    I have replaced the RTC/CMOS batteries on some of my
    old laptops, and it is a big help if I know in advance the location
    of that battery.

    I failed to find the location of this battery on the web for my HP
    Pavilion N3390 laptop. Note: I was ripped off at
    when I was misled with their claim to have a service manual. What I paid
    for turned out to be a user manual (I already have).

    I will be very grateful to anyone who can tell me the location of the
    CMOS battery.

    Thank You in advance, John

    I would have thought that this battery would be a user replaceable
    item, in which case it should be identified in the user manual.

    If it's not a user replaceable item, then perhaps it is integrated
    into the RTC/CMOS RAM IC. Do you see any "fat" ICs?
