and you’ll need to consult your user manual to determine which codes to use, as a PC can fail to POST for a variety of reasons, including a failing CPU, RAM, or even storage. 

If your computer does not POST and the motherboard’s power LED is not illuminated, this is another red flag. Of course, you’ll want to conduct a visual inspection to ensure that there are no bent, bulging, or blown capacitors, as this is another telltale sign that your motherboard has sent to the great repair shop in the sky. If anything smells like it is on fire, this is another indication.

How to Replace Motherboard on Laptop?

Now, I will tell you all about How to Replace Motherboard on Laptop? 

  • Consult the laptop’s owner’s manual for complete instructions on removing the optical drive and complex disc components.
  • Remove the laptop’s power line and batteries.
  • Near the laptop’s lid and invert it onto a Good work area.
  • By moving a grounded metal surface, you can discharge any static energy present in your body.
  • Remove any screws or other fasteners that hold the optical drive and hard drive in place. They would be removed from the laptop and kept aside.
  • Remove the memory access cover by rolling it. (For its placement, refer to the handbook.)
  • Remove each module by loosening the clips that secure the memory chips in place. Frequently, the memory chips are positioned beside the mini-PCI wireless card. We will use Memory chips approximately half the size of a mini-PCI card.
  • If a wireless card is present, disconnect the antenna lead from it. Remove the card by releasing the clamps that secure it.
  • Open the processor access door if your machine has one. Remove the CPU if it is removable and does not come with the new motherboard. Set it aside in a safe location.
  • Begin unscrewing all of the screws that hold the machine’s bottom case together. They are pretty small and quickly stripped; therefore, use the adequately sized screwdriver for the job. Do not detach any screws that secure the LCD screen to the machine unless required.
  • Open the case with caution. There may be hide clips that will break if required open. The keyboard may need to be take off or elevated out of the way on some machines.
  • Before disassembling anything else, sketch the component positions. It will assist you in adequately reassembling the equipment following the work.
  • Disconnect all wires from the motherboard. Unplug any cards that do not integrate into the motherboard, such as the video card. Locate and unscrew the motherboard’s mounting screws.
  • Remove the manage motherboard, replace it with the new one, then rebuild the components in reverse order.
