Hi,

I have a Compaq Presario 1200XL laptop computer that one day,
would not power up. I tried another power supply, replaced a dead
RTC/cmos battery, etc. I removed the RTC battery, main battery, and put it
away. A month later, I decided to try it again. It powered up!
Everything seemed just fine, but it only lasted for a couple days before it
happened again. Again, I put it away. A month or so later, it powered
up and again everything seemed just fine. I downloaded ROM Paq
SP15611 and I "flashed" the bios. About a day and 1/2 later, the
laptop "died". Now it won't boot up. Again after a long rest period,
it came back to "life", but for how long? Note: It won't power up
after a week's "rest", but it will power up after a longer rest such as a
month!

Did anyone have the same experience with this or similar model laptop?

Thanks in advance, Brad

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


By not booting up I assume you mean there is no text of any kind on the
display? Or do you mean it does not reach the operating system?

If it were my computer the first thing I would do is clean the contacts
of the RAM. It sounds a lot like a bad connection and the RAM is
essential to it booting to even a bios screen for most computers.
