Take fully apart...smash on the ground...put back together all the pieces with hot glue....than go out and buy a new one.
oh and by the way im having a similar prob but its at after it start up windows...it will have hiccups every 2-3 seconds and eventually freeze completely.

MY son had a similiar problem. I looked it over and discovered that the DC plug seemed loose. I dont have experience in working on computers but have electronics background. I dissasembled the whole thing. ..Many screws and a small metal clip Had no broblems but it was tricky. I didnot disconnect anything keyboard,display. I did remove the HD. I found that one of the electrical connections frpm the DC socket to the motherboard had come loose. Intermittant connection.. I resoldered the connection but noticed that the socket was a little wobbly. I used some instant glue to secure the plastic socket to the MB and everything works fine now. Saved my son a few hundred dollard and a repair tech said it was a MB problem. Dissambly did take some time Manny screws... I worked with a static wrist strap, on a static mat amd bare feet. Tye power socket is only held in place by 3 solder connections and looking at them with a magnifying glass I could see that one was cracked

I'm currently going through this right now with an compaq 2190us and I believe it has something to do with the memory slots. I believe they have lost their ability to keep presure on ram causing a loss of connection during use , hence ending in eventual overheating. I replaced the processor with several others equal and greater in capicity and the problem was still there. I believe the memory slot is bad I will see I can add one from a working machine. Good luck

That is an odd problem, however, I would not recommend you disassemble your laptop unless you are either mechanically inclined, can afford to damage it beyond repair or have previous laptop disassembly experience. Having said that I would check the following before taking anything apart: -Is it getting power; a quick check is to see if your battery is fully charged. -If you are starting your laptop cold (its been off for at least an hour) overheating probably isn?t a factor unless something catastrophic is wrong. Cleaning probably won?t accomplish anything. -Open the memory compartment, remove and reseat the module. I?ve had several cases where this has worked loose. - Have you recently replaced or added hardware to your laptop or upgraded firmware? If you have and you can undo safely try that next. If that all fails I would suggest that this is probably a repair best left to the local authorized Compaq repair shop. Failure to boot without any type of error messages being displayed are usually fairly serious and requires repair parts and diagnostic equipment.

I agree, recycling like that for me has usually been a faulty processor (power surge or massive overheating), an overheating processor (faulty CPU fan or system, excessive dust), or another failed component. I recently had a Dell desktop display the same symptoms due to defective capacitors on the main board.
Anyway if you?re starting the laptop cold it is unlikely it could overheat that fast unless something major is wrong like a power short; that you would probably smell as well. So your fault is likly with a component on the main board.
Most if not all laptop CPUs are not socketed these days. Too many reliability issues with thermal expansion and rough handling thus they are soldered onto the carrier board. Again I wouldn't try to replace a laptop processor or other integrated circuit unless you have the specialized equipment, skills and experience required to properly remove and reattach LCC devices. If you go this route you'll likely create other problems on your main boards which will make it that much more expensive to repair.

If you do a Google search on your PC with the word "disassemble" or "repair instructions" you will likely get a hit. After you carefully get the motherboard out, the problem is typically bad solder joints on the dc port to motherboard. Make sure to use the least heat (that is, lowest wattage soldering iron) possible to remelt the solder. There are a few sites you can Google for "dc power port repair." If you are unable to do this many small firms advertise the service. Good luck

Try removing the battery (which may be bad) and only have ac power connected.

i think the battery is depleted so the power supply can no longer charge the battery

Usually answered in minutes!
it doesn't matter when i try to start the laptop it continues to cycle on and off from the time i push the power button, so i am not getting any error messages.
i am a a+ technician but i never seen a case like this before so i didn't want to break anything unless it was meant to broken to get at the last screws. i have tried resetting the memory, starting with the recovery disc installed, just the battery installed, just the power cord installed. i have installed a new battery (the battery charges ok with the laptop). i mainly want to take the cpu and change it but i can't get to it (i think the overheating fried the cpu).
