    Hi Guys I need help I am having a wierd problem:

    I upgraded my RAM in my Unibody MacBook Pro from 2*1GB to 2*2GB i.e. 4GB but now when I plug in my charger the battery does not charge but if I shut down the system and take out the battery and plug in the charger then the system works with power adopter as the power source and subsequently when I put the battery in it starts charging but only once i.e. as soon as I remove the charger once and re plug it does not charge and If I repeat the process it follows the same pattern. Is it related to RAM, I bought Kingston RAM from an Authorised Apple Reseller.

    So just for clarity I shall re-iterate:
    1. Machine works with charger plugged in without battery
    2. Put the battery in -> Plug in the charger -> Still works -> Now Unplug the charger -> Plug it back in -> Now it does not charge:(

    Please help
