How to replace a processor in a laptop?

It is important to consider a few things before you open your laptop.  Install a new processor or How to replace a processor in a laptop? If the warranty on your system has expired, there’s no harm in trying it yourself.

When your warranty is still active, though, adding additional hardware would almost certainly nullify it.

Find a visual disassembly guide for your specific machine. Because not all laptops are manufactured (or assembled) equally, the processes for disassembling them will differ.

Before removing a single screw, double-check that the CPU you’re replacing is compatible with your Notebook. Because the processor is physically soldered on the motherboard. Certain laptops may not support processor upgrading.

If your laptop has detachable CPUs, the upgrade should be rather straightforward. Unfortunately, this is not the case on the vast majority of current computers.

The BGA connector is found on the majority of laptops. Because the CPUs have soldered to the socket, updating them is cumbersome at best.

How to check your processor compatibility?

Before going to check How to replace a processor in a laptop? It is important to verify the compatibility list on your motherboard. The manufacturers should have a list of compatible CPUs, so that’s a good place to start.

We’ll only be fiddling with these three machine sections during this procedure, making things nice and easy. A short Google search reveals the CPUs that this motherboard supports.

Intel also has a helpful tool for matching your CPU to your motherboard or vice versa.

If you look over the list, you’ll notice. You could easily upgrade from a Core i3 to a Core i9 processor if you had the money. Once you’ve determined what would fit, all that’s left is to find a place to buy the upgraded CPU.

Check that you have the correct socket (in our instance, LGA1151) before looking for something with a higher power. The Intel Core i7-8086K was our choice. Although not a significant performance improvement over the current CPU. It is ideal for demonstration purposes.

There we have different ways to replace a processor in a laptop;

Remove the Old CPU

If you’re upgrading your CPU rather than starting from scratch, you’ll need first to remove the old one from the system. Because the CPU cooler is impeding your route, your screwdriver will come in handy. It will easily lift off by turning the four screws in each corner, exposing the CPU to be replaced.

To remove the used thermal paste from your old CPU and the contact section of your cooler, use isopropyl alcohol and an antistatic cloth. If you get thermal paste on your hands, don’t worry. It will wash off. However, don’t allow any residue to remain on your clothing or your hardware.

Because the old CPU has clipped in, you’ll need to pull the lever to free it before trying to remove it. You can remove CPUs more easily than you can put them in, but the pins are sensitive. So it’s wise to take precautions. Put your old chip in an antistatic bag if you intend to reuse, sell, or give it away.

Set up the Computer

Now that your processor has been replaced, everything that follows applies to people installing a CPU into a new motherboard. It is nearly inverse of the previous step, so you may not expect that this step is as simple as it is.

Take the new CPU out of the packing and gently place it immediately into the seat with an empty socket and a lifting lever. You can only insert the chip in one direction; thus, use the corner indicators to ensure precise alignment.

You’ll need to lower the lever to lock the CPU into place once it’s fitted in smoothly. This shouldn’t take much force, and if you’re having trouble, double-check the alignment and then try again.

Use thermal paste

Although you should now have a fully functional CPU, you can’t simply reinstall your cooler and call it a day. How to replace a processor in a laptop? Use thermal paste is an important thing to do for it. To allow the cooler to do its job and, well, cool, you’ll need to apply a layer of thermal paste between them.

 Even the tiniest discrepancy can result in air pockets if the CPU and cooler heat sink appear to have flat surfaces. And, because air is a poor conductor of electricity, we’ll need thermal paste to fill the void.

Applying thermal paste is a contentious topic that has shattered friendships and tarnished the reputations of certain organizations. Still, there is one surefire way to get it right: squeeze a small blob over the middle of your new CPU, but don’t use too much. You only need something the size of a garden pea.

How to get start

However, don’t turn off your computer just yet. We’ll need to keep a watch on the chip-chiller as we start it up for the first time. Even if you correctly manage wires. Make sure fans aren’t obstructed, removing the side panel makes.  It is easy to perform further maintenance if we hit a snag, such as your PC not turning on.

When a problem like this happens, the first thing to do is double-check how tightly you’ve bolted down the cooler. Although it isn’t always as evident as symptoms such as warping, turning each screw half a turn. Rebooting may be a straightforward repair for your problem.

How to replace a processor in a laptop? If this doesn’t work, it’s possible that a component is to blame. Even the greatest gaming RAM may be fussy at times, and a simple reseating can fix various problems. To do so, release the catch on either side of the DIMM slot, then unplug and reinsert the RAM.

