    Hi, According to Lenovo, the supported processors for the MB in that Laptop supports only:

    3rd generation Intel Core i5-3210M
    2nd generation Intel Core i3-2370M
    Intel Celeron B820 (1.60GHz, 2 MB )

    That model uses a ( rPGA988B ) socket which is also called socket G2.
    If you can find a processor in that socket, it maybe supported with a BIOS update. Lenovo locks certain BIOS to use diff chips.


    My Best suggestion, contact Lenovo Support and see if they can give you a better answer.
    But thats the information I found on google with a quick search of the model laptop you have.

    Hi Solara2xb,

    Thanks!

    That means i have the highest possible processor in that laptop. Sad news for me. When I bought that laptop, its specifications said that it can support only 8Gb max of RAM, but I have 16 GB already running in there. In the pdf (http://www.lenovo.com/shop/emea/cont...-datasheet.pdf) on the first page it self it is saying that the max memory is 8GB but second page memory section says up to 16GB. That's for the memory which i have already tried, tested and working fine. Now, I wish if there is a way to determine if there is a possibility of CPU upgrade.

    The laptop has "Mobile Intel HM76 Express Chipset" and as per this pdf (http://www.lenovo.com/psref/pdf/3book.pdf page 31) from Lenovo it has i7 3612QM in other configuration with same chipset.

    Is there anyone who has tried something similar. I will be really thankful getting help on the same. There is no question asking Lenovo as they will simply deny upgrade support. That's why I am seeking community help.

    Another quick search gives me following guide (list of supported processors)

    CPU-Upgrade: Intel HM76 Express chipset processor support

    in which the highest possible supported processor is i7-3840QM (rPGA988.

    And as per comparison (http://cpuboss.com/cpus/Intel-Core-i...-Core-i5-3210M), the above is more than sufficient for me. If someone can help me on deciding on if I can really upgrade and get it working in machine. is there and bios unlocking required for that or just install the processor and it will run.

    We really cant offer much help because we don't have that model. Like he said below, the OEM can and often does lock out certain CPUs from working with a certain model of laptop on purpose. This is to make sure you do not 1. Add a cpu that the current cooling solution can not handle. 2. Upgrade to specs close or above what they want to see you. As in if you want option B you need to upgrade to this model here. 3. Intel told them to lock it out for some reason you will NEVER know. I used to work with a lot of these OEMs. Currently hold certifications by all of them.

    So you need to think of the what if it does not work scenario. Is it a very common cpu that you can resell in short order? Do you have something else you can stick it in? Can you afford to sit on that CPU if it does not work? Is it really worth the risk to your system to go a little bit faster? Is you laptop currently under warranty? Will this upgrade void your warranty? Most likely that answer will be Yes.

    Have you done any kind of laptop repair before? Lenovo is one of the hardest laptops to get back together without jacking something up. Run a screw through a cable by mistake because their cable hold downs suck ass.

    just want you to be sure of what you are doing first.
