Upgrading CPU on HP laptops. Is it worth it? Is the CPU or Processor upgrade procedure complicated? How long does it take? These are common questions in regard to upgrading from the factory original processor that ships with many laptops. In the following article, I discuss my experience in regard to working with and upgrading CPU on HP laptops; in particular the HP DV6000, DV9000 series laptops.
HP CPU Processor Replacement Video
Here is a nice, yet simple video clip direct from HP outlining the Processor replacement process on a Laptop. While this video does not cover every specific DV6000 or DV9000 variation, it provides a very clear high level overview of what to expect during the teardown and reassembly process.
Replacing a CPU on HP Laptops
I have personally replaced the factory original T5450 processor in a HP DV9548us laptop with a new T7500 and can honestly say that the procedure was relatively painless and well worth the effort and cost. At the time, this upgrade resulted in noticeably better system responsiveness, improved multitasking performance, and smoother overall operation when running multiple applications.
However, I strongly recommend downloading the HP DV9500, DV9600, DV9700 service manual and thoroughly reading from page 55 to page 104 of the "component replacement procedures" section before you begin. HP service manuals are extremely detailed and provide step by step instructions, diagrams, screw locations, and cable routing paths that are invaluable during a full laptop teardown.
What Is Involved in a CPU Upgrade?
In order to remove and replace the T5450 processor on the HP DV6000 and DV9000 series laptops, the entire motherboard must be removed from the case. This is not a quick access panel upgrade like you might see on desktop computers. You will be removing the top covers, keyboard, screen assembly, wireless antenna cables, cooling assembly, and the board cover plate before the motherboard can be safely lifted out.
The CPU replacement process should take between 3 to 5 hours from start to finish if you have never worked on a laptop before. If you have prior laptop repair experience, you may be able to complete the job faster, but it is still wise to set aside an entire afternoon so you do not feel rushed.
Probably the toughest and most involved part of tearing down and reassembling an HP laptop is removing and reconnecting ziff connectors. Ziff connectors are those tiny ribbon cables used throughout the laptop to connect components such as the keyboard, touchpad, power button board, and display controls to the motherboard. If you are not careful with these fragile ziff connectors, it is very easy to tear a ribbon cable or snap a locking tab.
Tools and Preparation
Before starting the upgrade, make sure you have the proper tools and a clean work environment. At a minimum, you will want a small Phillips screwdriver set, a plastic pry tool or spudger, and a container or magnetic mat to organize screws. HP laptops often use many different screw lengths, and mixing them up can cause problems during reassembly.
It is also a good idea to use an anti static wrist strap or at least ground yourself periodically while working. While CPUs themselves are fairly robust, static discharge can damage sensitive components on the motherboard.
Thermal Paste and Cooling Considerations
When upgrading the CPU, you should always clean off the old thermal paste from both the heatsink and the processor using isopropyl alcohol and a lint free cloth. Apply a fresh, high quality thermal compound before reinstalling the cooling assembly. Proper thermal contact is critical to prevent overheating and thermal throttling after the upgrade.
Take a moment to clean dust buildup from the cooling fan and heatsink fins as well. Many older DV6000 and DV9000 laptops suffer from heat related issues, and improved airflow can significantly extend the life of the system.
Is a CPU Upgrade Worth It?
In my experience, upgrading the CPU on an HP DV6000 or DV9000 series laptop can absolutely be worth it, especially if the system is otherwise in good condition. These models often shipped with entry level processors that can feel sluggish by modern standards. A compatible higher end processor can breathe new life into the machine for basic tasks like web browsing, office work, and light media use.
That said, it is important to consider the age of the laptop, the cost of the replacement processor, and whether other upgrades such as adding more RAM or switching to an SSD might offer better performance gains for less effort.
Final Thoughts
I personally feel that anyone with a working knowledge of computer hardware and components should be able to successfully replace or upgrade a T5450 processor in an HP laptop. Just make sure you have a comfortable and clean workbench to use, follow the HP service manual closely, and give yourself plenty of time to complete the project without rushing.
For those who enjoy hands on projects and want to extend the useful life of an older HP laptop, a CPU upgrade can be a rewarding and educational experience.
