For many years, I wished I could upgrade laptop processor from i3 to higher like i5 or i7.
Earlier, I thought laptop cpu upgrade is impossible. After all, every laptop service center told me the same.
In this post, I’ll show you how I performed a laptop processor upgrade and replaced my Legacy Intel i3-2330M processor with i7-2640M in my personal laptop.(Samsung NP300E5Z)
I bought my first laptop in 2011 – Samsung NP300E5Z-S01IN. 😀 It was a pretty good, above average ‘value for money’ at that time.
Almost close to a decade now, I’ve upgraded my laptop in every possible way to perform at par with today’s standards: 👍
☠️ Be Diligent ☠️
WARNING:- It is common sense that you don’t attempt to upgrade laptop CPU if it is still under warranty or you have no clue about circuits, motherboard and other jargon.
Consequently, I take no responsibility if you brick your device! – Do it at your risk.

Here’s a summary of all the upgrades so far to my Samsung NP300E5Z
(I manually replaced)
|Purpose of upgrade||Cost of upgrade|
|RAM||4 GB (ADATA)||+4GB = 8GB||Faster processing||₹ 1,200|
|Hard Disk||Hitachi – 1TB – HDD||Samsung 750 EVO SSD -120 GB for OS|
Crucial MX500 – 500 GB for storage
|Faster File operations (Open, Read, Write, Move etc.)||₹ 3,000|
|CD/DVD slot||Optical disk tray||Replaced it with default Hitachi 1TB😊||Secondary to primary Storage||₹ 300|
|Thermal Gel||Default||Thermal Grease||Processor cooling, Less power consumption||₹ 150|
|Processor||Intel i3- 2330M|
2.2GHz, Dual core, 4 Threads
2.8GHz – 3.5GHz Turbo,
Dual Core, 8 Threads
|Overall performance boost||₹ 3,800|
It is a considerable investment. However, for a price of almost ₹13.5K, I’ve got myself a laptop that can easily beat a new one with triple price tag. (especially if it’s from HP 🤪). Therefore this effort is worth it..!👍

On the other hand, the last row of the table – ‘Processor Upgrade” – I thought could never be done for my Samsung NP500E5Z.
However, not just the local service centers but the service centers of these ‘multi-billion dollar’ companies told me out-right that it’s not possible to replace a laptop’s processor.

Firstly, with an obsessive wish to upgrade laptop processor, hours of research and bit of a luck (which favors the one who works for it), I was able to do so.
Secondly, the results? – Are very satisfying. ❤
So, how to upgrade a laptop processor? Although, this post illustrates processor replacement of my particular model of laptop, (Samsung NP300E5Z), it is not limited to it.
Any laptop and hence, any brand can be upgraded- provided you do your due-diligence. 👈
Step 1: Check if your CPU is up-gradable.
Before you do a laptop cpu upgrade, you can either go to your computer >> This PC >> right click >> Select properties and view processor details there.
Use a tool like ‘CPU-Z‘ to see your processor type.
I recommend latter because there is much more you can know about your motherboard, processor etc. CPU-Z is of great help.
NOTE:– If your processor is a mobile processor i.e., of type M or QM, then you can perform laptop processor upgrade. According to my limited knowledge, if your laptop processor is of type U, then you can’t replace it. Sorry!! – Wait, may be you can but I don’t know!
Step 2: Check the motherboard socket type to replace laptop processor.
Mine is Socket G2 / rPGA988B and processor is Sandy Bridge architecture. Which means, you need to replace this with a processor compatible with this particular socket and micro-architecture.
Step 3: You need to get technical. – Find a compatible processor to upgrade.
There are plenty of resources online. They even show probability indicators of success rate of replacement. I used this one:- cpu-upgrade.com/i3_mobile.
Though there are plenty of tempting QM (quad cores) , I wanted to go with same wattage (power) and wanted to be on safer side.
There is also websites that’ll give you an approximation of comparative performance. Like this one – Versus.com/i32330mvsi72640m
Tip:- It is best to replace a processor of certain wattage with same wattage processor. The L1, L2, L3 cache can differ and it is good if high, but I’m not sure on wattage.
For Example:– Intel core i3- 2320M requires 35W power socket. Hence, I chose i7-2640M which also requires 35W power socket.
Step 4: Just do it!
Dismantle your laptop, find the processor and replace it. There are plenty of YouTube videos which show how to dismantle a laptop correctly. Find your model.
You will require a tool set with mini/micro screw-drivers.
Don’t forget to apply thermal gel/paste.
You’ll also have to install a new Graphics driver – Intel Graphics for your processor.
Here’s the Satisfying part after replacement. I’ve used Novabench to run tests.
Performance comparision of my laptop processor upgrade [Samsung NP300 E5Z]
Yep. An increase of 38% – in benchmark score. What about the real application test you ask?
Honestly, it is not a mind-blowing upgrade. Though the difference of this laptop CPU upgrade is definitely visible, it is not over-whelming either.
I feel I should have gone for a Quad core processor but I wasn’t sure and didn’t want to risk money and laptop! So, considering that, I am overall happy!

Before and after of laptop processor upgrade (in my day to day activities)
- On my Windows 10, boot up time, i.e., from windows logo to till I see login screen, it used to take 8 seconds before. Now it is 5 seconds!
- The laptop fan doesn’t make the loud sound of cooling. It is very rare now and used to be more often before.
- Applications like MS words, MS Excel etc open slightly faster.
- Games like Counter-Strike GO and MK4 11 – Komplete edition etc feel more responsive and fluid.
- Battery lasts at least 15 mins longer. (without battery saver).
- Multi-tasking, multiple desktops are much smoother
- File transfer are bit faster.
So, overall, it was totally worth it!! 👻
