    It's "alive" again (second time)! After a few months of storage (RTC/CMOS
    battery removed), I hooked it up and it boots up!!! This is the second time
    this Compaq Presario 1200XL needed a long rest before coming back to
    "life"!!!! NOTE: When it "dies", it will not boot up a few days to a week
    afterwards. I had tried this procedure both times, but this "mystery" laptop
    needs a long "rest" before it can be brought back to "life"!.

    I "flashed" the BIOS via SP15611.EXE Rom Paq downloaded
    from I installed a new RTC battery, but I will keep the main
    battery removed. NOTE: The first time it "died", the main battery was
    installed. The second time it "died", the main battery wasn't installed.

    I will no longer use this "mystery" laptop for anything important on the
    chance it will "die" again.


    Before you type your password, credit card number, etc.,
    be sure there is no active keystroke logger (spyware) in your PC.

    Previous Post(s) from the past:

    I found hundreds of postings regarding the Presario 1200XL series laptop
    with the same or similar problem as I have (see my original post below).

    It is my impression that one common cause of this problem is the flash
    bios going bad. It seems that somehow, there is a connection with a dead
    RTC/CMOS battery and flash bios!!! I replaced my dead RTC/CMOS
    battery (like many others did), but that isn't enough.

    I read several reports that stated the laptop was brought back to life
    after the flash bios was replaced, along with a new RTC/CMOS battery.

    My impression is the 1200XL series is a LEMON or this was designed
    into the system so the laptop last for as long as the RTC/CMOS battery?
