I've seen several of these. All have been the connector. On the bottom of you on/off switch is what Compaq calls a button board. This board if OK but it plus into a connector on the mother board. If you look at this connector closely with a magnifying glass as you attempt to remove the button board you'll notice that the connector is coming off the mother board. The pins for this connector are almost as thin as a human hair. I don't know of any way to repair this. HP is only illing to sell a new mother brd. Good luck.

Compaq presario b1900 fails to give output to monitor. If output comes out it gives blue screen and shuts down. If you switch on again the fan and disk do run but no output to screen. An external monitor...

That blue screen and shut down, means a problem on both OS and Hardisk.
If you got any hardisk for that laptop. try it and am sure it will work.
The faint beep means a good memory card.

Hope that helps!

My Compaq 6735s laptopwill not cut on

Well lets look at the likely options and then discuss.

1. Power button
2. DC power jack
3. Bad motherboard

1. Power buttons seldom go bad and when they do it is usually related to a spill that usually takes out the system board. In my experiance bad power buttons usually dont click or dont click properly.

2. The power jacks often can cause a no power no boot condition but usually you have a clue because it starts acting up after being dropped or wriggling it will cause the power to come on and go off. Not always of course but usually.

3. If the laptop goes off and stays off while playing a game or working with the laptop on your bed or other soft surface. then you can usually suspect the video card went out or some other key system board chip has burned out due to heat or poor workmanship. Dropping the laptop can also cause this problem as can spills.
1. Get a new switch board off of ebay. Usually the power switch is on a little sub-board that is not that hard to replace. Ebay is a good source for laptop parts.
2. These dc jacks can often be resoldered or have wires bypass the weak areas. Sometimes they will break off enough system board to require replacing the board but usually if you have some soldering skills and basic electronic knowledge you can fix it yourself.
3. System board. Again Ebay is the most likely place to find something at a reasonable cost. unless you are mechanically inclined with some geekiness you may not want to try this replacement. There are lots of screws and small components and if you dont do it right you can seriously messup other components or your new systemboard.

Cooling fans compaq nx9010

well usually colling fans in laptops are always on. but i have encountered models that seem to temperature controlled, like the one my brother is using. as for the clearance if you can feel the heat of the laptop coming out from the keyboard, you'll need to atleast put some clearance underneath to properly disperse the heat.

Hi - What you see is the fan that cools the main processor:


It will spin to cool the processor when it gets hot so depending on the surrounding air temperature it may not spin. Usually you can feel it spin up briefly when the machine turns on, try placing your hand over the vent when you switch on. If the laptop seems to be running hot & the fan does not spin then you need to get it looked at as overheating will cause a failure in time.

Latitude C640 is dead!!

The only solution that I can think of would be a power jack problem. I would not advise replacing the power jack yourself since you have to take out the laptop mother board, de-solder the power jack then solder the new one on and put it back together. My advice would be to take it to a professional computer repair shop and have them take a look at it and replace the power jack. It is worth getting repaired since power jacks usually range $40-$70.
