    Hi I would like to update my hp Envy 1050nr processor from 720QM to 820QM. Have anyone tried to do this? Is it possible to do this without changing motherboard and unlocking bios? Is there is any heat problems related to 820QM?

    Other question.

    Have anyone upgraded from 3 Gb/s to 6 Gb/s ssd? Is there is huge speed difference on laptop?

    Thanks :)

    I don't believe this is possible with this laptop. The processors are usually soldered onto the motherboard and are not interchangeable. Unless this laptop is different which someone please correct me if I am wrong.

    Changing processor from 720QM to 820QM is perfectly fine and supported.

    PM55 does not support SATA3 (6Gb/s).

    Are you certain the CPU is not affixed to the mobo with adhesive, as was done with the GPU (which cannot be replaced).

    That would work fine. I know because I've upgraded from an i7-720qm to an i7-840qm. Just pull the old chip out and replace with the new one. No adhesives to remove or anything like that.

    Just make sure to take the standard precautions associated with CPU upgrades:

    1. make sure you have TIM and TIM cleaner
    2. Upgrade to the latest bios (f2.b)

    Having upgraded mine, temperatures under load fell from 90 to 83-84 degrees - even taking into account the higher clock speed. However may not be the case for you. The TIM that you use will have an effect, as will the specific cpu that you use.

    By TIM (Thermal Insulating Material?) you mean thermal paste? It definitely makes a difference based on what kind you use and how well you apply it. For cleaning, isopropyl (rubbing alcohol) should work just fine as well.