While you’re at it, double-check that all wires are securely connected and that none of the critical ones are missing.

Finally, the board will include a BIOS reset button or a CLR CMOS jumper. If you short this connection using a screwdriver or a jumper switch. The BIOS will be entirely reset to see if anything is causing problems.

The only other option is to retry the procedures in this article or return your new CPU, which may have been defective. If you took care of your old CPU, it should keep your gaming habits in check until you can figure out this mess, but hopefully, your PC started OK.

Troubleshooting and testing

If you haven’t been directed to the BIOS automatically after seeing the wonderful startup screen, press the DEL key to enter it. Find the ‘optimized default’ setting in the BIOS – it’s generally in the same section as ‘save and quit’ – and reboot your computer. The long-awaited Windows login page should finally appear.

Keep in mind that you may need to update your BIOS to make your motherboard work with the new CPU, so you don’t have to panic when your system doesn’t start.

Remove the Shell

Remove any screws that may be below the keyboard after it has been removed. Furthermore, if any ribbons or connectors are visible, these should be removed as well.

You must be cautious when removing the upper shell because there may be a ribbon cable or connector.

Remove the Display Assembly

You should do this step before another when you can see the base of the display hinges; it varies depending on the laptop.

Unscrew the hinges, disconnect the video and Wi-Fi antenna connections, and set aside the entire display assembly.

Use testing software

Now that you’re back in your PC and have a brand new piece of silicon at your disposal, you may as well put it to the test. You can go right into a game, but free applications like Cinebench R20. HWMonitor is available if you want to view the numbers.

Once Cinebench reaches 100% for all your CPU cores and threads. You can sit back in the best gaming chair and keep an eye on HWMonitor’s frequencies and temperatures. The temperature should not exceed 80°C. So your thermal paste may need to be redone.  You may have to replace your cooler and CPU.

That’s all there is to it unless you want to learn.  How to overclock your CPU for maximum performance securely. We’ll help you get gaming quickly. If you need to know how to install a graphics card or power supply to give your chip the extra juice it may need.

How to Reuse a Laptop Processor?

Using an older laptop for home projects is a great way to find new uses for it. There are hundreds of tutorials online for turning a laptop into a home server, a Wi-Fi hotspot, or a video streaming device similar to the Roku or Amazon Fire TV stick.

You might be able to get a good price for the laptop if you sell it or give it to a family in need who can use it for starter computers or business purposes.

Advantages of replacing a processor in a laptop

How to replace a processor in a laptop? While AMD (Advanced Micro Devices), Intel’s major competitor, offers competitively priced, high-quality components. There are a few reasons why an Intel CPU may be preferable for your needs.

Production of Heat

While AMD and Intel frequently swap places depending on whatever performance benchmark you use. Intel CPUs have known for generating less heat. Thanks in part to reduced wattage requirements, such as their netbook parts. Intel may be a superior choice in a small environment, such as a minicomputer.


Because Intel processors are more widely used, a greater choice of motherboards is available. This means you have a wider range of features to pick from. It’s easier to get a lower price than an AMD-compatible motherboard.

Power Consumption

Intel’s Atom CPU for netbooks consumes very little power—as little as 5 watts. A comparable AMD CPU may consume two to three times the amount of electricity, affecting the battery life of a netbook.

Memory Controllers with Integrated Memory

During this time, each core of a CPU has coordinated to work together.  Temporary information has been stored and retrieved more successfully.

Intel’s shift to QuickPath Interconnect put it on par with AMD in terms of memory performance. Intel’s strong Core i7 processors combined with this technology allow for even better performance.

Fabrication Capacity

Intel has 15 CPU fabrication factories across the world. But AMD has spun off a small number of units into a separate company that is majority controlled by a third party. Intel’s increased production capacity helps them deliver a bigger number of CPUs to market in less time.  Increasing your chances of finding the CPU you desire.


Hope you get the answer to How to replace a processor in a laptop? According to popular opinion, you cannot change your CPU’s mounting type if it is BGA.

The processor is permanently linked to the motherboard in BGA installation. Small solder balls are under the CPU for this purpose, and the motherboard features small solder pads. As a result, swapping out a BGA-based Core i5 processor for a BGA-based Core i7 processor necessitates a high level of experience and equipment.

If the socket types are identical, it should be possible to upgrade a Core i3 or Core i5 to a Core i7.
