How to Replace a Laptop Circuit Board

From upgrading your computer to replacing damaged components, there are several reasons why you’d want to replace a laptop circuit board. Some laptops are a bit easier to work on than others, as there are some laptops designed to remain intact. However, with some straightforward instructions and tips, even if you’ve never worked on a laptop before you should be able to replace the laptop circuit board without too many issues.

Buy the Correct Circuit Board

Before you can replace the current circuit board, you need to make sure you have the appropriate replacement board. Look up the exact computer system you’re currently running. This is found in the “About This Mac/Computer” section on the computer. This area will tell you exactly the kind of equipment you’re running. You’ll also identify the kind of circuit board you have in the laptop so you know what to purchase.

Know Your Warranty

It’s possible the current warranty on the laptop covers the need to replace its circuit board. So check this ahead of time. Additionally, understand that taking apart the computer on your own likely voids the warranty, so take extra care ahead of time.


You’ll need to pick up the right kind of tools. The inside of your laptop uses often unusual screws, so unless you have a toolkit designed for working on a laptop, chances are you won’t have the correct tools on hand. Pick up a computer toolkit. This will come with severalĀ different micro screwdrivers. Some of these drivers look like little starbursts with the number of edges on it. You’ll also want a static bracelet. Static electricity can instantly short out every single component within your laptop. You’ll want to take precautions here. For starters, make sure you touch something metal before working on the laptop. This clears your static charge. This bracelet has a metal clip to it. Clip it onto a piece of grounded metal. The grounded metal will absorb any shock and keep it from encountering your laptop.

Remove the Pieces Slowly.

Laptops are put together soundly. This often means there are screws hiding in places you didn’t even know existed. It is helpful to have a diagram with you while taking it apart. Some screws are tucked away under grips on the underside of the laptop, within battery ports and several other locations. If you try to slide a component out and it doesn’t give, do not pull on it. Chances are there is another screw you haven’t seen or removed yet.

Once you have the laptop open, take time in removing the different screws. As you’re replacing the circuit board you’ll need to disconnect just about everything. Begin by disconnecting the battery. With the battery out, you can start to remove other components. As you remove the screws it is best to place the screws in containers you can mark. This way, when it comes time to close the laptop back up again you’ll know which screws go where (depending on the laptop you’re working on there may be a half-dozen different kinds of screws used, and you don’t want to apply the wrong screw.

Close but Don’t Tighten

Before you place the case of the laptop back together and fasten everything back to its pre-work condition, test it out first. You don’t want to try and fire the laptop up only to find something not working. You’ll end up taking the screws in and out, which increases the chance of stripping the screws. Test out the power before locking the laptop down. This way, when you know it powers on you can then go about securing the laptop and closing it all off. Make sure every single screw goes back into theĀ laptop.

Just about any work, a repair shop does on a laptop can be done at home. It may take you more time as you’re not as familiar with the system, but you’ll save a considerable amount of money off the cost of repairs. Whether you want to upgrade the system or repair it, make sure to follow these specific tips throughout the circuit board replacement process.
