    My laptop CPU recently died so I need a replacement. What are the best compatible cpus that I can use?
    My cpu is a Intel Core 2 Duo T5750 clocked at 2.00 GHZ , it has an FSB of 600 and it is a socket P processor.

    My laptop specs are :
    Intel core 2 Duo T5750
    4 GB RAM
    nVidia GeForce GS 8400M 256MB


    Thanks in advance

    How do you know it's the cpu?
    It could be the dreaded GPU overheating issue.

    Because when using HWMonitor I used to always notice that the GPUs tempeture was always in a good range, but the CPUs tempeture was 15C higher than maximum tempeture.

    When you mean died what does it mean no video or not bootup or ???? We need more info as these very models of HP has a track history of GPU failure unrelated to CPU dying or any sort. Also it would seems to indicate that you didn't clean or disassemble the laptop and clean out the dust buildups or redo the thermal paste on your CPU or GPU to assist in keeping the system running more efficiently. That high temp on CPU could be the result of clogged vents causing overheating and causing it to shutdown to protect itself from burning out.

    You are 100% right I've heard about GPU failures but I know that in this case it isn't that, like I said In the previous post the GPU temps were fine only the CPUs temps were high. You are also right on the clogged vents, last time I cleaned the vents I didn't do a good job, the computer used to shut down to protect itself as you said, last time it shut down of overheating it never woke up. Now can you please give me a list of some good CPUs I can use?

    From my experience and knowledge it's not the CPU.
    Your GPU is weakening becoming desolder.
    Does your wifi shut off too?

    If it is your CPU then that would be the first for HP DV6000 series that I have come across.

    Seriously it's the gpu

    I posted a write up about temps and what do for better cooling.
    Check the General area or search my name as I have 10 or so posts.
    It's called lower your GPU by 10C in 2 min for less than $3.

    good luck
    they are easy to fix
    lots of youtube videos
    look for the directions with the guy that uses the 8 quarters and 2 nickles
    pm me and I will try to send you the link

    his approach is good and works

    read my thread and I think you can have a perma fix too.
    mot ppl never put back a copper shim so it desolders again and fails

    Ok thanks. I don't have much experience in the laptop world, only the desktop world. But let me explain the symptoms on my laptop before it failed. when the computer got hot it used to shut of, when I tried to turn it back on immediately it didn't start up, when I left it for a few minutes to cool it used to start up. That's why I think it's the CPU and not the GPU. Are you still sure it's the GPU?
    And why did you ask me about the wifi?

    Can you send the link you mentioned above please?

    Thank you

    That is the GPU as you just diagnosed yourself dying GPU will exhibit that problem. The only way to fix is to reflow the GPU or swap the motherboard for another that someone has reflowed the board to fix the problem. CPU failures especially Intel failures are rare but do occur but the symptoms you describe is a GPU that will fail. Your choices are to reflow the GPU and get a better thermal conductor between the heat sink and GPU or swap your motherboard-it's not when it will fail as it will fail. They ask wifi cause everything is in one form or another connected to the operation of the laptop if your can't get to wifi means your CPU is not working but if you can that means the CPU isn't the problem. Those are simple test you must do to eliminate what the causes are. If this doesn't tell you more then nothing more anyone says will help your problem.

    Yes but I don't get the black screen of death, the computer just doesn't boot, if it was the GPU all lights would turn on expect for the screen but in my case the only light that turns on is the DC jack light ( when I connect the power cable )

    That doesn't indicate anything other then the board is getting power. Computer doesn't boot aka black screen of death is the same. All lights would come on doesn't tell much just that the board is getting power. If you bios doesn't detected a GPU nothing is going to show on the screen and you will get a black screen. You're trying to go down a road that the rest has told you that you will need to reflow the GPU and get a reflowed motherboard that has the GPU failure fixed. Those are your only two options as this point in time. I seen and read to many failure with the defective soldering of the GPU that was problematic with the dv2000, dv6000, dv9000 series of laptop from hp and they never acknowledge the problem and there are plenty of reporting online that Nvidia knew of this problem and never fixed the problem. This came down to making a profit and not fixing the problem as the recall would eat at their profits both of Nvidia and HP.

    I don't much about laptops, but when I saw on the Internet this problem about the GPU all lights would turn expect the screen. In my case I know the board is getting power as you said earlier but the computer doesn't show any light ( expect DC ), what I think is that it's like trying to boot whit no CPU, at least on desktops it's like this.

    You haven't listened to my or any other poster advice about your problem doing a simple search on your model number on the net will tell you more about this hp laptop problems already. As you stated clearly you haven't taken the time to learn about your laptop and the problems associated with it. Your not trying to fix your problem and replacing the CPU is the least of your problem-it's the GPU and you will either have a book weight or fix it to get it to work. No amount of talking about replacing the CPU here is going to fix it.

    Your trying to compare two different designs that aren't the same system. No CPU the bios will either beep at your or will not boot and immediatly shutdown or give you warnings it doesn't detect the CPU. Those two system are designed differently and have different setups and shouldn't be compared as though they are the same system.
