Great Mystery Compaq Presario 1200XL Laptop
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. |

I assume your question is since Any contact is subject to interruption, even those using gold to prevent corrosion. Temperature changes often are enough to move such contacts and provide an intermittent contact. It really is not magic at all. I cannot say definitively that this is his problem, but that is one area I would eliminate before suspecting others. It would also be nice to have an explanation of exactly what is happening with respect to his failure to boot. |

True, but it's hard to see how that would explain the bizarre behavior the O.P. reported (what, do the memory chips magically unseat themselves, then reseat themselves in the interval?). Easy to explain: the notebook has a (large) capacitor that is across the backup battery so that when that battery is replaced, the settings are not lost. He removes the backup battery, then in the (couple of weeks) time the capacitor finally discharges and the configuration settings are lost, and the computer can reboot. Many of these (not all!) have a jumper somewhere that will short that capacitor to give the same effect. Above reply does make assumptions as to what teh OP is doing, however. g |

I don't get it; how would the settings not being lost lead to the computer not being bootable? This would seem to defeat the whole purpose of nonvolatile configuration settings, unless I'm missing something obvious in your reply. -- Made From Pears: Pretty good chance that the product is at least mostly pears.

This would seem to defeat the whole purpose of nonvolatile configuration settings, unless I'm missing something obvious in your reply. Corrupted hard drive data... I've seen it happen where it would only boot if the computer NVRAM data was set to factory specs (telling the BIOS to find out what the drive is). Very rare... But then again, the OP's problem seems a bit unusual, too! g |
