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 HP.com. 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.

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?
