    hello everyone,

    I have 2 laptops from acer, one of them is totally broken and i want to recycle it's CPU.

    So I want to place a Core i5 450m into my 4820TG-334G32Mn equipped with a Core i3 330M.

    the socket seems to be the same, but when i put the i5 in replacement of the i3, the computer don't want to boot, i have a black screen.

    When i put back the i3 everything is fine.

    I think that i'm missing a tune, is there any solution to put the i5 450 ?
    if not , is there any better cpu than the i3 330 to fit into my 4820TG :confused:

    thanks for your help !

    Update BIOS first, then upgrade the CPU- 450M might not be recognized.

    The I5-450M should work. Let us know what happens after the bios is updated. My Acer was an I3-370M and I upgraded it first to an I5-450M and then an I5-540M.

    hello,

    I have also 2 laptops from acer, one of them is broken screens and i want to put CPU i7 740QM from my ICONIA in my aspire 4820tg-488g75mnkk.

    So my 4820TG-488G75Mnkk equipped with a Core i5 480M.

    the socket seems to be the same PGA988, but when i put the i7 in replacement of the i5, the computer don't want to start, the power button only blink once....and then nothing.

    When i put back the i5 everything is fine.

    aspire is updated with latest bios 1.25 before test with new CPU...
    in "read me" file from bios it's look bios support CORE Clarksfield of i7-740qm

    i need advise what to do>>???!?!!?

    stankolima the i7 in technology terms is a downgrade 45nm cpu no integrated gpu vs your i5 32nm cpu and igpu at 35w vs the i7 at 45w. I would swap a 740qm for a i5 480m anyday of the weak. The i7 will only be 20% fast and take around 50% more power consumption and heat up and take away probably 1 hour in battery life.
