Processor also known as CPU

Laptop processor CPU

A processor also known as CPU (Central Processing Unit) is the brain of a laptop computer. The processor is one of the main components in a laptop. Laptop processors are made mainly by Intel and AMD.

The processor connects directly to the system board via a processor socket aka CPU socket as it shown on the picture below.

QUESTIONS AND ANSWERS.

Question: Can I overclock the CPU in my laptop?
Answer: No, you cannot. In most laptops the BIOS doesn’t give you this option.

Question: Can I upgrade the CPU in my laptop?
Answer: Unfortunately, laptop manufacturer’s do not provide this information to general public. Yes, it’s possible on some laptops. You’ll have to find a new CPU which fits the same socket and try it.

Question: Are CPU failures very common?
Answer: No, they are not. CPUs fail rarely. If your laptop stopped booting, the CPU will be the last component to blame. Check the memory and motherboard first.

    Why would you upgrade processor? Its too expensive.
    Max memory and install faster hard drive.

  2. Repair Man says:

    Anon,
    Of course, upgrading from Pentium 2.0GHz to Pentium 2.2GHz doesn’t make a lot of sense. But what if it’s possible to upgrade your Celeron CPU to a Pentium CPU and boost the laptop performance?
    I agree with you on upgrading the hard drive and memory. Max these components first and then think about upgrading the CPU.

    hi all!
    i want to cleaning my laptop and replace thermal paste. what is good paste for laptops?

  4. Repair Man says:

    neil,

    what is good paste for laptops?

    I know that many people like Arctic Silver thermal compound. Google it and you’ll find it.

  5. Serge Belov says:

    Fixing an old Sony laptop for my friend. The laptop shuts down while running multiple programs. I know that laptop overheats and would like to replace thermal paste but I cannot remove the heat sink.
    I even purchased a service manual and doing everything right. I loosened all screws on the heat sink but still cannot separate it from the processor. Should I remove it with some force?
    Thank you, Serge B.

  6. Repair Man says:

    Serge Belov,

    I loosened all screws on the heat sink but still cannot separate it from the processor. Should I remove it with some force?

    Most likely the old thermal compound has dried out and glued the processor to the heat sink. In some cases you’ll have to apply some force in order to separate the heat sink from the processor. When you do that, the CPU might come out attached to the heat sink.
    If that’s the case do the following:
    1. Very carefully separate the processor from the heat sink with a flat head screwdriver.
    2. Unlock the processor socket on the motherboard, insert the processor and lock it in.
    3. Now, when the processor is installed back into the socket and secured, you can remove the old thermal compound.

    Do you know a good thermal grease for laptops? What is a good reliable brand I should buy?

  8. Repair Man says:

    Russel R,

    Do you know a good thermal grease for laptops?

    I’m work mostly with warranty laptops and use thermal grease supplied by the manufacturer but I know that many people prefer Arctic Silver thermal compound.

    Hi, I have a bad Fujitsu laptop that has a motherboard. From what I’ve read here, I understand that fixing a motherboard would be very costly and not worth it. So I’m wondering if I could sell some parts from my laptop. Would be able to separate and sell the processor etc?

  10. Repair Man says:

    Leo,

    From what I’ve read here, I understand that fixing a motherboard would be very costly and not worth it. So I’m wondering if I could sell some parts from my laptop.

    Sure, you can sell many different parts from your laptop. You should be able to sell at least the following most common and requested parts: keyboard, memory modules, CD/DVD drive, LCD screen, screen inverter.

    Would be able to separate and sell the processor?

    Most likely you can separate the processor. It depends on the model of your laptops.

    rojen salino,

    i just want to ask if what is the most expensive parts of laptop. because my auntie’s laptop was damage. she said one of its part has been broken.i just want to know if u have an idea if what it is.

    The most expensive parts in a laptop are the motherboard and LCD screen.

    my pictures and important documents were saved ion her laptop. is there any way to get the pics even it is damage? is there any part to be removed in order to get my pics and docs again.

    You can recover your documents from the hard drive using an external USB eclosure.
    1. You remove the hard drive and I assume it’s not damaged.
    2. You install this hard drive into an external USB enclosure.
    3. You connect this USB enclosure to another working computer.
    4. When the drive appears in My Computer, you access the drive and back up all personal files.

    paulopopas,

    i got one toshiba with one processor 1.8ghz can i change for one bigger?

    Most likely yes, if there is one that fits the CPU socket.

