How do people update a laptop CPU

Is it possible to upgrade my laptop processor?

Is it possible? Probably yes or no. Since you asked that question, I suppose. that you are an advanced PC / laptop user. But laptop CPU (Processor) / GPU (Graphical Processing Unit) upgrade depends on the type of CPU / GPU socket of the motherboard. There are entry-level, mid-range, and high-end laptops on the market and each of them has a very specific type of hardware. High-end laptops have full upgrade potential of RAM modules, hard disk, CPU and graphics card. CPU in high-end laptops (and some mid-range ones) are attached to motherboards by a removable socket, so you can easily remove chip by turning a screw on the socket. Entry level and mid-range laptops on other hands has limited upgrade potential, there are CPU and GPU chips mounted as "on system chips", it means, that CPU and GPU, and sometimes even RAM chips are soldered directly onto the motherboard via a BGA (Ball Grid Array) type socket.

An ordinary PC user cannot remove this type of CPU and GPU from the motherboard socket by himself without specific knowledge, tools and hardware. The only option you have in this case is to upgrade the RAM (not in all cases) and hard drive (mechanically with Solid State Drive). But in theory anything is possible if you have enough motivation and some money. An experienced professional can do this for you, but it also runs the risk of permanent damage to the laptop's hardware, e.g. B. System board burns caused by heat damage.

There are some high-end soldering stations, designed for melt up socket, that allow you to do on chip level repairs, heat up and remove CPU and GPU chips from the motherboard and replace with other, more powerful ones. This job requires high skills from professional, continuous monitoring of the board temperatures and precise guidance of the laser-controlled soldering process. It's like brain surgery for laptops. Even if you're lucky, an updated GPU seldom lasts more than two years, and a CPU can last much longer.

In addition, there are mostly compatibility problems. You need to choose a very specific CPU range for your motherboard. The same class and model of laptop / ultrabooks can also have different system boards, depending on the chips they use. Unsuccessful CPU soldering and booting can lead to problems with BIOS conflicts, underperformance, processor overheating, some system crashes, blue screen of death, boot loops, etc.

The most common problem with the BGA socket CPU fix / upgrade is overheating. A more powerful CPU generates more heat (for example: 35 watt mobile i7 quad-core CPU versus 6 watt Pentium quad-core CPU). A heat sink designed for a weak, lower TDP processor cannot properly dissipate more heat generated by a more resolved, more powerful CPU. You will probably also need CPU undervoltage (if the BIOS settings allow it), install a more powerful fan, flash the BIOS with the latest version or flash with a modified BIOS, use a graphics card driver for the new GPU chip. Such an upgrade is a time-consuming, dubiously inexpensive, and very complicated process.

This is why most people answer your question NO, no one wants to boost expensive hardware. One mistake in the soldering process will turn your laptop motherboard into a useless piece of junk. In addition to all of the above tasks, such a chip level upgrade would void your warranty agreements and all work is done at your own risk. After the upgrade is over, it is mandatory to regularly tear down your modified laptop and clean it of dust that has accumulated in heat pipes and fans, and change the thermal grease on CPU and GPU units every other year.

If you are ready to take on this very risky job, good luck! I hope I've answered your questions the way you wanted me to.
