Laptop

where is the reset button on a compaq laptop.> mine is in the shop right now, and i do not think the guy knows his stuff. the page would come up black with ,start in safe mode, exc. 20 second count down, then a blue page that no human eye can read,but i did catch f9. then back to black screen. i need help fast. the guy is expensive, and he ain't gettin no where either.

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.

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 toshiba satellite a135-s4427 won't start up. every time i press the power button the light appears and shuts off immediately. nothing happens on the screen.

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