  18. Steve says:

    Hey. I was thinking of upgrading my processor in my Laptop, a Toshiba A305-S6905. It has intel cor 2 duo t6400 (2.0, etc) and was wondering if replacing it to the intel core 2 quad Q9000 (2.0 etc..) on the intel site, its the same socket. I think it would make a difference, do you?

    Also, the laptop has 4gb of ram, may bring to 8 later, and runs win 7 64bit (yes, its a 64 bit system even though it came with 32 bit Vista)

  19. Repair Man says:

    Steve,

    I was thinking of upgrading my processor in my Laptop, a Toshiba A305-S6905. It has intel cor 2 duo t6400 (2.0, etc) and was wondering if replacing it to the intel core 2 quad Q9000 (2.0 etc..) on the intel site, its the same socket. I think it would make a difference, do you?

    To be honest, I don’t know if you will see any improvement in the laptop performance after this expensive upgrade. I’m working on 3-5 year old laptops and they work just fine for me.
    You can boots the laptop performance if you upgrade from a 5400RPM hard drive to a 7200RPM hard drive and you’ll see the difference after that.

  20. Steve says:

    In repsonse to Repair Man, Now after that upgrade to the harddrive (which I do notice a difference, by the way, Thanks), would that 4gb of additional ram be worth it? considering laptops have standard of 2 slots, and so far 2 2gb sticks are in, Would replacing them with 2 4gb sticks be worth it or not? and I’v checked with Everest software and it says that they can handle 8 gigs.

    it has DDR2-800 in it (a corsair and a Samsung(came with))

    Everest says these are supported memory types. DDR2-667 SDRAM, DDR2-800 SDRAM, DDR3-667 SDRAM, DDR3-800 SDRAM, DDR3-1066 SDRAM

    any suggestions? or should I just leave it be.

  21. Repair Man says:

    Steve,

    would that 4gb of additional ram be worth it? considering laptops have standard of 2 slots, and so far 2 2gb sticks are in, Would replacing them with 2 4gb sticks be worth it or not? and I’v checked with Everest software and it says that they can handle 8 gigs.

    Yes, if the laptop can handle 8GB. I would go for it.
    There shouldn’t be any problem with the OS because you are running a 64-bit OS.

    my laptop doesn’t beep and no display on the lcd. could this be a processor problem, or is the mother board fried?

  23. Duaine says:

    I have a Toshiba Satellite A15-S129 that has a 2.4 GHz mobile celeron processor and it is easy to access it to replace it.
    Is there a better or faster processor I could use, such as a Pentium 4?

  24. Repair Man says:

    Duaine,

    Intel 2.20GHz P4

    I checked parts listed for Toshiba Satellite A15 laptop and along with Celeron 2.4GHz they mention Pentium 4 2.2GHz for same motherboard.
    I think you can use this one. This is my guess.

  25. Evi says:

    I know, I’m asking questions about everything :P. I have an AMD CPU. I’m going to build my own computer, would you suggest AMD or Intel? Intel is more credible to me, but I don’t know much about AMD. I suppose it would depend on what the computer is for?

  26. Repair Man says:

    Evi,

    I know, I’m asking questions about everything :P . I have an AMD CPU. I’m going to build my own computer, would you suggest AMD or Intel? Intel is more credible to me, but I don’t know much about AMD.

    I would go with Intel.

  27. Evi says:

    Yeah, I’ve figured that out since. Thanks for answering though. I chose an i5 Intel. AMD is nice when you want a budget computer :P.

  29. Repair Man says:

    hardik,

    i have compaq presario c795tu ,in my laptop lan is working but not bluetooth ,i want to know can i know that my laptop has bluetooth hardware or not without touching any hardware

    Take a look in the device manager. If you have Bluetooth module in the laptop, it will appear in the device manager.
    If you don’t have it, you can buy a small USB Bluetooth plug. It’s small and you don’t have to disassemble the laptop.

  39. Stuart Gentle says:

    I’ve got a hanging problem… My laptop hangs or freezes when i’m using it… I have to force shut down and on again. It started minute and has now become very severe. Now you’d say memory problem, but still gat close to 324GB free space and recently restored the system with some repairs stuff my technician used to clean the system up to its initial 500GB space, yet it still hangs.
    He said he later tried using other laptop parts to confirm what parts were affected and they all worked. Except the Processor. He couldn’t find a similar working processor to check it out…

    Please proffer a solution for me.

    And does hanging have anything to do with the processor?
